700W redundant server power supply

The Supermicro PWS-704P-1R delivers 700 watts in a 1U redundant form factor for rack-mount servers. It is built for operators who need continuous uptime and hot-swap replacement in enterprise environments.

Hot-swap installation with single-slot fit

The unit slides into a compatible 1U bay and locks with a thumb screw, so no tools are required for a swap. Misalignment of the rear connector is the common issue; the supply must seat fully before the screw engages.

12V rail limited to 58A or 62A

The +12V output is rated at 58 amps or 62 amps depending on input voltage, which caps the power available to modern CPUs and GPUs. The 80 PLUS Gold rating improves efficiency but does not raise the current ceiling beyond the stated figures.
