Replacement for Dell Optiplex GX620

This 400w ATX power supply is built as a direct replacement for the Dell Optiplex GX620 Mini Tower and PowerEdge SC440. It suits owners of those specific systems who need to restore power after a failure. The unit also fits other desktops requiring the same connector layout and form factor.

Grey ATX unit with 20+4 pin motherboard connector

The grey chassis measures 5.8 by 3.37 and houses a single fan. A 20+4 pin ATX connector works with both 20-pin and 24-pin motherboards. Additional cables include one P4 12V 4-pin, three SATA 15-pin, two Molex 4-pin and one Floppy 4-pin connector for drives and peripherals.

Check connector count

Verify that your motherboard uses a 20-pin or 24-pin main power socket and that the case can accept a supply of the stated dimensions. Ensure the three SATA and two Molex leads match your drive count. Builders needing more SATA ports or a different form factor should look elsewhere.

Questions about this item

What motherboard power connector does the RPSU-C95-15 provide and which pin counts does it support?

The unit ships with a 20+4 pin ATX connector that fits both 20-pin and 24-pin motherboard sockets.

What are the physical dimensions of the RPSU-C95-15 and will it fit a Dell Optiplex GX620 Mini Tower?

It measures 5.8 by 3.37 inches and is listed as a direct replacement for the Optiplex GX620 Mini Tower and PowerEdge SC440 chassis.

How is the RPSU-C95-15 installed and which step is most often missed?

Secure the unit with four screws, plug the 20+4 pin ATX and 4-pin P4-12V cables into the motherboard, then attach SATA, Molex and floppy leads to drives; the step most often missed is connecting the 4-pin P4-12V cable, which leaves the CPU without power.
