Antec quattro 850w PSU for 480 SLI - Page 5

post #41 of 54
Sorry to hijack, but I've been curious about this. Would an overclocked GPU with no voltage increase consume more energy than a card running at stock?

Of course, and overvolting exacerbates that.

I think you'd be fine. I SLi'd 480s with a 1055T@4 on an HX850 and never had a problem even with both cards at 900 core and 1.1v

that was my initial thought, however, it does seem that there are mixed views and i'm somewhat getting confused now. Only way to tell is to try it I supose.

Here a site that can help you out.

EDIT
I always add about another 100 watts to that to be on the safe side.

The problem with these power supply calculators (here is the original version of that one by the way) is that they are usually very inaccurate. They're sometimes ridiculously inaccurate, but it always depends on how the person uses it. So if they're used correctly, then they're relatively accurate. However, if they're not used correctly, then they can either provide results that are significantly more than the amount that's actually needed, or much less.

So when you recommend these calculators, you simultaneously become responsible for making sure that it's used correctly.

I hate using calculators lol, last time I checked for my rig, apparently it needs over 1kw. I don't trust PSU calculators.

It all depends on how you use it. I could help you use it correctly, but to be honest with you, it would be a waste of your time.

That one is the most accurate one that I find so far. My sig rig with oc cpu and everything else is at stock it says about 530 watts, which is about right.

EDIT
This is bare min.

Yeah, but it still depends on how it is used. I'm talking specifically about what settings you choose, especially for System Type, CPU Utilization, the accuracy of your overclock settings, System Load, and Capacitor Aging. However, I should be listing absolutely everything.
