1000-1200 watt PSU for at Ryzen 3950X build. What can you recommend?

[Aquinus]

I have taken a look at seasonic PSU and there Seasonic Prime Ultra Platinum 1000 watt and not titanium looks pretty good hornestly. It´s black, has 12 year warranty and i am considering this one as it is prices lower than the titanium one. From where i buy PSU the Platinum is nearly 100 USD cheaper than the Titanium both 1000 watts. Would you guys still say its worth paying 100 YSD more to get a titanium rated PSU?

I probably wouldn't pay extra for the titanium one. My platinum runs pretty cool even under significant load. If you can get one or the other for a good price, I'd say go for it. Either of them will be good, but I'd be surprised if you noticed a difference between the two.

 

[Tomgang]

Perhaps a bit OT, but for the people here saying "1KW is enough" - this build will never exceed 500W unless the OP is running some seriously unsafe OCs. Even with a bunch of drives and fans a 3950X and a single 1080Ti is unlikely to top 450W in real-world use. Saying a 1000W PSU is "enough" for that is... a bit silly. 750W would likely be fine both for noise and longevity. 850W will be plenty. 1000W is overkill. 1200W is stupid.

i dont know how you get 450 watt. But that is deffently not system at full load then. GPU with overclock is up to 300 watt alone and CPU stock is about 144 watt as that is what AMD has set max watt to at 105 watt TDP and with overclock that will be higher when all cores runs a 100 % load. I think more the CPU can use up to around 200-250 watt when higly overclock. So that is alone 500-550 watt for GPU and CPU alone. Then every thing else comes on top on that. All from chipsæt to HDD and RGB light.

Personally I can't rate the Corsair models even the AXi units highly at all. All of the models I had died and to be honest where junk in comparision to the previous AX model range, that I may add I have 2 1200w units still working flawlessly..
Over the years I have drawn away from Corsair and I have been buying EVGA model units. Some have been the smaller 650w G+ models up to the T2 1600w unit. So far, I've had nothing but a simple and easy ownership of each of them.. They just work much like my AX units still do.. Very happy with them

I'd always suggest going a little higher than you need with a PSU, simply because of the efficiencies they suggest 50% etc, but as you've already mentioned some headroom in case you change setups and need some extra power..
Definitely a solid thumbs up from me from EVGA and a thumbs down from Corsair. I hear nothing but good about Seasonic as well. JonnyGuru is also the place to visit when you want PSU advise I think. Personally, I feel it's the only place to visit

I like EVGA too more than the rest probably. However you don't have to buy more due to efficiencies. That's a myth today. Modern psus MAINTAIN their efficiency thru out the range. There is no sweet spot. Buy what ya need, but don't way more to get a sweet spot as it doesn't exist. The more important spec is the hot box testing aka how (temp) hot they can run whilst providing rated wattage at what efficiency.

lmao, this! I've been trying to point that out lol.

It's like your in an arm stretching machine and they pull!!!

So, I'd get 1000w to have the ability to Run 2x monster Radeon VII GPUs (or any GPU capable of 250w draw and up)

Platinum for the build quality and 12 year warranty, which it will likely last that long with an above configuration.

But if you never plan to get a dual card setup, grab an 850w Platinum instead. Just my 2 cents, also, 850w should be plenty for mid ranged dual card setups too..

Dit not think either that paying 100 USD more is the way to go unless i have the PC on 24/7 and i dont have that at all.

Before my 1080 TI i al ways ran SLI, but it seems multi GPU is a dying breed. AMD dropped crossfire entirely on some cards and Nvidia only supports SLI on the more exspensive cards. As that is not bad in it self, game developers seems to drop SLI/crossfire support as well in new tittles. Youtubers like Jaytwocent and Tech Yes City has declared multi GPU dead as well. So i dont think i ever will be running SLI again sadly

I will be getting a 1000 watt. Better overkill than under kill. PSU is an important part of a PC and a under powered PSU is a bad idea and i want so i can upgrade with out thinking of getting a better PSU later.

PCIe Gen 4 is meaningless at the moment, it only affects sequential writes. So in the majority of cases the 970 evo plus/pro or the optane will be much faster than that corsair/crucial shit.

 

[Deleted member 185158]

Nothing wrong with 1000w. I have one too.

I have 2 of the seasonic ultra prime titanium 850s and really like them.


The new corsair ax series is seasonic OEM the reason I reccomended them as well.

I've used multiple evga psu in the past as well and never had any issues with them.

