Dell Precision Workstation 490 Upgrade


Dec 5, 2017
I have a Dell Precision Workstation 490 whose psu is showing signs of impending failure. It has a single Dual Core Xeon 5050 cpu. Although it's ancient, it runs beautifully for my application. The problem is that the motherboard has a 20 pin and a 24 pin power connector, both of which are supplied from a single 750W psu. I haven't been able to find a psu with two ATX cables. Does anybody still make such an animal?
My other option is to replace both the psu and power supply. Does anybody know if the 490 case has a standard mounting profile so that most any motherboard will fit?
