Compatible ATX Replacement

This Gulfe ATX power supply replaces several older legacy units for the HP Envy h8-1492d desktop. It accepts input voltage of 115 or 230 V and operates at 47 to 63 Hz frequency. The unit features a reduced depth design measuring 5.9 inches in height and 3.4 inches in width for increased compatibility. Over current and over power protection are included for system safety.

Builders Needing Legacy Connectors

This unit suits builders restoring or repairing the specified HP Envy desktop who require legacy connector support. It provides a 24-pin ATX connector, a P4 12V 4-pin connector, three SATA 15-pin connectors, two LP4 4-pin connectors, and a floppy 4-pin connector. Builders needing modern GPU power connectors such as 6-pin or 8-pin PCIe should look at something else. The single fan design may limit airflow in high-heat chassis configurations.

Sustained Load Protection

Under sustained load, the power supply maintains stable output across +5V, -5V, +12V1, +12V2, +3.3V, -12V, and +5V-SB rails. High efficiency operation keeps ripple and noise low during continuous use. Hold-up time is rated at a minimum of 17 ms at nominal input, while rise time stays under 70 ms. These protections help prevent unexpected shutdowns during extended work sessions.

Questions about this item

Does my motherboard need a 24-pin ATX and a 4-pin P4-12V connector to use this Gulfe ATX unit?

Yes. The supply ships with a 24-pin (20+4) ATX connector and a separate P4-12V 4-pin connector, both required for standard desktop boards.

Will the 5.86-inch depth fit in the same space as the original HP Envy h8-1492d power supply?

The reduced-depth chassis measures 5.86 inches deep by 3.3 inches wide, matching the legacy form factor so it slides into the existing bay without modification.

How can I verify the +12V, +5V and +3.3V rails are delivering power after installation?

After power-on, the system should POST normally and the single fan will spin; use a multimeter on the 24-pin and SATA connectors to confirm each rail reads within spec.
