CORSAIR Announces Compatibility for NVIDIA 40-Series Graphics Cards

[btarunr]

CORSAIR, a world leader in enthusiast components for gamers, creators, and PC builders, today announced the wide ranging compatibility of its array of PC components with NVIDIA's newly announced 40-series graphics cards, including the revolutionary RTX 4090. From power supplies able to drive the world's most powerful gaming systems, to stylish and capable gaming cases and a huge array of cooling options and accessories, CORSAIR offers the hardware to power, house, and cool the world's most powerful graphics cards - the way they were meant to be.

The newly announced NVIDIA RTX 4090 promises a huge leap in performance, and the great news for PC enthusiasts is that CORSAIR's existing power supply lineup is already fully compatible with the new NVIDIA 40-series. While the RTX 4090 uses a new 12+4 pin 12VHPWR power connector, all cards will ship with a PCI-e 8-pin power to 12VHPWR adapter. There's no need to wait for future PSUs to support Intel's new ATX 3.0 standard and CORSAIR's power supplies already provide the needed reliability and quality components to support the higher power needs of the next generation of PC hardware. Whether it's an RM1000 that's seen many builds, or a brand new HX1500i, you can depend on your CORSAIR PSU to power your graphics cards into the future.



Additionally, customers can now order official CORSAIR 12VHPWR 600 W cables compatible with all CORSAIR type-4 PSUs, connecting directly to the PSU via the existing PSU-side connectors for unfettered power straight for your new graphics card - no PCIe adapter required. With sense-wires configured to 600 W, your graphics card will know it's able to draw its maximum power load.

For those looking to start this new generation of PC hardware with an entirely new build, CORSAIR has an incredible range of multi-award winning, industry leading PC components around which to build your next PC. Whether it's a case to house your build in style with plentiful cooling such as the stunning iCUE 5000T RGB, a CPU cooler to envy such as the H150i ELITE LCD, or high-performance state-of-the-art DDR5 memory, CORSAIR has the hardware to complete your build and push its performance to the maximum.

The Hydro X Series XG7 4090 FE total-conversion waterblock will be available in November 2022.

For those who see stock as the starting point, CORSAIR is also readying a complete range of Hydro X Series XG7 total-conversion waterblocks for the new NVIDIA 40-series graphics cards. Nickel-plated copper contact plates, high-density cooling fins, and a full-coverage aluminium back plate help turn to squeeze every drop of performance from NVIDIA's new performance powerhouses, while a transparent acrylic top plate and integrated RGB lighting powered by iCUE software up the style stakes. Available in early November for Founders Edition RTX 4090 cards, Hydro X XG7 series waterblocks unlock the full potential of NVIDIA's best when combined with a full CORSAIR Hydro X watercooling kit such as the XH305i RGB PRO.

revolutionary RTX 4090? you means its revolutionary power draw and revolutionary large cooler?

 

[vatcar]

Maybe OP can explain this to me. So pci-e slot gives you a maximum of 75W. This adapter uses power slot's from PSU witch are supposed to be 150W each. So 75w+150W+150W= 375W
Even a 3080ti have 3 power ports (450W+75W)
How can i draw 660W from this cable to GPU?

 

[clopezi]

What would be the difference between the Corsair cable and the one that comes with Nvidia's RTX 4090, for example? Because let's assume that the Nvidia cable is not bad either, right?

Looks first of all, and probably on the same quality as the rest of their cables.

This is a cable, not an adapter. The new cards will have an adapter included, not a cable. If your question is whats the difference between an adapter and a cable, well the cable that corsair is advertising here is one that starts from your psu and goes directly into your gpu.

Readed on Reddit: The connector end on the PSU is rated for more. On corsair type 4 PSUs the PCIe connector and CPU connector are interchangeable on the PSU side, and the 8 pin for CPU can push up to something like 400w per connector.

Yes, you are absolutely right

This is not 150W 8-pin, this is the PSU socket 8-pin, the one that you connect your 2x8-pin cable to. It is 300W in theory, and multiple times that in reality for good PSUs.

 

[mama]

So, a CPU cable (300W) in place of a common 8 pin cable (150W)? Sorry my maths is bad, but does that mean 2 CPU cables give 600W to a GPU? It's not clear to me if this is true why these upgraded cables are not more common. Why is this not something offered by other PSU manufacturers?

