Yeah somehow I got an old revision Corsair HX1500i that did not include any 12VHPWR cables. So I ended up picking up the separate 12V-2x6 cable they sell for $30.

 

On another note, is there any reason to get a Power Conditioner + AVR for the system? I am used to running my systems through a UPS with those features but it seems like for high wattage they are only standalone.

 

Depends if you live in an area with unstable electricity or not. In areas with huge data centers maybe. It was a topic on the news earlier about this. Huge data centers in some places in US made problems for people living close to. Aka greater chance of early death for electronics. If you haven't had such problems before then the need for such tech is less.  Or non-existent.

If Corsair is selling it for that PSU it should be fine. 

 

No idea on the other question.

I think a lot of the Corsair units were sold as 2x8 Pin on the PSU side that went to 12 pin GPU cable. So, technically it’s not a real Gen 5 cable on both ends, if that’s what he was talking about. I personally think just a single Gen 5 cable on both ends will work well. No adapters, no 8 pins.

Nvidia have one of the best engineers in the world but still can't do it right. This is just sad. This tiny cute PCB is form over function bro @Mr. Fox Asus didn't have any choice after being the leader in melted 4090's. Hence they created a half baked monitoring solution.

You mean double up with tiny trash mini-fit connectors is the way to go? Nope. And even more important to avoid too much cable bends around the PSU panel. People don't open up their PC's one time a week for then open up the box shroud (often screwed down) that cover the PSU to look if everything is fine. 

 

Rather they will open up the box if they can smell some smoke. Then it's often too late.

That is exactly what you do not want, unless you want to replace the PSU and GPU. That is not what defines a Gen 5 PSU. If was probably a year after Gen 5 PSUs came out that the losers with dumb ideas started using that crappy connector on both ends.

You may have misread my post. 

 

I use this cable Gen5 to Gen5, no dongles, one cable. Never had any issues with my 666 watt bios since June of 2024 on my 4090 I run that dinky MSI 1000 watt Gen 5 PSU. It doesn’t even get warm. 
 

 

 

Corsair on the other hand, uses a retro fit dongle which is 2x8 pin to 1x Gen 5. 🤷‍♂️ Maybe I’m mistaken here. But I would rather have the single Gen 5 cable like the first picture.

Yep. On top you get double up with the tiny trash. I prefer the 2x8 pin to 1x Gen 5 and then forget what's connected to the PSU panel. It will sit firmly even with whatever bend needed until I remove it myself. Nothing is more safe to use than the old well proven 8-pins power connectors. And the hook and latch is triple size vs the new and modern. Aka can't get more secure connection🙂

Man, I don’t see the problem with it, even with no fans just open test bench and 666w bios. I have my cable bent slightly and it works wonderfully. It’s yellow on the plug portion so you know it’s plugged in all the way. It just works. Ran this with both 4080 Super’s and this 4090.

If it was so easy we would never have seen melted cards or melted PSU's🙂 And Northridge Fix and similar repair shops would have done something else than spend their time repair cards with melted power connectors every week. Because you don't see much of melted 8-pin connectors. They would instead spend more of their time repair failed Jokebooks.

 

Sadly, there is almost no 5090's to  buy... I expect we will see more smoke and fire once nvidia can push out more cards than the few houndreds they pushed out before the tax war.

 

Double up of everything has to be double the fun🤪

That looks like an aftermarket cable to me. I wonder how they are even plugging that cable in to their PSU at all! Its literally shorter than the 5090 is long 😆

 

Maybe they have an extension or dongle situation going on. @Papusan

 

I genuinely have never had any problems when using a Gen 5 PSU though. I’ve seen my card sustain 670W in Metro Exodus. I just cannot fault it, it has been perfect. 
 

I use the dinkiest cable of them all. lol.😂 Before this, I did use a 4x8 dongle. But I hated that thing, it was hideous. It Did not cause any problems either though.

8 pins each have a larger contact area, more space for cooling.

