Efficiency 70% Quad 12 V Separate Lines: MTBF 100,000 hours As processors become faster and more highly integrated, more current is required. To reduce power distribution loss, board manufactures are moving from 5V to 12V power distribution. Operating : 0 ~ 50˚C System components that use 12V are continuing to increase in power. Temperature (40 ~ 50˚C derating curve) Version 2.0 of Intel's ATX12V Power Supply Design Guide began recommending dual 12V Storage : -40 ~ 70˚C lines for PSUs that can deliver more than 18A at 12V. Why? To abide by safety requirements of UL and EM 60950, which stipulates not more than 240VA on any wires or exposed traces. Intel's PSU Guide calls for a current limiter that keeps current to under 20A on each of the 12V 140X 150 X 86 (mm) Dimensions rails: 12V x 20A = 240VA. 5.51 X 5.91 X 3.39 (inch) What is the safety reason for this 240VA maximum? It's the maximum recommended for an electronic device that a consumer will have reasonable likelihood of access. 20+4-pin ATX x1, 4-pin 12 V CPU x1, Output The +12V1 & +12V2 (1st. & 2nd +12V rails) supply the AUX12V (2x12V) 4-pin plug, which conntector HDD/CDROM x9, FDD x1, SATA x2 feeds only the CPUs. The +12V3 (3rd +12V rail) supplies the 24-pin ATX main power connector, which feeds for the Mother Board. The +12V4 (4th. +12V rail) supplies 4-pin Peripheral Power connector, which feeds for the I/O Ordering Information devices. The quad 12V rails provide more ţexible application, such as: Part No. Description RAID System – dedicated +12V rail for IO devices (HDDs) Server (multiple Processors) – Multiple dedicated +12 rails for Processors 600 W AC-DC PS/2 ATX power supply, with ACE-4860AP-R11-RS PFC ACE-4860AP-V21
