Thermaltake Power Express 250W Review

The PSU »


I would like to thank Thermaltake for supplying the tested unit.

The Power Express is a video card power supply specifically designed for the needs of current high-end video cards. When you have an older PSU you may not be able to run Crossfire or SLI because the PSU can not supply enough power for the video cards to run stable. A solution is the Power Express which has 250W of power that are available to up to two video cards.
