My Power Supply broke down earlier, started to smell smoky. Not good. Need a new one quickly. The old one (and I mean old; from 2012) is a Dell 300W supply. I'm looking to upgrade a few components in the future. I'm thinking 400/450W will be good enough for now, but I'd like to know if all power supplied are the same size, will the screw holes in the case line up with the one I decide to pick? Do all power supplies offer the right cables for my pc? Are all supplies set up to suit most setups?
Cheers.
