As above really.

Have a Dell 1440w server PSU nearly ready to go, but need to know if I need to use the 'MOBO' PSU to power the risers?

Thanks
There are several different types of Bitcoin clients. The most secure are full nodes like Bitcoin Core, but full nodes are more resource-heavy, and they must do a lengthy initial syncing process. As a result, lightweight clients with somewhat less security are commonly used.

Also, how much power is drawn through the powered risers?

Powered risers molex draw max of 75 watt which is the same as if you use 16x PCI-e riser without molex.

Thank you.

Do the powered risers have to come from the same 12v rail as the motherboard?

This question is unanswerable - it depends on the PSU.

They should because of voltage difference between both psus. From experience I would say that best idea is to power risers from one psu, even though with some psus it works other way without problems.
