Replacement PSU for Compaq Presario

This 420W ATX unit is a direct replacement for Compaq Presario SR5035KR, SR5050NX, SR5102HM, SR5130NX and SR5152NX desktops. It fits the original mounting points and connector layout without modification. The grey enclosure uses a single 80mm fan for cooling. It suits owners restoring or upgrading these specific legacy systems.

Capacity and headroom

The supply delivers 420W through a switchable 110V or 220V input. Connectors include one SATA lead, a 20+4 pin ATX lead, a dedicated 12V ATX lead, two large peripheral leads and one small peripheral lead. This complement covers the drives and motherboard in the target chassis. Builds needing multiple SATA devices or PCIe power will run out of native connectors.

20+4 pin ATX and fixed cable lengths

The motherboard cable supports both 20-pin and 24-pin headers in a single 14-inch reach. The 12V ATX cable is also 14 inches. SATA and large peripheral cables are 15 inches; the shorter large and small peripheral cables are 6 inches. Verify these lengths suit your case routing before purchase.
