TFX 350W Replacement for Dell Liteon PS-5251-5

This TFX form-factor power supply delivers 350W output and is built to replace the Dell Liteon PS-5251-5 unit in compatible small-form-factor desktops. It accepts 100-240V input and uses an 80mm double ball-bearing fan for cooling. The unit suits owners of supported Dell SFF systems who need a direct swap for a failed or ageing PSU.

Verify Case Space and Connector Needs

Confirm your chassis accepts the TFX form factor and that your motherboard uses a 20+4 pin main connector plus a 4-pin CPU power plug. The supply also provides two Molex, one floppy and two SATA connectors for drives and peripherals. Ensure the total system draw stays within the 350W rating before ordering.

Included Cables Cover Legacy and Current Drives

The fixed cable harness supplies two SATA power plugs for modern SSDs or hard drives alongside two Molex and one floppy connector for older devices. This mix lets you power a typical SFF complement of storage and optical drives without adapters. No modular cables or extra accessories are bundled with the unit.
