Adrian's Rojak Pot has just posted the Powering Up A Standalone PSU Guide. If you need to test some fans or cold cathode tubes, it can be a hassle hooking them up to a case. Why not use a standalone PSU?
This quick guide will show you just how to power up a standalone PSU for quick and easy tests of accessories and other components that require electrical power.
You can check out the guide over here. A couple of years ago I wrote a similar guide, you can find my guide over here.
