A 700 W 2U server power supply with 80 Plus Bronze efficiency, dual fan cooling and EPS-12V support for Xeon motherboards
The Athena Power 700W unit fits a 2U rackmount chassis and provides a single 700W output with 80 Plus Bronze certification. It supports ATX V2.3 and EPS-12V Xeon motherboards, making it suitable for compact industrial or server builds. The 20+4 pin main connector plus an EPS 8-pin and an additional P4 4+4 pin connector cover dual-processor configurations.
Two fans positioned at the front and rear move air through the power supply, with the rear fan drawing internal system heat out through the front. A built-in controller monitors temperature and adjusts fan speed automatically, keeping noise and thermals in check during normal operation. The Bronze-rated efficiency reduces waste heat at typical loads.
The supply includes two PCI-E 6-pin connectors for graphics cards running in multi-GPU arrangements, freeing the builder from sourcing adapters. Its 2U height limits vertical space, so the surrounding chassis must accommodate that form factor. No modular cabling is mentioned, so cable routing should be planned around the fixed harness.
Measured against everything we stock in Rackmount Server Cases, at today’s prices. Recalculated every night.

Mount the 2U chassis with the front fan facing the cold aisle, connect the 20+4 pin ATX, the EPS 8-pin and the extra 4+4 pin CPU cables, then route the two PCI-E 6-pin leads to the graphics cards — the step most builders skip is securing the rear exhaust path so the front fan can pull heat through the PSU.
The dual fans at the front and rear should be cleaned of dust every few months; the automatic speed controller adjusts airflow based on internal temperature, so keeping the intakes clear preserves the thermal curve.
The 80 Plus Bronze rating guarantees the certified efficiency floor up to 700 W output; sustained draws at or above that level will hit the power ceiling before any thermal throttle activates.
