Dell 275W replacement PSU

This Dell N275P-00 power supply delivers 275W for compatible Optiplex and Dimension systems. It matches the original part for small form factor chassis such as the Optiplex 740, 745, 755, GX520 and GX620. The unit also fits Dimension 5100c, 5150c and XPS 200, 210 models. It is supplied new with a 90 day warranty.

Steady 275W output under load

The supply is rated for continuous 275W operation rather than a short burst peak. It maintains stable rails during typical office workloads and integrated graphics use. The design targets the thermal envelope of the listed SFF cases. Sustained loads near the maximum rating should be paired with adequate case airflow.

Verify chassis and connector fit

Confirm your system appears in the supported model list before ordering. Check that the physical dimensions and mounting holes match the original unit in your chassis. Ensure the main power and any peripheral connectors correspond to your motherboard layout. This PSU is not suitable for standard ATX towers or proprietary servers outside the listed range.
