Antec 850W TruePower Quattro power supply
 

We ran 3DMark 2006SE in a loop four times in a row and amazingly there was no notice of much heat coming out of the power supply. In fact it felt very near ambient temperatures. Above the hum of of the PC fans the power supply its self was almost totally silent. Antec again have done an excellent job with this line of power supplies, meeting their standard for PSUs that are quiet, put off little to no heat, excellent modular design with shielded cables, while being robust and strong under a full PC load.
