I dont really have any issue with it, it gets the job done.
However, I'm planning to switch to teh ASUS TUF Gamign RTX 4070 Ti. ASUS recommends a 750W PSU for it, is 50W really a big deal and I need to upgrade my PSU or would I be fine with it?
Even if you current PSU can run the 4070 Ti, you'll be pushing it to its limit, and your next upgrade will definitely require a new PSU. I say if you have the budget you get one of the latest ATX 3 PSUs...
