Options to Expand Sata HDD Drives on a Lenovo Computer (lemmy.ca)

I bought a refurbished Lenovo M720s computer last summer to use as a homelab at my house. I loaded True Nas onto the internal SSD and swapped out the HDD drive that came with it for a 10tb drive. I also threw a 500gb drive in the M.2 slot to use for applications with True Nas.

All has been fine up to now. Recently though I aquired a 8tb HDD for cheap and figured I would throw it into the homelab for some extra storage. There was a extra Sata connector free on the motherboard anyway. I put in the drive and connect it, but then I realize that there is not another Sata power connector I can use for this drive. This computer makes you connect power to the drives from the motherboard and not the power supply.

So I am at a bit of a roadblock. I know I am pushing the capabilities of this little machine, but it seems silly that they give you 3 Sata ports but only 2 power ports for Sata drives. I guess they were probably intending for one of those ports to just be used for a DVD drive.

I went to a local computer store and they were not very helpful. I asked if I could use a splitter for the power port and they said I would fry my board.

Anyone know any solutions to this? I just need a way to power one more HDD. I will link the manual to the computer so it is easier to see what I am looking at.

Another thing they may have in mind is ATX PSUs. The pinouts on those for the same physical plug vary not only by maker and model but sometimes even by year. So if you get an aftermarket ATX-to-SATA cable that fits just fine in the SATA plug on your ATX PSU, it may put 12v on the 5v and fry your drives or mobo when you plug it in even if it's from the same brand.

Don't ask me why there is a voltmeter on my desk.
