KHACHIMO Power Supply 300W ATX for Antec P8 P9 PP-300V SPI-300G

300W ATX replacement for Antec P8 and P9

This 300-watt ATX power supply is built as a direct replacement for Antec P8 and P9 chassis that originally used the PP-300V or SPI-300G units. It is intended for owners of those compact desktops who need a tested, working unit to restore power delivery. The supply fits the standard ATX form factor used in the original systems. It suits users replacing a failed or ageing PSU in the supported Antec models.

Limited to 300 watts on the ATX interface

The 300-watt rating restricts this supply to low-power configurations such as office PCs or basic home systems with integrated graphics. Builders planning to add a discrete graphics card, multiple drives or high-wattage CPUs will exceed the available headroom. The ATX connector set matches the original Antec wiring, so adapters are not required for the supported cases. Systems needing more than 300 watts must use a higher-capacity unit.
