Direct Replacement for Gateway Desktops

This Gulfe ATX power supply replaces legacy units in Gateway GT5026E, GT5220 and GT5456H systems. It delivers the standard output rails of +5V, -5V, +12V1, +12V2, +3.3V, -12V and +5V-SB. A single fan provides cooling within the reduced-depth chassis. The unit weighs 2.5 units.

Fits Tight Cases Where Standard ATX Units Bind

The reduced depth of 5.9 inches height by 3.4 inches width allows installation in compact Gateway chassis where full-length supplies cannot fit. It accepts 115 or 230 V input across 47 to 63 Hz. Over-current and over-power protection circuits guard connected components. Hold-up time is rated at 17 ms minimum.

Powers Legacy Drives and Motherboards

The harness includes a 24-pin ATX connector, a P4 4-pin CPU plug, three SATA 15-pin connectors, two LP4 4-pin plugs and one floppy 4-pin connector. This covers the motherboard, processor, multiple hard drives or optical drives and a legacy floppy device. No PCIe or EPS connectors are present for modern graphics cards or server boards.

Questions about this item

What are the exact dimensions of this ATX power supply so I can confirm it fits my Gateway case?

The unit measures 5.86 inches in length and 3.3 inches in width, with a reduced depth design for increased compatibility in Gateway GT5026E, GT5220 and GT5456H chassis.

How do I connect the 24-pin ATX connector correctly to avoid a no-post issue?

Align the 20+4 pin ATX connector with the motherboard keying; the 4-pin section only fits one way. Seat it firmly until the latch clicks, then attach the separate P4 4-pin 12V plug near the CPU socket.

When should I replace the single cooling fan inside this power supply?

Replace the fan if bearing noise appears or airflow drops noticeably; the 17 ms minimum hold-up time and over-current protection remain effective only while the fan maintains safe internal temperatures.
