TweakNews posted a review on the Thermaltake Purepower TWV 500W PSU

Thermaltake has done a good job with their first entry into the modular power supply market. The TWV 500W sells for around $130US, putting it at the high end of the spectrum, price wise. The inclusion of a case fan and the TWV module offsets the high price somewhat, if the prospective buyer finds these features desirable. Many online retailers have this unit in stock and ready to ship. The short U-bracket design of the TWV module may be an issue in some cases with tool free drive configurations. This PSU has been in operation for the past week or so and I’ve had no issues with it. It looks good, works well and has some excellent features.
