Summary: The wife wanted me to put the computer in the computer tower stall that was part of our computer desk. These adapters work great for powering the 120mm fans I installed into the desk. However, I did have one of the wires pop out of the molex connector on the adapter, resulting in one of my desk fans not running. Took a minute to find the problem, jammed it back into the connector and we're back in business.
Summary: Got this to be able to add more fans to my Cooler master case. The connector is decent quality and works fine to serve the purpose of being able to add up to 4 more fans. Although I do think the price of 5 bucks is a bit much for this piece.
