i was just wondering if any1 would be able to help me i have just bought most of the parts below and i wanted to make sure my 750w PSU will run this weekend.

current setup:
Window 7 ult 64bit
CPU = Intel i7 2600k
CPU Fan = NZXT Havik 140 CPU Cooler
Mobo = Asrock Z77 Extreme4
GFX Card = 2x EVGA GTX 680 SC Signature 2048MB in SLI
RAM = 16GB Mushkin Enhanced Blackline Frostbyte (4x4GB) 2133
SSD = Intel 520 Series 120GB
HDD = seagate 1tb
PSU = corsair Pro HX750w <------------------------------- PSU in question
Case = Xigmatek Utgard (this case has 3 fans in it already)
Monitors = 3x liyama E2407hds (i run these at 1920x1080)(5760x1080)

thanks for the replys

Should be absolutely fine. You could run that on a 650W PSU. A single 680 only needs about 200W, so two of them plus a 2600 would need around 500W.

Yes, 750W is enough.

He'd only need higher if hardcore overclocking is involved. Say 2600K at 4.8GHz or higher and GTX 680s that have been overvolted and average around 1250MHz with GPU Boost.

Should be fine, you have a good quality PSU there and the GTX 680's are very power efficient, which tend to use less than even AMD's counterpart - the HD7970.

ok ty all for the info if something goes wrong i will know what it is

I have an 850 watt in my computer, with a GTX 570 superclocked. I originally had a good quailty Thermaltake 750 watt. I had to get a 850 because some of my fans werent getting enough power and weren't comming on. Popped the 850 in there and everything ran smoothly.

This sounds incredibly unlikely. Cold cathodes and LEDs require very little power. Fans only need on average 1-2W at 12V. Most fans spin up at 5V, or less than 1W in most cases. If the fans are plugged into motherboard headers they are taking power from the 24-pin ATX connector. If that connector is having trouble supplying power to fans it most certainly wouldn't even turn your PC on to a usable state at all. If the fans were connected to molex connectors, then I my first guess would be those connectors/cables themselves were faulty and not the rest of the PSU.

Certain Thermaltake PSUs like the Toughpower Grand 750W and the Toughpower XT 775W are in the upper tier, among the better PSUs on the market.

Your main sources of power are going to be the following

GTX 680 up to 250W each with a mild OC
2600K up to 130W with a mild OC
Mainboard around 40W
HDD/ODD around 15-20W each during spin-up only.
SSD around 5W while active

Or your PSU was in some way faulty and the wattage had nothing to do with it.
