Replace Power H350N-00-RPSU-E ATX power supply 350W

Replacement ATX 350 W power supply

This Replace Power H350N-00-RPSU-E is a direct replacement for the Delta ATX0350P5W unit. It delivers 350 W through a single-rail design with a 20+4-pin main connector and a grey chassis. The supply suits owners of compatible Delta, HP or similar desktops needing a drop-in repair part.

Compatibility checks before ordering

Verify that the original unit is a Delta ATX0350P5W or an equivalent ATX supply with the same 20+4-pin main connector. Confirm the system requires the listed rail currents: +3.3 V at 13 A, +5 V at 13 A, +12 V at 16 A, -12 V at 0.8 A, -5 V at 0.5 A and +5 VSB at 2.5 A. Ensure the chassis accepts a standard ATX form factor and that the input voltage switch matches the local 115 V or 230 V mains.

Upgrade context and when it matters

The unit replaces a failed, noisy or overheating Delta ATX0350P5W without changing cables or mounting points. It restores the original 350 W rating and the same voltage rails, so the jump is worthwhile when the old supply has degraded or failed completely. It does not increase wattage or add modern connectors, so builders needing higher power or newer standards should look elsewhere.
