okay, I'm feeling super stupid right now, looking for the cable to plug in my brand spanking new RTX 5080.

Here's my corsair PSU:

Here's the cable I bought from amazon that I thought would work:

Looks like the ends need to be Type5 not PCIe but I can't seem to find that cable (3 Type5 ends)?

Did a quick search to see if there is an adapter for PCIe to Type5 = here

I feel like I'm missing something really obvious... super tired right now and not seeing it...

Thanks,

V

Type 5 uses micro-fit connectors, a physically smaller size than mini-fit connectors. I bought the 850 a while ago not realizing it had micro-fit connectors. It comes with 2x 8-Pin from PSU to 12VHPWR which is configured as 600W yet box has sticker stating 300W or less! Well using 250W TGP card so no problem but 5080? Did your card come with adapter for 12-pin power and 3x 8-pin connectors? Wonder if it would be safer to buy 3 type 5 PCIe 8-Pins although I'm not fond of daisy chaining either.

that's actually a bit confusing, as here is a cable that shipped with the RTX 5080,

which I also dont have cables for and could work if I could find type5 to type5 cables...

That cable is an adapter to connect "regular" 6+2 PCIe power connectors.

That adapter is okay ,preferably using 3 individual PCIe connections rather than daisy chained connectors (which should actually work, TBH). Just my preference to use with a VERY expensive GPU.

However, the direct cable is better.

Noted, thanks...

Will go your route... I owe you a beer... 😎

Not according to Corsair. The original cable has two connectors on the PSU end. As does the cable linked above.

Hey COLGeek or anyone,

Quick question, did you find something that specifically shows what Corsair or NVidia recommends for cables(s) for the RTX 5080?

Looked through your above link and could not see any reference to the RTX 5080. also, google searching I could not find anywhere that had recommendations for cables to use for powering the RTX 5080.

thanks,

V

Lets put everything in one place.

A 'squid' adapter that came with the card is as follows.
One 8-pin input = 150W (These really don't exist, cards will just use a single 8-pin)
Two 8-pin input = 300W (5070/5070Ti)
Three 8-pin input = 450W (RTX 5080)
Four 8-pin input equals 600W (RTX 5090)

12VHPWR is designed to push 600W. Standard cables from Corsair offer two 6+2 pins coming from a single 8-pin connector at the PSU side, or 300W max per cable. So two connectors at the PSU end is all you need to run up to a 600W card. Your card is not 600W, only 360W stock.

Your PSU uses Corsair Type 5 cables.

So the Type 5 12VHPWR / 2x6 cable is all you need to hook the GPU up.

nice summary Eximo, thank you very much...

so, I'm assuming if it runs through 2 cables its pulling more current per cable, so a 2 cable setup running at 450W or 600W would need to have a higher gauge wire to handle the extra current, is this correct?

what about in terms of smoking my card as mentioned above, do some suppliers switch around the pin configs, or are all/most of the cables held to the same standard and pin configuration?

Yes, a thicker gauge. Which they already have been using for years.

hmm, interesting, I would think they would design the 2 cable setup to suit the cards per your above,

One 8-pin input = 150W (These really don't exist, cards will just use a single 8-pin)
Two 8-pin input = 300W (5070/5070Ti)

These are probably a lot higher sales too, so I would think they would want to have a smaller gauge to match these lower power cards so that the cable is as cheap as possible (optimized). Otherwise you might be selling, say 10% of your cables to the higher watt customers and then have the cables be more expensive then they needed to be for the other 90% (just making up numbers based on what I've heard about sales, RTX 5080 and RTX 5090, which don't sell much compared to the lower watt card)...

just my 2 cents,

A cable that is listed as Corsair Type 5 compatible should be fine, though I must say, none of the usual places seem to have any.

Anything else, and no. PSU makers have no obligation to stick to a standard at their end. And as mentioned, there is no guarantee that 3rd party manufacturers will wire it properly.

Corsair seems to be out of all their Type 5 inventory. I would reach out to them directly.

The lower end cards don't ship with adapters. They would just plug into the PSUs cables directly, as you also should be doing if you had the original cable set.

The PSU maker doesn't know what you are going to plug into it in advance, so their cables simply offer two 8-pin at each end, you only need to use one, or split it to down to a single 8-pin, or an 8-pin and a 6pin.

Yes, cheaper power supplies often use 18 gauge wire.

wholly crap, I've searched high and low for this cable (Corsair, amazon, BestBuy, Newegg ...etc)... and no one has it. Damn I waited 7 months for the card to finally come down in price where I got it fairly close to MSRP and now I can't find the damn cable!! grrrr ... yeah, yeah, I know first world problems right...

I could probably patch something together with splitters and adapters but would sure like the direct cable...

anyone know where else I might be able to find?

thanks in advance,

Vanz
ps. I can find a lot of Type-4...
