Question PSU suggestions ?

[Alectrona]

I need a psu to power my system, here are the specs:

cpu: i7 2600
gpu: rx 580 (msi oc edition)
ram: 8gb
OS: Windows 10 pro
drives: 500gb hdd, 500gb ssd
mobo: optiplex 790 mt

I need a psu to power this pc. I do not plan on upgrading parts in future for obvious reasons. Legit am just throwing a bunch of spare parts I have for a pc my little brother can game on. I was thinking a $50 msi mag a550 but if anybody has a better suggestion preferably cheaper please let me know, I am assuming I could use a psu with a lower wattage.

You should be good to go, actually, with the MSI PSU you've listed above but what sort of spare parts are you looking to throw in there? If I were you, I'd pick up a unit with slightly more wattage like 650W, something that was 80+ Gold rated(so you can migrate it to another build in the future) and call it a day, something like this;

You can't go lower, well, you could if your card wasn't power hungry and a hot head.