So PCIe is meaning less. I dissagree there. As PCIe Gen 4 SSD mature, there are potential for up to around 7500 MB/s read/ride speeds and Crucial is not shit, its not the fastes SSD´s, but they are dam reliable. I have used Crucial SSD since 2011 and never had one fail on me. I dont need fast sata SSD as they are purely to be used as game drives. That why i have NVMe for OS where a fast SSD is more importent.

RIP multi GPU. It was fun while it lasted.

Sadly yeah, multi GPU is a dying breed. But it whas fun the years i had it from 2009 to 2016 (got 1080 TI in 2017). Before that, i had GTX 285 in 3 way sli, GTX 570 in sli, GTX 970 In sli.

Look pass the wire mess. Back then i ditten care so much about look as i do know.

I think i have desided to go with Seasonic. It seems most are fond of them.

 

[freeagent]

Honestly I think you will be fine.. Save yourself a hundred bucks and take comfort in the fact you have a nice 1kw Seasonic powering your setup for at least a decade. My PSU is 7 or 8 years old and the rails really don't move much if at all. My setup in sig in that config only pulls 350 at the wall running the firestrike extreme loop.

Edit:

I ran furmark once with this setup and I think it was closer to 700w, pretty intense..

All from chipsæt to HDD and RGB light.

Nothing you're saying here is wrong except the conclusion. Tell me, how often are you running consistent 100% loads on your CPU and GPU at the same time? Unless this is a professional render rig, the answer is likely to be in the region of "almost never". Even if you overclock the CPU (which is a bit silly with Ryzen 3000, as you'll lose performance in lightly threaded situations) it won't come close to 100% load while gaming. If you're gaming and running a CPU encode you might end up stressing a bit more than half the cores, but not at 100%. Unless, that is, your main use case for the PC is to run FurMark+Prime95? But in all seriousness, again, 450W is a perfectly reasonable number for real-world use cases. Unless you're planning on running multi-GPU, 1000W is overkill. Period. If you want a 1000W PSU, go for it, but you don't need one. I'd go lower wattage and higher efficiency instead.

 

[Zach_01]

This system all stock clocks yes will consume about 450W peak.
Mine is peaking at 350W with no OC.
But...
If the OP wants to OC to the Max, everything he can as much as he can (he has the right to do as he like), this rig can easily catch the 600W (peak) point. So the 850W will come a little short if you want to keep load 60% max. 1000W is the right Power point IMHO.
When I purchase a PSU, I’m thinking 10years ahead.
What if the OP want next year to go with 250~300w GPU (god knows what will be out there next year) and OC it...? And/or will like to add all shorts of stuff in that PC.

When you Purchase 1.5~2k$ CPU/GPU combo the high quality PSU (~300$ for this PC) is kind of an obligation to those components, in my book, and I don’t consider to save the 50$, when you go that high with all the other parts.

Efficiency has nothing to do with the bill economy as it’s not worth it. But a higher efficiency PSU is made out of higher quality internals. Reliability. Typical (high quality) efficiency is Gold I would say, and Platinum for someone looking for something more.
Titanium is not worth it, unless it’s something really special.

PCI-E 4th gen SSDs have nothing to offer right now (like the RAID-0) except high sequential transfer rates. Unless you transfer massive amounts of data back and forth every day there is literally no other real benefit.

 

[Aquinus]

But in all seriousness, again, 450W is a perfectly reasonable number for real-world use cases.

A Vega 64 with the power limit raised can draw 330-watts alone. When gaming, I see 500-600 watts off the wall on a regular basis, even without touching the power cap on the GPU. Overclocking the GPU can bring it as high as 700w and north of 800w if I stress everything at once. The point of getting a large PSU is so you don't hit capacity because the more load you put on a PSU, the harder it's going to be working to give you what you need. It also won't run nearly as warm because 35-65% load tends to be a sweet spot when it comes to efficiency in a PSU. You size out a PSU for max draw on all situations, so you're never in a position where you hit capacity.

 

[EarthDog]

Most people has properly seen by now that i am planning to move away from X58 and on to a Ryzen 9 3950X build (in fact i have just put in a order for this CPU, so i am sure to get it before it´s potentially sold out just as 3900X whas for a long time) and my old PSU is over 10 years and still working perfect but i dont think it´s a wise dession to reuse such an old PSU in a new build. So i am gonna need a new one, i am just not much into what is hot and what is to avoid today when it comes to PSU. My old PSU is a Thermaltake Toughpower 1500 watt.

So what can people recommend in the 1000-1200 watt area of PSU?

