Ok, so I'm looking at moving most of my servers/home lab equipment to a new rackmount style custom built cabinet because I'm looking to add some new hardware into the mix. I already have one ATX pc in there, and I am looking at adding another for firewall plus maybe a 3rd if I get a decent price on it.
I have a 1.2Kw Dell PSU doing nothing and was wondering if it would be feasible to run the 3 boards from the one PSU?? I've done some reading up on the subject and have seen its achievable but a bit confused as to what issues I may have. The PCs in question are 1x i7 920 Dell/Alienware Mobo and nVidia 210 GPU (no dedicated power from PSU) this is my main rig and proxmox host, Q6600 Gigabyte GA-EP45 mobo undecided GPU but again will be low power fanless model this will be firewall, and then a 2nd gen i5 mATX with onboard GPU for testing/2nd proxmox host. Between them they will have 10x 3.5" HDD, 2x SSD, a DVD burner, 2x USB TV tuner adapters, 2x Quad Port NICs. Cooler Masters PSU calculator has given me 900w so I think I have room, but just need some other peoples advice on the subject.
I've modded a couple of PSUs to be on all the time by shorting the green wire to ground and adding a load to 5v in the shape of a 10w resistor, which is what I am thinking of doing to this scenario.
What I am unsure of is the behaviour of each motherboard in this situation. I still want to be able to power down each motherboard individually to work on them so will this still work??
Cheers
Iain
