18 awg is max 7A which would put you at 100% capacity at 500W over 2 pcie connections

If the connectors can handle it without melting.
 
The issue is there is no enforceable standard on what they use.

The connectors are rated at 9A so 18 awg cable would melt before the connectors

Just for lol's I took a closer look at my electric kettle.
240V 3000W = 12.5A
The cable the plugs into the wall (via our max allowed fuse of 13A) is 1mm2, this cable seems to translate to 18 awg and the max current is being exceeded every time I make myself a nice cuppa.
 
Make of that what you will lol

Actually no, that's not true.
 
It's the pins that are the real issue, the ones in the connectors.
 
That's what heats up and causes them to melt.
 
I just talked to a designer on that exact subject about a 2 weeks ago.
 
 

The heat from the connector running at close to max current would only be an issue if the connection was poor, a cheap psu would be the biggesat contender for that, a premium one not so much, unless you are plugging in and out a hell of a lot to weaken the connections.
Your average end user unplugs the psu very few times over it's life and would also likely replace the psu before this becomes an issue.
The connections rated at 9A are likely a safe margin and would not just burn out as soon as 9A flowed through, much like cables.
 
Ultimatly the closer to max current you get, the greater the chance for them to fail.

So, my EVGA PSU came with 2 of these daisy chain cables.  They're not recommended for use by EVGA, but it's what they sold with the product.  Can I return these for single cables that aren't daisy chained?   I realize I could choose not to plug one in, but they're a fire hazard. I'd prefer just to replace them for a cable that isn't.  Can we get an official recall?
 
It seems pretty straight forward.  They are either acceptable for use and not a fire hazard.  Or they are a fire hazard and we get a recall with free cable replacement.  If EVGA isn't going to do a recall with free replacement, they are acceptable and not a fire hazard.  You cannot have it both ways.

Which PSU and GPU?  If you are not actually using it as a daisy chain, meaning plugging both the main and the piggy back in, then its not a fire hazard in the sense to what they are referring. Its not pulling a load from that unused plug. This whole thing is blown way out of proportion. A little common sense tells you that if these split cables were causing fires in PCs, PSU manufacturers would be pulling every single one and would have a disclaimer stating DO NOT USE THEM... and not.. we "Recommend".

That's the point he was making. He was being sarcastic. He agrees with you.

I have a EVGA 1000WG3 purchased directly from EVGA.com and a 3080 FTW3 ULTRA purchased directly from EVGA.com.   If EVGA does not recommend that anyone use PCI-E cables with 2x connections on them (daisy chain) due to risk of fire they should not supply them in the box.  Plain and simple.    An official recall should be opened with CPSC.GOV and the items should be replaced free of charge.   Now if EVGA says it's not recommended but it's still fully functional and not a risk of fire and burning down your apartment complex possibly putting hundreds of lives (including children, pets, etc) at risk, then that is different.   I know everyone hates the government but things like CPSC exist for a reason.
 
 
FWIW I think there is a reason why EVGA has not officially done a recall and is still selling these items to date.  They are fully functional and not a risk.   They need to speak with their employees and ensure that their employees are not making these inauccrate statements on behalf of the company in a public forum.
 
Regardless of which side of the fence this ends up on, EVGA is doing something wrong.  The topic of debate is what?  Selling a volatile product that should be recalled or allowing their employees to communicate inaccurate statements.

It’s also of note, EVGA does not make power supplies. They are OEM power supplies made to EVGA specifications, and rebranded, so if the OEM approves daisy chaining cables, then EVGA would fall back on them if there actually was a fire hazard. That would require proof of daisy chaining being the cause of a fire, and I don’t think I have seen anywhere stating this has happened before, so it would require testing.

The product is sold by EVGA with EVGAs name on the side.  They are liable.    Their staff states these items will catch fire.  if this is true, a recall should be issued.  What will happen if we wake up tomorrow and a fire occurs and children are dead?  I guarantee there will be an investigation and EVGA will be held liable for damages + restitution + pain and suffering when they KNOWINGLY allowed products that produce fires to remain in use without recall.

jankersonDoubtful it would start a fire if the PSU is a good quality unit.
 
The connectors are designed to melt not burn on quality PSUs.

I doubt it would start a fire either, but a company representative said this is possible.  This adds to the confusion of the consumer.  As a consumer, I am worried for my children now.  Would I be a good father if I wasn't?

jankerson The only ones I have ever seen burn are low quality junk PSUs.
 
Or old out of date PSUs that should have been thrown away long before they failed and started the fire.
 

Gals/guys we can debate back and forth the likelihood of it happening, but that is not the topic of debate here in this post.    The debate is what is the official standpoint.   The company representative has stated that their products if used will create a fire hazard.

jankersonI doubt they said will...
 
I remember they said could.

With all due respect, the potential for fire is a fire hazard.  If it created a fire every time, the situation would not be a hazard.  It would simply be fire.

Well all of the one who produce good quality PSUs and most PSUs in general these days supply them with Daisy Chained cables.
 
And that is across the board except for certain model that DO NOT.
 
As long as one does their research and follows the recommendations from the makers they should be fine.
 
The issue is all of the bad information and recommendations out there on the internet, well it is the internet... 
 
And even if they actually do any research at all before buying a PSU in the 1st place or even more thought than what LED lights they are going to use.

Several decades ago I worked for a web hosting company.  The owner of a famous website that reviewed hosting companies.  We showed him the data center and offices, took him to a fancy steak house and drove him to the state near by (he wanted to check that state off his list).  We signed an advertising contract with his website and he left.  Shortly there after we were top 10 on the website.  With all of the fake reviews, likes and up votes it's hard for consumers to decipher what is real.    If a company sold a product 2 years ago that is not a fire hazard a recall should be issued.
