That's something like 40% more!!!!!!
My 750W seasonic prime has no issues dealing with both an overclocked threadripper and vega 56 running flat out. Top whack it draws around 600W, with everything running flat out folding. I had no issues with my 8 year old corsair tx650 whilst running threadripper with my old GTX780 either. I only went with the 750W supply as I wanted to move from bronze efficiency to platinum
No problems at all with my AX860.
Anecdotally there have been problems with some Corsair PSUs and Vega reported further upthread, but I don't know if it's a widespread problem or not.
DebatableIt's a scam, look at the clock speeds, they are completely different, something fishy
If the GPU is working harder, the clock speed will be lower on Vega. As the resolution increases, i get lower clock speeds. For example, in Doom i may get 1750Mhz at 2560x1440, but that drops to 1700Mhz at 4K.
By the looks of the graphics, it should be running at thousands of fps.
Seasonic Prime platinum 750W which has 62A available on the 12V rail. (744W) All fine here from stock right the way up to 1721MHz/1100MHz at the full 1200mV. That’s on a 56 running a 64 air bios.Can you guys that i have quoted tell me how many amps on your 12v do you have?
My choice for a new , new one is either a kolink 1000 bronze, or a gamemax 1050 gm silver.. But any one that can suggest under £100 for a 800+watt psu with 70 ish amp 12v rail would be great.
Vega is such a power hungry monster, nomnomnom

Wattmatt, been a while how are you sir.If the GPU is working harder, the clock speed will be lower on Vega. As the resolution increases, i get lower clock speeds. For example, in Doom i may get 1750Mhz at 2560x1440, but that drops to 1700Mhz at 4K.
Ok so after much researching it seeeeeems, like its the amount of amps, this psu only has 62 on a single rail, where as my last one that was fine had 72, as does @Vince

Don't think that's your problem. I ran my Vega 64 on a 650Watt PSU with only 54 amps and it ran perfectly.

Load Testing
Is that an iceberg on the horizon? Yes, yes it is, and the Corsair CX750 sails right into and then goes straight to a watery grave.
The Corsair CX750 is an entry level product from Corsair and, today, it performs a good bit below even those standards given that Corsair used to produce quality products from top to bottom. This unit’s current product placement is readily apparent from the outset as the build quality has issues, particularly noticeable since these are coming from a "name brand" and not a "no name" company. The 3 year warranty support is probably trying to tell us something as well. The unit is not very quiet, and the performance just falls flat as it can not complete testing.
What we have here today, for most of us enthusiasts, is a decent performing 650 watt unit with a 750 watt number on the side.
It may or may not be the supply, when the reviews on the CX750 say things such as:
Those quotes are both from Hard
And this from JohnnyGuru
Not exactly glowing reviews even if the JohnnyGuru review is quite a bit more positive than the H review. What made me think it could be the PSU was when told that overclocks cpu wise that were easily achievable on your old PSU aren't on this one, also your extra overheads in multiple water pumps, quite a few HDD's etc could be pushing this budget psu over the edge. On top of that, I have got to know you and I know that you love throwing everything and the kitchen sink at the card, running +50% power limit and pushing it hard.
Pushing my vega to the absolute max I see some of the biggest power draw figures in game lobby's etc and at +50% and the max overclocks my card will take I have seen it pulling around 400w.
Personally I run a Seasonic 860 Platinum with 70 odd amps on the 12v rail but that is also powering a 1950x, vega, rx570, rx560 and rx550. one things for sure I don't get random power off's like you seem to even if I leave 3 cards mining, 8 threads of 1950x mining while playing games on Vega. I dunno man but I would wack everything back to stock, see how stable you are then start pushing things if you feel you need to. You know what I am like stability trumps everything so I just find what works and stick with it.
No, it's perfectly normal. Lighter load, higher clock speeds.Wattmatt, been a while how are you sir.
Is there a way to combat this as obviously no one wants lower clock speeds?
And please if someone can still help with this amp / psu problem I have i would be so grateful im ordering one the second i find something decent, IF thats the problem.
If me I'd observe the hbm2 temp, the hotspot temp and the vrm/gpu core temps from hwinfo, put the stock bios back on, stock clocks on cpu and ram, stock clocks on gpu, and try and fault find from there.Absolute Legend.
So just for prudence sake, it is not the psu that is the problem as everything is set now to the same as was working perfectly before. What else could it be?
Yes, i changed to the 64 bios (non LC) and all my problems went away, was even much faster than the LC bios, absolute bliss for a few weeks and then the PSU said "sorry mate too much for me im old"If me I'd observe the hbm2 temp, the hotspot temp and the vrm/gpu core temps from hwinfo, put the stock bios back on, stock clocks on cpu and ram, stock clocks on gpu, and try and fault find from there.
What area you live, If local enough you could test on my system.
edit, did you not always have an overboosting and crash problem with the v64 bios?

New sea of thieves sees VEGA gain a massive performance boost.
