[SOLVED] Need some help, missing pins!

[Benjamin0403]

Hi guys!
I have an old pc and I won’t buy a new one before ddr5 and the new chipsets are out. I just bought a crucial mx500 250gb.
I have an old dirt cheap 400w power supply with 2 sata cables. My problem is that both cables are missing 3 pins next from the L shaped notch. I searched for answers and found that those are the 3.3V pins and on paper my ssd doesn’t even use them. Am I right? Can I use a 12 pin sata cable for my new and shiny ssd? Btw this is my first ssd ever and I’m not a tech guy, I just don’t want screw it up. I have some free molex cables but I don’t want to risk using a molex to sata adapter and then burning down the house.
Thank you for helping me out.

SSDs use same pins as HDDs, don't need 3.3v for them.
