F.A.Q - Frequently asked Questions
I was wondering if this item can be used as a DIRECT (the cables just plugs in/fits straight in with no hassles) replacement for a HP Part Number 667893-003 Power Supply?
Yes, this power supply will fit your HP Part Number 667893-003 perfectly. This will be the same size and dimensions, also this will have all the correct connectors that you need and more.

This replacement unit says it is 400 watts, that is higher than what is currently in my computer, are you sure this will work?
The 400 watts is a maximum output. This will work perfectly with your application. Think of it as extra power if it is needed. Otherwise it just uses the amount it needs. 

The values listed for output current are higher than on the original. I am assuming that this is not a problem as these values are only what it is capable of delivering, but I just wanted to make sure that this unit is definitely compatible despite the differing values.
Yes, This will work perfectly as a replacement and upgrade for your HP Part Number 667893-003, this is designed to work perfect as a replacement for your unit. This is also an upgrade as it is a higher wattage; which can handle more devices: hard drives, dvd-roms, Ram or CPU if you choose to add them. 
This power supply also adds higher efficiency and a low noise fan. Further, this power supply is newly manufactured with newer components internally as well as over voltage protection, over power protection, short circuit protection, low noise and ripple fan, Energy star efficient.
That's why this exceeds getting an exact replacement that was most likely manufactured years ago with older parts/technology; and capacitors go bad over time, even when not is use. Plus this comes with a one year manufacture warranty.
