Solid choice, too. Either this or the Seasonic Focus GX 750. They will both work great with your AM5 project.

 

[dirtyferret]

consequently it is rare if not outright impossible to find good/decent bronze rated ones.

XPG pylon / corsair CX-M. basically the same units

after all, there's no reason to not certify your psu for the highest tier it can reach

Corsair rated their Vengeance series Silver for marketing reasons even though they did gold

Don't skimp on power supply.

Sorry for the below book but note I am responding to 4 different posters' comments.

Man with all this talking i don't know what to do , by the way i decided to , im starting to think a 650w bronze will be enough for me , im, not using premium GPU.

Right now i have a intel 2600k + 6650 xt , but im upgrading next month for am5 + ddr 5 + the new 9000 cpus.

Go by what you expect to have in the next 2 to 3 years. But don't guess. Calculate your needs. How?

The right way to determine the proper size needed is to research all the components, determine their maximum power demand, add them all up, and that is the minimum supply you should get. But that takes a lot of time and work. So I recommend using a good PSU calculator and the best and only one I use and recommend is the eXtreme OuterVision PSU Calculator. This will calculate your minimum needs and recommend a suitable size for those needs.

Plug in all your current or planned new components. Be sure to plan ahead and include all the hardware you think you might add in 2 or 3 years (extra drives, bigger or second video card, more RAM, etc.).

I recommend setting CPU utilization to 100% and Computer Utilization Time to 16 hours per day. These settings will help compensate for component aging, and add a little (but not too much) extra padding to the results. Having a little bigger than you need will typically also result in a little cooler and quieter operation.

Note that no calculator wants to recommend a PSU that is underpowered so they all pad the results, some more than others. The eXtreme OuterVision calculator is and can be the most conservative (which is why I like it best) for 2 main reasons. (1) They have a team of researchers on staff constantly researching components for us to keep their extensive databases accurate and current. And (2), it is the most flexible and has the most extensive databases of available options you can enter. This allows it to factor in all possible components to accurately calculate our needs, rather than guess.

Not knowing most of your current components, I plugged in 2 hard drives, 2 sticks of DDR4, and 3 x 140mm fans. The 6650 is not listed so I used the similar 6600 XT. As seen here, you currently could easily get by with a decent 500 - 550W supply today. If not sure what you will be getting in the near future, a quality 650W supply will give you plenty of headroom for most future upgrades. Just remember the graphics solution is often the biggest power hog.

there's a certain relation between a PSU's 80plus rating and its quality

Yes, but it is not a given. That is, the 80 PLUS certification program does not have higher standards for various specs depending on the certification level, except for efficiency. As I noted above, there is nothing in the 80 PLUS criteria dictating that Platinum will have better regulation or ripple suppression, as examples, than Gold.

But as I also noted, and to your point, better efficiency tends to need a better design - as in engineering design. But again, that does not mean higher quality caps, coils or construction techniques will be used.

(note: 80plus gold certification does not necessarily automatically mean a given psu's also of good quality. these days you can [without too much cheating] make your gutless wonders hit 80plus gold)

Right, only that applies to all the levels, not just Gold. A little more effort may be required for the higher levels, but as I just noted above, that does not insure the best parts or construction techniques will be used. One area cheaper PSUs may use shortcuts is in the internal heatsinks. A cheap, lower quality Platinum may use a smaller heatsink then couple it with a lower quality, faster spinning and noisier fan.

Cheating is a problem - but those issues can be mitigated by the potential buyer doing their homework before buying. Review sites like TPU will rout out those cheaters by noting where they fail to meet 80 PLUS, ATX and other required criteria.

This doesn't mean they need to upgrade their PSUs as often.

Exactly my point! With proper planning during the initial build/planning phase to ensure one gets a PSU that has the capacity today, with enough headroom for potential upgrades in the future, a good PSU will last well into the future beyond the point the rest of the computer is upgraded due to new technologies.

