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.

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

http://www.scan.co.uk/products/1500w-evga-supernova-120-pg-1500-xr-90-eff-80-plus-gold-sli-crossfire-eps-12v-fan-atx

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

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.


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.

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:

Single OR multiple 12V Rails: No longer will you have to toil over the decision of choosing a single or multiple rail PSU; the NEX1500 Classified lets you switch modes as you please.

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.

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

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.

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

What the..... Shocked Shocked Shocked
I've never heard of that!! Google Translate calls it the Asus ROG Xpander. Only works with their Asus Rampage III Extreme motherboard. Still, that's pretty crazy tho.

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
