SKU CH-QTZZ-4P6XT

  • Delivers 240 W for stable ProDesk operation
  • Tested for full functionality before shipment

  • Includes 6-pin PCIe, floppy and 4-pin 12 V connectors
  • Single fan with heatsink provides reliable cooling

240W SFF Power Supply

This 240W small form factor power supply fits HP ProDesk 400 G1, 600 G1 and EliteDesk 800 G1 desktops. It provides a 6-pin PCI Express connector, a 4-pin 12V connector and a floppy drive connector for internal components. The non-modular design keeps cabling simple inside the compact chassis.

Sustained 240W Delivery

A single fan with heatsink cools the unit while it supplies up to 240W continuously. The fixed cable set means no extra connectors to manage during long work sessions. Stable output supports typical office workloads and integrated graphics without unexpected shutdowns.

Replaces G1 SFF Units

This unit replaces a failed or noisy original supply in the listed G1 small form factor models. The jump is worth it when the existing PSU no longer holds voltage under load or the fan has become audible. Builders needing higher wattage or modular cables for discrete graphics upgrades should look elsewhere.

Questions about this item

How loud or hot does the 240W unit with its single fan get when running continuously in an HP ProDesk 400 G1?

The supply uses one fan and heatsink for cooling; noise and heat under constant load depend on the chassis airflow of the specific ProDesk 400, 600 or 800 G1 SFF it is installed in.

Which cables or adapters must I already have to connect the 6-pin PCI Express, floppy and 4-pin 12V plugs on this PSU?

The unit is non-modular, so the 6-pin PCIe, floppy and 4-pin 12V leads are fixed; you only need motherboard and drive sockets that match those connectors.

Will this 240W SFF supply fit and power an older HP ProDesk 400 G1 chassis without modification?

Yes, the part numbers 722536-001, 702455-001, 751884-001 and 702457-001 are listed as compatible with ProDesk 400 G1, 600 G1 and EliteDesk 800 G1 small form factor models.