Again, I am not criticizing the 80 PLUS program. And while admit there are some deficiencies as dirtyferret pointed out here, the program was never intended to be all inclusive, and does not pretend to be. I will address a couple of his points.

1. As seen here, specific test equipment is listed. And, as seen here, testing will be in compliance with,

Annex B of IEEE 1515-2000, IEEE Recommended Practice for Electronic Power Subsystems: Parameter Definitions, Test Conditions, and Test Methods, for guidelines for general test practices and to section 4, Annex B and D of IEC 62301, Ed. 1.0, Measurement of Standby Power, for a discussion on evaluating measurement uncertainty.

By requiring labs to use the same IEEE testing criteria, this [hopefully] ensures all testing is done on a level playing field, regardless the actual test equipment used by that lab.

2. There have been reports of fake/counterfeit logos being printed on supplies and their packaging. Not sure what ChearResult can do about that as they have no jurisdiction or authority in any country to enforce the law. And the resources required to chase those offenders down would be astronomical. The best they can do is list the supplies that have legitimately earned the logo, as they did here. I note there currently are over 9000 supplies listed!

The bigger problem I see is the cost manufacturers must pay to have their PSUs tested and certified is typically $6,500 for the standard 115V and 230V EU internal ATX supply. That is a lot of money, especially for small companies just starting out.

Oh, BTW, all supplies are tested at 0, 5, 10, 20, 50 and 100% of rated load of the power supply. But the "published" results are for 20, 50 and 100% only (except for Titanium which includes 10% too).

So once again, it boils down to we, the consumer, doing our homework before spending our money.

 

[Dr. Dro]

When 650W is enough, overprovision to 750 for a safe experience especially if you intend to keep the supply for a long time. This will help account for transient spikes and also capacitor aging over time.

 

[dirtyferret]

750 for a safe experience

safe experience? Does a 750w unit come with protection a 650w lacks?

capacitor aging over time.

even mediocre caps on a mediocre PSU will take years past the PSU warranty to have an impact from "aging". Good solid caps will take will easily cover the 10yr warranty on quality PSU before they begin to be impacted by "age"; really it's hours in use, at specific demand and at what temp.

Transient spikes can take a PSU that's operating near its maximum capacity down, especially on more budget-oriented models. And... I'm not entirely sure on that second one. It will depend on the quality of the caps but also on the operating conditions. When it comes to a power supply, it is best not to skimp, because it's the one component that directly affects everything else on your computer. Your PC is only as reliable as the power being provided to it.

 

[dirtyferret]

Transient spikes can take a PSU that's operating near its maximum capacity down

if a spike creates an excessive power draw the OCP will be triggered, the PSU will work properly (shut down) and will be safe. Now you can make an argument if the end user choose a poor power supply and needed more power to handle their power needs but just because a 650w unit can't provide the power needed does not make that unit unsafe.

specially on more budget-oriented models.

yeah but you fail to mention you are now changing the quality of units, your exact words "When 650W is enough, overprovision to 750 for a safe experience". That is 100% incorrect as you can have a 550w unit with proper working safety feature and a 850w that's a ticking time bomb with little to no proper working safety features. And before you back track again and say that's not what I meant I will remind you to look at exactly what you typed as you said nothing about the units but their labeled power delivery by the brand.

Solid choice, too. Either this or the Seasonic Focus GX 750. They will both work great with your AM5 project.

the only thing the RMe has over the RM (budget unit you called it I think?) is the ATX 3.0 standard cable. Otherwise it's cheaper caps and a smaller fan from a lower tier OEM. It's a budget cut version of the RM line just with the new standard and I would say Corsair agrees with me since they lowered the warranty from 10years on the RM to 7 years on the RMe. Better off with the excellent RMx line.

 

[doomexpt]

OK guys , these are my options.

