I only see two pcie 8-pin connectors on that PSU. You will either have to get the XC3 or upgrade your PSU.

The specs on the Corsair Website says your PSU has 8 PCIe connectors. I looked at the picture on the back of the PSU and it looks like it has six 8-pin pcie slots and two 6-pin pci slots. So yes, you will be able to hook 3 separate pcie 8-pin cables to the RTX 380 FTW3.
It may be that you are thinking that the pcie cables that are 6+2 are split cables, they are not, they can be used as 6-pin or 8-pin. For 8-pin you need to put the top of the cable together to form an 8-pin connection.
Crap, I posted the wrong link. This is my PSU-
That still takes me to an 850w, 80 plus Gold Certification PSU. The PSU is listed as having 4 PCIe connectors (2 cables with 2 full PCIe connectors on it.). This gives you the headroom you need to connect a 3080. I'm using a 750w Seasonic PSU with the same basic connector setup as yours and know I can connect a 3080 to it. One of the cables will be using both 8-pin connectors and the 2nd cable will go to the 3rd. If you did purchase the 1000w PSU, you're definitely going to have plenty of headroom for future upgrades and overclocking until you hit the Threadripper territory.

My question is, is it safe to use one of those additional 6+2 pin connectors hanging off to the side?

I have the same kind of cables. I have no knowledge about the safety of using both on a single card. I think I saw some articles talk about the recommendation for using separate cables, but I didn't really read into their explanation since it seems common practice to include two connectors on 1 cable from many PSU manufacturers. If I were you, I'd be comfortable with that PSU due to the headroom and Gold certification and that it's from Corsair, which is a reputable brand. But your comfort level will vary of course. If it'll make you feel better to have separate cables, then by all means, proceed with the 1000w PSU. It'll definitely give you room to upgrade in the future without upgrading the PSU.

Like I said, yes, I think it would be fine. Safe? Without a doubt. Corsair wouldn't make that cable if Corsair didn't think that it could handle at least 300 watts. The three 8-pins are designed to meet the minimum specifications (which are pathetic). EVGA puts 3 8-pin connectors on the card so that 1) it looks like a powerful beast of a card which must be better for some reason, and 2) so that you can use the absolutely trashiest power supply which barely meets the ATX specifications, and it won't start on fire. Your Corsair power supply is not a piece of trash and can handle way more amperage (and thus power) than the minimum specification, and therefore it is safe; without a doubt. Like I said in the other thread, which I linked to above, watch this video: If you have the attention span, pay attention to what he says about amperage rating, cable gauge, and temperature. The minimum specifications are just the absolute bare minimum for the worst trashiest PSU which can still be sold. Respectable PSUs, like yours, use much better wires and connectors. Again, Corsair wouldn't sell the cable if it wasn't designed to handle the power.

Wait, is using a Split connector safe for this kind of card?
Using two connectors on the same PSU cable is safe but it's best to avoid if possible. If you have to use though it's perfectly fine. Also using the 6+2 is just as good as using an 8 pin cable.

Ok so I did some research on my psu and it's not very good other than being an 80plus gold. I'm gonna try to get a xc3 ultra and if I can't but can get a ftw3 I'll just buy a ftw 3 and a new psu.

hey, that video was really informative. im currently in line for the ftw3, and my psu is this exact model www.thermaltake.com/toughpower-750w-gold-modular.htmlit did come with pcie cables that have split ends on one side. so i can theoretically plug into 4 pcie 8 pin connectors. would you say this power supply is good enough to plug both my pcie cables into the card, and then use one of the split ends for the third pcie slot on the ftw3?

Use an individual cable each for the 1st and 2nd connectors, then use the daisy chained plug from the 1st connector to the 3rd connector. IIRC on the GPU-Z readouts I've seen, the 2nd plug pulls a bit more power, so that's the one to put on it's own cable. https://forums.evga.com/G...nd-board-m3085826.aspx Should be ok in general, but you'll be pushing the PSU pretty hard at max power limit and it might not OC as well as if you had a superb oversized PSU.

Back when Ethereum mining was a thing, I would use a single cable with a daisy chained 6+2 for each 1080 Ti. An EVGA G3 1000W would run 24/7 for weeks on end without issue powering 3 cards each in that configuration. Was about the only way to get enough PCIE connectors for the cards and risers.

I imagine your PSU is pretty close in specs to mine. Toughpower 750w but I have the Toughpower GF1 750w version and I've gotten a reply from Thermaltake Tech Department stating I wouldn't have any issues with just using 2 cables to connect to all 3 8-pin connections on the 3080 FTW3 Ultra. However, since my GPU can provide 3 separate 8-Pin cables, I went that route with my sleeved cable kit. Now I'm just waiting for the step-up que to notify step 2.

