What kind of PSU should I get & can I even run it?

I'm planning a new build.
Intel 980X
Single GTX580 (adding a second later)
2 1.5TB WD 7200RPM drives (possibly adding 2 more later)
1 crucial SSD

I looked through the forums to see what kind of PSU I should get, the guide leads me to think I would need a 850Watt. However the guide doesn't have info for the GTX580 yet. My question is would I be better off with a 850 or something 1K+? Also I live in an old house and using a 1500Watt space heater throws my breaker, will I even be able to use PSU's this hungry?

Any help is greatly appreciated

If your system is powering down on a daily basis due to tripped breakers, I would spend an extra $100 for a ups battery back up device. Newegg has several models. For the power supply, they have a seasonic 850HT for $119.99 plus shipping that should be more than adequate.

My current system runs fine, however it runs on a 650Watt power supply.

The GTX580's power requirements are directly between those of the GTX470 and the GTX480. Nvidia made some power improvements.

One note: Your PSU wattage rating is irrelivant. What matters is how much power the system will draw. See here:

As for your home setup with tripping breakers, I recommend having your computer on a dedicated one if you are having issues. The only issue is that you will have to play around with switching breakers on and off to see which are connected to which power outlets. Once you find this out though, you could even set up your electrical equipment so that is is spread across the breakers.

Thank you for the info on the house power, it was very helpful. Do you think I should go with a 850Watt PSU?

if you plan to run the GTX 580 in SLI then yes. a 850w unit from enermax, silverstone, corssair, antec, xfx, seasonic will have plenty of power for you.
