    My UPS is flaking out, and it's a really old one I got from work that was a 'server' class UPS.

    I don't want to drop $999 on the thing, as that's what an equivalent of what I was using go for. However I want my battery to last more than oh, 30s so I hope to size it right.

    Any experience from anyone running a UPS on one of these things? The UPS sites aren't much help and if the tech specs are to believed if it draws 12A at 120W that's a 1440W requirement for the power supply, and that seems a tiny bit high to me, but I might be wrong.

    I'm running the 2.66GHz dual core, the ATI1900XL, and 4 500GB drives in it.

    I thought the PSU in the Mac Pro was 1000 watts.

    I have an early 2008 mac pro and just picked up one of the APCs from Costco last year with the LED displays for about $150. I don't remember the exact model, but it looked like one of these:

    On idle I think my machine draws around 150 watts and with the monitor it is around 250 watts. I can run my machine and monitor for about 30 minutes with the UPS that I have. I am very happy with it.

    During the first months that the Mac Pro 1,1 was released I read many 3rd party references saying that the PSU was 1100 Watts. Now we have 1000W, 980W, and 1100W... :confused: Is there an official url with this spec listed? And also the efficiency maybe? :)

    As for actual draw my 2006 with all 8 RAM slots populated, 5 HDDs, two upgraded X5355 (120W) CPUs, and a 7300GT idles at about 200W, peaks at 350 to 400 Watts under very heavy usage and when I first turn it on sucks a 1 second jolt of 1200 to 1400 Watts - or used to when new anyway - the new SMC might have changed that I dunno.

    There was a picture posted of the decal on the PSU around here somewhere and it is in fact rated for 980W DC output.

    Kewlness! That's probably good enough. ;)


    Anyone know what the efficiency is?

    I have a 2.66 MP 1,1. Bought in March of 07. Mine is a 1000 watt supply.
