12700k PSU

[wisnoskij]

Hello,

Been looking over the PSU list and looking them up on pcpartpicker, but am a little confused on how I should be reading this list.

How does a a PSU get on a A tier, get a golden (best in class) name, but have a note next to its name saying that if you plug this PSU into a graphics card it might randomly trip all the time? Should I just focus on the golden names and more or less ignore the notes as they are only talking about a tiny tiny chance that the manufacturer would make right for free anyways?

I was originally looking for a Seasonic since I heard such good things on the WAN show, but this forum does not seem to give them any special reverence.
Looking for a PSU for a 12700K build. I would pair that with a 3070-3070ti if I could buy one at msrp but who knows that I will end up with.
Was looking at 850W, that is most likely good enough and seems to be a good spot in value per watt.

id go with a corsair rm850x or higher

Also does 'Whisper M =>650W' 
Whisper M's that are greater then or equal to 650W? 

And does 'AXi (<=1500W / 1600W)' mean that the 1600W AXi is a (golden) great PSU, but the 1500w and less are not as good?

By higher you mean, Go with a corsair rmx, but consider more watts?

Thank you so much.

It depends if you are upgrading your stuff soon, as 4000 series cards might require lots of power but 850 is enough if you were gonna get like a 3080 maybe a 3090 and a 12900k

Because it's the GPU's fault. The PSU did not have problems before.

[wisnoskij]

Great thank you. I think I will go with that.
Based on what I heave heard about the 4000 series, even a 1000watt might not be enough, and the PSUs cost WAY more per WATT in that range, so I would just get a second PSU at that point.

Considering the list of GPUs that cause this is just the list if the highest tier, highest draw GPUs, are you not just saying that before when we only used the PSUs at 20% capacities we had no trouble, but when we tried to use them for their stated power draw they failed?

Like even the Gigabyte GP-P750GM will function fine until you try to use it for its advertised wattage.

I am not trying to be sassy, and know very little about PSUs, but how can we blame both Nvidia and AMD and claim that all of their highest grade most expensive GPUs are faulty and it is the 1 brand of PSU that cannot handle them that is the victim here?

12700k needs 300W on its own - it doesn't consume as much, but that's a healthy margin to have. A higher end GPU of today will need 300+ watts. That already qualifies for an 850W PSU to avoid overcurrent protection at power spikes. In a year or two, it'll be normal for a GPU to suck upwards of 400W, which means that 850W will just about suffice with little headroom, or not even, when you consider other components such as water pumps, ram, ssds, fans, mobo chipset, power losses... If you plan on going big on GPUs in the future, I'd actually get a 1000W. As ridiculous as it sounds.

Thing is computers today do not draw power like a searchlight or massive air conditioning system, their current draw goes up and down in a wave that cycles in the MHz or even GHz range. When I say I blame the GPUs, I blame the ever increasing difference between peaks and lows which leads to different environment for the PSU even if you keep the average power draw the same. This is never as simple as what they say or advertise openly which are average power and recommend PSU wattage.

 

This is not a strict violation of the GPUs because ATX12V did not pose limit in transient caused by electronics. However you can't expect PSU designers and makers to overengineer their products enough to be good with something else in the future that they have no information on either. In the world of computing though we do have an unwritten rule that newcomers should try work with the old ones as much as possible. Support of old instructions in CPUs or old functions in programming languages for example, a lot of them aren't used by programmers today anymore but x86 or the language is too widespread to eliminate support for them from the CPUs entirely without breaking somewhere someone's software. So here they stuck, wasting space on silicon wafters and your SSD/HDD. This is why I think the blame goes to the GPUs.

 

Of course today's world is a game of capital. Guess what's not going to sell when a PSU doesn't work with a graphics card? That's why it's Seasonic fixing their stuff, not Nvidia/AMD detuning their GPUs and increase soaking of transients on graphics card PCB designs.

The sale ran out.
I went through all the A-tier golden PSUs. How about a Whisper M 80 Plus Gold 850W (BP-WG850UMAG-7FM) my local stores have them on clearance. The one thing that worries me is the specs call the graphic card connectors "PCI-e 2.0 connectors" (is this a 15 yo design?). Their seem to be six 2+6 pin connectors, and I assume these are the same 8 pin connections that modern graphics cards take. So it seems to have anything I would need, but am surprised the PSU technology has not really changed for so long. Is their any benefit to more modern PSUs?

Nothing to worrie about. PCI-e connectors didn't change for over 15 years. The internals of the PSUs changed a lot. Whisper M is a modern high-end PSU.

That's because Linus fanboys the hell out of them, and they're also a regular sponsor.
