650 W ATX power supply

The Corn Electronics WD650K delivers 650 W of continuous power in a standard ATX form factor. It targets system builders who need reliable energy for mid-range components. The unit carries 80 Plus Gold certification and uses an LLC plus DC-DC topology with active PFC across an 80 to 280 Vac input range.

Sustained load behaviour

Under continuous demand the 120 mm hydraulic fan adjusts its speed automatically to balance airflow and noise. The platform maintains efficiency above 85 % while protections for over voltage and overload guard the connected hardware. A mean time between failures rating exceeding 50 000 hours reflects the design focus on long-term stability.

ATX connector complement

The supply provides a 20+4 pin main connector, two 6+2 pin PCIe leads and four SATA power plugs. Two 4+4 pin CPU cables each measure 70 cm in length. Physical dimensions are 150 mm long, 140 mm wide and 86 mm high, fitting cases that accept standard ATX units up to 150 mm deep.

Questions about this item

How loud does the 120 mm hydraulic fan get under continuous full load?

The 120 mm silent hydraulic fan uses automatic speed control to balance airflow and noise; at typical loads it stays quiet and only ramps up when internal temperatures rise.

Which cables must my build already provide for the 20+4 pin main and 4+4 pin CPU connectors?

This unit includes a 20+4 pin ATX main cable and a 4+4 pin EPS cable, so the motherboard only needs the matching 24-pin and 8-pin sockets.

Will the 650 W output and 6+2 pin PCIe plugs support an older graphics card that still uses a single 6-pin connector?

Yes, each 6+2 pin PCIe cable can be used as a straight 6-pin plug, delivering up to the unit's 650 W total capacity for legacy GPUs.
