Is 18 A enough for my PC?

[sanchz]

I've got a 450 watt PSU (between generic and brand PSU), with 18 A rating on the 12v line.
My system is:
Asus M3A 770 chipset
Amd Athlon X2 5200+ (65w TDP)
Geforce 8600 GT
4x1gb DDR2 800 MHz RAM (4 sticks)
500 GB Sata II Seagate 7200.11 HDD
180 GB IDE Seagate HDD
DVD-RW/+RW Optical IDE Drive
5 80mm Case fans
Is the PSU OK?

It's fine for your current system.

Yes, 18 amps is plenty for your current system.

The 8600GT video is a budget card that draws only 50 watts and 4 amps at full load. The rest of your system does not use very much power either.

The 12 volt rail is only responsible for hard drives, video cards, and optical drives, and RAM. With an 8500gt 18 amps is a-okay.

And CPU's.

The RAM is powered by the 3.3 volt output.
