Upgrading and recommendations

[ToxicBurrito1418]

I want to upgrade my pc. I bought a Cyberpower pc last year with a rx580 4gb and an i5 7400 with 8gb of ram. I do not know the psu. What should I upgrade first (I want to get better frames in games such as cod or pubg)?

Depends what you are using. Use MSI afterburner to monitor your system. When you play PUBG what CPU% GPU% and how much RAM are you using?

Knowing the make/model/wattage of the psu is as simple as opening the case up and finding the label on the unit...
