I would like to get a new seasonic PSU. I am a nut about computer noise and heat. I do not need a 600w PSU right now, but it would be nice to have for future upgrades. I have sufficient cooling throughout the rest of my case. Would the 600w psu generate more heat than the 430w psu using the same system?

Also, does anyone know any good alternative PSUs for reduced heat and noise?

I have the Seasonic S12 600W and I :heart: it. It will only output as much power as your components are drawing at any particular time, so they should be identical as far as heat output (and noise, or rather, the lack thereof )

The S12-430 runs a couple of dB quieter than the 600 according to an SPCR review, but the 600 has better efficiency (less heat).
