Do the Molex Powered Risers need to come from same 12v rail as MOBO?

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

Each block is stacked on top of the previous one. Adding another block to the top makes all lower blocks more difficult to remove: there is more "weight" above each block. A transaction in a block 6 blocks deep (6 confirmations) will be very difficult to remove.

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.