Unless you have a new solution with per pin sensing either side then it's not really an improvement.

That's the moddiy's high quality 12+4 pin cable😀

 

And please don't bash on the 4x8 dongle that follow the cards. That one, will often save the day for those screwed seeing voltage drop/ increaced resistance using their newer shiny high quality custom cables.

Exactly the same say all the screwed. It worked perfectly fine until it smelled weird in their room😀 And 5090 will pull 100W extra load compared to 4090. With the same cable. With the modern small PC boxes, expect many (pros and newbies) will twist and bend their cables in all ways to make it fit. 

 

Look at this bro @Mr. Fox Fantastic deal? Only 4000 Euro for the 5090. Here he defending the huge price premium because he was able to sell his 4090. 4000 euro = $4125 USD

nice, so basically he paid MSRP for the 5090 but also threw in his 4090 "for free" 😄

no way jose, im sticking to my 2x8pin seasonic cable specifically made for my PSU 🙂 dont want TWO potential fire hazards on one cable, one is quite enough 😄 

 

on this topic, i just ordered two new cables for my PSU with the updated 12V-2x6 connector. wanted to be sure to have those on hand before i unplug my 4090 for the upcoming storage upgrade / case cleaning:

But I’m just using a single Gen 5 cable though, it’s not like yours. Pretty sure @Papusan thinks my GPU will cook.

welp as with most things in life, its never black or white, but rather a collection of probabilities. anyone using the 16 pin plug is at "some" risk, but doesnt mean ure cooked for sure 😄 just gotta take the right precautions.

Got the 5090 installed but for some reason the performance seems to be limited. I left the VBIOS switch set to silent but I did not think it would make a major difference. HWInfo64 shows Rebar support inactive too.

Very nice GPU! You were so fortunate to have been able to get one congratulations. Did you notice the MSI US Store site always crashes when there’s a lot of activity?

It is not a given, only issue is doubling your risk by using the inferior and defective baby girl connector on both ends. If one end is going to melt, the lesser of two evils would be melting at the PSU. Subjectively speaking, the PSU end is probably more likely to not be seated properly or not stay securely connected and work loose compared to the GPU end.

I heard on a recent GN video and I think a der8auer video where sometimes the BIOS is getting switched to CSM mode automatically for unexplained reasons. Maybe that is why your resizable bar feature is turned off.

I will have to check that. Thanks for the tip. Although it does seem like GPU-Z says Rebar is working. Also its crashing again with a memory management BSOD so I am wondering if use of Gen5 requires more voltage on the rail for mesh overclocking stability...

People with 5090 have problem with PCIe 5.0. Try lower it to gen4.0 and see how it behaves.

Yes that too. Some people that were having black screens and the GPU  not detected found the problem resolved by setting Gen4 manually.

 

Gen5 seems to have too many caveats associated with it and it is an unnecessary technology that really has no practical benefit.

Defective, idiotic and failure-prone design that never should have seen the light of day. Everyone should be very angry with NVIDIA and blame them for all of the burned 4090 and 5090 graphics cards. This was seldom ever an issue with the legacy 8-pin connectors, and almost never seen unless you were pulling like 1000W through 3x8-pin, and even then very rare. Newer is always better newer. It's not who made the connectors, it's just a crap design no matter how you look at it.

 

1+1=2. 3x8=24 and 4x8=32. If you run 600W with a 12-pin connector with thin and aesthetically pleasing wires you're going to overheat things versus 24 or 32 wires. The imbeciles that thought this was a good idea had their head up their posterior orifice.  NVIDIA doesn't care and won't care until they come under legal assault and lose millions. The 4090 and 5090 should have a minimum of two of these or even better, scrap this stupid crap connector and go back to 3 or 4 8-pin connectors that have served us well since the day they were first introduced.

 

The winner here will be AMD. Not because they make a better product, because they don't. They will win simply because they were not stupid about this and didn't embrace popular stupidity.
