I was going to upgrade my card only then decided to just build a new rig. According to every tdp calculator it should be enough. In my experience, it IS enough. However, I keep reading comments everywhere saying anything lower than 600w is trouble. Even the website's review recommends 600. 4790k (plan to OC to 4.4-4.5ghz @ 1.3v) nzxt x41 980 ti g1 gaming (OC) 1x SSD (ocz vertex 460) 2x 3.5 inch seagate NAS drives. 2x 1866mhz ram sticks @ 1.35v I was going to throw my current 550w psu in the new rig and put a corsair CX in the old one. Should I be worried? Should I just get a new PSU?
