Considering this thread is about cooling, what are you doing? Hooking up a 12V high current car fan to the PSU?
It's all pretty well explained in last few posts. 8 fans, 3 of them NF-A14 IPPC to be powered and controlled with 2 Gelid 4-to-one PMW splitters with PSU power. 5 fans on 1 splitter and 3 NF-A14 on other.
So while adversary is being overly worried about the 3-5 times more power fans draw at startup or if impeller is stopped, trying to figure out and optimize the problem is a good thing.

If PERIF cames as not enough, what exactly you propose? Can I take +12V from VGA connector on PSU?
Seems PERIF is a ghost.

I gave you links showing most if not all power cable ends used for motherboard, GPU etc as well as pinout and amp ratings.

So far as I found, these PERIF connector on PSU should have more amperage than SATA connector. You can also take a look into link you provided.

As PERIF to Molex cable is pretty short, and spin up time of fans is just moment, there should be no problem using 18 AWG wire I think. Even if fans take 10A at this moment. After that, fans work at 2.15A (if pushed to max) and it is safe.

I just need to dig more around to be 100% sure about that PERIF connector if that will be choice of use.

Because I ordered 2 sets of Gelid 4 way splitter. Idea is to run 3X Noctua Industrial 140mm 3000rpm, which are rated by Noctua at 0.55A, on one Gelid splitter. On other Gelid splitter, I can use 5X (5th fan with Y splitter) Noctua Industrial 120mm 2000rpm, which are rated by Noctua at 0.10A.

Now, all these 8 fans draw 2.15A total as rated. Now multiply it with spinup higher demand and we have....?

If I could somehow know is my PERIF connector and cable are capable, than problem would be solved. Just connect Molex from Gelid splitter connector to each Molex connector which PERIF provides.

So, option can be PERIF if I can get 100% info how much amperage it provides (it is allegedly for older HDD-s and such, maybe they really provide more).

Other option - if I get you right? To use VGA to Molex adapter, and use VGA connector from PSU.

God only knows, because FERIF isn't a specific connector, just something PSU manufacturers us and don't tell us any specs.
No, I said "New SATA gas 3 connecters rated 4.5amp 12v". I fat-fingered "has" with "gas".
I've sense found that is is 1.5amp on each, so a total of 4.5amp.

Why don't you just use 2-pin, 2+2-pin, 4-pin, 6-pin, 4+4-pin, 6+2-pin and 8-pin ATX +12v/EPX +12, PCI Express Molex power plugs on PSU for GPU and/or motheroboard power? They have the highest 12v power ratings. Link below has all the specs for you:

I have the 1000P2 series plus a couple others 850P2 and 1200P2.

I have EVGA 550W B3 not used, EVGA 1000W G3 which is now in use but with EVGA 1200W P2 cables. Because my P2 died three years ago.

When I compare cables, for example, PERIF and SATA, all are same from B3 to P2. Only VGA cables from P2 are thicker (did not pay attention on CPU and mobo cables, they remained from P2 anyway).
