Industrial workstation power

The Athena Power AP-PS3280P868 is an 800W PS2 server power supply built for industrial and workstation systems that demand continuous, stable output. It carries 80 PLUS Platinum certification and IEC/UL 62368-1 safety approval, making it suitable for environments where efficiency and compliance are required.

PS2 form factor integration

The unit fits a standard PS2 chassis measuring 140 x 150 x 85 mm and includes a single integrated cooling fan for thermal management. It accepts a wide 100-264V AC input range at 47-63 Hz, allowing deployment across global power grids without additional configuration.

Legacy redundancy replacement

This single-unit design replaces older redundant PS2 modules where a non-redundant 800W solution is now sufficient, and it adds a P5 16-pin connector for PCIe 5.0 graphics support. It is not for builders who need hot-swap redundancy or systems that require a different form factor.

Questions about this item

How long can the AP-PS3280P868 run at 800 W before the 100,000-hour MTBF limit becomes a concern?

MTBF is rated at 100,000 hours at maximum load and +25 °C, so sustained 800 W operation at room temperature stays within that design target.

What noise and heat should I expect from the single fan when the supply runs at full load all day?

The 80 PLUS Platinum rating means over 92 % efficiency, so waste heat is minimised; the integrated fan is the only active cooling and will run continuously under full load.

Which motherboard power connectors must my system already have to use this PS2 unit?

Your motherboard needs a 20+4 pin ATX socket, an EPS 8-pin (or 4+4) CPU socket, and at least one PCIe 6+2 or 8-pin connector for graphics; the unit also provides SATA and Molex leads for drives.