ATX Seasonic G12 GC Series 750W 80 Plus Gold = 90 euros
ATX Corsair RM650 650W 80 Plus Gold Full Modular this one its at 87 euro
Seasonic Fonte de alimentação Focus GX750 750W - 105€

Those are not atx 3.0


Corsair RM750e on promotion at 115€ atx 3.0 plus pci 5.0


Im 100% using AM5 board , ddr5 , if the new cpus are not good price / performance i will probalb ybuy the 5800x3d , i wont change my gpu any time soon ( 6650 xt ).

 

[nomdeplume]

I recently bought a 750w Gold Super Flower they didn't create a revision to meet ATX 3.x certification for. I have no regrets passing over that GPU specific cable slot or any other changes. Seasonic made PSU were specifically avoided despite having no problems with the Seasonic this was replacing.

Put aside all the marketing data and take practical consideration which of your selected options appeals to you the most. Just make fully sure you shop somewhere that makes immediate returns easy as well as buying from a company that fully supports warranty claims in your region. Don't overthink it. Do be mindful of any issues that you can predict with cable lengths or other considerations.

 

[dirtyferret]

ATX Seasonic G12 GC Series 750W 80 Plus Gold - solid but not made by seasonic with some cost cutting
ATX Corsair RM650 650W 80 Plus Gold Full Modula - also pretty good unit but some cost cuts probably not noticeable to most people
Seasonic GX 750w - there is a ATX3.0 version of this unit but I'll assume this is not it. Still an excellent unit

Corsair RM750e - further cut down of the RM line but does offer ATX 3.0

Really you need to find out if you plan on having a GPU that needs a 12VHPWR and and it's transient needs. The focus GX 750 can handle the needs of most mid level cards out there currently and like I said there is an ATX 3.0 version of it. Assuming you have moderate power needs, it would be my pick and the ATX 3.0 version the no brainer pick for most GPUs on the market. Otherwise I'd take the RM650 which can handle cards like the RTX 4060ti or similar.

Sure, OCP kicks in resulting in an emergency shutdown, there goes your data. Safety is more than just things not going kaboom

Second point, it may have been a blanket statement but it's somewhat obvious that a high quality 550W unit is better than a junk 750, however within the same platform you'll should generally try to get the largest supply you can afford to. that's what reviews are for, man.

Third point, I called the MSI and the CX budget units, OP edited the post with more choices later.

that's where you are wrong, safety is preventing damage to hardware
[/QUOTE]

Second point, it may have been a blanket statement but it's somewhat obvious that a high quality 550W unit is better than a junk 750,

obvious to you know that I educated you on some basics of PSU (no need to thank me) but i if it was obvious why post another incorrect opinion on PSU

however within the same platform you'll should generally try to get the largest supply you can afford to. that's what reviews are for, man.

also incorrect, jus because someone can afford a 1000w unit does not mean they will ever need it. Anyone should get the unit that fulfills their need of performance for the timeline they need it

Third point, I called the MSI and the CX budget units, OP edited the post with more choices later.

if the OP ninja edited then I apologize

 

[Dr. Dro]

Looks like we have different philosophies when it comes to this. A computer without reliability or the ability to retain data integrity is no good. A good power supply is like RAM, it's better to have it and not need it than not have it in the off-chance that you do need it.

 

[dirtyferret]

Looks like we have different philosophies when it comes to this.

it's not a philosophy, it's a basic failure on your part to understand the meaning of a word safety.

 

[Sunny and 75]

Think im gonna close my eyes and order

Thought you got that RM750e on the way.

OK guys , these are my options.

None of them provide a dedicated 12VHPWR PCIe GEN5 port on the PSU itself.

Take a look at these ones as well:

be quiet! Pure Power 12 M 750W (has got the dedicated GEN5 port rated at 600W)
Seasonic Focus GX 750W ATX 3.0 (the one with the dedicated GEN5 port)

6650 xt

Your current GPU won't be needing the 12VHPWR GEN5 port, however, upcoming RDNA4 ones might though.

 

[ExcuseMeWtf]

it's not a philosophy, it's a basic failure on your part to understand the meaning of a word safety.

