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

[Zach_01]

Tomgang I hope you are enjoying this debate... And please let us know your decision.
May I ask what is your need of computing power? Why do you need a 16c/32t CPU with a 400$ mainboard?
Out of plain curiosity...

I have taken a look at seasonic PSU

And that is a good stopping point.
Seasonic is simply as good as it gets. I buy that brand whenever I can afford to.

So, I'd get 1000w to have the ability to Run 2x monster Radeon VII GPUs

Why two of them? They don't run in Crossfire, do they?

I recently built a Ryzen 3900X + X570 Aorus Xtreme rig with a Corsair HX1000 Platinum. I have a 360mm AIO, and a Vega64, I don't think I'm anywhere close making that PSU break the proverbial sweat. Gonna get a NAVI 23, pretty sure it isn't gonna be a problem for that PSU.

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.

I completely forgot to respond to this, but my other posts should sum it up. In short: those per-part numbers are likely accurate, but you can't simply add them together for realistic use cases - gaming doesn't stress the CPU even close to full power, and drives and other peripherals are never concurrently under full load (other than spin-up of HDDs during POST, I guess). Chipset is ~10W (under full load, less when its PCIe lanes aren't being stressed, mobo+RAM are another 15-ish watts (relatively steady), SSDs are ~5W each (peak, normally far less), HDDs are 10-15W under spin-up and far less in use, and fans average out at a couple of watts each. Which is why my Fury X (275W) + Ryzen 5 1600X (95W) + water loop (10W pump + three fans) + one m.2 and one 2.5" SSDs barely exceeds 400W at the wall while gaming - including the >=12% losses of my 80+ Gold PSU. Your CPU (and GPU, if overclocked very heavily) consume more power than mine, but not much when used under normal conditions. For reference, 400W at the wall at 88% efficiency means ~357W internally, 450W at the wall =~402W internally. IMO my 750W PSU is overkill even for this power hog of a GPU - remember that PSU ratings are for output, not input, so PSU losses are not counted.

Of course you are free to choose whatever you want, and longevity is an argument for padding the rated output somewhat, but 1000W is nonetheless complete overkill for any ambient-cooled single-GPU PC in 2019/2020. As for the "spend the money, the rest of the build deserves it" argument - that kind of falls apart if longevity is a factor - doesn't the next $2000 upgrade also then "deserve" a similarly brand-spanking new PSU with crispy clean outputs and fresh capacitors? Don't get me wrong, I buy all hardware with the intention of it lasting for a long time, but you are talking about spending ~50% more than necessary for no perceptible difference. If you buy a 400W GPU in five years, I have some serious doubts you'll feel comfortable using that with this PSU anyhow.

Yeah, I'll be replacing my PSU when I get a Navi 23 and a new CPU (currently thinking 3900X), but only because I want to further downsize to SFX or SFX-L. Not sure if I'll go for a Corsair Platinum or something like the new Fractal units, but nonetheless I definitely won't be moving above 750W no matter the power draw of that combo. It simply won't be necessary.

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.

Apologies for the late reply... Family time...
Well they kind of maintain their efficiency even judging by the reviews they peak in the middle of the watt range, it might only be a few percent, but its the peak

I've never really worried too much about what PSU I've had as long as it's a good one. I've had both of my AX units pulling it's rated 1200w from the wall and nothing has happened to these units. The 1200w P2 I use for my 5960X + SLI 1080 Ti's has been pushed hard as well pulling 1400w from the wall (not by myself but the previous owner) and still over a year later it's just carrying on without any issues at all

Getting a decent PSU for me is essential and yes most of us here I bet do over estimate the PSU size, but most of us here will overclock, add water cooling and so on, which will add some more watts to the overall total of what is pulled from the wall.
I do allow a little more on any PC I build but what I stand by more so than the wattage of the unit is the quality of the unit. I simply won't skimp on a crap PSU model. I pick only from the top tier of units, always have and always will. Overclocking back in the Duron and Thunderbird days made me realise that (Q-Tec 550w vs Enermax 380w, nuff said...) Also PC Power and Cooling units, they saved my hardware, so another reason for top tier units

I guess when you buy from the top tier of units anyways, you have even less of a worry about what size unit to buy as some/most (I'm not sure) will allow you to pull more watts than it states on the unit.. Example my AX1200 units where tested and they where able to pull 1600w+ from the wall in the review and remain stable, now that I do call impressive

But still, if @Tomgang plans on adding more to his system, extra GPUs or whatever the reserve is always there... Another take on it is that, why would you want to run something close to flat out all the time when you could buy something that's got a little more headroom and won't be near it's peak all the time (I use combi boilers as an example there) If 850w costs £100 and the 1000w unit is £150, then meh might as well stick with an 850w if it gives you an upgrade path. But the difference is when you buy the 1000w for the cost of £100 when it's on offer (call it a gold or platinum models) then you're not really wasting anything This is one of the reasons I have the PSUs I have currently Price

I'll shut up now

You do realize that 1200W at the wall on a 90% efficient unit is less than 1200W load on the psu (1080W), right? It should easily be working there as it is rated to do so. The rating is NOT what it pulls at the wall, but what the psu can output. The efficiency is added to what it pulls from the wall.

I know I had a wall meter plugged into an X58 rig with TRI SLI GTX 580's at the time, when I saw it going north of 1200w I was somewhat surprised and impressed at the same time Same went for my 6 RX480's, without tweaking them they'd pull 1200w+, after a bit of undervolting, 700 to 800w pulled From the wall figures

The Corsair HX1200I should satisfy your needs and it can be monitored and controlled in Windows too with a 10 year warranty.

