I currently have an Asus TUF B450-Plus which only had 2 full size PCI-e slots, the rest (3) are just PCI-e 1x slots, are there any B450 boards that have more than that or do I have to step up to the next level to get what I'm after?
 
I don't think so - even if the slots are mechanically x16 slots only the first is electrical x16 gen 3, with the second being x4 gen 2

What devices is this for?


You probably want to be looking at x470 or X570 if you want more (but still not enough) lanes

Threadripper can meet your needs no problem - but it's not AM4 obviously

I run an unraid server off an AM4 platform and need more slots for expansion.

Gigabyte B450 AORUS PRO or ROG Strix B450-F Gaming (Note OcUK description appears to be wrong)

My basket at overclockers uk:
Total: £258.04 (includes shipping: £11.10)

Seems like the Asus ROG should fit the bill.
 
I've got that Asus board in my server for the exact same reason, I needed slots for a couple of RAID cards, network cards etc

Although you can always get 1x to 16x adapters.

Where would I mount the card though as the board is ATX and my power supply sits at the bottom (Define R5).

You can use x470 or X570 (or new B550 when released) with x8 HBA cards

I use a Silverstone ECS04 for 8 extra sata ports on my server with x470 motherboard. Potentially you could fit 2 of a card like that on x470 and then use some thing like a Zotac GT 710 which is available in PCIe x1 to drive a screen if you don't want to run headless
 
The AsrockRack x470d4u motherboard could be a good shout for an unraid build if you have deep pockets as well (also available in a version with 10GB ethernet)

B550 won't support the 2nd generation CPU's will it?
