That will do it!

Some people spaz out on awg and current but ignore them. That adapter is just fine, and safe to use long term.

Yup. The red/black/yellow is power, the red one next to it is SATA. They both need to connect to the HDD. And it should also be screwed in so it doesn't bounce around.

Edit:

SATA:

Yes there are SATA to molex power adapter.

"Molex to SATA, lost your data", because of high popularity of such adapter during the IDE to SATA transition, and low quality of many of those adapters. Getting one from a major brand like Startech that specialize in adapters with tons of positive reviews should be safe.

Would this work?

Sata-Power to Molex adapter.

Here’s an example

You're using these right? Toss them in the trash.

You can get a SATA to Molex adapter.

I could have sworn my Hue+ came with one already though...

I think we are getting into dangerous territory with the various cable voltages/amperages. The 6-pin/8-pin connectors are typically used to deliver additional power to graphics cards.

If you don't have any other molex connectors coming from your power supply, you could try a molex Y splitter with one of your existing molex connectors, and then plug a molex to SATA adapter into the PCI-E card.

Also, if you have another PCI-E slot, you could try that.

SATA to Molex LP4 Power Cable Adapter

look for something like that if you need it right away... (local web store)

Awesome, thank you! That's what I needed, more ideas on how to implement this. Either molex or usb or direct pins, one of them is bound to work.

And I do agree, All-in-one PC's are a bitch to repair ... thankfully in the 3+ years of owning this one, this is the first time I've needed to open it up. :)

EDIT: I've just ordered a (slightly complex) solution from Amazon. This all-in-one only has one SATA power connector coming out of the PSU that goes to the HDD, so I'm going to convert that into Molex, then use a Molex adapter that has a three-pin sprout,, connect the new fan to that, and then reconvert the power connector back into SATA, to plug it back into the HDD.

I feel like as long as all of the connections are tight and I keep it all tied down, it should work just fine. It's a bit more complex than it would have been if there was a three-pin connector on the motherboard, but no such luck. What do you think?

Thanks again for your advice.

It certainly possible to use an adapter like this one. However I generally advise against using them as most are extremely poor quality and are known to literally burst into flames. If you have the availability to add the modular molex cable back to your PSU always do that instead.

If your PSU only has SATA power connectors, then you may need a SATA power to molex converter like this one.

One of these?

SATA Power -> Molex.

By far the cheapest would be to find one of those two PSU molex cables though.

Sorry I misunderstood. I thought you needed power to the GPU. You can still convert your SATA plugs, just get SATA to Molex adapters.

I recently bought a Samsung 850 evo and still need to buy a power cable. I made the mistake of buying a male-Sata to power cable when I needed a female-Sata to power cable. I don't want to buy another cable and have it end up being the wrong one. Would this work with a Corsair 750M? Thanks!

You can use a sata to Molex adapter.

If you have a modular PSU check the box it might have the adapter.
Also some PSU will sneak a molex plug on a line that ends with a sata plug.

what do you mean your PSU didn't come with a molex cable? what model PSU? If it doesn't have a Molex cable, you would need a SATA power to Molex adapter. If you aren't powering it, that's why its not working.

Like I said, finding out what these things are called is the hardest part. Apperantly what you are looking for is Molex LP4 power connector and a 12 pin SATA connector.
https://www.amazon.com/12in-Molex-Power-Cable-Adapter/dp/B00GK8SYCW
Search for those connector kits and you should be good.
All that being said, you might just be best getting a molex extension cable :

That strip looks like it has a pass through to connect multiple molex devices. Male and female. Your power supply should have a female molex. If it doesn't, there are converter cables.

This plus this.

Building in the Node 304 case. Front fans running off a 2-way splitter from a mobo header (other mobo header in use by CPU cooler). Rear fan powered via molex cable from PSU.

Plan to fill this thing with drives eventually (6 HDD, 2 SSD), which requires 8x SATA connections over 2 cables from the PSU. This will preclude running the rear fan on molex directly from the PSU.

I had thought to use a SATA power splitter (e.g.) and a SATA-molex adapter (e.g.) to power the rear fan via a SATA connector (perhaps one that is used by an SSD).

I've read horror stories of converters going bad and melting (although those seem to tend towards molex-SATA converters and not the opposite). In that light I wonder if I should instead run the rear fan via 3-way splitter from the mobo header and avoid converters altogether. Any suggestions?
