Direct replacement for Dell Dimension 4600 4700

This 420W ATX power supply is built specifically for Dell Dimension 4600 and 4700 desktops. It matches the original form factor and connector layout so the unit fits without modification. The grey enclosure houses a single 80mm fan for cooling. It suits owners restoring or upgrading those legacy systems.

ATX layout with switchable input voltage

The unit uses a standard ATX design with a manual 110V/220V input selector for global mains compatibility. A 20+4 pin motherboard connector supports both 20-pin and 24-pin boards. One 12V ATX connector, two large peripheral connectors, two short large connectors, one small connector and a single SATA lead cover internal devices. Cable lengths are 14-inch for motherboard and 12V leads and 15-inch for SATA and large peripheral leads.

Ready to install with no extra parts required

All necessary power leads are permanently attached so there are no loose cables to route or misplace. The connector mix covers hard drives, optical drives and older floppy devices in one package. No software or driver installation is involved; the supply is purely a hardware swap. Buyers needing higher wattage for modern graphics cards or multiple drives should look elsewhere.
