ATX/EPS12V 800 W power supply

The E-POWER EP-800PM delivers 800 W across two +12 V rails rated at 20 A each, with a 24+8 pin main connector and active PFC. It is built for desktop systems that need SLI or CrossFire support and Haswell compatibility. The non-modular design keeps all cables attached for a fixed wiring layout.

Non-modular cabling and 160 mm depth

Installation means routing every fixed cable, including two 6-pin and two 6+2-pin PCIe leads plus eight SATA power plugs. The single 140 mm fan handles cooling, so the 160 mm case depth must be clear. Cable bulk behind the motherboard tray can restrict airflow if the chassis is tight.

Dual +12 V rails and connector count

Check that the motherboard accepts the 24+8 pin main power and that the graphics cards match the available PCIe connectors. Verify the chassis fits a 160 mm deep unit and that the 115/230 V input switch matches the local mains. The 75 % efficiency rating and fixed cable set suit builds that do not need modular flexibility.

Questions about this item

How can I confirm the 800W unit is delivering stable power after installation?

Check that the 140mm fan spins and the system boots without shutdowns; a multimeter on the 24+8Pin main connector should show +12V rails near 12V and +5V near 5V under load.

What cables come attached to the non-modular PSU and what must I source separately?

The unit ships with a fixed 24+8Pin main connector, two 6-Pin and two 6+2-Pin PCIe cables, and eight SATA power leads; no extra cables are included.

Which 800W version suits a dual-GPU build needing four PCIe plugs?

This single EP-800PM model already provides two 6-Pin and two 6+2-Pin connectors, covering SLI or CrossFire setups without a second variant.
