The Athena AP-MP4ATX20B 200 Watt Power Supply is an sfx form factor. This power supply is a good replacement for many Gateway and Compaq small form factor power supplies. What is so great about the AP-MP4ATX20B is that it is a full 200 watts and typically has more power than is ordinarily found in Gateway and Compaq power supplies of the same physical size. This power supply has the hard to find -5V lead and the 4-pin HP video connector.
This Athena 300 watt micro atx power supply model MP4ATX30 is not only powerful, but it is also compatible with a wide range of HP computers. The reason for this is because the MP4ATX30 has an integrated HP video power that enables the power supply to provide power to the video card through the HP motherboard.
The Athena Apollo 400 watt micro atx power supply model AP-MP4ATX40 has lots of power at great affordability. What is really great about this power supply is that it is backward compatible with many older systems where the -5V circuit is required and video is powered directly from the power supply to the motherboard.
