How to choose a good PS for gaming?

[EQTitan]

As the topic states how do you figure out what is a good PS strictly based of the little Voltage/Amperage chart?

Well some more info on your rig would be helpful. Personally I would look at Fortron or Seasonic for a PSU>

You don't. The cheapest/lowest quality PSU's are known for exagerating their amps and also you'll often see larger voltage fluctuations on the different lines, specially under load.

Well my specific machine has the following but I was generally speaking. Is there a good way to determine which PS is needed for SETUPa - SETUPz?

Gigabyte K8NS Pro
AMD 2800+ 1.8ghz
EVGA 6600 GT 128 AGP
2x 512mb Consair DDR400 PC3200 2.5-3-3-7
WD 120Gb HDD PATA
WD 12Gb HDD PATA
NEC 3510a
Lite-On DVDR

A good brand 300W PSU will easily handle it, 400W to be on the safe side specially if the PSU is of lower quality. For a modern computer you need to have as high amp rating as possible on the 12V line as that's the only one that will be stressed as most components draw from that.

I'd go with a Fortron AX400-PN/AX450-PN, judging from your system. Depends on what system you want to buy in the future, though.

Like ^^^ said, quality 300W will handle it easily. That would struggle with a much more more vid card so 400W recommended for anything up to and including the 7800GTX. If you imagine running the X1900XT in the future a 500W is probably wise tbh.
