Those are the molex to sata power adapters that are a fire hazard. I haven’t ever heard of this type causing issues and have been using them for years and years without issue.
Comment on Options to Expand Sata HDD Drives on a Lenovo Computer

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.
They aren’t wrong. Those SATA power splitters can be problematic due to subpar wiring and have been known to burn/melt.

Yes, exactly. The shop was probably thinking of the cheap Molex ones.

There’s also the possibility they’re referring to the current draw through the mobo connector itself frying things. A couple of HDDs at 12V, 10W will be pulling almost 2A which can be a lot for some circuit board traces, but there’s no great way know what the board can handle without documentation from the manufacturer or someone with relevantt engineering experience well above what a typical computer repair shop would have.
If I were OP I would just roll the dice and try it out. Its not as if old Dell office PCs are high dollar items.

Also a good point. Speaking of, that generation Optiplex SFF had a 300W PSU as an option in the XE3 model (meant for point-of-sale use) vs the stock 180W PSU. It’s plug-and-play, too. One of my Proxmox nodes runs a 7050 SFF with that PSU. It’s rock solid.

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 plug that fits just fine in the SATA plug on your ATX PSU, it may fry your drives when you plug it in. Don’t ask me how I know.
