If this is true, SLI is only supported on X370 chipset motherboards. According to this rumor, B350 will do CFX but not SLI.
https://videocardz.com/66369/psa-amd-b350-motherboards-do-not-support-sliAccording to ComputerBase, the AMD B350 chipset does support multi-GPU, but only through CrossFire. There is no SLI support. This information is still under NDA despite new motherboards and Ryzen CPUs being available for preorders. I know B350 is the budget-oriented chipset, so multi-GPU is may not be as popular as it will be on X370, but I think it's worth to know this beforehand.
wait, the CPU has a built-in SATA controller?

What's that there? Yeah crossfire support.

Looks like this mATX B350 does too, though at drastically reduced speeds due to the 2.0 x4. A riser-adapter off the m.2 slot would be faster.PCI Express 3.0 x16
1 x PCI Express x16 slot, running at x16 (PCIEX16)
* For optimum performance, if only one PCI Express graphics card is to be installed, be sure to install it in the PCIEX16 slot.
* Actual support may vary by CPU.
(The PCIEX16 slot conforms to PCI Express 3.0 standard.)
PCI Express 2.0 x16
1 x PCI Express x16 slot, running at x4 (PCIEX4)
* Actual support may vary by CPU.
PCI Express x1
1 x PCI Express x1 slot
(The PCIEX4 and PCI Express x1 slots conform to PCI Express 2.0 standard.)

Crossfire runs on just about anything with more than 1 PCIe x16 slot physically capable(even x1s with melted out backs) of slotting a compatible card.
What are the 6 and 8 pin power connection on a psu for?Originally Posted by kevinf

1x and 4x (electrical) slots, will not provide the appropriate power to the card. In this ASUS board, thankfully they have an 16x electrical, but 4x signal.
did you forget the issues with regards to polaris's excessive peg power draw?
Can we use that to determine anything? No because it is not a norm. My FuryX does not have that behaviour.Originally Posted by epic1337

no, i'm implying the implications of exceeding the PCIe power limit, you can look up the whole fiasco blowing out of proportions.
PCIE Slot (up to 75W)
I understand all that. Just saying when did the Rx480 become the standard for PCIE power usage?Originally Posted by kevinf
PCIE Slot (up to 75W)
75 W (6-pin) or 150 W (8-pin) power for up to 300 W total (2Ă—75 W + 1Ă—150 W)
So if you have an electrical 1x slot, there is no way it will provide 75W, and if you have a RX 480 with a single 6pin, it will either melt the slot, or the 6pin while trying to draw 150W+ (combined slot + 6pin).
If you have a small passive card (eg: AMD 6450), I have successfully ran it off a 1x slot with a 4pin (floppy) power connector, on a riser board.
HOWEVER, I also melted that 4p connector when I ran an OpenGL stress test

you're misunderstanding the thing about RX480.
Crossfire isn't too picky. I believe it can work with a second GPU in any slot, but I cannot confirm that. I know for a fact that a number of motherboards offering only one x16 slot and a single x4 slot will support it, stuff like your B150 and A68 chipsets. I don't know about x1 or x2 slots.
...can be blamed entirely on Nvidia. Nvidia requires an x8 link minimum per GPU. PLX switches are of course allowed, which is the only way 3-way and 4-way SLI (barring dual GPUs of course, but then again I think those have on-board PLX switches) on LGA-115X even functions. There is absolutely no reason for this either. PCIe 3.0 x4 does not support SLI, yet has just under twice the throughput of PCIe 1.1 x8, which does support it. It's completely arbitrary.
