PS2 350W power supply. Athena Computer Power AP-P4ATX35 350W Power Supplies Computer Parts Athena Computer Power is pleased to present their new Entry level power supply for the PS2 form factor. The EXTREME series starts off at 350 Watts of true power. With its compact and light features this PSU is perfect for replacement power. Multiple Support Function The EXTREME 350 Watt power supply is for new OEM, PC, server assemblies, MiniServers, and rackmount servers. This power supply is for new system assembly and compatible with many older model systems, Accounting systems, and for power supply replacement. (OEM only) Dual Fan With its dual fan features located at the front and back of the power supply, the rear fan intakes the heat that is produced inside the server or system and pushes it through the front fan. This design allows the power supply to be able to take 100% of the heat that is generated by the interior system and pushes it out of the server/system. While some other PSU fans work differently, this dual fan design is targeted to maintain a reliable source of power and keeping the system cool. Some may second guess this dual fan feature because it will increase noise volumes, but with its thermal fan speed control it will detect the amount of heat generated by the computer and spin accordingly. Smart Auto Fan Speed Controller Thermal fan speed control will detect the amount of heat generated by the computer.
