Customers have mixed experiences with the cable's ease of use. Some find it plug and play and easy to use, with the cable plugging right in. However, others encounter issues with loose pins and wires, connectors that no longer line up, and difficulty plugging in the white connector.
Pins are loose, hard to align. Only because it's transparent I could manage to align all pins, after that it did it's job.Read more
Exactly as ordered, Slight issues with the pins when connecting the molex but that seems to be more an issue with the Molex connectors in general...Read more

5 customers mention compatibility, 2 positive, 3 negative
Customers have mixed experiences with the cable's compatibility. Some find it exactly as found in all computers, while others note it needs a third molex input or requires the additional 8-Pin PCIe cable. Several mention the cable is so specific that some PSUs don't have the proper connectors.

    Works as intended. I purchased this for a "Retro" build I made as a hobby and used this Molex Power Adapter to feed enough power to my GeForce GTX 2GB 770 Superclocked and it works like a charm! Note to anyone considering purchasing this. Please, check your power supply (PSU) and ensure that by using this cable you are not drawing too much power. If your PSU can't handle the voltage you do risk starting a fire.
