Athena Power 800W Flex ATX Server PSU

The Athena Power AP-MFATX80P868 is an 800W Flex ATX power supply built for 1U rackmounts, mini-ITX and other small-form-factor servers. It delivers up to 64A on the 12V rail and carries 80PLUS Platinum certification for high efficiency across loads. The unit accepts 90–264V input at 47–63Hz and meets UL 62368-1 safety standards. It is intended for integrators and operators who need dense, reliable power in compact enclosures.

12V-2X6 cable and ATX 3.1 support

A native 12V-2X6 connector is included, enabling direct connection to ATX 3.1 and PCIe 5.0 graphics cards without adapters. The supply complies with Flex ATX-12V and EPS-12V specifications and provides a 20+4 pin main connector plus standard peripheral outputs. Active PFC and full-range input simplify deployment across regions. No modular cables or software utilities are mentioned in the data.

150mm depth fits tight chassis

At 150mm long, 81.5mm wide and 40.5mm high the unit slides into 1U and SFF cases where standard ATX units cannot. A single 12V DC exhaust fan with thermal speed control handles cooling; the 250000-hour MTBF rating reflects testing at 25°C under full load. Installers should verify that the fixed cable lengths reach their backplane or GPU routing paths. Remote on/off control is available for managed environments.

Questions about this item

How long is the fan rated to run before it needs replacement?

The unit has a mean time between failures of 250000 hours at full load and 25 degrees Celsius, so the fan should last many years of continuous use.

Which protection circuit trips first when the 12V rail is pushed hard?

Over-current protection on the 12V output activates at 64A, limiting sustained draw before voltage drops or thermal limits are reached.

How loud does the exhaust fan get during all-day operation?

A thermal speed controller adjusts the 12V DC exhaust fan to match load, keeping noise proportional to the power being delivered.
