type-5 12VHPWR 600W

[SlobbaN]

I've posted the same topic in the wrong board, for which I'm very sorry, feel free to delete the other one.

Hello everyone, I'm new here, just got my RM1000x SHIFT 1000W and saw that the cable only does 450W, hence 3 quiestions:

1. Is it the cable that only supports 450W or the psu itself? If I get a type-5 600W cable in the future will it deliver all 600W or be limited to 450?

2. Will this be enough for a 4090? Any indication the 50 series will be even more power hungry?

3, The 12VHPWR cable that Corsair are selling is type-4, the Shift series is type-5 cables, thus incompatible. Do people at Corsair plan on releasing a type-5 600W cable?

4. Why is it that they just put a tiny sticker saying that it's ATX 3.0 PCI-e 5.0 compatible? Looks weird to me, other brands have it written on their boxes, not some tacky sticker lol. Also the cable itself doesn't have 450W written on it, even though it's required. Has anyone actully checked that the SHIFT series is atx3 and pci-e 5 as it states?
 

Thanks a lot in advance, have a good day!

Why do you think the 12vhpwr 12+4 is only rated for 450W?  I’ve combed through a few reviews and no one seems to mention this and lists it as the 600W capable cable the spec requires.

I had the same question due to the following image (Note the sticker on the upper right of the box face):

Damn, the quality of the image was degraded but it says 450W I assure you!

Here is the site I got the image from were you can find a high res version to zoom in on the sticker:

1. From my research it's the PSU itself, but take it with a grain of salt. (I'll be contacting support Monday for clarification.)

2. Jayz2Cents says it's fine to power a 4090 but it won't OC due to the lower limit. If OCing is something you may do, this is not the PSU for that on the 4090 specifically!

i beieve J2C pointed out that only the 1200W PSU has the 600W rating

So it’s on the writing under the “ATX ✔️” part?

 

My problem with this is it lists the 12+4 as a 16AWG cable, same as the 1200W shift. It seems crazy they would manufacture two 12+4 cables of the same gauge with different power handling capabilities. That doesn’t make sense on any level. So it would need to be the PSU socket or internals. It still seems a bit odd to deliberately limit the power on two PSUs that share a lot of parts, so this feels like someone from a different department was picking stickers. The 1000W review you linked refers to it as 600W cable. Someone from Corsair probably should clarify. 
 

However, as a 4090 owner with a 600W VBIOS, I can tell you it’s great at using more power for nothing in return. This is a benchmark tool and even if you have a “600W gpu”, it’s still 450W at 100% power and it runs at 450W out of the box. You must overclock the power to go higher. If you are the type that likes to run gpu benchmarks or wring every last ounce of performance from your gear, then you should be shopping for the 1200W anyway since it’s logical you’ll be doing the same to your other gear.   A 600W gpu plus overclocked cpu leaves a thin margin at 1000W.

It may be the case, but the 850W have the 600W sticker on them as well! I get it makes no sense, only leaving 250W for the rest of the system. Corsair REALLY needs to clarify all this!

Yes, the 450W PCI-E 5.0 part.

Agreed as to all comments in paragraph 2.

Again, agreed as to the 1200W instead....which is what I just got home with. Cost me an extra $75 but I'm good with that for the full 600W! It was on sale for $30 off to boot.

I don't plan on overclocking anything, both my 11900k and soon to be 4090 Strix are gonna run in stock, I'm just afraid the current 12VHPWR cable isn't gonan be feeding it enough power.
