I'm pretty sure I'm safe, but...

post #1 of 9
Thread Starter 
Hey guys, I'm pretty sure I'm good in the wattage department, but I want to make sure I have enough headroom for overclocks.

I'm currently running an i7 2700K OC'd to a subtle 4GHz and my Samsung "magic" Green RAM is OC'd to 1866 with 9-9-9-22 timings. Not impressive, but I've just been playing around with the clock speeds. Sorry, I don't have the voltages that they are set at in front of me right now. However, I'm going to be dropping in a MSI R7950 that is using the 7970 PCB with the 6 & 8 pin pci-e power connectors. I know that graphics cards can pull a good bit of power under load and at an overclock.

How much am I going to be straining my 600W PSU if I overclock my card a good bit?

350w system there with overclocks, 600w is more than enough.

You should be good to go with your system. If you want to have some facts, maybe someone can lend you a kill-a-watt so you can see for yourself what your system draws from the wall.
