Thermaltake Purepower 680W

The Purepower from Thermaltake is the beast of our roundup today coming in with a total of 680W. The unit is also the largest and heaviest of all the PSUs we're looking at today with an extra half inch of girth. Though it's difficult to see in the image below, the finish is actually a nice mirror effect and not all black. Though the finish looks great, I've found it's horrible for picking up fingerprints.

Aimed at high end hardware users the Purepower is packed with connections and features. Based on the latest ATX 2.20 spec, the  Purepower features three 12V rails at 14A, 23A and 15A respectively. This allows each the IDE devices, the CPU/motherboard, and any PCI-E connectors to each have their own dedicated 12V feed. The Purepower also features Universal Input, SSI EPS12V compliance as well as 80% efficiency. The unit as you can see also features Active PFC.

Instead of the single 120mm fan found on most units in this roundup, the Purepower instead goes with two 80mm exhaust fans. Though the dual fans move more air through the unit, they also bring a higher noise level with them seen later in our testing.

The Purepower comes with not only individually wrapped cables, but with color coordinated ones as well. Here we see the black ATX connector along with the red/orange PCI-E and EPS12V connectors. The different colors indicate which rail the cables are being powered by.

Aside from being color coordinated the cables on the Purepower are also extra long which means that they will have no problems reaching their destinations even in full tower server cases. If howerver you are using a smaller mid tower case, the extra length could potentially block of some 5.25 bays.

An additional plus on the aesthetic side is the black connector ends for all cables except the "Case Fan Only" connectors.

The Purepower 680 from Thermaltake includes the following connectors

  • 20+4 pin ATX connector
  • 4+4 pin CPU power connector
  • 2 x PCI-E 6-pin connectors
  • 8 x standard 4-pin molex connector
  • 4 x 5-pin SATA connectors
  • 2 x floppy connectors
  • 2 x Case Fan Only Molex Connectors

The Purepower is equipped with OVP, UVP, SCP, OCP as well as overload and over-temperature protective circuitries. It also complies with CB, CE, FCC, UL, CUL and TUV certifications.
