Power supply or power supply unit 750w ASUS Prime Bronze For your build With an 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 a 5070, and it's 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.
