  • Tested working so it arrives ready to install
  • Good quality components support reliable operation

Server-grade ATX power unit

This 400 W ATX supply is built for rack-mount servers such as the R310 platform and carries the DPS-400AB-7 A and D400E-S0 designations. It suits IT teams refreshing fleet hardware or integrators assembling 1U and 2U chassis that require a tested, server-class unit.

400 W continuous with 107 W and 130 W rail headroom

The unit delivers 400 W total output and has been verified working under load. It comfortably powers dual-socket configurations with moderate storage arrays but runs out of headroom when dense GPU accelerators or large drive counts push combined rail demand beyond the rated limits.
