Replacement PSU for HP Pavilion H8

This Gulfe ATX power supply replaces the original unit in HP Pavilion H8 1121, 1141, 1201ER and 1202ER desktops. It accepts 115 or 230 V input and fits the reduced-depth chassis used by these models. The single fan provides airflow through the compact housing.

Thermals and protection features

Over current and over power protection circuits guard connected components during load spikes. The supplier notes high efficiency and low ripple and noise, with a hold-up time of 17 ms minimum at nominal input. Rise time is less than 70 ms from power-on to stable output rails.

Connectors and mounting implications

The unit supplies a 24-pin ATX (20+4) connector, one 4-pin P4 12 V connector, three SATA 15-pin connectors, two LP4 4-pin connectors and one floppy 4-pin connector. Dimensions are 5.86 inches by 3.3 inches with a weight of 2.5. Builders needing additional SATA or PCIe power beyond this complement will require a different unit.

Questions about this item

How do I install the ATX 24-pin and 4-pin CPU connectors in an HP Pavilion H8 case?

Align the 20+4 pin main connector and the P4 4-pin CPU plug with the motherboard headers; the reduced 5.86-inch depth helps clear tight chassis space. Ensure the 115/230 V switch matches your mains before powering on.

Which components are most likely to need replacement after several years of operation?

The single internal fan is the primary wear item; dust buildup reduces airflow and can trigger over-temperature protection. Electrolytic capacitors on the +12V1, +12V2, +5V and +3.3V rails may also degrade over time.

What is the first limit reached during sustained full-load operation?

The 17 ms minimum hold-up time at nominal input is the first hard limit; if mains dip longer than this, output rails drop. Thermal protection from the single fan will activate shortly after if airflow is restricted.
