Power supply recommendations

[kingworldss]

I am having issues with my PC now, I think the culprit is my PSU so I need a replacement.

This is my system:

Videocard: Sapphire X1800XT 256MB
Processor: AMD Athlon 64 X2 4200+
Mainboard: Asus M2N-E AM2 nForce 570 Ultra
Memory: DDR2 800 2x512MB Corsair XMS2
Soundcard: Audigy 2 ZS & Sennheiser HD 212 DJ
PSU: COOLMAX 500W +12V1 18A

Soon I will be adding another 2GB of the same memory.

I am thinking about getting these two PSU, please tell me what you think of them or if I can get a better deal:

I have a PC power & cooling (OCZ bought them out I think) silencer 750W

Got it for $150. Highly recommend it.

Don't cheap out on your PS.

Those two PSU's are both in the same power and price range as your links, but better quality.

The Silverstone Zeus line is comprised of server-class power supplies, you won't find better quality anywhere.

The Corsair one is quite good too, also modular, and quiet.
