How important is PSU efficiency?

[donuts]

I've got a few psu's I'm using, but they're getting a little age on them. (Sparkle 550's) They seem to be running strong. I will be replacing them, eventually.

Should I be moving this up the priority list because of age and efficiency? Or run them until they start giving me problems.

Sorry if this has been covered already.

As long as they work and are stable then they do not need a lot of priority. I wouldnt wait forever though.

i'm a big fan of high efficiency PSU's...my power bill is high enough already.

Dito, that's what I got the Akasa PowerMax 850W .. it pulls just under 1000W which is pretty dam good for an 850W PSU ..

More newer efficient psu are quiet if that is a desired feature.

Efficiency is high on my list. FSP PSU in my sig is 80% efficient I believe.
