Question Additional Sata for hdd in my PSU

[martinezkier.dacoville]

Good day, My current PSU only came with 1 cable for a 6 pin to 4 sata which I use for my HDDs (3x3.5" hdd and 1x2.5" hdd) I upgraded my laptop to an ssd now I have an extra 2.5" hdd which i would like to put in my PC but I don't have any sata left. Is it fine to use a molex to sata or i get a sata splitter for my 2x2.5" hdds?
My PSU is a 650w gold rated Huntkey MVP brand. My system is pretty low powered just an i3-9100f, gtx 1070 and 2x8gb rams.

Molex to sata would be fine for a simple hdd. They don't use much power at all
