Circa 1988; the AT Power Supply has been around for 23 years and it is still going strong in today’s industry.  It is used to power equipment from the smallest robotic drill to essential medical equipment.  Athena Computer Power understands the importance of these Power Supplies and has boosted the wattage up to 300; supplying more power while maintaining reliability and control.  The 300 Watt AT power supply is a great selection for many industrial machines.   It is a stable power source that gives machines more wattage to run on.  The AT Power Supply functions differently than its younger counterpart the ATX, by being able to power on manually with a power switch, having this type of control is necessary for the safety of heavy or delicate machinery that interacts together.  This AT power supply is compatible with many older model systems such as accounting systems, automatic control machines, and storage PCs for power supply replacement.
