Seller has 6 pairs left. Supermicro's marketing claims these are 1kW supplies but at 120V they are "only" rated to 800W. I bought a set to go in my SC836 with dual E5-2670s to replace a pair of PWS-801-1Rs, brought power consumption from ~350W to ~300W at idle and from ~500W to ~450W at load in my pretty unscientific testing. They seem quieter but it's hard to tell with the noise the rest of the gear in the rack makes.
