HP 633190-001 Power Supply 300W
The HP 633190-001 power supply is a key identification reference for this 300W PSU.
Customers searching for an HP replacement PSU may encounter several different part numbers and descriptions for similar-looking power supplies. Using 633190-001 together with the computer model can make identification easier.
The 300W rating indicates the PSU’s power capacity, but compatibility also depends on the computer’s electrical design and physical configuration.
For that reason, we recommend checking the original unit before purchasing.
HP 667892-001 Power Supply
The 667892-001 part number is another important reference associated with this HP 300W power supply.
When searching for an HP Pro 3400 3330 3380 3500 MT PSU, customers may use either 633190-001 or 667892-001 as a search term.
Using both numbers can be particularly helpful when comparing replacement listings.
The most reliable method remains matching the information printed on the original power supply with the replacement being purchased.
HP Pro 3400 MT Power Supply
The HP Pro 3400 MT is a Microtower desktop configuration, and the 300W PSU provides power for compatible system components.
A suitable replacement can help restore a Pro 3400 when the original PSU has failed.
Before replacing the unit, we recommend confirming:
- The computer is the HP Pro 3400 MT.
- The original PSU is rated at 300W.
- The PSU carries a compatible HP part number.
- The connectors correspond with the computer.
- The replacement physically fits the chassis.
HP Pro 3330 MT Power Supply
The HP Pro 3330 MT is another compatible system referenced when searching for this family of HP power supplies.
If replacing the PSU in an HP Pro 3330 Microtower, check the original unit carefully rather than assuming that every Pro 3330 configuration uses an identical PSU.
The 633190-001 and 667892-001 numbers provide useful references when looking for a replacement.
HP Pro 3380 MT Power Supply
The HP Pro 3380 MT power supply is another search term customers can use when looking for a compatible 300W replacement.
As with other HP Pro desktop systems, the exact configuration should be verified before ordering.
Matching the original PSU’s part number and connectors is particularly useful when replacing an OEM power supply.
HP Pro 3500 MT Power Supply
The HP Pro 3500 MT power supply is also associated with this 300W replacement PSU category.
The Microtower designation is important because HP produced computers in several different chassis sizes. A Microtower PSU should not automatically be assumed to fit an SFF or other compact configuration.
When purchasing, we recommend using the complete product description:
HP Pro 3500 MT 300W Power Supply 633190-001 / 667892-001
This provides several useful identification points in a single search.

The original PSU label should always be checked for the exact model and electrical specifications before purchasing.
HP 300W Microtower PSU Compatibility
Compatibility is one of the most important factors when selecting an HP 300W Microtower power supply.
Two power supplies can both be rated at 300W but still have different:
- Connectors
- Dimensions
- Mounting points
- Cable configurations
- Electrical specifications
Therefore, a generic 300W PSU should not automatically be considered a replacement.
The 633190-001 and 667892-001 identifiers are particularly useful when trying to match the original HP unit.
How to Identify the HP 633190-001 PSU
The easiest way to identify the PSU is to inspect its label.
Look for:
HP Part Number: 633190-001
Alternate Part Number: 667892-001
Power Rating: 300W
Manufacturer: Check the PSU label.
Model: Record the manufacturer’s model number.
If these details correspond to the original unit, they provide a strong starting point for identifying a replacement.
HP Pro 3400 3330 3380 3500 MT PSU Replacement
Replacing a failed PSU can be an effective way to restore an older HP business desktop.
A power supply replacement may be appropriate when:
- The computer does not turn on.
- The PC shuts down unexpectedly.
- Power is intermittent.
- The system becomes unstable.
- The PSU has been diagnosed as faulty.
These symptoms can have multiple causes, so proper troubleshooting is recommended before replacing the PSU.
Once the power supply has been confirmed as defective, a compatible 300W replacement PSU can help restore the computer.
300W HP Pro Power Supply for Business Desktop Repair
HP Pro desktop systems are commonly used in business and office environments.
A replacement PSU can be useful for companies, technicians, schools, refurbishers, and IT departments maintaining older HP computers.
Instead of replacing an entire computer because of a failed PSU, replacing the individual power supply may allow the remaining working hardware to continue being used.
This can be particularly useful when the computer is still suitable for its intended applications.
Replacing the HP Pro 3400 3330 3380 3500 MT PSU
Before replacing an internal PSU, shut down the computer completely and disconnect the power cable.
We recommend documenting the existing cable connections before removing the original unit. A photograph can provide a useful reference during reassembly.
Remove the original PSU and install the replacement according to the computer’s chassis design.
Reconnect the required motherboard, processor, storage, and peripheral power connections.
Before powering the computer, check that all connections are properly seated.
If a connector does not match the original, do not force it. Confirm the replacement PSU’s compatibility first.
What to Check Before Buying 633190-001

Additional components such as:
- Dedicated graphics cards
- Additional hard drives
- SSDs
- Optical drives
- Expansion cards
can affect overall system power requirements.
The replacement PSU should therefore be appropriate for the complete computer configuration.
Why Match the HP PSU Part Number?
Matching the original HP part number is one of the simplest ways to reduce compatibility problems.
The 633190-001 and 667892-001 identifiers provide specific references rather than relying on a generic description such as “HP 300W PSU.”
When searching for a replacement, combining the part number with the computer model provides a more precise product search.
For example:
HP 633190-001 300W PSU
667892-001 300W Power Supply
HP Pr3400 MT 300W PSU
3330 MT Power Supply
