What this power supply fits

This Gulfe ATX unit is built as a direct replacement for HP Pavilion Desktop models H8 1011NL 1012IT and 1020NL. Its reduced-depth chassis measures 5.86 inches by 3.3 inches, allowing it to slide into tight legacy cases where a full-length PSU would not fit. The 24-pin ATX connector, a 4-pin P4-12V plug, three SATA power leads, two LP4 connectors and one floppy connector cover the typical drive and motherboard needs of those systems.

Check your case and cables before ordering

Verify that your chassis can accept a power supply 5.86 inches deep and 3.3 inches wide, as the reduced depth is the critical clearance dimension. Confirm the motherboard uses a standard 24-pin ATX main connector and a 4-pin P4-12V CPU power plug; some older boards may only have a 20-pin main socket, in which case the 20+4 pin design still works. Ensure the three SATA, two LP4 and single floppy connectors match the drives you plan to power.

Replaces legacy units in compact HP desktops

This supply swaps in for the original equipment power supply used in the listed Pavilion H8 desktops, restoring reliable power with over-current and over-power protection. The jump is worth it when the old unit has failed, shows voltage instability or lacks the SATA connectors needed for newer drives. It is not for builders who need higher wattage than the original design, modular cabling, or a standard-depth ATX form factor for full-size cases.

Questions about this item

Does the box include every cable needed for a typical desktop build, or must I purchase extra SATA or floppy leads?

The unit ships with one 24-pin ATX, one 4-pin P4, three SATA 15-pin, two LP4 4-pin and one floppy 4-pin connector, covering most legacy and current drives without extra cables.

The title lists H8 1011NL 1012IT 1020NL — which of these model numbers matches my HP Pavilion?

All three model numbers are supported; choose the one printed on your original power-supply label to confirm an exact replacement.

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

It guarantees the PSU maintains regulated output for at least 17 milliseconds at nominal load, giving the motherboard time to ride through short interruptions.
