If you are wondering the exact psu it is this one here: NEW 450 Watt 20/4-pin ATX PSU Power Supply SATA LED BLU - eBay (item 290447460717 end time Jul-21-10 15:07:06 PDT)
it may be crap, I'm not really sure. But it is enough to run my graphics card and that's all I wanted.
Which 8600 is your graphics card? An 8600 GTS wants a 450W power supply with at least 22A on the +12V line.
Th eBay special that you list is
crap. 17A on the +12V line is poor for a 450W supply. That's not much better than you'd do with an honest 300W
PSU (15A typical). There are a number of 400W supplies that offer rather more current, like this one: Newegg.com - Antec NEO ECO 400C 400W Continuous Power ATX12V 2.3 / EPS12V 80 PLUS Certified Active PFC Power Supply
(Antec Neo Eco 400C, 30A. $50 + $6 S&H.) You don't need a $200 PSU, but I wouldn't wish a generic supply like that on anyone.
PSUs are fairly easy to replace. They are usually held in with 4 screws at the rear of the case. The only question is whether there is room to remove it easily. In a tight system, it may be easiest to remove the PSU if you first remove the motherboard or optical drives.
