Genuine HP/Compaq 340W Replacement PSU

This genuine HP/Compaq 349774-001 power supply delivers 340W maximum output for compatible Business desktop systems. It supports DC7100 Convertible Minitower, DX6120 Microtower and DX6100 Microtower chassis. The unit accepts 100-240V input at 50-60 Hz for worldwide voltage compatibility. It replaces part numbers 349774-001 and 349987-001 directly.

Standard ATX connector layout simplifies

The PSU provides a 24-pin motherboard connector, a 4-pin motherboard connector, three 4-pin Molex connectors, one 4-pin floppy connector and four Sata connectors. Installation follows typical minitower procedure: remove the side panel, unplug the old unit, swap cables and secure the new PSU with the original screws. The fixed cable lengths suit the listed chassis; builders using non-listed cases may find the 24-pin or 4-pin leads too short for bottom-mount layouts.

340W maximum output defines the power budget

This single rating determines whether the unit can support your CPU, graphics card and drive complement. The 340W peak covers the original system configurations; adding high-wattage GPUs or many drives will exceed the available headroom. Verify your total component draw against the 340W limit before purchasing.

Questions about this item

How can I confirm the 340W PSU is working after installing it in my DC7100?

Power on the system and verify the fan spins, the front power LED stays solid, and the BIOS reports stable +12 V and +5 V rails under load.

What cables come attached to the 349774-001 and what must I source separately?

The unit has a fixed 24-pin motherboard connector, a 4-pin motherboard connector, three 4-pin Molex, one 4-pin floppy, and four Sata connectors; no modular cables are included.

Should I choose the 349774-001 or the 349987-001 for a DX6120 Microtower?

Both part numbers are listed as compatible with the DX6120 Microtower and share the same PS-5341-4CF model, so either will fit and deliver 340 W.
