So, I have an HX650. Nice modular Corsair PSU, +12V @54amps, and 80+ gold certified, 90% efficiency under load.
I have an FX-6300 at a moderate overclock (I always fear that I will "burn out" the CPU for some reason, also it keeps the fan nice and quiet) of 4.2Ghz @ 1.4125V.
My Sapphire 7870 XT graphics card is on stock voltage, overclocked to 1100MHz, 1600MHz memory, with a +7 board power draw (Trixx utility, I dunno exactly how it works). I'm not sure of the voltage, but according to a random bitcoin thing I was looking at it was 1.256V.
I plan to buy another one of those GPUs^.
Will the 650W be enough?
Would turning down the GPU OC help lower their power draw? I'm willing to lower some of their speeds since having two of them will no doubt bring me up to 60+ FPS on basically all games (I mean, with exceptions, like Witcher 2 ubersampling or unigine heaven).
My other question is, how can you tell when your power supply is not providing sufficient wattage? Will you get random shutdowns/bluescreens? CPU/GPU throttling? Is there any software to help you see where your power is going, and how much?
