Will a 5.5cm thick Sapphire Nitro RX 580 fit a Micro ATX motherboard?

I just ordered one of these and now I'm concerned it won't fit.

My motherboard is this:

The card I ordered is this:

https://www.overclockers.co.uk/sapp...ddr5-pci-express-graphics-card-gx-37n-sp.html

Can anyone reassure me here? I suppose I can always return but if it doesn't fit I'd prefer to cancel and get something smaller.

I do not see why it won't fit. The sizes are standard, except if Asrock went the extra mile and raised the size of the heatsink found on the chipset. But it if has done so, no GPU would fit.

The case is the issue if something doesn't fit, not the motherboard.
Though if you try to use the bottom PCIe and you got a 3 slot card, then you cannot use it.
 
Hard to say for sure, as Asrock dont provide GPU compatibility lists as far as I can see. However, this https://www.userbenchmark.com/System/Asrock-B450M-Pro4/93462 suggests RX580s are compatible. You could do a search on there for that specific GPU and see if the B450M Pro4 comes up, but its still not 100% confirmation. I would hazard a guess that your case will be a more limiting factor, as the card should happily sit above any motherboard components.
