Reduced Depth ATX Power Supply

This Replace Power unit delivers up to 420 W peak and 280 W continuous power in a shortened ATX form factor. It is built as a direct replacement for HP A710m, A710n, A712n, A714x, A720n, A735w and A1010y CTO desktops. The compact depth helps it fit chassis where a standard-length PSU would foul internal components. A single 80 mm fan provides cooling for stable long-term operation.

Compatibility Check Before Ordering

Verify that your motherboard uses a 24-pin (20+4) ATX connector and a 4-pin CPU power header. Count the drives you plan to power: the harness includes three SATA 15-pin plugs, two Molex 4-pin plugs and one floppy 4-pin plug. Confirm the case can accept a grey unit measuring 5.86" x 3.3" x 4" and that the AC inlet matches your local 110 V or 220 V supply at 47–63 Hz. This supply is not for builders who need more connectors than listed or a higher continuous wattage rating.

Thermals Noise and Power Draw

The 80 mm fan runs at speeds that keep internal temperatures low while maintaining low ripple and noise output. At typical loads the unit draws up to 280 W total from the mains and holds output for at least 17 ms during brief input interruptions. Rise time stays under 70 ms, and the +12 V rails share the load with +5 V, +3.3 V, -12 V and +5 V standby rails. Hi-Pot testing, ROHS and CE marks confirm baseline safety compliance.

Perguntas sobre este artigo

What connectors come attached to the Replace Power 420W unit?

The supply ships with a fixed 24 (20+4) pin motherboard connector, a 4-pin CPU plug, three SATA 15-pin leads, two Molex 4-pin leads and one floppy 4-pin lead.

Should I pick the 420 W peak or the 280 W continuous rating for my HP desktop?

Use the 280 W total continuous figure for everyday loads; the 420 W peak is only for brief transients.

Will the 5.86 inch depth fit my HP A710m chassis?

Yes — the reduced 5.86" depth is designed to slide into standard ATX bays in HP A710m, A710n, A712n, A714x, A720n, A735w and A1010y models without protruding.
