Thermaltake Purepower TWV 500W Power Supply Unit Review



Let me start off by saying that at first, I was a little concerned about reviewing this PSU, but it didn't take long for me to realize by the overall appearance and performance of this PSU that it was going to be an exciting review! What I really love about this PSU was its stability, which going by the multimeter, was rock solid even under a load, and that is the the one thing that everyone should be looking for when it comes to purchasing a power supply. The total watts viewer, in my opinion, is simply for looks as it doesn't display a lot of "useful" information. However, it did make for a welcomed addition in appearance to the front of my case. In addition to the total watts viewer was the fan control knob, which is very useful when wanting to adjust fan speed to fit your custom needs and cooling demands (also, the total watts viewer is easily installed). The other really nice feature of this PSU is its modular cable design, which allows for easy wire connecting and the ultimate friend in wire management. Along with the modular design, each set of wires are sleeved, with heat shrink on each end, to allow for even better air flow and cooling performance. The only thing that I actually found wrong with this PSU was the fact that there was a piece of industrial caulking lodged between the fan and fan grill, which fortunately, was easily removed with a small pair of needle-nosed pliers. Once again, I contacted Thermaltake on this matter and was told that I could return the power supply for a new one without any problems. I was also told: "We have escalated this issue to our headquarters already " so I am hoping they mean to their QC (quality control) department!


  • Rock solid performance, even under full load!
  • Easy installation, both PSU and the total watts viewer
  • Modular cable design along with sleeved cables
  • Unbeatable overall good looks
  • The 120mm fan lights to a bright blue (if you like the blue theme)
  • 500 watts of total power


  • Piece of industrial caulk lodged between the fan and fan grill (which was easily removed)
