Power supply or power provider 750w ASUS Prime Bronze For your build With i5-14400F + RTX 5060 Ti, 750W capacity is more than enough, and its 12V rail has the full 750W, which is excellent. It works for this build and for the 5070 and is great. I bought it from Amazon for around 450 and haven't opened it. I canceled my PC build and am selling it new in its bags. We won't disagree with a serious buyer, God willing.
