Here's one for the rig builders - really wish I'd been able to get one a year ago  :D

Does 1650W on 230VAC - enough to run a 7x7970 rig with a bit of undervolting  ;)

I can't see anyone buying this. First, who's building new GPU farms from scratch anymore? Second, if you are, 2 1KW PSUs would probably be cheaper.

That and the sheer number of 12v rails to contend with is troublesome.

8 rails at only 20A each? You can barely run one GPU on each rail!

That's what I'm saying.  ;D

For the price it's not worth it. Get 2 single rail 1250s or better yet get 2 of these: http://www.newegg.com/Product/Product.aspx?Item=N82E16817171063 (http://www.newegg.com/Product/Product.aspx?Item=N82E16817171063) for just $50 more!

At least it's modular :P If you just thought "really? REALLY?" I have a 900W PSU, silver certified, nice brand name, 4 6-pin, and it's not modular.  It has black mesh wrapping so it looks like one of the sentinels from the matrix lol.

The PSU would not be able to handle all 16 connectors in use, Maybe for smaller single GPU cards but then most power supplies right now can handle 5-6. I only mention this cause I had 3 6990 in a water cooled system and I blew a capacitors in both a 1500 and 1600w power supply that have thier own dedicated 20a plug I evently went back to air cool and had to splitt the PSU's and built 2 seperate systems. So unfortunantly as the ole saying goes in some situations bigger is not better.

If you had a MB that could run 8 5830s, this might work. A 20A rail dedicated for each 5830 might work.

20amp rail is plenty for most everything but a 5970/6990/7970 in fact I have a power supply with 18amp rails that runs 5870's fine. You could run a 5970 or 7970 undervolted probably even

5850/5830 are about 155w at stock speeds

Hell I guess this mother board could be used.
sorry its in a different language

Whoa!!  Why have I not heard anything about that expander before??  :o :o  That is too cool.

What the..... :o :o :o

I've never heard of that!! Google Translate calls it the Asus ROG Xpander (http://www.asus.com/Motherboards/Accessories/ROG_Xpander/). Only works with their Asus Rampage III Extreme motherboard. Still, that's pretty crazy tho.

that board would have been killer a year and a half ago, lay it out on a table slap 8 cards in there and be ready to go. lol my aw dropped when I saw it doing some research for better settings and overclocking using voltage and some how stumbled upon it on fortunantly you could only do 4 of thim with this but keep them nicely seperated.

You should be able to run that rog expander on any board. It's a simple nf200 chip connected via pice.

16 pci-e connectors, but 8? rails. No thanks. You'll probably be lucky to pull 800 watts from that thing without forcing a shutdown because of over current protection. Single rail forever.

While 8 rails at 20A each =/= 160A, it does say it's rated for 124A between all the rail, so that's ~1500W, not 800.

It also says on another site that you can switch it to single-rail mode (which seems odd) and that it does 1650W on a single rail if given 230VAC.

Linky........?

Holy crap I missed that. I wonder if they just link all the rails somehow? Even in the link in the OP:

At £344.58 one might be better off buying several smaller power supplies, name brand 500W and 550W power supplies seem to cost about £40 or £50 or so so one can have 7 for the same outlay in cash.

My first rig used an expensive 1200W PSU... which lasted about 18 months.

Subsequently, I have used multiples of 500W and 550W power supplies without any failures. I have a spare 550W Antec standing by for when one does go down, and have still spent less cash than if I had bought big PSUs.

GPU's, thats soo 2011

Takes up lots of space, though.

Nice idea with the redundancy !

The space isn't that much of an issue - my rigs are in the attic where there is plenty of room.

Picture a motherboard with 4 5780s, some attached using PCIe x1-x16 connectors, powered by 2 550W power supplies, on a shelf. Add a water loop for cooling. A bit... untidy.
Between 3 such rigs I get more hot water than I need. If I thought GPU mining was going to be worth doing into the far future, I might consider growing tomatoes in a heated glasshouse.

This is apparently the PSU that's inside the BFL Minirig SC.

You wanna post a link for that info?

Not really. It's somewhere on BFL's Minirig forum.
