My SC846 has 18 drives in it now all 4-5TB spinners but I doubt the draw is that high but I haven't checked. I'm not sure how to check the consumption thou.I have these they are quiet, I hear the air sucking in the front over these.
BUT you are wrong sadly, 1280w does idle higher than 900 watts, and deff. more than 500 watts. The difference for you depends on your total draw at idle. The lower your idle draw the more inefficient this will be.
If you're using mostly SSD or not HDs then you really want the 500w drive or one lower, even something not platinum but quality 300w-400w will be more efficient.
I'd like to know as well. These are considerably cheaper than the 920W SQ's that are available right now and I'm pretty sure when I fire up my new SC846 I'll be ordering an SQ.Any idea if these are as quiet as the 920W?
Its over 90% efficient at 10% load, far better than typical older crap.With likely 300w or less at idle your sysstem would have 1000w in excess :X
I don't think you'll make the $ back anytime (years) soon. Even if you got them for $50 each that's a lot of power. With likely 300w or less at idle your sysstem would have 1000w in excess :X

...Expand the above.Sorry but this makes no sense:

If your server pulls 130W it wastes a big fat 13W. A 500W platinum at 130W would be around 95% and waste 6W or so, at 10 cents/KW/h it would be ~$6/year difference in efficiency.
Unless your server is massively under-powered (way under 100W) for the big supermicro rackmount case it is in, I would not give two flips about finding a lower wattage PSU and jump on a good deal if you need one.
you can cut the pcb to make fit on the PS slotMake sure these are compatible with your chassis before ordering them!
I got a few from another seller for about 75 each after shipping, only to find that they only fully plug into my SC847 36-bay 4U chassis, but not sc836 or sc846 or the 2U chassis. It all depends on the power distribution backplane the PSUs connect to - the 920p-1R and -SQ PSUs all have a narrower card edge - the 1.2K 1R gold PSUs also have the narrower card edge, but these 1.2K SQs and the 1.4K 1R golds all have a wider card edge which goes to roughly 1/4 inch from the edge of the PSU vs roughly 1/2 an inch from the edge for the lower wattage PSUs.
