Coming out to play with the big boys.
No way would I ever spend that much on a psu!
Terrible efficiency at typical load levels though, this should only be used by people with extreme rigs.
If they'd let it turn the fan off at low load they could have saved on the cost of the fan motor, no-one would know the difference. It's literally impossible to get this thing to 50% capacity with modern consumer high end kit - an entire system with a modern titan X only takes 263W, peaking at 300W initially. Given the overheads involved for the CPU in that figure, a twin card SLI rig shouldn't get anywhere near 600W
Quad SLI is possible. Or even just Quad cards with doing compute work. But yeah, it's pretty niche.
Would be nice for a workstation rocking dual CPU's and quad GPU's etc. but this is definitely not for your average home PC haha!
Another piece of hardware to put on my "lottery win rig" list though!
This article made me consider a FSP PSU for my next build.
Literally impossible? Literally impossible??? Such ridiculousness can't go unchallenged (or unmocked)Quote:

Quad/tri SLI isn't supported in games any more, it only works in e-peen benchmarks. Anyone doing compute work ought to steer clear of 'gaming' branded tat, they'd get proper professional stuffQuote:

It depends what they get sent, but I think your comment about 'only reviewing very high end' is demonstrably false - the second-most recent PSU review they did was a SFF 600W unit from corsair, and the one before that was the budget range from Be Quiet.Quote:

Oops, I did not mean high end as in quality or makes, but high end as in wattage. Just to be clear.Quote:

His PSU (EVGA SuperNOVA G2 550W) is at 90% efficiency I assume.
That build list says, estimated 397W, where do you get the 450W from?Quote:

Or are you making the mistake we see over and over again about what efficiency means?
Let's make it easy and take a mythical 1000W supply which is 90% efficient.
This means the maximum DC it can supply is 1000W and it will draw 1111W AC from the wall doing so, wasting (as heat) 111W.
What it does NOT mean that that a 1000W supply can supply 900W DC while drawing 1000W AC while generating 100W of heat.
Sorry for the rant.
I would be surprised if that system even needed that much from the PSU. Hexus tested at the wall with a slightly more hungry system (OC'd 6700k) and got a load of 250, so would only *need* a supply rated 225W or so. But if wanting to keep at the most efficient range of around 50-70% while gaming you'd want a 400-450W supply. Or less if you wanted more efficiency when not gaming.
Certainly, that's about average:Quote:

Other places who only measure the card (nice to know and more trouble for them, why do they not also list system draw too?) got around a peak of around 180W to 200W for the card. Even more power hungry cards are hard to push past 300W. Hareware.fr managed to get their to Titan X Pascal at 299W although without their 'Uber' settings it was 212W:

As usual building guides seem to go crazy with recommended PSUs.
With my earlier reply I missed the rather important 'NOT' which rather lost the meaning :)
Well I got that figure from Gigabytes own recommendation for a PSU to run that graphics card, although but most realistically at it's max load, so realistically we're looking at 465 Watts when gaming? Or did I mix up "system power consumption" with them meaning the entire system or just the GPU on it's own, if so then yes my power consumption estimates are wrong.. 397W-180(taking out the estimated GPU as it's average, not possible max needed)+248(adding the hexus review GPU load)=465 to be roughly close. Also "Wattages are estimates only. Actual power draw may differ from listed values."Quote:

If it's having to work more to cool it down that's also extra noise and extra heat.Quote:
