Gulfe ATX PSU for HP Pavilion Elite M9400Z M9402F

This new Gulfe ATX power supply replaces legacy units in HP Pavilion Elite M9400Z and M9402F media centre desktops. It delivers standard output rails including +5V, -5V, +12V1, +12V2, +3.3V, -12V and +5V standby. Over-current and over-power protection circuits guard connected components. Reduced depth improves fit inside the original chassis.

Fits HP Pavilion Elite M9400Z and M9402F only

Builders restoring these specific HP models can use this unit as a direct swap. Systems requiring different connector layouts, higher total wattage or proprietary form factors should look at other options. The single fan provides basic cooling for the original hardware configuration. This unit does not support modern high-power graphics cards or newer motherboard power standards.

Connector set decides compatibility

The harness includes one 24-pin ATX connector, one 4-pin P4 12V connector, three SATA 15-pin connectors, two LP4 4-pin connectors and one floppy 4-pin connector. Missing PCIe power plugs rule out discrete graphics upgrades. Verify your motherboard and drive requirements against this exact list before purchase.

Questions about this item

How long will the power supply maintain output after mains voltage drops?

The unit provides a minimum hold-up time of 17 ms at nominal input, keeping rails alive during brief interruptions.

What noise level and thermal load should I expect when the PSU runs continuously?

A single internal fan cools the unit; the supplier notes low ripple and noise but does not publish a decibel rating or thermal output figure.

Which existing cables or motherboard headers must my system already have for this PSU to connect?

Your motherboard needs a 24-pin ATX socket and a 4-pin P4 12 V header; drives require SATA power ports or LP4 connectors.
