Thinking of upgrading my 580 1.5GB to 760GTX 4GB, mostly to use with XPlane 10. I'm a little worried about power though, as the 760 has two fans while my 580 has one. My power supply is only 720W - is that going to cause a problem?

720 Watt Power supply should be perfectly fine. I still rung my rig on a 500 watt PSU(and, yes, before you say it, it is VERY LOW, but I've never had problems, and I hope I won't).

Here, you can check your system's power requirements yourself:

These online power calculators are just a rough approximation, so if your calculated power demand is close to your PSU rating, you might be a little concerned.

 

Personally, without knowing the rest of your hardware, you should be fine with that PSU, though.

I think you will find that even an overclocked GTX760 will use LESS power than a standard GTX580.

 

gb.

Thanks for the feedback gents. Think I'll go ahead and order this.
