4080S 12VHWPR bend okay?

[EpiphanyNinja]

I just finished building my new system with a gigabyte gaming OC 4080 super. I'm using the 12VHWPR cable that came with my Corsair RM1000e PSU. The way I installed it is seemingly the least bend I could get. The cable was kind of crimped a little bit about an inch or two from the connector so I had to straighten it out and make it a more gradual curve.

 

Is the current curve okay? I know there are issues with these connectors and fire hazards.

That looks good to me   There is barely any bend to it near the connection.

Been running my manually overclocked RTX 4080 since November 2022 with a tighter bend without any problems.

There hasn't been many if any? reported incidents with 4080's causing issue. Its 320w compared to a 4090's 450w.

 

This is how mine is. I use the supplied cable with the GPU.

Yeah that definitely makes me nervous, I replaced mine really quick as its not the bend, but the weight pulling on the pins with them not making even contact is known to be the issue.

Really?  I am not concerned at all.

And I have unplugged and plugged in the cable at least 6 times so far.

Even when the theory was that some failures were due to the pins not getting even contact due to the plugs only having a couple of contact points?  The weight of those adapters can cause a spark gap on those contacts.

 

I tied my cables to the case to take the weight off the plug and still felt uncomfortable and got the proper PSU cable.  You can see how the OP has no strain on the plug like you do.

Mine clicks in fully and there is no gap at all even with some tension on it.

I'm not worried.

Its not just the gap, its the plug not being perfectly straight against the pins so it makes uneven contact.  This is what the bend radius thing is about, to keep the plug perfectly straight not being tugged.

 

I mean it might be fine, but the sheathing around the plug on the adapters makes it impossible to clearly see and it definitely puts more weight on the plug.

 

The Corsair Premium cables are even better, very flexible.

Sure okay.  Mine is straight enough in my opinion, I am completely fine with how the cable is.

Been like this since November 2022 and I have pulled 300w+ through the connector for a long time. Its fine.

Fair enough, I do suspect the problem is not nearly as common as some people seem to think as they would have been forced to do a recall if it was.  But given Corsair have really nice Premium cables, it seemed worth it for piece of mind.

 

Although in my case at least one of them is running 24/7 Folding@Home, so extra paranoia is justified.

Its a overblown in the tech media in terms of adapters affected. The amount of cables burnt is like 0.1% if that.

That being said, it is an issue when there is a fire hazard and peoples lives can be at risk due to house fires++, its absoluitely not something to take lightly.

 

I am however upgrading from my RM750i to the brand new Corsair RM1000x 2024 model that was recently announced.

Its ATX 3.1 and runs the new and improved 12v-2x6 connector.

I will of course use the cable that comes with the PSU, mainly for aesthetic reasons as I am buying the new Antec Flux Pro case when available here.

I'm a little disappointed, as ATX 3.1 means two crap plugs rather than just the single one.  It doesn't add anything useful from what I've read.  I actually liked that Corsair hadn't done this yet, although I guess there is nothing to stop you using the old cables instead if they did not change the pinout.

That GPU's design doesn't allow for a bend at the connector at all, more or less. Assuming its fully plugged in (the real problem), its fine.

 

Typically cards have the connector on the edge of the card which is where this is more of a concern.

The connector originally had a slight 15 to 20° Bend about half an inch from the connector. I straightened it out gently before plugging it in as it is in the picture of now. Is it of any concern that it was slightly bent near the connector and I straightened it?

 

As far as I can tell it's all the way plugged in now, I pushed on it quite hard, almost uncomfortably so to ensure that.

The design of the card prevents any sort of bending that would be a problem. Most cards are designed with the connector on the outer edge which is where its an actual problem, at least potentially.
