Yes you can. both 390 and 3010 motherboard work with standard 24/4 pin psu.
So I'm currently case swapping my Dell optiplex 390 sff and Dell 3010 I'm wondering if I can just use a normal full sized psu with the motherboard because the cables on the orginal psu are too short I currently have a 1200 watt thermaltake tough power and an evga 700 watt psu I got both for free from a family member and I want to use them on the case swap 
Psu upgrade
