Replacement power supply for HP desktops

This unit replaces the original PSU in HP A1400y CTO and A1410 series desktops. It fits a standard ATX slot but uses a reduced depth of 5.86 inches for tighter chassis. An 80 mm fan provides cooling for stable long-term operation. The grey enclosure matches the OEM aesthetic.

ATX connector limits and cable complement

The 24-pin (20+4) motherboard connector and a 4-pin CPU connector power the board. Three SATA 15-pin leads serve drives, while two Molex 4-pin and one floppy 4-pin connector handle legacy devices. All cables are fixed, so unused leads must be tucked inside the case.

Continuous 280 W with 420 W peak headroom

The supply delivers 280 W total continuous power across +3.3 V, +5 V, dual +12 V rails, -12 V and +5 V standby. A 420 W peak rating covers brief load spikes. Hold-up time is 17 ms minimum at nominal input, and rise time stays under 70 ms. AC input accepts 110/220 V at 47–63 Hz.
