Direct Replacement for HP Pavilion Desktops

This ATX power supply replaces the original unit in HP Pavilion H8 1037KR 1039 1040 1041 models. It fits the same mounting points and uses the same connector layout. The reduced depth helps it clear tight chassis spaces. It is a new unit built to match the factory specifications.

ATX Interface and Protection Limits

The unit delivers power through a standard 24-pin ATX connector plus a 4-pin P4-12V connector for the CPU. It provides three SATA power connectors, two LP4 connectors and one floppy connector. Built-in over-current and over-power protection shut the supply down if limits are exceeded. Hold-up time is rated at 17 ms minimum at nominal load.

Capacity and Headroom for Legacy Builds

Output rails include +5V, -5V, +12V1, +12V2, +3.3V, -12V and +5V standby to support older motherboards and drives. The supply accepts 115 or 230 V input at 47 to 63 Hz. Rise time is under 70 ms. It is not suited for modern high-wattage graphics cards or multi-GPU configurations that demand additional PCIe power connectors.

Questions about this item

Which Gulfe ATX power supply version fits my HP Pavilion H8 1037KR, 1039, 1040 or 1041 desktop?

This single model replaces the original supply in all four listed HP Pavilion H8 series desktops, so no capacity choice is needed.

What does the 17 ms hold-up time mean once the unit is installed?

It guarantees the +12 V, +5 V and +3.3 V rails stay within spec for at least 17 milliseconds after mains loss, giving the motherboard time to shut down cleanly.

How does the 24-pin ATX connector limit what I can connect?

The 20+4 pin ATX connector fits both 20-pin and 24-pin motherboards, while the single 4-pin P4, three SATA, two LP4 and one floppy connector cover the drives and CPU power on these HP systems.
