Gulfe ATX Power Supply for HP Pavilion P7-1430BR p7-1490

Target System Compatibility

This ATX power supply is built as a direct replacement for HP Pavilion P7-1430BR and p7-1490 desktop computers. The reduced depth form factor improves fit inside compact OEM chassis where standard units may not clear internal components. It delivers the necessary +5V, -5V, +12V1, +12V2, +3.3V, -12V and +5V-SB rails through native connectors including a 24-pin ATX, 4-pin P4, three SATA, two LP4 and one floppy plug. The unit weighs 2.5 units and measures 5.9 inches by 3.4 inches.

Thermals, Noise and Power Draw

A single fan provides active cooling across the 115/230 V input range and 47-63 Hz frequency band. The supply is hi-pot tested and specified for low ripple and noise during operation. Protective circuits include over-current and over-power shutdown to protect connected hardware. Rise time is rated under 70 ms with a minimum hold-up time of 17 ms at nominal load, supporting stable voltage delivery during brief mains interruptions. High efficiency is claimed by the manufacturer.

Upgrade Context and Limits

This unit replaces several older legacy power supplies used in the listed HP Pavilion models. It restores reliable power when the original unit has failed or become unstable. The connector set covers the motherboard, CPU, SATA drives, legacy LP4 peripherals and a floppy drive if present. It is not suitable for systems requiring additional PCIe power connectors, higher total wattage than the original design, or modern 12VHPWR graphics cards. Builders needing modular cabling or silent fanless operation should look elsewhere.