In gennerel i want this from a PSU:
Silent and 140 MM fan or around that size.
Reliable so no cheap garbage please, i have my builds for a long time.
RGB fan is not a must throw, but is alright if the PSU have it as long the RGB can be turned on and off.
I prefer the PSU is black as i am trying to hold my build in a black theme.
Maybe I shut also point out that I do overclock my system as that will raise power consumption as well. CPU and GPU will be overclock.

The PSU will be powering this system for now.
AMD Ryzen 9 3950X cooled by a Noctua NH-D15 chromax black (yeah i know AMD recommend AIO, but i am not a fan of watercooling. So i hope a good aircooler can do the job)
ASUS ROG CROSSHAIR VIII HERO X570 board
G.skill TridenZ NEO 3600 MHz CL16-16-16-36 2 x 16 GB = 32 GB 1.35 volts this shut be Samsung B-die modules.
Corsair Force MP600 NVMe SSD Gen4 M.2 - 1TB
Crucial MX500 SATA SSD 2TB
WD GOLD DATACENTER CLASS 12 TB HDD

Besides that this hardware will be reused from my old X58 build:
EVGA GTX 1080 TI
Crucial MX300 2 TB SSD
WD RED NAS 4 TB HDD
Aqua Computer Aquaero 6 XT fan controller that has 12 high RPM 120 MM fans connected to it.

I didnt read anything after this so sorry if it was covered... but why such an overkill psu? With the system listed and overclocked, a quality 850W would be PLENTY. Getting more than that is a waste of money for no reason (listed in the first post).

People who want to use 50-60% of their PSU to be more efficient is ridiculous. The difference in efficiency across the entire rated points of a gold+ psu is a max of 3%.. from 50-75%...1%... yet you are paying a hell of a lot more...so sweetspot shweetspot...

I run a 7960x overclocked to 4.4ghz all c/t and a 2080ti also overclocked on a 750W psu. Unless I'm doing something jacked up like running small fft and furmark (lololol) at the same time, the fan on my 750w psu doesnt even spin up when gaming (evga g2 supernova).

In the last 15 years... I've went from a 550W Sunbeam (bang for your buck quality back in the day), to a 750W psu which covered builds from a highly o/c'd i7 920 with that 500W dual gpu from amd that was water cooled out of the factory to what I have now.

People loooooove to waste their cash for 'sweetspots and efficiency'... . Go look at psu reviews and look at the difference in efficiency, peeps. Or, go look at the 80 plus standards and see just how flat the efficiency curve for a 80 plus psu is....

Edit: take some time to look at this - https://www.techpowerup.com/forums/threads/jonnyguru-talks-about-power-supplies.261018/

I will be getting a 1000 watt. Better overkill than under kill

Overkill is 850W, bud. 1KW is just a waste of your money.

 

[Zach_01]

Just a crarification, and personal opinion...
For me when say I dont want to load the PSU over the 60, max 65%, has nothing to do about hitting peak efficiency for lower cost bill. Indeed, the most high quality PSUs have the efficiency curve almost a flat line for the majority of the load range. Most of them even surpass the specs at 50~60% load by 1~2%, but that is not the point. 1~3% or even 5% difference will reflect just a few $$ over entire year. Not worth to think that, unless its something that runs 24/7 with a serious load, like a miner or a server.
The point is elsewhere. Its about maximize life expectancy. I'm taking all possible precautions so I can replace the PSU when I need and/or want, and not when fail. Peak efficiency is cleaner output which also means less stress for the internals. Doing it's job at the most easy point. Also high quality/eff. modern PSUs deal much easier (close to peak efficiency) the ultra high speed transient loads... the way boost clocks are implemented today for modern GPUs/CPUs (Turing, Navi, ZEN2)
I never had to replaced a PSU that has failed.

First quality PSU I bought was 2004, a Enermax Liberty 500W 80+ (100€). Used it for 4 years and left it aside for a 750W PC power & Cooling 82% eff. (140€) that I kept for 11 years with multiple combinations. Last 4 years was loaded with a FX-8370 (since 2012) and a R9 390X (2015), a 450~500W draw, no OC. Still working today with that combo. The Enermax still working today on a PC with 250~300W draw.
I always spend extra for a PSU and never load it past 60~65% and that has worked for me well, for stability (voltage output) and reliability (long life).

A Vega 64 with the power limit raised can draw 330-watts alone. When gaming, I see 500-600 watts off the wall on a regular basis, even without touching the power cap on the GPU.

It also won't run nearly as warm because 35-65% load tends to be a sweet spot when it comes to efficiency in a PSU. You size out a PSU for max draw on all situations, so you're never in a position where you hit capacity.

