Replacement for Wintech WIN-400PS

This 400 W ATX power supply is a direct replacement for the Wintech WIN-400PS unit. It fits standard ATX cases and supports both 20-pin and 24-pin motherboards via the included 20+4 pin connector. The unit is aimed at users repairing older desktops or building basic systems that require reliable power delivery.

400 W capacity and connector headroom

The supply delivers 400 W total output with a single cooling fan. It provides one 24-pin ATX connector, one 4-pin P4 12 V connector, three SATA 15-pin connectors, two Molex 4-pin connectors and one floppy 4-pin connector. This covers a typical motherboard, CPU power, multiple drives and legacy peripherals. Systems needing more than three SATA devices or additional PCIe power will exceed the available leads.

Bundled connectors enable legacy and modern drives

The included cable set adds three SATA power plugs for current hard drives or SSDs, two Molex plugs for older devices and a floppy connector for very old hardware. The 20+4 pin motherboard cable works with both 20-pin and 24-pin boards, while the 4-pin P4 connector supplies dedicated CPU power. No modular cables or software utilities are included.

Questions about this item

Will the 20+4 pin ATX connector on this RPSU-C95-1 work with my older 20-pin motherboard?

Yes, the 20+4 pin ATX connector splits so the extra four pins can be left disconnected, making it compatible with both 20-pin and 24-pin motherboards.

How can I verify the RPSU-C95-1 is running correctly after I install it?

The single fan should spin up immediately on power-on and the system should POST without unexpected shutdowns, indicating the 400 W output and protection circuits are functioning.

Which cables come attached to the RPSU-C95-1 and what must I source separately?

The unit ships with a fixed 20+4 pin ATX, one 4-pin P4-12V, three SATA 15-pin, two Molex 4-pin and one floppy 4-pin connector; no modular cables are included so any additional adapters must be bought separately.
