Replacement for HP 1350 1355 1357 1373 1383

This ATX power supply is built as a direct replacement for several HP desktop models including the A1350y A1355c A1357c A1373w and A1383w. It delivers a maximum output of 420 watts with a continuous rating of 280 watts. The unit suits owners of those systems who need a new PSU that matches the original form factor and connector layout.

Reduced depth ATX with fixed cabling

The housing measures 5.86 inches deep which is shorter than many standard ATX units so it fits tight chassis without protruding. A single 80mm fan provides airflow. Fixed cables include a 24 pin 20+4 motherboard connector a 4 pin CPU connector three SATA 15 pin connectors two Molex 4 pin connectors and one floppy 4 pin connector. The grey finish matches the original equipment aesthetic.

Low ripple noise and wide input range

The supply accepts AC input from 110 to 220 volts at 47 to 63 hertz and is Hi Pot tested with ROHS and CE compliance. Output rails cover +5V -5V +12V1 +12V2 +3.3V -12V and +5V standby. Rise time is under 70 milliseconds and hold up time is at least 17 milliseconds at nominal input. The design targets low ripple and noise for stable everyday operation.

Questions about this item

What does the 24-pin (20+4) ATX connector support on this Replace Power unit?

The 24-pin (20+4) ATX connector fits both 20-pin and 24-pin motherboard headers, delivering +3.3 V, +5 V, +12 V1, +12 V2, -12 V and +5 V standby rails up to the unit's 280 W total rating.

How much clearance does the reduced-depth chassis need inside an HP A1350y or A1383w case?

The supply measures 5.86 inches deep, 3.3 inches wide and 4 inches tall, so it fits standard ATX bays while leaving extra room behind the drive cage for cable routing.

Which cables are permanently attached and what is the first connector to seat during installation?

All leads are fixed: one 24-pin (20+4) motherboard, one 4-pin CPU, three SATA 15-pin, two Molex 4-pin and one floppy 4-pin. Seat the 24-pin motherboard connector fully before plugging in the 4-pin CPU lead.