Its like you skipped the other 57 posts...

Please share why you would make/suggest this user spend on a 1.2KW PSU when 850W is already plenty? What makes you spend over $100 more?

You are right I was just replying to the original post. The reason I would suggest that is because you (The OP) don't know what will be the computer be in 5+ years. I always get more than I need so that if I am upgrading to a more powerful PC I won't need to replace the PSU. I also like the accoutrements that come with high end PSUs.

Thank you for sharing those reasons. Please note you can buy a 'high-end' PSU with the accouterments and also be around the appropriate wattage for the build and future upgrades. High-end doesn't mean High wattage.

I believe the term you might be looking for or getting to is 'High Quality'

Not really, no. Maybe that is for Kapone, not me. I was simply springboarding off of his words.

 

[Tomgang]

What are we still arguing about PSU watt. I believe in the end that it's my decision to chose what wattage I want. No matter what I need and don't need right now, I am going for a 1000 watt PSU and that's final. I don't want to buy a to small PSU for future upgrades and will hate to have to get a bigger PSU later. This setup I hope will last 6-8 years and I don't know about example gpu wattage consumption will be or if sli will be more a thing again in the future, cause frankly I miss having two cards.

Also I might go for threadripper later or back to intel, if I find cpu or features on X570 is not to my liking.

It's alright to give sujestions, but I only asked for what fabricant I shut get and I have chosen Seasonic.

Thanks for all replies again.

Nobody ever said it wasn't. If you want 2 GPUs later on, for whatever reason (you have a single 24" monitor now...), then yeah, 1000W would be good. But those who suggested more just like spending other people's cash for no reason. Just trying to thwart the blind leading the blind as so often happens here.

Have fun with your new PSU...!!

 

[Zach_01]

At least some poeple, including me, while suggested the 1000W option, had added the word "if", a bunch of times... and it was for a reason. But that wattage alone is like red flag for others.
Was those (former) people the only that had understood the OP's mindset and will to future strategy/options? ...I wonder

Enjoy you new PC Tomgang

If SLI will be more popular and better supported again, then yes for sure I will have two cards again.

About monitor, yeah that old thing is also in for a replacement later next year. This upgrade I am about to do now, is not cheap and all my current savings goes to this. Monitor is probably gonna be replaced with the next gpu upgrade some time then nvidia release RTX 3000 series cards next year.

This asus monitor is in for consideration right now.

Sure I see your point about others waisting money on my or others behalf. Having fun with a psuhmm maybe not so much, but the hardware it's gonna power, yeah that I will have some great fun with oh and no more (glass ceiling) you like to call bottleneck.

Sure the "if" i get that.

Yeah for some it's clearly a red flag and they think I waisting my money with a to big a PSU. They just don't think about the reason behind it.

And yes a bigger PSU is to future prof for future upgrades and adding more power hungry hardware later like a Second card or maybe trying to go for LN2 oc.

It's not so often I get new hardware, so I will for sure have some fun with it. X58 has been great, but time has caught up on it so it's no longer providing everything I need fei. It.

1. It (SLI) won't be better supported again... so don't get your hopes up(?). The trend, for years now, is that it is going away. To plan for it today, for potential use next gen isn't a good plan, IMO.
2. That is a high Hz 2560x1440 monitor. A single 2080Ti will pound through that already. You will be on a single card for that res and refresh rate.

You could have easily used a 850W PSU and saved some jack. This is why we ask (some of us) probing questions or clarify other information.... to help the OP the best we can instead of just blurting out random overkill PSU wattage without knowing. But hey..... the avatar says it all.

Some people just dont get that other people are enthusiasts and prefer big watt PSUs, but feel the need to make a point which nobody even gives a **** about as if the opinion would matter now after you made your choice.

Btw, I think that Seasonic 10 year warranty is too short. Probably last plenty longer than that. Lol

 

[Zach_01]

SLI/Crossfire are pretty much dead already and looking hard to come back any time soon, if ever. Was definately not a point by me, I didnt speak of it ever. All my "ifs" was on other things.... Im not going to tell again, its all over previous posts.

About monitor, yeah that old thing is also in for a replacement later next year. This upgrade I am about to do now, is not cheap and all my current savings goes to this. Monitor is probably gonna be replaced with the next gpu upgrade some time then nvidia release RTX 3000 series cards next year.

Sticking with the standard form factor eh? I'm kind of set to wide, or maybe ultra wide.

 

[thesmokingman]

It won't and yer better off not getting your hopes up. When Mantle, Vulkan, and DX12 offered ideal access to hardware to game devs they balked that it actually required them to work to optimize for multi gpu.

Just get a titan like I did. Then you can stop wondering what if. Ironically the Titan XP has saved me from upgraditis cuz it was so OP for so long. It's still right up there at the top of the food chain 4 years later.

It has nothing to do with being an enthusiast, but you missed that trying to be snarky...we get it. What we dont get is buying massively oversized psus for BS reasons. OP's always do what they wish, our job is to inform them so they can make an educated decision.

But to say an enthusiast is justification for doing so is really short-sighted IMO.

Anyway, apologies.. I know I like to force feed information. Peace out.

 

[Zach_01]

How are you(plural in general and out of this thread) manage to turn most of threads in here about judging and criticizing and mocking other people... is amazing and frustrating all together...
Can we talk tech only stuff... pass our indivitual opinions/thoughts/experiences/knowlegde/info freely and stop calling names to each other? Can we respect other's opinions? And let the OPs make up their minds? Can we disproof false advice and misinfo only with facts and no characterization. Is this possible?

Is all this childish behaviour leading anywhere?
