Hi, I have this chassis http://www.supermicro.nl/products/chassis/4U/846/SC846XE26-R1K28.cfm?parts=SHOW It is equipped with two redundant PSUs and a power distibutor with four slots. Two occupied by the PSUs and two others free for any battery backup power. In the latter it is possible to install additional PSUs. The power distrubutor has 6*8pin EPS receptacles, 13*4pin ATA receptacles and 8*8pin EPS headers. At maximum current the PDB should transfer a theoretical power of over 4400W. I have some questions to ask you: 1. Given that the load is distributed on two PSUs, what happens if the total load exceeds that allowed by a single PSU? 2. Is it possible to configure a redundant N+1 PSU system?
