Original Power Supply Board for HP LaserJet Pro M403dn / M403dw — Imported

Get your HP LaserJet Pro M403 back to life with the PRM Original Power Supply Board. This is a genuine original board — not a compatible copy — sourced from original equipment and imported directly. One board fits both the M403dn and M403dw.

Looking for an HP M403dn power supply or HP M403dw power board? This is the correct power supply board for both printers.

When Do You Need a New Power Supply Board?
The power supply board converts mains AC power into the regulated DC voltages that run every component inside your printer — the formatter, fuser, motor, and WiFi module. When it fails, the entire printer is affected. Replace your power supply when you see:
- Printer completely dead — no lights, no display, no response when pressing the power button
- Printer turns on briefly then shuts off immediately
- Random shutdowns during printing — printer dies mid-job
- Fuser error or 50.x error — the power supply feeds the fuser heater; a weak supply causes temperature errors
- Burning smell from the power supply area (not from the fuser)
- Printer takes unusually long to warm up or never reaches ready state
- Display panel freezes, goes blank, or flickers during printing
- WiFi module not powering on — printer drops off the wireless network (M403dw)
- Ethernet/network connection dropping intermittently (M403dn)
- Tripping your office power switch when the printer turns on

If you've checked the power cable, tried a different wall socket, and the printer still won't power on or keeps shutting down — the power supply board is almost certainly the cause.

1. Fits Both M403dn and M403dw: One power supply board works across both the HP LaserJet Pro M403dn (Ethernet) and M403dw (WiFi). Same board, same connectors — works in either model.

2. Original, Not Compatible: This is a genuine original HP power supply board — the same board that came inside your printer from the factory. Original boards offer exact voltage regulation and long-term reliability that compatible copies cannot match. For a critical component like the power supply that feeds every part of your printer, original is the right choice.

3. Fixes the "Dead Printer" Problem: The most common power supply failure symptom is a completely dead printer — no lights, no response. The M403 is a 38 pages per minute workgroup printer built for heavy office use. Before you replace this capable machine, a power supply board swap brings it back to life at a fraction of the cost.

4. Resolves Fuser Errors Without Replacing the Fuser: Many fuser errors on the M403 are actually power supply problems — the board can't deliver enough power to heat the fuser properly. If you've already replaced the fuser and still get temperature errors, the power supply is the fix.

5. Restores Duplex, WiFi, and Network: The M403dn supports Ethernet and automatic two-sided printing. The M403dw adds WiFi. All of these features demand stable power — a failing supply often shows symptoms during duplex jobs first or causes network/WiFi to drop. A new board restores stable operation across all features.

6. Easy Installation: Disconnect the printer from mains power, remove the side/rear panels, unplug the connectors from the old power supply board, swap in the new one, reconnect all cables, and reassemble. 20-30 minutes for any printer technician. Basic screwdriver needed.

7. Tested Before Shipping: Every PRM power supply board is tested for correct voltage output before dispatch. Backed by our testing warranty.
