If you want to purchase a cheap system and upgrade to SATA optical and hard drives, without getting a new power supply. This product works great with older power supplies that don't have more than 1 SATA connector. The SATA connectors on this product are also much easier to plug into than the typical SATA connector. Maybe it's just because of the power supply I had but they plug in easier for me.

Adds 4 SATA ports through an otherwise hard to use Mini PCIe port. The card runs an option ROM on boot and shows you all the drives connected and at what speed. All my drives were immediately detected in Windows 10 with no further driver install needed. The card has onboard LEDs to show detection and activity for each individual port. In the box was 4 SATA cables and two Mini PCIe hold down screws.
