Replacement for Compaq Presario systems

This 420W ATX unit is built as a direct replacement for Compaq Presario SR1922X, SR1923WM, SR1924NX, SR2005LA and SR2006NX desktops. It accepts 115 / 230 V input and fits the reduced-depth chassis used by those models. The grey housing weighs 2.5 kg and includes a single cooling fan. Builders who need a higher wattage or a different form factor will not be served by this supply.

Sustained load behaviour

Over-current, over-power and over-voltage protection circuits guard the rails during continuous operation. The 80mm fan draws heat from the compact 5.9" by 3.4" enclosure to keep temperatures stable under prolonged load. No efficiency rating or hold-up time is provided in the data.

Installation and common issues

The bundle includes a 20+4 pin ATX connector, a 12V ATX connector, one SATA lead, two large peripheral leads at 15 inches, two more at 6 inches and one small peripheral lead at 6 inches. The 20+4 pin plug supports both 20-pin and 24-pin motherboards. Installers must verify that the reduced depth matches the case cavity and that the fixed cable lengths reach every device.

Perguntas sobre este artigo

How loud does the 80 mm fan get when the 420 W unit runs continuously?

The single 80 mm fan spins up only when internal temperature rises; under typical desktop loads it stays at a low, steady hum.

Which motherboard connector do I need on my board for the 20+4 pin ATX plug to fit?

The 20+4 pin ATX connector works with both 20-pin and 24-pin motherboard sockets, so either standard ATX layout will accept it.

Will the 15-inch SATA lead reach a drive bay in a full-height Compaq Presario SR1922X chassis?

Yes, the 15-inch SATA cable is long enough for the drive positions in the SR1922X and the other listed Presario models.
