Question I have a Supermicro CSE-836TQ-R800B case that is a couple of years old and I would like to upgrade the power supplies in it to something that is quieter and more energy efficient. It currently has two PWS-801-1R (801-1R 800w PSUs) with the PDB-PT825-8824 power distribution board. Answer You may use PWS-920P-SQ (920W 1U Redundant PWS W/ Quiet Mode) as a quieter and more energy efficient power supply. Was this FAQ helpful?
