u/404nova

i am in need for one of those . my psu molex are powering my gpu and i only got sata cables left , i want a converter to turn them into molex so i can power up my fans . i will power them for molex but they have 3v argb connectors but my motherboard have 12v rgb ones can anyone suggest how can i get rgb working on my fans and i can trade a new packed sata cable for connectors and shipping too.

no need to read this but this for context -
i was using my pc without a cabinet and gpu motherboard solely in a cardboard box recently i saw a listing on olx of ant esports ice4000 for 2000 i thought it was good deal and bought it product in itself was good my psu cpu connecter fall short by an inch somehow it worked there is some tension in the wire but it will be fine the power supply i was using was ant esports vs400l (ik it is cheap but when i bought 2 years back it was fine or my build ) i also bought a gpu from olx too recently which is 1650 which i got for around 5500 incl shipping it was also a fair deal considering it has 7 months of warranty remaining fortunately its old user was using a molex to 8 pin one so got with the gpu which is i am currently using now . so my all psu cables are in use except sata ones which i thinking to use for fans , and as i have mentioned up there my motherboard is not comaptible with my argb fans what i can do about that ?

thanks for reading.
