Watch my video on how to use the Thermaltake Dr. Power ATX 12V 2.0 Power Supply Tester to test your computer power supply’s voltage rails like your 12V, 5V, and 3V rails.
Before you test your computer power supply, make sure your computer is off, and unplugged. Next, disconnect the 20pin or 24 pin, 4 pin P4 connector from your computers motherboard, and all the 4 pin molex drives from your CD drives, hard drives, and fans. Finally, unscrew your power supply from your PC case
1. Plug your power supply’s 20pin or 24 pin power cable into the power supply tester, and also plug in the P4 4pin power plug, 4 pin molex connectors, and floppy power cable into the power supply tester.
2. When your 20 pin, 4pin P4 connector,4pin molex and floppy power cable is all plug into the tester, plug your power supply into the wall outlet.
3. Plug in your power supply to the wall outlet. Some power supplies also have an on/off switch at the back. Make sure the on/off switch is set to on.
4. If your power supply is not broken, all the lights will turn on, but if it is broken, one or more lights won’t turn on on the power supply tester.
Do not fix broken power supplies since they contains dangerous amounts of electricity, so you should just replace power supplies with a working one.
The Thermaltake Dr. Power ATX 12V 2.0 Power Supply Tester is a great power supply tester since it is easy to use, portable, and seem very durable when I use it, and it only cost me less then 27 dollars.
Hello, this is a genuinely terrific blog post. In principle I’d wish to create articles like this as well taking time and real effort to make a great post but what can I say I procrastinate a lot and by no means appear to obtain something done. Thank You
