Blue Screens, random reboots, dead machines, failed boots, and other intermittent problems can all be linked back to a faltering power supply.

There are ways to test some components in the computer easily enough, but the power supply is a tricky one. If the problem only happens once in awhile Dell Inspiron 6000 Battery, it could take a very long cheap time to figure out. Because of this, there is a special power supply testing tool that we can use that will not only identify problems on the main power connector of the power replacement supply, but on every single one to ensure that it is functioning at 100%.

Multiport Power Supply Testers

Newer, more advanced multi-connector power supply testers have many shop different sockets on them so that you can test every single cable on the power supply. The one linked above from Newegg.com is only $14 and includes sockets for 20+4 P1, SATA, 4 cheap pin, 6 pin and 8 pin power connectors. A series of lights indicate whether there is a problem or not, as you cycle through the various connectors on the power supply.

Running charger the Test

In order to use a power supply tester, you might have to remove the power supply from the case first.

For 4/6/8 pins, +12V should be lit. For Floppy, +12 acer aspire and +5V should be lit. For SATA, +12 hp pavilion dv6500 Battery, +5 and +3.3V should be lit.