Is it though? Data integrity also is an aspect of safety. Not just a straight hardware failure or lack thereof.

 

[Dr. Dro]

it's not a philosophy, it's a basic failure on your part to understand the meaning of a word safety.

At this point we're just bickering, to me, safety is more than just preventing things from going kaboom, it is also ensuring reliable operation of your machine. Your computer cannot work without electricity, and this electricity is sourced from the power supply. If your power supply's unreliable junk that shuts down when your computer is under heavy load, the data contained within your computer is not safe, because you are going to lose it and things will get corrupted the moment your machine undergoes an emergency shutdown.

Even if OCP triggers correctly and no harm is done to any of your components,, you still lost something, therefore, it is unsafe to operate your computer in these conditions until you either:

a) reduce its power footprint by intentionally reducing operating frequencies and thus its performance
b) install a power supply unit that can handle the workload safely

There's no way around this. This isn't even up for debate, it's more of a practical outlook at things: your computer's single purpose is to process data, and if it cannot do that without failure, then it's not worth anything.

 

[DaemonForce]

If your power supply's unreliable junk that shuts down when your computer is under heavy load, the data contained within your computer is not safe, because you are going to lose it and things will get corrupted the moment your machine undergoes an emergency shutdown.

Not philosophy but this is the exact type of situation that I had with my Pentium 4 box lunching power supplies at random. 420W, 460W, 550W, 600W, 700W...All in the span of 5 years.
Look, sometimes the power supplies are poor quality and they die instantly or way sooner than necessary. I get it.
Sometimes, the problem is the system you're powering with bad mainboard caps or a CPU so garbage that it gets dunked on by a historic AMD shitpost.
That was exactly 20 years ago. You know what has changed since then? I stopped running the Pentium 4 and moved on to significantly better equipped (and more power hungry) loadouts.
I also stopped lunching the power supplies. So sometimes it's best to write off an entire system as an unfixable failure.

The philosophy insert is that emergency shutdowns are dangerous to data so why not offload the data containers to a low power 24/7 system that doesn't get rebooted so often or run hot?
I moved my 4.9TB and 16TB volumes to the Athlon 64 (eMachines) box and this has been a much better solution for everything involved.
Is it an unbearably slow computer?
Easily.

That's my favorite part too because outside of maxxing out 10GbE SFP requests, it literally doesn't matter for what I need.
My local volumes are low power low capacity high speed SSDs at a good price and for BIG storage I just network this box to the server with the HDDs.
Safely. That's GG.

 

[dirtyferret]

safety is more than just preventing things from going kaboom

see you are wrong again, there is no debate. You are 100% wrong, sure you are allowed to have an opinion but its factually wrong as have actually been the vast majority of your opinions here in this thread. Your lack of PSU knowledge is actually disturbing since you are attempting to give people advice on a subject you really know nothing about and that is 100% dangerous and by definition an issue of safety.

Huh? I'd like to know where is my disturbingly awful advice but, looks like the folks in the thread seem to be in agreement with me. Oh well.

I've seen nowhere suggesting a hazardous suggestion by @Dr. Dro. He didn't bring the electrical protections earlier, ok. If they trigger and the PSU trips, that's great from a electrical (and quite possibly physical) safety standpoint.
Newsflash, the safety word doesn't only apply to physical integrity. Data integrity is very much a safety matter, unless you're gonna be pedantic and say the correct word for that would be security.

 

[dirtyferret]

newsflash! You just contradicted your former statement with your latter. If you confuse security with safety (or in this case simply overhead because the user in this situation fails to understand their current and/or future power needs) you should not be giving advice. Thank you, end of discussion

looks like the folks in the thread seem to be in agreement with me.

doesn't make you right as you friend just proved above (unwillingly but accurately)

from Seasonic themselves for the GX750 model. Not one mention of an extra 100w vs the 650w version making the unit safer in their "Protection" or 'Safety" listings
