Is Your HP Desktop Having Power Issues? Here‘s Your 300W Replacement & Upgrade Guide
If you own an HP desktop such as the 280 Pro G2, Pro 3330/3340/3380, or ProDesk 550/405 G2/400 G3 and are experiencing power failures, random shutdowns, or simply want to upgrade from a lower-wattage power supply, you’ve come to the right place.
This 300W power supply is unique because it is backward compatible with lower-wattage units that have the same interface and physical size. This means you can upgrade your older 180W HP power supply to this more powerful 300W unit for better system stability and future upgrade headroom.
This guide will help you quickly identify if the 300W PCB230 Power Supply is the right match for your HP computer.

Special Technology Note:
Solid-state purification technology – The output current is purer, providing cleaner power to your computer components. This results in better system stability, reduced electrical noise, and longer component life.
Upgrade Compatibility Note:
The high-power power supply is compatible with low-power power supplies of the same interface and appearance size.
If your current HP desktop has a 180W power supply (such as D13-180P1A, HK280-11FP, DPS-180AB-20 A, PCE018, D14-180P1A, or PCD009), you can upgrade to this 300W unit for:
- More power headroom for additional components
- Better stability under load
- Future upgrade capability
Physical Size – Measure Before You Order
Even if the model number matches, it‘s always a good idea to check the size.
| Dimension | Measurement |
| Length | 150 mm |
| Width | 140 mm |
| Height | 85 mm |
This standard desktop size is designed for HP MT (Mini Tower) and large chassis desktops.
Installation Tips
- Power down and unplug your HP desktop completely.
- Open the case – HP MT cases typically have thumbscrews on the back.
- Disconnect cables from the old power supply – note where each connector goes.
- Check your interface type – determine if you need Type 1 (4 SATA) or Type 2 (2 SATA + floppy).
- Take a photo of the connector layout before disconnecting.
- Remove the old PSU – usually held by 3-4 screws on the back of the case.
- Install the new PSU – secure with screws, then reconnect all cables.
- Test before closing – power on to ensure the system boots properly.
