Question PSU Molex to multi-sata connection

[itz_nsn]

I am building a desktop with a bunch of old had disks, but am running out of PSU to sata cable connections.
My PSU has 2 additional PSU to Molex connectors lying around. Can I use these to connect power to 4 additional hard drives ?

See pic link: PSU and Molex

PSU Model: Cooler master 800W Silent Pro
Available: 2 Molex cables
Want: 4 more sata power connections
Connecting to: Western Digital Green 1 TB 7200 rpm 3.5 internal hard drive
Planning to buy: https://www.amazon.ca/StarTech-com-PYO2LP4SATA-Power-Cable-Adapter/dp/B0002GRUV4/

Will this work to power up the drives ?

Thanks for your help.
