Replacement ATX Supply for HP Desktops

This Replace Power unit delivers 420 watts maximum and 280 watts total continuous power in a reduced-depth ATX form factor. It fits HP A650e, A650y, A656x, A700n, A700y, A705w, A706n and A708n models using an 80 mm fan for cooling. The grey chassis measures 5.86 inches deep for tighter case clearance.

Suits direct HP chassis swaps only

Builders restoring the listed HP desktops will find the native 24-pin, 4-pin CPU, three SATA, two Molex and one floppy connector match the original wiring. Systems needing PCIe power cables, higher continuous wattage or modular cabling should look at a different supply.

280-watt continuous rating decides fit

The total continuous output of 280 watts is the figure that determines whether this unit can sustain your components under load. Verify your system draw against that number before purchasing.

Questions about this item

How loud or hot does the 80 mm fan get when the Replace Power 420 W unit runs all day?

The supply uses a single 80 mm fan and is described as low ripple and noise, with a hold-up time of 17 ms minimum at nominal input voltage.

What existing cables or connectors must my HP desktop already have for this ATX replacement to work?

Your motherboard needs a 24 (20+4) pin ATX socket and a 4-pin CPU power socket; drives need SATA 15-pin, Molex 4-pin or floppy 4-pin connectors.

Will the reduced-depth 5.86-inch chassis fit alongside the original mounting brackets in an HP A650e or A700n?

Dimensions are 5.86" x 3.3" x 4", so the shorter depth increases compatibility with standard ATX slots in those HP models.
