Replacement ATX Power Supply

This Gulfe ATX unit is built as a direct replacement for legacy Dell power supplies such as the H300NM-0005DDV0, J517T and K159T. It fits systems that require a reduced-depth chassis design while delivering standard ATX output rails. The supply is new and weighs 2.5 kg.

Reduced Depth Compatibility

The chassis measures 5.9 inches in depth and 3.4 inches in width, allowing installation in tight enclosures where full-size units cannot fit. It accepts 115 or 230 V AC input across 47 to 63 Hz and provides hold-up time of 17 ms at nominal load. Over-current and over-power protection circuits are included.

Bundled Connector Set

A single 24-pin ATX connector, one 4-pin P4 12 V connector, three SATA power connectors, two LP4 connectors and one floppy connector are provided. This assortment covers motherboard, CPU, drive and legacy peripheral power needs without requiring additional adapters.

Questions about this item

What does the 300 W rating mean when the unit is installed in a real system?

It indicates the maximum combined continuous output the supply can deliver across all rails while staying within its 17 ms hold-up time and 70 ms rise-time limits.

How does the ATX 24-pin interface limit what this supply can power?

The single 20+4 pin connector and one 4-pin P4-12V plug restrict the unit to motherboards that use the standard ATX main power and a single 12 V CPU header.

Will the 5.9 in depth fit my Dell chassis that originally used the H300NM-0005DDV0?

Yes — the reduced 5.86 in depth matches the legacy Dell form factor, and the 3.4 in width aligns with standard ATX mounting holes.
