Power supply for compact builds

The Corn Electronics WD500K is a 500 W ATX unit rated for 80 Plus Gold efficiency. It suits builders assembling office or entry-level gaming systems that draw moderate power from the wall.

150 mm depth with hydraulic cooling

A single 120 mm hydraulic fan provides automatic speed control for quiet operation. The compact 150 mm length fits many smaller cases while the 20+4 pin and CPU cables reach 50 cm and 65 cm respectively for tidy routing.

Connector limits define upgrade scope

Two 6+2 pin PCIe plugs restrict graphics choices to cards needing no more than two such connectors. Four SATA power leads and two four-pin peripheral plugs cap the number of drives and accessories you can attach.

Questions about this item

What does the 80 Plus Gold rating mean for a 500 W unit in real use?

The 80 Plus Gold rating means the unit delivers over 85 percent efficiency at typical loads, reducing heat and electricity waste compared with lower-rated supplies.

Will the 150 mm long chassis and 120 mm hydraulic fan fit a standard ATX case?

The 150 mm length and 86 mm height match standard ATX dimensions, and the single 120 mm hydraulic fan mounts in the usual rear or bottom position without clearance issues.

How do I connect the 20+4 pin main cable and the two 6+2 pin PCIe cables without mixing them up?

The 20+4 pin cable is 50 cm long and keyed for the motherboard socket, while the 6+2 pin PCIe pair shares a 65 cm cable — plug the split end into the graphics card and the single end into the PSU.
