How much power do I really need?  

post #1 of 117
Thread Starter 
My Power Supply Died yesterday. May it rest in peace. Now I'm in the market to buy a new one. The one that died I think was way overkill. 1100 watts "see sig rig" My question is How much power do I really need to power my setup?

For the way your sig rig is right now, any quality 550-650W power supply is enough. I stress "quality". So I'm not saying that any 550W or 650 unit will be enough, but that any "quality" unit will be.

I would suggest 750w. You could probably get away with 650w. The one I linked is one of the best 750w PSU on the market. I love it and it's modular.

EDIT: You could also listen to the guy above me who probably knows a bit more.

Way overkill. I would get something like a SeaSonic X series or an S12IID in the appropriate wattage range for your system. If you plan on upgrading that GPU soon, you may want to think about the X650, it's my favorite PSU I've ever had.

Oh wait, you have two GTX 260s in SLI. For some reason, I missed "sli".

I change what I said to be any quality 550W or 650W unit.

The AX750 is the SeaSonic X-750.

Not way overkill. I was only 1 step above you guys.

650w/750w. You guys are on 550w/650w. Way overkill would be 1000w.

I missed the SLI part too... it's lower case, didn't pay attention.
