Not enough power?

I recently watercooled my machine and have been pushing the overclocks on my video cards quite high. I'm reaching a wall of performance, and while it could be the cards just reaching their limit, I'm starting to wonder if maybe my PSU just can't handle it.

I have a Corsair 850 watt and I'm running the machine in my sig.

I used the antec psu calculator here:
http://www.antec.outervision.com/PSUEngine
and came up with 964 watts without overclocks.
Generally I think this calculator likes to over estimate, so I'm looking for some suggestions from other sources 🙂

So I'm curious, is 850 watts not enough for my system?
I'm not thinking about replacing it just to overclock higher, but when my next system upgrade comes around I made add PSU upgrade to the list

Without knowing what you're running, there's no way for anybody but you to get the numbers from outervision.

You also don't state if outervision numbers is minimum or recommended.

If it's minimum, then yeah, you might be insane for installing all that shit into a single case. You obviously are not married.

By what I'm running do you mean software? Software is gaming and distributed computing projects. The distributing project loads up both cards 100% with powertune +20%

And by hardware in sig, I'm not putting ALL the hardware in my sig in one computer, that would be insane. I'm just talking about the MAIN rig, not the other 2 crunchers.

Um. Yeah. OK, you're using about 504W then. So. Ok. Yeah. You're fine. Um. Bye.
 
964W with that kind of specs? I doubt that calculator is correct ever. That 850W should still be good enough for what you have inside your rig even with overclocks. Best way to measure is to get one of those Kill A Watt device to measure your actual power consumption based on efficiency and power draw from the wall.