Intoxicus There is a reason they're doing 3X8pin. If they could use 2X8pin they would.
You're basically making 2 outputs feed 3 inputs beyond the output's capacity. This can results in melting cables, fires, damaged hardware, etc. There is indeed a reason: Each 8pin input socket is rated to 150W max. But that does not mean you definitely cannot use one output of the PSU to feed two GPU inputs. That depends on the cable rating and on the PSU's internal design – read: How many power rails does the PSU offer, is every PCIe output of the PSU fed by a different power rail or does it all come from one, how much power can every rail deliver etc. For example I do own a Corsair TX650M, which has two separate PCIe 8pin outputs, but only one 12V power rail internally. So, as long as I do not exceed each cable's power rating, it's rather a cosmetical question whether I use two cables with one 8pin connector on the GPU each, or just one cable with two daisy-chained connectors. But to give a simpler answer: As long as you're using the PSU's original PCIe cables, you're on the safe side. If the manufacturer provides with you with a daisy-chained 8pin plug, that means the whole assembly must be capable of handling the full 300W. Simple as that.

Yeah, I saw that post from ASUS on reddit and that's actually what sparked the idea that I may be able to get a FTW3 instead of an XC3 ultra. From my understanding though, the ASUS cards aren't using power from the PCIe slot whereas EVGA are(I think). If I can split(I guess this is the correct term instead of daisy chain), I will get a FTW3 and then buy a new psu in a month or two. Someone said on reddit that the split actually draws more power from the psu, though not exactly double, so it may be possible if that random guy on the internet is correct, which he most certainly may not be.
That being said, the ftw3 drawing 450 seems like a different deal compared to the ASUS cards, so maybe I should just stick with an XC3 Ultra.
Best practice is to use separate cables for Each 8-pin .... this became the recommendation of PSU Mfg with the 20 series cards
That said - Ask your PSU Mfg if they recommend it .... you risk damaging the PSU socket - even if it "works"
Stability could be affected 
Exactly correct. If in doubt contact the PSU manufacture. The issue people are having in general here is: MOST as in almost all PSUs 750W and below don't have enough PCIe cable ports coming from the PSU end to run 3 separate cables for the 3X slot cards. So both with the recommendations by both Nvidia and EVGA saying that PSU of 750W or higher is recommended is causing some issues. Combine that with people under recommending PSU wattage for the 3080's and 3090's and that will and is creating a lot of issues. Then there are some PSUs that are having problems with the 3080's and 3090's creating even more problems. All of that said: It is best practice to use separate connections from the PSU to each of the power connections on the GPUs. I have a Corsair HXI 850 PSU so I can monitor the power draw from the PSU to the components. (NOT FROM THE WALL) Actual max power draw from the PSU on my system below is 692W, that's loading both the GPU and CPU so the 3080 FTW3 Ultra is pulling every bit of 420W+.... That's not including power spikes that are much higher...

Yeah I know, I saw that too. I contacted thermaltake anyway and the dude literally tried it and said it broke the psu. You do what you want, but I'm not gonna risk it. My queue spot for xc3 ultra is higher anyway so I'm going with that. Thermaltake psu's kinda suck so maybe Jacob assumes we have good evga psu s.

Chumenuik said earlier in the thread that he was using one cable per 1080ti without issue.
I know my 1080Ti pulls 260w during 100% gaming load. So I think using 2 cables with 3 connectors should work fine.

Mining is not the same as gaming, not even remotely close. Nowhere near the same power draw as when gaming...

jacob said you can run 1 cable with no splitter and then a second cable with a splitter to make 3
Yeah I know, I saw that too. I contacted thermaltake anyway and the dude literally tried it and said it broke the psu. You do what you want, but I'm not gonna risk it. My queue spot for xc3 ultra is higher anyway so I'm going with that. Thermaltake psu's kinda suck so maybe Jacob assumes we have good evga psu s.
All that tells me is I would never buy a Thermaltake PSU.
I know I'm never gonna buy one again. I'm thinking about replacing this one even though it works.

Iirc Jacob ran a 10900k (or 10700k) OC (might be wrong about that) and a 3080 on a 650w PSU. Not that he would recommend it but yeah a good PSU can go a long way. I have a Corsair RMx (or RMi can't remember, the one that has iCue support) so i'm not too worried about running a daisy chain. Might try to do a bit of undervolting, someone managed to get 70w less and almost no hit in performance so might be worth a try.
