[QUOTE="Local Host, post: 934206"] No wonder you had issues with your PC turning off at 550W, clearly you had a white brand PSU, which is asking for issues. I still have a 650W PSU from Seasonic, which is still going strong and I'm currently using a RX 6800 with a R5 3600 at 4.5GHz. Any proper branded PSU like Seasonic has more than enough headroom for voltage spikes, contrary to white branded PSUs which can't even handle half the load they advertise. Thankfully power requirements hasn't changed much over the years, with each generation of hardware it either increases 5W or decreases 5W, in average always around same values. PSU is pretty much the component we rarely change over the years in gaming builds, there's a reason they come with 10y warranties. Bigger differences are in the different market branches (low, mid and high markets), so yes I wouldn't use a 550W PSU on a RTX 3080 build. [/QUOTE]
