Most computers have some extra 4-pin power plugs / connectors from the power supply. These plugs have metal connector pins that could touch the metal case if moved around inside your computer case, causing shorting of the entire power supply and PC. Here is an inexpensive tool to help you to prevent that from happening!
Plastic end-cap / cover for 4-pin power connectors. Plug this cover to any unused power connectors, making it impossible for the metal pins to touch other metal parts inside your case. A great, but often overlooked, item for any PC technical room or system builder.
Loosely packed. Color: blue. Part No.: VDC. Price: $2.00 per cover and $5 for five.
