Direct replacement for HP Pavilion H8 desktops

This Gulfe ATX unit is built to replace the original power supply in HP Pavilion H8 1050Z, 1055SC and 1056SC systems. It delivers the standard +5V, -5V, +3.3V, -12V, +5V-SB and dual +12V rails through a 24-pin ATX connector, a 4-pin P4-12V connector, three SATA power plugs, two LP4 plugs and one floppy plug. The reduced-depth chassis measures 5.86 by 3.3 inches for easier fitment.

Verify connector requirements

Before ordering, confirm that your motherboard uses a 20+4 pin ATX main connector and a 4-pin P4-12V CPU power connector. Check that the three SATA, two LP4 and single floppy connectors match your drive and peripheral count. The unit accepts 115 or 230 V AC input at 47 to 63 Hz; ensure the voltage selector switch matches your mains supply.

Single-fan cooling with protection circuits

One internal fan provides airflow across the reduced-depth frame. Over-current and over-power protection circuits guard connected components during fault conditions. The supplier notes high efficiency and low ripple and noise, with a rise time under 70 ms and a minimum hold-up time of 17 ms at nominal load. The unit weighs 2.5 units.

Perguntas sobre este artigo

Which cables and connectors come with the Gulfe ATX power supply, and what will I need to source separately?

The unit includes a 24-pin (20+4) ATX connector, one 4-pin P4-12V, three SATA 15-pin, two LP4 4-pin and one floppy 4-pin connector; any additional PCIe or extra SATA cables must be purchased separately.

The listing mentions several HP model numbers — how do I know which version matches my Pavilion desktop?

This replacement is built for the HP Pavilion H8 1050Z, 1055SC and 1056SC; verify your chassis label against those three model numbers before ordering.

What does the 17 ms hold-up time mean for my system during a brief power dip?

At nominal input the supply can maintain all output rails for at least 17 ms, giving the motherboard enough ride-through for short mains interruptions.
