PowerSupply problems installing only disks in a new PC case


I need to add some disks for a server with no more physical space in it.

I will add 4 SCSI disks in a new and unused ATX-case. Since I will have no motherboard or anything else in the case to plug the on/off cables etc. into - how do I get the the power supply in the ATX-case to work?

Is it possible to 'fake' the powersupply into believing that a motherboard is installed and working - so that I will have power delivered to the disks or do I really need to install a 'dummy MB'?

As always: TIA!

change out the ATX power supply with an AT power supply.  All you need to do is add a 2 pole double throw rocker switch.
