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.

Thanks, got 2 pairs.
These are about as efficient as the 500P's at 250W but more so on higher wattages (and less on lesser), but they should be nice for my two dual SP boxes :)

Really, have they become so cheap? Last time I checked I couldn't find any below $150. O/c that was like a year ago or so

If you search for "supermicro titanium" a few listings pop up around $70-ish whereas the price point for the platinum PWS-920P-SQ is around $55 at the moment.
