(Looking for a case)
Apevia PSUs are listed under Tier 5, the lowest. Highly recommend you get a different PSU. See here
Any Redommendations for 650W?
Try this one. While it may be a bit more costly, it proves you shouldn't skimp/cheap out on PSUs. If they fail, it'll take your hardware with it. Plus, it's much more reliable, and it's 80+ Gold Certified.
What does that mean "it'll take your hardware with it"?
Sorry for being vague, but it means that anything connected to the psu will most likely fail once the psu gives way.
Get a different power supply. That brand has a bad history of failing...
