You don't have a GPU? You won't use more than like 200W (not saying you should get a 200W psu..) 500W is fine.
It says Geforce 550ti on the bottom as a custom part, because I'm gonna get one off my friend.
Oh that makes more sense! Sorry didn't even see it.
Still, you will be fine. I run an i7/780 off 500W with no issues, people have even done it with 780 TI. Definitely no worries.
It's okay! Thanks for answering!
