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! |

At least it's modular  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

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

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. |

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. |

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. |
