Thermaltake Purepower 520 PST, we specifically tested model W0073 which has active PFC as explained a page ago. I really do recommend you this model over the passive PFC model.

PurePower Power Station 520w supply comes with the PSU unit, main distribution box (PST) and two boxes with all the other necessary items such as cables, mini PST unit and a very decent written manual.

Metrics: A 12cm cooling fan that spins at 2,000 rpm when at 100% load/heat, very low noise yet air is still being pushed through the Thermaltake Power Supply, more than enough to ensure cool air which of course is also drawn through your computer case. BTW, the main ATX power cable is 24-Pin, but can be converted to 20-Pin should your motherboard require it.

One of the first things you'll notice are the ventilation holes. They allow much more air to flow through compared to the round holes found on most PSU supplies which means a cooler case. That's like looking at a girl with a very sexy shirt.
