AT Molex to SATA Power supply cable

Generally, true AT Molex to SATA Power supply cables DONT exist. This is because the AT connector does not supply 3V, SATA does. Luckily most SATA devices don’t use 3V. So you can get by with omitting this pin, which is what most commercial adapters do. The picture below shows a Molex connector should be wired to a SATA connector to provide 5 and 12v supplies. On the SATA side I relied on the cable colouring being standard. Though it would be more sensible to get out a multimeter and test them against the pinout.
