Replacement ATX Power Supply

This Gulfe ATX unit is built as a direct replacement for the HP Pavilion W351GF3 500-314 a1528x desktop. It uses a reduced-depth form factor measuring 5.9 inches in height and 3.4 inches in width to fit the original chassis. The supply weighs 2.5 units and includes a single cooling fan. It delivers the standard ATX voltage rails including +5V, -5V, +12V1, +12V2, +3.3V, -12V, and +5V-SB.

Connectivity and Protection Fit

The cable set provides one 24-pin ATX connector, one 4-pin P4-12V connector, three SATA power connectors, two LP4 connectors, and one floppy connector. This suits owners of the listed HP models who need to restore power to legacy SATA drives and older peripherals. Builders requiring modern PCIe power cables for discrete graphics cards or additional SATA ports beyond three should look elsewhere. The unit includes over-current and over-power protection circuits.

Sustained Operation Characteristics

The power supply accepts a wide AC input range of 115 to 230 volts at 47 to 63 hertz. It achieves a rise time of less than 70 milliseconds and guarantees a minimum hold-up time of 17 milliseconds at nominal load. Hi-pot testing and low ripple and noise specifications support stable output during continuous operation. Efficiency is rated as high by the manufacturer for this class of replacement unit.
