So, I'm in the process of building a new rig. Long story short, I was ordering a PSU on newegg the Seasonic Focus plus 850 watt. Well at least I thought that's what I bought. I saw later on that I actually bought the Seasonic Focus plus Platinum 650 Watt power supply. I plan on overclocking my R7 2700 and RTX 2080 ti. Did I fuck up and get a power supply that's too weak? Can I just return to newegg and buy a stronger power supply? I have premier so return shipping and restocking fees are a non-issue?
