305 W ATX supply for Dell OptiPlex and PowerEdge

This 305 W ATX power supply carries Dell part number WU133 and is built to fit specific OptiPlex and PowerEdge chassis. It accepts 100-240 V input at 50/60 Hz and delivers power through a 24-pin ATX connector, a 4-pin ATX connector, four SATA connectors and a floppy connector. The unit is sold in refurbished condition.

Suits owners of listed Dell desktops.

The supply matches the pin-out and mounting of OptiPlex 320, 330, 360, 580, 740, 745, 755, 760, 960, Dimension 5200, E520, E521 and PowerEdge SC, T100 and T105 systems. Builders using standard ATX cases or motherboards with different connector layouts should look elsewhere because the wiring and bracket are proprietary to those Dell models.

305 W maximum output

The 305 W rating is the single figure that determines whether this unit can support the installed components. If the combined draw of the CPU, drives and expansion cards exceeds this limit, the supply will not be adequate.

Perguntas sobre este artigo

Will the 24-pin ATX connector on the WU133 fit the motherboard in my Optiplex 760?

The WU133 provides a 24-pin ATX connector and is listed as compatible with the Optiplex 760, so it will connect directly to that motherboard.

How can I confirm the unit is delivering stable power after installation?

After fitting the WU133, the system should power on reliably and run without unexpected shutdowns under normal load.

Does the box include the four SATA power cables needed for my drives?

The WU133 has four SATA power connectors built into its cable harness, so no separate SATA power cables are required.
