If you are buying a used B450 AM4 ATX
Anything up to about $73.00 is a normal market price from a seller who tested the part and will take it back. Around $63.00 is a good buy. Below that, work out why: untested, no returns, cosmetic damage, or missing accessories are all legitimate reasons for a discount — and all reasons the price should be lower. A price far under the range above, from a seller who won’t answer questions, is the oldest bait there is.
If you are selling one
Listing privately around $63.00 is realistic if you are willing to photograph it, answer questions, ship it, and absorb the occasional return. Selling it outright — to a shop, or as part of a whole machine — lands nearer $49.00, because the buyer is taking on the testing, the warranty and the time. Neither number is wrong; they price different amounts of work.
