Is a CORSAIR CX Series CX750 750W good for a gtx 660?

Is a corsair CX series cx750 good enough for these specs?

CPU: i7 4770k Have had problems with heat before

GPU: PNY GTX 660

PSU: Thermaltake 600W 

SSD: 64GB Sandisk

Mobo: Gigabyte Mobo

RAM: Corsair Vengance 8gb


It should be fine it says on newegg that its sli/crossfire ready so it should be good for one graphics card. If you go to pcpartpicker.com and plug in all the parts you have on the right side it tells you the wattage that you would need to run the setup.

You could have SLI on those 660s and be fine.

350 W PSU is enough to run a system with one GTX 660. 

are you mad?

And 450W is enough to run Titan.

You have a problem with actual power consumption of modern PCs?

Gaming community tends to greatly overestimate required PSU wattage. Don't think that I actually recommend doing this without a reason but it will work and can be useful when you want to make a system in a small form-factor where available PSUs don't have much wattage.

you sir go and put a titan into a system which is high end and power it with Vx450w 

Simple answer is YES, either of those power supplies will work perfectly fine. One of the main things to look at when purchasing a power supply is the +12V Rail Amps compared to what your card is asking for for the GPU,

of course other factors will come in to play as well but in reality you would have to have an absurd amount of equipment in your pc to need a bigger unit then a 750.

Titans have a 6 pin and 8 pin connector, that's up to 150W for the 8 pin, and 75W from the 6 pin, so 225W total ower draw max, adding 120W for a CPU, and 30Wish for HDD/SSD/ODD, and you aren't going to pull more than 360/370W, with an overestimated CPU powerdraw, which with modern CPUs, would be with an aggressive OC.

dont forget about amp's u will not find a 450 watt psu with 42 amp on 12v rail
