500W replacement PSU for OptiPlex MT

The WMtec L500EPM-00 is a new 500W server power supply built to fit Dell OptiPlex 7080MT, 7070MT, 7060MT, 3050MT, 3650, 3670, 3671, 5090, 3260 and 3681 mini-tower chassis. It accepts 100-240V input at 50/60Hz and delivers up to 500W total output through three +12V rails rated at 18A each. Part numbers 99TPH, Y7R0X and 5K7J8 cross-reference to this model.

Suits owners of listed OptiPlex MT units

This unit matches the factory connector layout for the systems named above, providing GPU 8-pin, GPU 6-pin, an additional 6-pin and two 4-pin leads. Builders working on other form factors, proprietary small-form-factor OptiPlex models or non-Dell platforms should verify pin-outs and mechanical fit before purchasing.

Three +12V rails at 18A each

The power supply splits its 12V delivery across three independent rails, each capable of 18A. This rail configuration determines whether the unit can support the graphics cards or add-in boards planned for the compatible OptiPlex MT systems.

Questions about this item

How do I install the L500EPM-00 into an OptiPlex 7080MT, and which cable often gets missed?

Slide the unit into the chassis until it clicks, then attach the 24-pin motherboard plug, the 4-pin CPU plug and the 8-pin GPU plug; the 6-pin GPU cable is the one most often left unconnected.

What maintenance will this 500W unit need after a year of daily use?

Clean the intake vents and fan blades with compressed air every six months; the internal fan is the only moving part and will eventually need replacement if noise or vibration appears.

Which output rail hits its limit first when the OptiPlex 7070MT runs a sustained heavy load?

Each +12V rail is rated at 18 A; the rail feeding the graphics card typically reaches that ceiling before the CPU or motherboard rails do.
