Thermaltake A2358 Dr. Power Tester

The Dr. Power from Thermaltake is the fastest and easiest way to check your power supply’s health. Designed for ATX 12V 2.0 power supply (backwards support earlier version power supplies), Dr. Power allows you to quickly and easily test +3.3V, +5V, and +12V voltage output. It works perfectly with Molex connectors, P4, floppy, SATA (+5V/+12V), 20-pin or 24-pin connector, and uses green LEDs and beeps to let you know the testing result. If the power output is working, the LED will light and you’ll hear a sound. If the power output fails, you won’t see the LED light or hear any distinctive sound. Built-in load generates steady output.
