Metal case dimensions (Length x Width x Height) in centimeters: 15.0 x 8.2 x 4.1 The 120V black plastic power receptacle extends 0.4 cm beyond the power supply's metal case. Not shown in Newegg photos is a small metal mounting bracket that attaches to the power supply's metal case with two screws. Two holes for the screws are visible in the metal case on each side of the black 24-pin female power connector. When the bracket is attached, an additional 1 cm is added to the *LENGTH* of the power supply and it accommodates two more screws for mounting the power supply.

does this ship with cables as well?

Yes. 24Pin Motherboard, 4+4 CPU, 3x 15pin sata, 1x 4pin molex, 1x floppy drive,

Would this be a good power supply to replace the dps-220ub a power supply that comes with a lot of small form factor prebuilt computers from the early 2010s?

I think yes. You only need to check the rear dimension of your psu is 80mm * 40mm and mounting screw holes
