Short answer: The Seasonic Core GX is my 650W pick: compact at 140mm deep and well built, though the fan always spins. There are 17 650W units on my list: 5 in Tier A, 8 in Tier B, 4 in Tier C.

How to choose between them
- Check your card first. 650W suits mid-range cards. Anything from an RTX 5070 Ti up needs more.
- Leave room to upgrade. If you might fit a bigger card in a year or two, 750W often costs little more.
- Size. Compact units like the Core GX suit small mid-tower cases.
