Should I downgrade my PSU?

[vromanowski]

When I built my PC I was planning on running tri-SLI, so I bought this awesome Tagan BZ series 1100w. Well, 2 years later and I've gotten rid of those video cards and now I'm only running a single GTX 480.

Thus my current PSU is definitely overkill. Though it's 80 plus I know I could put in a 600-700watt 80 plus Corsair and my electric bill should go down, but how much?? Would it be worth downgrading? What do you guys think?

Leave it as is. You are right about the overkill.

The computer will draw just the power it needs. Changing over to a smaller PSU will not lower your electric bill significantly.

It wont make much of a difference, the PSU only pulls as much as it needs and if its 80+ that means its already reasonably efficient, swapping out for a smaller unit will boost your efficiency some at low loads but i wouldnt expect a significant drop in your electric bills, certainly not enough to pay for the difference in efficiency within a reasonable time frame.

Damn, OK. Thank you.
