Ok just started a thread of examples of PSU's maybe you, me or we would be better off saving and try to sell whole. I'm no expert on this so anyone that has input please join in and contribute to the information exchange. My example is a Achme AM630BS20S 200 Watt, ATX & SATA connectors. First I pulled from a working Shuttle computer. Another reason I'm not going to scrap it, this is small PSU weighing only 1 pound 11 ounces. Don't seam like any thing there! It is known as a switching PSU, honestly don't know what that means. Also have read they are known as "FLEX" PSU's again don't know why? Maybe because I notice it has more connectors than most I have seen. Connectors 20 pin ATX (1), p4(1), molex 4 pin (3), molex 3 pin (1) and SATA (2). Has a small fan and power receptacle on opposite side of wires and connectors. Dimensions 6" x 3 1/4" x 1 1/2" like I said small, smallest one I have seen. On EBay seven recently sold used ones for $10 to $40. I will hold this one back from the scrap pile and will try to get a better than scrap value out of it.
