Power Consuption

I'm running:

3570k Running at 4.4ghz with a Corsair H70 Cooling it.
gtx 670 Oc
3 hdds
1 ssd
1 dvd drive

I have a 650 watt corsair power supply. If i ever feel like adding another 670 for sli will I have to also upgrade my PSU?

650W will be able to run your system in sli, but it will be running close to capacity, so combined with the age of your psu, there's a chance that it will blow sooner or later. When your psu blows, it may damage the rest of your computer, and it will make a very loud sound that will hurt your ears. I would recommend getting a 750W-850W psu.

yes you would get something like the corsair tx 750 <-- bit overkill though but i don't think that the 650 version will be able to suffice or it will be right next to its breaking point

Okay thanks I assumed as much. Oh and yeah I know what its like for a PSU to go. My first ever homebuilt pc had a dodgy ocz 700w psu and smoke start pilling out of that thing right in the middle of a Starcraft 2 game!
