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.
This article made me consider a FSP PSU for my next build.
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 stuff
980ti's ain't modern, they're two process nodes behind!
What's up with Hexus only reviewing very high end PSU's now days? Back to back to back.. I was under the impression that even high end we're no longer maxing out the PSU and actually focusing on efficiency and lowest power possible. This of course is designed for very high end rigs that take this sort of power and need it to be reliable at these levels, but average PC's, any chance of a review of any new PSU's out in such ranges of 400??
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.
But I agree that lower wattage PSU reviews would be very welcome - PCs are more efficient than ever these days.
Oops, I did not mean high end as in quality or makes, but high end as in wattage. Just to be clear.
A 600W PSU to me is kind of high wattage, but you're right, it seems just above average gaming rig levels, possibly on the sweet spot for some, but I think that more 400-500 PSU's should be ideal for gaming rigs, for example, look at this average/good build, if the estimated power consumption is correct, we're looking at max 450 possible draw, 81%. 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?
Is 81% meant to be some kind of standard over-provisioning thing?
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:
Computerbase had 246W (1080GTX reference) to 348W (Zotac 1080GTX Extreme) using an 4.5GHz ii-6700K system (which was hard to find as they no longer list it in the reviews instead referencing https://www.computerbase.de/2016-05/...stsystem-2016/).
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."
No I gave that actual percentage that I am assuming it is even using from the PSU at max, (assuming that's the realistic load would be with his actual power draw when gaming with the PSU he has in that build..) I never made any suggestions, I did not even look at his PSU's efficiency levels, just that he's only ever using 81% of that PSU.
Maybe I don't, I am not sure to be honest, feel free to correct me if I am, but my thinking is this: Efficiency is important, if you're too low or too high you might not be getting what you paid for and also if you're stressing out your PSU constantly due to buying a too low one you might end up wearing it out quicker. If it's having to work more to cool it down that's also extra noise and extra heat.
OK, don't think I contradict that, but I'm still learning with how PSU's work, so good to know.
