Is 18a on the 12v rail sufficient for overclocking?

Question

Athlon 64 3700+ 939 (2.2 mhz)
Biostar TForce 6100-939
2x512 Crucial Ballistix
DVD Burner
160 gb hard drive
3 80mm case fans w/ led, 1 120mm w/o led

SunBeam 480 watt:
+3.3@28A,+5V@34A,+12@18A,-12V@0.8A,-5@0.5A,+5VSB@2A

Using hardware doctor, it states 12v: 12.1

Answer 1

Hi. Overclocking rarely uses enough current to create too much of a load on a good PSU. You may have to raise the voltage a bit but be careful. My system is liquid cooled so the temps do not get above 50' F. You will also need to make sure your CPU keeps cool. (Four fans in the case will certainly help.)
