350 W SFX replacement power supply

This 350 W SFX unit replaces Enhance ENP-1211J, ENP-2120A and ENP-2725A power supplies in compatible small-form-factor PCs. It delivers a 20+4 pin motherboard connector, a 4-pin CPU connector, Molex, floppy, SATA and a 6+2 pin PCIe connector for graphics cards. The AT-type design suits older Gateway and Compaq systems as well as newer custom builds needing an SFX footprint.

Check connector fit and case clearance

Verify that your motherboard accepts the 20+4 pin main connector and the 4-pin CPU power plug before ordering. Ensure the chassis has an SFX mounting aperture and enough depth for the 80 mm fan assembly. Confirm that the 6+2 pin PCIe lead reaches your graphics card and that SATA power cables match your drive count. The unit uses an AT power-on signal, so the motherboard must support that standard.

Thermals noise and power draw

An 80 mm double-ball-bearing fan exhausts heat from the compact housing under load. Acoustic output rises with fan speed when the supply approaches its 350 W rating. At typical desktop loads the fan runs at lower RPM, keeping noise modest for an SFX design. The unit draws AC power proportional to system demand plus its own conversion losses.

Questions about this item

Does the box include every cable needed for a typical SFX build, or must I buy extra connectors?

The unit ships with a 20+4 pin motherboard cable, a 4-pin CPU cable, Molex, floppy, SATA and a 6+2 pin PCIe connector, covering most small-form-factor builds without extra purchases.

Which of the listed Enhance models — ENP-1211J, ENP-2120A or ENP-2725A — should I match to my existing PSU?

Choose the model printed on your current Enhance label; this replacement is validated for all three part numbers.

What does the 350 W rating mean when the supply is installed in a compact Gateway or Compaq chassis?

It delivers up to 350 W continuous through an 80 mm double-ball-bearing fan, keeping the 12 V rail stable inside tight SFX cases.
