50 Series Question

[Apollyon622]

Hey everyone.

I'm considering to upgrade my 3090 to a 5090, whenever it gets released. My issue is, I don't have the cable to power the 40 series, and I assume the 50 series will have the same power cable? My current PSU is Corsair HX1000i. Will this cable work with my PSU to power the 40 and 50 series? https://www.corsair.com/ca/en/p/pc-...USyY4bnBRrpInr0W0YIz0lPKrCxEqr9Z3GgRZJCv0guS3

Also, my current rig is a i9 9900k and 32gbs. I assume my CPU still has some life left? My video card seems to struggle with some games running at 2k. Games like Alan Wake 2 runs like crap without frame generation enabled. DLSS doesn't seem to improve much unless I run the game on balanced.

Hopefully my current rig is fine and all I need to do is upgrade my GPU.

Corsair's website lists Type 4 compatibility for the newest HX1000i 2022 model. If that's what you have, then it'll work fine. Not sure which one is the "old" HXi but if memory serves me correctly that would have to be an ancient unit, with the early 2010s Corsair branding on it.

The cards come with a pigtail to convert the requisite number of 8 pins to 12VHPWR, so I don't see an issue or really a need for you to go buy an ordinary cable. I use the box adapter just fine with my regular HX1000, which is a couple years older than the "new" HX1000i. I use a Type 4 sleeved kit from Corsair - they probably include 12VHPWR with the kits by now.

On second thought, if the adapter presents some bending/curvature/clearance concerns, I guess the dedicated cable works better.

Yeah my HX1000i isn't from 2022 that's for sure lol . I may of built this rig back in 2018-2019 maybe. And got the 3090 the year it came out, which I believe was 2020? If the new cards are coming with adapters, then I guess I won't need to buy an original cable for my PSU. As long as the adapters work fine, I'll be happy. I was thinking of upgrading my CPU, but honestly I don't see why my i9 9900k isn't still powerful enough for the games coming out? Aren't the new games more GPU bound anyway?

I think Nvidia will eventually stop providing the adaptors, will it be with the 5000 series, no idea.

So your options are assuming the continue with the adaptor.

Use normal PCIe cables with the adaptor, on the 4000 series they require 3 of the cables for xx80 (up from 2 on 3000 series), I tried using 2 but GPU didnt power up. They tell you to not pig tail, you can pig tail to make it power up but Nvidia dont support it.
Use a cable from third party like cablemod provided you have one of PSUs they support.
Use PSU vendor cable that converts from old PCIe to the new standard (in my opinion this is best option if the vendor will support it, mine doesnt sadly).

If none of these you are happy with or cant do for whatever reason I think you would need a new PSU.

I think if there is an adaptor dont be surprised if they will expect you to use at least 4 non pigtail PCIe cables on the 5090.

My PSU cables are from Cablemods. Maybe I should contact them and see if they got the GPU 40 series power cable or adapter. I can't see Nvidia changing the way their GPU is being powered now. Especially when they completely changed it in the 40 series. Will they supply the adapter? I hope so. Maybe you're right and they'll stop supplying it. Knowing them, it's due to 'cost' lol.

I don't remember when exactly the new HXi released, but the old one should have a color label, not monochrome. I think blue was the HX color.

The direct cable that you linked is stated only compatible with PSUs that can take Type 4, which the old HXi isn't, but Corsair also says that the only difference between Type 3 and 4 is on the 24-pin. So it sounds like it should work, but you should ask Corsair about this directly for confirmation.

I did buy Cablemod's regular direct 12VHPWR cable ("sleeved") at some point, but did not use it as the "sleeving" was shockingly cheap and turned out to be a very different shade of white than Corsair's paracord kit, or even my old Cablemod SF custom kit. Electrically there was no problem.
