Item Condition Brand new
Remarks -High quality Standard AT 350 Watt power supply unit with white wire -5Volt rail. Suitable for older ATX computers with ISA Bus. Optional P10 6pin connector. -Used in legacy computers using AT technology, HDD Storage enclosure, Shopping mall kiosks, Amusement industry. (Gaming machines, Video games, Arcade games), Legacy industrial control platform, Plant control system and more... -P8 and P9 connectors MUST be plugged in so that the black wires are side by side (together in the center). Failure to do so may damage the board. -Some systems without motherboard do not require the P8 & P9 connectors which can be left unused. -Some systems do not require the On/Off switch which can simply be left switched ON and tied up safely inside the machine. The switch is also removable and can be replaced by another one (terminal block size: 9x0.6mm). -AT PSUs traditionally have a Monitor Outlet but a standard PC/Kettle power cord can be used to power the monitor directly from the Mains instead. You can use a twin power cord to minimize cabling. -This PSU comes with a fan on top, which may not be suitable for slim chassis such as a 2U rackmount where the lid will obstruct the air flow. See alternative PSU in our shop if required.
