Thermaltake PurePower 520W is the newest product in their P.S.U. product series. Thermaltake used a patented design, promising better cable arrangement. This has been achieved with the P.S.T. unit that uses a 5.25" drive bay. Only 3 cables are connected to the P.S.U. unit, two PCI-Express cables, and a cable to power the P.S.T. (and of course the required 24-pin and 12V motherboard cables).

The P.S.T. looks pretty nice at the front of the PC case, and has three indicator leds to indicate safe operation of the voltage rails. There is also a mini P.S.T. unit to power up low consumption devices, like fans.

The performance of the PurePower 520W was really stable, even when we pushed the system to its limits, practically powering every device available. There was no significant fluctuation in voltage. However, we had a problem operating 2 7800GTX reference cards. It seems that stability was reduced for the 12V rails when it came to maximum Ampere conditions (30A). On the other hand, we had no problem working with 2 6800Ultra cards, which theoretically consume similar amounts of power.

All in all, the Thermaltake Pure Power 520W is a good P.S.U. unit, that will make your PC case look better with its P.S.T. units and the blue fans. When this review was being carried out the price for the Thermaltake PurePower 520W was close to $150, which is even cheaper than the PurePower 500W P.S.U.
