Dell MC164 305W PSU for OptiPlex GX620

This 305 watt mini-tower power supply is built specifically for the Dell OptiPlex GX620 desktop. It delivers the exact voltage rails and connector layout that the original chassis requires. System builders restoring or repairing that platform can install it without adapter cables or case modifications.

Steady 305 watt output under continuous load

The unit is rated to maintain its full 305 watt capacity during sustained operation rather than only in short bursts. This ensures stable power for the processor, memory and onboard devices throughout extended work sessions. It is not suited for systems that demand higher continuous wattage or additional peripheral connectors.
