Overall, Thermaltake's PurePower 500W is a very impressive power supply with an excellent retail package. The versatile Socket Design for the connections is something you'll be grateful of, mostly because of the convenience it provides and secondly because it avoids unnecessary cables floating around inside the case making it tidier and less cluttered. There are power cables for IDE, SATA and the floppy drive as well as cables for VGA cards (two, just in case you use SLI), and a 20-pin and 24-pin power cable included to support all the current motherboard platforms.
The Total Watts viewer is something else you don't normally find on any regular power supply. You can monitor in real-time, the power consumption while with the two controllers, you can adjust independently, the rotation speeds of the PSU and case fans. An in case your case doesn't have a fan installed, no problem. Thermaltake has taken care of this by supplying an extra 12cm fan, bundled along with the PSU.
The performance of the PurePower was rather stable according to our tests while the noise was negligible, as long as you keep the fan rotation speed close to minimum. Otherwise, with the PSU fan speed set to maximum, the noise is quite annoying although air flow is extremely good.
At the time of this review, the price for the Thermaltake PurePower 500W, according to the manufacturer, was close to US$165, which is a little high but keeping in mind the good performance, the complete package and the extra features such as the Socket Design and the Total Watts Viewer, we believe that the PurePower 500W is a good purchase.
