SKU CH-58ZA-WR7H7

180W server power supply with 7-pin and dual 4-pin connectors for ProDesk SFF systems

  • 180W output powers compatible ProDesk SFF systems
  • 7Pin + 4Pin + 4Pin connector fits specified motherboards
  • 100-240V input supports worldwide mains voltage
  • 85 × 52 × 200 mm form factor suits small chassis
  • New condition ensures full rated performance

Compatible ProDesk SFF Replacement

This 180 W server power supply replaces the PA-1181-3HB unit in ProDesk 280, 600 and 800 G3 as well as 400 G5 small-form-factor desktops. It accepts 100-240 V input at 2.3 A and 50-60 Hz for worldwide mains compatibility.

Fixed Cable Harness

The unit ships with a non-modular 7-pin plus dual 4-pin connector set that matches the motherboard headers of the listed ProDesk models. No extra cables or adapters are included, so installation is a direct swap without additional parts.

Suits G3 and G5 SFF Owners

This supply fits the exact chassis and pin-out of the named ProDesk SFF systems. Builders using full-size towers, different generations or boards requiring 24-pin ATX or PCIe power connectors should look elsewhere.

Questions about this item

Will the 7Pin + 4Pin + 4Pin connector set need replacing if the motherboard header layout changes in a future upgrade?

The connector set is fixed to the 7Pin + 4Pin + 4Pin layout used by the listed ProDesk SFF models; a different motherboard header would require a different power supply.

What limits continuous output before the 180W rating is reached under sustained load?

The 180W maximum power rating is the hard limit; sustained draw at or above that level will trigger protection or shutdown.

How much heat and fan noise should I expect when the unit runs all day at typical office loads?

With a 100-240V 2.3A input and compact 85*52*200mm chassis, the supply is designed for SFF airflow; expect modest warmth and low fan noise at typical loads well below 180W.
