Hi chaps,
I bit the bullet and popped out lunchtime and got a new 650w PSU which I'll fit this evening. I just haven't got the funds to go for a bigger one right now. My rig is far from state-of-the-art so I think that a 650w will hopefully suffice although your point is a good one Jim. Either way it is a start to putting things right, I worked out very roughly that my PC does at the very least 40-50 hours a week and over four years that 8,000-10,000 plus hours so the poor old chap/chapesse (very PC "politically correct" there)

could do with a well earned retirement so that it can see out its twilight years in the "
Sunnyside Rest and Retirement Home for Senior PSUs" AKA my collection of knackered and/or obsolescent PC components, past and present
Cheers
Leigh
