Compact 800 W Micro SFX for custom builds

This Athena Power Apollo Series unit delivers 800 W in a Micro SFX form factor measuring 2.5" x 4.9" x 5.2". It targets builders of mini-ATX cases, HTPCs and mini-servers who need high output from a small chassis. The 88–264 V full-range input with Active PFC handles worldwide mains without a voltage switch. It is not for buyers who need ATX or SFX-L dimensions or redundant server supplies.

Straightforward cable routing with fixed leads

All connectors are native to the unit: 20+4-pin ATX, one 4-pin and two 8-pin EPS, two 6-pin and two 6+2-pin PCIe, eight SATA, two Molex and one floppy. The fixed cables simplify inventory but cannot be removed for custom sleeving. Builders must verify that the supplied EPS and PCIe counts match their motherboard and GPU requirements before ordering. No modular cables or adapter kit is included.

Dual +12 V rails rated for sustained 800 W

The two +12 V rails each supply 32 A, with +3.3 V at 20 A and +5 V at 22 A, allowing continuous 800 W delivery. Hold-up time is 17 ms at nominal input, and MTBF exceeds 100,000 hours. Dual fans cool the unit under prolonged load. It is not for systems that draw more than 800 W continuously or require single-rail +12 V designs.
