Will this PSU be enough for a Core 2 duo E6300?

A Core 2 Duo E6300, and probally with 1GB DDR2 533Mhtz, and a 7600GS

The PSU is a Thermaltake 420watt.

It should be, what is the amps on the +12v rail?

 

[K@in]

for that system, a 300w will do no problem

Hello,

Yes, it's enough, but for your assurance, buy a new PSU with a power of 550W.

With that system and a 420W PSU, you already have at least 40-50 Watts of upgrade headroom.
Putting wattage aside, what is the amperage on the +12V rail(s)? Consult the chart on the label at the side of the PSU.