...which is exactly why I said a 750W PSU would be fine and an 850W would be plenty - a 3950X and a 1080Ti will likely consume around 450W under load, and might hit 600W if pushed very hard with some serious OCs. A 1080Ti is not a Vega 64, and a 3950X is not an i7-3930K. Modern hardware has ever decreasing potential for clock and power scaling, as process nodes shrink and manufacturers design smarter and more adaptive clock and power monitoring and adjustment systems to extract maximum performance from a part. A 3950X won't consume 300W even in power virus loads unless you're doing ln2 overclocking, and the 1080Ti won't push far beyond 300W unless you're using exotic cooling and shunt mods. And then, again, there is the difference between real-world use cases and power viruses and benchmarks. Real world combined loads are never 100% CPU + 100% GPU unless you're doing rendering or something similar. So, again, 750 will be safely beyond the peak, worst-case, once-in-a-blue-moon power draw of a system like this, and 850W will have a nice margin on top of that.


As for efficiency curves, that thinking is terribly outdated at this point. Modern PSU designs have near-flat efficiency curves between ~20-100%, and "aiming for 50 at full load" to maximize efficiency is a remnant from old, outdated designs when efficiency curves were far more ... curved. Not to mention that modern high-end, high-efficiency PSUs are generally under-rated and can deliver 100% output for ages without complaint, unlike the norm a decade ago. Sure, capacitor aging is unavoidable, so some "overprovisioning" is smart to ensure the longevity of the PSU, but double the necessary output is just silly with modern PSU designs.

 

[Zach_01]

This combo (3950X+1080Ti) is for today... And when you want to upgrade later to some RTX3080TI or RX5900XT with 250-300W draw (unOCed) and want to beat the crap out of it because you like it and for no apparent reason, and load the PC with all kinds of stuff, and hitting the 650~700W point frequently that 850W is not "working" for me, for 10+ years usage, with the 20% overpovisioning. I want 50%.
650W + 50% = 975W

And when someone is spending 2K $ for a CPU (750$), mainboard (400$) and a GPU (that 1080Ti will eventually be replaced with something top tier, so 700~800$ if not more) is a moot point to try to save 100 or even 50$ to PSU... the most valuable and significant part of the PC. It is something that I never understand... ever.

 

[Eskimonster]

I would defo buy a 850w seasonic prime platinum for this build, plenty power and 12 y warranty.

 

[EarthDog]

The point is elsewhere. Its about maximize life expectancy. I'm taking all possible precautions so I can replace the PSU when I need and/or want, and not when fail.

my dude... that is what the warranty is for. The warranty covers the unit. A good unit should be able to run what is on the label for the life of its warranty. Now nobody would nor should do that, but to only use such 'little' of its output for that reason is going overboard to me. 650 to 700w use on a 850W psu is nothing! I wouldnt pay 10% ($50-$100) more for something I dont need.

Literally unless you are using multiple gpus or subambient cooling and benchmark competitively, there are few to no compelling reasons to ever get more than an 850W psu. That wattage will handle any ambiently cooled CPU up to/including HEDT and a single gpu, both overclocked, for the life of its warranty.

You mean like PSUs released this year?

https://www.techpowerup.com/review/corsair-rm-750-2019/2.html

Honestly, this doesn't really matter, but less efficiency does translate to more heat and heat is what's going to degrade your PSU. The OP clearly cares about longevity considering he's replacing an X58 machine, so why push it and not leave the option open for adding components in the future by having that headroom? PSUs also tend to become less efficient over time, so there's that too. So a very real question that needs to be asked is how will the PSU be holding up after 8 years of use? The bottom line though is that if you're not interested in long term longevity and you're not pushing the PSU to the limit, it's probably a waste. I think we can at least agree on that.

you do realize that in order to pass 80 Plus tiers it has to fit within their parameters, right? And those values fit, yes (3%)? If that graph started at zero instead of 80% and didnt exaggerate the shape, it would actually be pretty flat through the 20-100% curve... 3% or less on 80 Plus units.

You can ask my 750w evga g2 supernova how its handled abuse over the last several years as it's still managing with my highly overclocked 7960x and overclocked 2080ti today.

Some people just leave more meat on the bone than needed. This yields little real world benefits and costs a lot more to do it. So to each their own, but, with my $100, I'd rather take the family out to a nice dinner, upgrade the GPU another tier, or save it than to throw it away by excessive overprovisioning. I just hate to see BS reasons to justify getting one.
