Direct replacement for HP Pavilion m8200n

This ATX power supply is built as a direct replacement for the HP Pavilion M8200N and Media Center m7177a desktops. It matches the original form factor with a reduced depth of 5.86 inches by 3.3 inches to fit tight chassis spaces. The unit delivers the necessary voltage rails including +5V, -5V, +12V1, +12V2, +3.3V, -12V and +5V-SB. It suits owners restoring or repairing these specific legacy systems.

Thermals noise and power draw

A single fan manages airflow through the reduced-depth housing while the unit operates on 115 or 230 V AC input at 47 to 63 Hz. Over-current and over-power protection circuits engage during fault conditions to protect connected components. The design targets high efficiency with low ripple and noise, maintaining a hold-up time of 17 ms minimum at nominal load and a rise time under 70 ms. The unit weighs 2.5 units as specified.

Connector bundle and compatibility

The cable harness includes a 24-pin ATX connector configured as 20+4 pin, one P4 12V 4-pin connector, three SATA 15-pin connectors, two LP4 4-pin connectors and one floppy 4-pin connector. This selection covers the motherboard, processor, multiple drives and legacy peripherals found in the target HP models. No additional adapters or software are bundled with the power supply. Buyers needing more SATA ports or modern GPU power connectors should verify requirements before purchase.

Questions about this item

How do I install the ATX 24 (20+4) pin and P4 4-pin connectors, and what step is often missed?

Plug the 24-pin ATX and 4-pin P4 connectors firmly until they click; the step often missed is switching the 115/230 V input selector to match local mains voltage.

What maintenance will this unit need later?

Clean the single intake fan and vent openings periodically to prevent dust build-up that reduces airflow and cooling.

What limit appears first under sustained load?

The hold-up time of 17 ms minimum at nominal input is the first limit; if mains drops longer the outputs will lose regulation.
