£40-45 if you are lucky.
You can get a brand new Coolermaster 600W - 85% Efficiency for £62 brand new.
Seriusly guys pc parts just do not hold their value anymore,annoying i know
Electronics.. you'll have to look into half the new value (about-ish) its used, not to mention by the time you leave the shop the value already dropped.
at least, I wouldnt pay more than half the new price, jsut not worth the effort then.
The problem with the 520HX is that its over priced to start with. Most of the time you can get there 750TX for the same price.
See what I mean.
