Replacement PSU for OptiPlex and Vostro MT

This 400 W power supply replaces the original L400EPS-00 or D400EPS-00 unit in OptiPlex 3000MT, 5000MT and 7000MT towers as well as Vostro 3710, 3910 and T3660 systems. It accepts 100-240 V input at 7.0 A across 50-60 Hz mains frequency. The part matches Dell part numbers X4XV7 and XYD3F for direct swap-in.

Connector layout: (4+4+8) pin plus (8 pin)

The unit provides a combined (4+4+8) pin connector alongside a separate 8-pin connector to feed the motherboard and CPU power rails. This specific pin arrangement is required by the listed OptiPlex and Vostro motherboards. Builders whose boards use a different CPU power pinout cannot use this supply.

Steady 400 W DC output under load

The supply is rated for a maximum continuous DC output of 400 W rather than a short-term peak. It maintains this level while the system draws sustained power from both the main and CPU connectors. Systems configured with higher-wattage components that exceed this continuous limit will need a higher-capacity replacement.

Questions about this item

What does the 400 W maximum output mean for a tower PC?

It sets the total DC power ceiling for the CPU, graphics card, drives and fans combined; sustained loads above that level will trip the protection circuit.

What does the 100-240 V 50-60 Hz input range cap in practice?

The unit auto-ranges across worldwide mains voltages, so it works on any standard office or household circuit without a selector switch.

Will the (4+4+8) pin plus 8-pin connector set fit an OptiPlex 7000 MT chassis?

Yes, the cable bundle matches the motherboard and CPU power headers used in the OptiPlex 7000 MT and the other listed towers.