In any event, two or more cables look ugly IMO. The community needs to embrace the single connector for modern PSUs.

It looks really short

Because not all PSU's have the CPU and PCI-e cables interchangeable. In the other hand, not all PSU's have the Corsair quality.

you can get 600w with only 2 wires
if a psu has only one rail it can deliver all its power in a single 8 pin connector
good ones are wired with 1,5 mm2 (16 awg) that its more than enough
i dont know max wattage for the connector, but i dont think that 600w are a problem for a well built connector

I call Bullocks on Corsair for this announcement and I hope I'm wrong.

1. The ATX 3.0 standard requires a PSU to handle a 2x total Power Excursion (PE) and 3x GPU Power Excursion to meet the standard. Corsair has simply suggested purchasing an overpowered PSU (RM1000 & HX1500i) instead of purchasing a PSU that is rated for the new standard.

2. "With sense-wires configured to 600 W, your graphics card will know it's able to draw its maximum power load." It might just be a Photoshop oopsie but looking at the image of the PSU cable, there are no wires connected to the 4pin portion of the 12+6 connector. There are no sense-wires. Maybe I'm missing something but from that image, the max power draw would be 300W (150W+150W).

Again, I'm hoping I'm wrong or missing something and someone here can turn the light on for me.

the rm1000 its a single rail unit it can delivery more that 600w with a single 8 pin connection.

This. Well.. actually, 348W @ 11.6V, but still... more than the 12VHPWR connector is rated at (considering it's twice the number of conductors).

It's going to take a lot of time to set you straight on these points. Can I grab a couple cups of Joe first?

You mean the connector that's melting on the PSU side?

It's good practice to use separate connectors than one big one if you're going to plug into a tight space like inside a PSU shroud. For one: 8-pin has better bend radius than 12-pin. Two: current causes resistance, resistance causes heat. It's better to spread that heat across terminals that are farther apart than concentrate them into one tiny connector.

So you're saying I don't need to throw away my brand new AX1600i if I get a 4090? Just buy this cable? Nice! Corsair FTW!

Yes please. What am I not understanding?

someone mentioned that they think Corsair may be using the EPS connector at the PSU, which has an extra +12V line but then how would you plug in the Mobo since this cable uses 2x connectors? That just doesn't seem right.

It seems like JTC has the same concerns with adapters.

EPS and PCIe are the same connector. Only keyed differently. Think about that for a minute. ;-) Why would keying a connector differently make it provide more power. Why would adding two sense pins to make a 6-pin into an 8-pin suddenly double it's capability to deliver power?

It seems like JTC has the same concerns with adapters.

JayZ has issues. Can't even do his own research.

1. Corsair made no claim that this cable has anything to do with ATX 3.0. ATX 3.0 is not PCIe 5.0. PCIe 5.0 is not ATX 3.0. PCIe 5.0's PCIe 5.0 specs are included in ATX 3.0, making it a subset. But that doesn't make them one in the same.

2. I think you meant 2+4. And there are two wires. And they're terminated to ground. Because that's how the GPU "knows" what cable you're using.

So I just ordered a 16 Pin Micro-Fit to 4x8-pin PCI-E Cable for NVIDIA 4090 600W from cablemod do I need all 4x8pin connectors for my hx1500i? Did I order wrong? Did I only need 2x8pin?

It depends on what they use for wire and terminals. If they use standard mini-fit jr. connectors and 18g wire, then you probably should use all four.

In talking with the Cablemod guys, they crimp a 16g wire in the 12VHPWR and then split each one into two wires after that wire comes out of the 12VHPWR. But I don't know if they're using 16g or 18g after that split, and I wouldn't want to take the chance of using half of the 8-pin connectors and putting double the load on one connector and none on another, so if it's made to use 4-pin, you should use four 8-pin.

 

[Wired Hardware]

Good question. I want to purchase this cable from CableMod as well for Corsair AX1600i. Would I need to connect all 4x8 pins? And is it safe?

It's safe... if you connect all four 8-pin connectors.

I just watched jonnyGURU's interview on YouTube with eTekNix. Here's the link:

It is a great explanation of why the worries about the new connector are overblown.
