Dell TD570 275 W Power Supply

This 275 W internal power supply is built for the Dell OptiPlex GX620 desktop. It accepts 127 V or 240 V AC input and delivers a single +12 V rail rated at 17 A alongside 3.3 V, 5 V and -12 V outputs. The unit is supplied new and matches the original TD570 part specification.

Who this suits and who should look elsewhere

It suits anyone restoring or repairing an OptiPlex GX620 that requires the exact factory power connector layout and 275 W rating. Builders working on other chassis, different OptiPlex models, or systems needing higher wattage or multiple +12 V rails should look elsewhere.

The specification that decides fit

The decisive figure is the 275 W total output combined with the proprietary connector pinout designed solely for the GX620. If your build demands that exact power rating and physical interface, this supply matches; otherwise it will not fit.

Questions about this item

Will the Dell TD570 275 W unit power my existing OptiPlex GX620 desktop without modification?

Yes, the TD570 is built specifically for the OptiPlex GX620 and fits the internal form factor of that chassis.

How can I verify the Dell TD570 is delivering the correct rails after installation?

The supply provides 3.3 V at 5 A, 5 V at 18 A, 12 V at 17 A, -12 V at 500 mA and 5 V standby at 1 A; measure each rail with a multimeter under load.

What connectors and cables come with the Dell TD570 power supply, and what must I source separately?

The unit ships as the internal power supply module only; the AC mains cord and any motherboard or drive power cables already present in the GX620 are reused.
