Compare to APW3++ 93.5% conversion effeciency , APW7 PSU is 95% conversion efficiency, which mean APW7 save more electricity fee,Efficiency, quiet, stable performance.The APW7 can work stably in environments with a 50 temperature. If temperatures 50, the PSU should be underclocked. Considering the high temperature in mining operations, all internal components are with a standard of 105, so the APW7 has a much lifespan than a universal use PSU under similar high temperatures.Perfect function for protecting Miners, when circut is malfunction or power supply has higher inside temperature, it will shut off automatically to protect.including Over Voltage Protection, Under Voltage Protection, Over Current Protection, Over Power Protection, and Short Circuit Protection.One APW7 can power up one S9i, one L3++, one D3, one V9, one X3, one E3 or one Z9 mini. This APW7 has 5 pairs of 6 pin PCI-E connectors (. 10 connectors) ,Support back wiring, easy for to install machine, effective wear resistance.As with other mining equipment, the cooling fan and power cord interface are located at the front of the power supply, allowing for dissipation throughout the mine.APW7 can the stability of the cryptocurrency mining operation and can match the common load within 12V 1800W, making it Perfect for situations requiring such as mining.Features:: 12.0VRated Current (Input 220V): 150ARated Power (input 220V): 1800WRated Current (Input 110V): 83.3ARated Power (input 110V): 1000WStart-Up Time: Less than 2 secondsPower of retention time: more than 10msVoltage Range:100-264V ACFrequency Range: 47-63 hzPower factor: 0.99 (full load)Leakage Current: Less than 1.5mANote: confirm this item is the right model you need placing order.colour: silverMaterial: metalPackage Contents:1 supply with cablesOnly the above package content, other products are not included.Note: Light and different displays may cause the color of the item in the picture a little different from the real thing.
