Tai_Pan almost word for word same experience I have with trying to order..... but may be a good thing because I saw that someone mentioned that there could be some power problems with them as they can top out at 800 watt and only have 3 pci-e connectors to power 3 boards.. that's a lot of juice on those lines... not sure how safe that would be?
As for the power issues, I think Baikal would have figured it out before delivering. 2 in 1 pci-e cables to share the load, perhaps?
Even with the 2 in 1, it still ends up to 1 PCIe connection that is receiving 266+ watts to a board. Even if you have a 3 in 1 or 4 in 1 PCIe connection, it's still just 1 PCIe jack that is taking all the power. That is the concern that I see. Lets say for example you use a 3 in 1 PCie cable so there will be no fault to the wires at all since there will be minimal resistance. Would that PCIe jack fail instead? I know wires/gauges are rated for a certain amount of amps/watts, just not sure what those PCIe jacks are rated for.
