Genuine Dell 375 W PSU for legacy workstations

This genuine Dell KH624 power supply delivers 375 W and is built for Dimension 9100, 9150, 9200, XPS 400, 410, 420, 430 and Precision Workstation 380, 390, T3400 systems. It provides the exact connector layout those chassis expect, including a 24-pin ATX motherboard plug, a 4-pin P4 plug, six SATA power leads, one 4-pin Molex, one floppy plug and a single 6-pin PCI Express connector. The unit is a direct replacement for the original factory part.

Suits owners restoring listed Dell models.

This unit suits owners restoring the Dell models listed above who need a tested, genuine replacement. It is not for builders using standard ATX cases or modern motherboards that require additional PCIe power, an 8-pin EPS connector or higher total wattage. The proprietary pin-out and mounting tabs prevent installation in generic chassis, and the single 6-pin PCIe lead cannot support graphics cards needing dual power inputs.

375 W total output with one 6-pin PCIe connector

The single specification that decides fit is the 375 W total output combined with exactly one 6-pin PCI Express power connector. If the target system demands more than 375 W or requires two or more PCIe power leads, this supply will not meet the requirement.

Questions about this item

How do I install the KH624 power supply and which connector is often missed?

Remove the old unit, slide the KH624 into the chassis, secure it with four screws, plug the 24-pin ATX motherboard connector (P1) and the 4-pin P4 motherboard power connector (P2); the P2 connector is the step most people forget.

What maintenance or replacement will the KH624 need later?

The internal fan and electrolytic capacitors age over time; expect to replace the whole unit after several years of continuous use rather than servicing individual parts.

What limit appears first on the KH624 under sustained load?

The 375 W maximum power rating is the first limit reached during sustained heavy use; the single 6-pin PCI Express connector also caps GPU power delivery.
