Replacement PSU for HP Desktops

This unit replaces the factory power supply in HP A1129n A1130e A1130n A1132n and A1150Y CTO systems. It uses a standard ATX form factor with reduced depth so it fits the original chassis without modification. A single 80 mm fan provides cooling for stable long-term operation. The grey housing matches the OEM aesthetic.

Upgrade from Failed OEM Units

The jump is worth it when the original supply has failed or shows voltage instability under load. Continuous output is rated at 280 W with a 420 W peak capability. Low ripple and noise specification protects sensitive components. Hi-Pot testing and ROHS CE compliance confirm basic safety standards.

Capacity and Headroom

The 280 W continuous rating comfortably runs typical office configurations with integrated graphics and a few drives. Peak headroom of 420 W handles brief startup surges. Builders who need more storage than three SATA 15-pin connectors or multiple high-power GPUs should look elsewhere.

Questions about this item

Will the 5.86-inch depth fit my HP A1129n case?

The unit measures 5.86 inches deep, shorter than a standard ATX supply, so it clears tight chassis space in the listed HP models.

Which cable should I connect to the 4-pin CPU header on the motherboard?

Use the dedicated P4 4-pin connector; the 24-pin plug splits as 20+4 for the main board power, but the separate 4-pin is for the processor.

How often should I clean the 80mm cooling fan?

Blow dust out of the fan intake every six to twelve months to keep airflow steady and noise low.
