will this work with just 1 sata power?

[gsammi876]

I only have 1 Sata power cable and that’s in my HDd if I get this : https://www.amazon.co.uk/StarTech-Power-Splitter-Adapter-Cable/dp/B0086OGN9E

Can I power multiple hdds from just that 1 Sata power

Probably.
But what PSU do you have that has only one SATA power connector?
