Targeted replacement

This ATX power supply is built to replace the original unit in HP Pavilion H8 1031NL, 1034DE and 1035CN desktops. Its reduced depth helps it fit the proprietary chassis without modification. The unit delivers the standard +5V, -5V, +12V1, +12V2, +3.3V, -12V and +5V-SB rails required by those systems.

Thermals and protection

A single fan provides airflow through the compact housing while over-current and over-power protection circuits guard connected components. 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 input. AC input accepts 115 or 230 V at 47 to 63 Hz.

Connector bundle

The fixed cable set includes a 24-pin ATX connector, one 4-pin P4 12V plug, three SATA 15-pin connectors, two LP4 4-pin plugs and one floppy 4-pin connector. This mix covers the motherboard, processor, drives and legacy peripherals found in the target HP models without needing adapters.

Questions about this item

How do I install the 24-pin ATX connector and the 4-pin P4 power cable without forcing them?

Align the 20+4 pin ATX connector with the motherboard keying and press until the latch clicks; then plug the P4 4-pin cable into the CPU power header, matching the square and rounded pins exactly.

Which parts of this power supply are most likely to need replacement after long-term use?

The single internal fan is the primary wear item; dust buildup on its blades reduces airflow, so plan to clean or replace the fan if noise or temperatures rise.

What is the first limit reached when the unit runs at full load continuously?

The 17 ms minimum hold-up time at nominal input is the first hard limit; if mains power dips longer than that, output voltage will drop before the protection circuits act.
