Replacement PSU for HP Desktops

This myVolts power supply replaces the original units in HP A1700 A1705 A1710 and A1712 desktop models. It delivers up to 420 Watts maximum and 280 Watts total continuous power. The AT form factor fits a standard ATX slot with reduced depth for tighter chassis clearance.

420 Watt Peak with 280 Watt Continuous Rating

The single figure that decides compatibility is the 280 Watt total continuous output across +5 V -5 V +12 V1 +12 V2 +3.3 V -12 V and +5 V standby rails. If the original HP unit was rated higher than 280 Watts continuous this replacement may not sustain full system load.

Suits Direct HP Swaps Not High Power Builds

This unit suits owners of the listed HP desktops who need a like-for-like new replacement with 20+4 pin motherboard 4 pin CPU three SATA two Molex and one floppy connector. Builders needing more than 280 Watts continuous or modular cabling should look at higher rated ATX power supplies.

Questions about this item

What does the 420 W maximum mean once the unit is installed?

The 420 W figure is the peak output the supply can deliver for short periods; continuous combined output across all rails is rated at 280 W, so sustained loads should stay within that lower total.

Which interface standard governs the drive power connectors and what does it limit?

The three SATA 15-pin connectors follow the SATA power specification, limiting each drive connector to the standard 3.3 V, 5 V and 12 V rails defined by that interface.

What physical space is needed to mount this supply in a case?

The unit measures 5.86" by 3.3" with reduced depth, so it fits a standard ATX mounting cut-out while leaving extra clearance behind the rear panel.
