Close call... 5090 Burnt Cable

[danc]

what GPU is that? alphacool block comes with thermal pad for the connector, lol if that gets burnt too.

 

[Frizz]

Update: Even while using the 12v2x6 connector I still have coil whine and 16pin still goes down to sub 11.7 ... so I changed to the octopus cable aka 12v4x8 and now everything is stable at 12mv exactly and doesnt go below 11.8mv at 600w and this time coil whine is completely gone really annoying to have to worry about this on this day and age.

The absolute best results is using the 12v4x8 adapter that came with the card.

Yes the thermal pad is for the backplate side.

It doesn't really matter whether it's an official cable or not, the Nvidia reddit has reports of both equally burning up with the 5090.

It's all fun and games until Nvidia denies your $2,500 card's warranty for user error or it happens just outside of warranty.

The connector is just trash.

Or when putting the card under a waterblock.

Sorry to hear that, wonder if it will also start the same behaviour after some time on that adapter, or does it really don't like cables.

At least you tidied them up nicely but to be honest at that point Nvidia might as well just put 4x8 pins on the card. It's bullshit.

Does warranty apply after you mount a waterblock to it?

Just give us 8 pins direct . And thanks man heres a photo of my new case just in case it burns down later lol.



If it degrades ill just need to source 10 of these octopus bad boys.

On my 5080 I needed 90 degrees cable as well, thankfully I have be quiet PSU and they sell that cable for their PSUs:

Not very pretty but so far no problems and I saw that 5080 can also burn.

Glad that your GPU still works!

I know that every cable can burn basically but well in case of warranty they cannot claim that I used wrong cable

Wasn't there someone on TPU with melted bequiet cables?

As a electrical guy the variation in depth of the pins in that connector makes me feel ill thinking about plugging it into a multi thousand dollar component.


For reference I was programming $14,000.00 GPS receiver combos and made sure my cabling was perfect cause one oops and the receiver alone was 12K

Lovely build! Let's hope it doesn't burn down.

I've also flashed my VBIOS lol

DAMN those sleeved tubes look good!

I've also flashed my VBIOS lol

Oh god whyy... the last time I've done that when I was tweaking a GTX 470

Thanks! Lost the skin on my fingers trying to secure those fittings onto the sleeves .

Ah Ive claimed warranty for like 1 thing in the past decade ..for fans too, guess my lucks starting to run thin

Like I said any cable can melt, it's just a shitty connector. Let it melt, it's official cable of my PSU manufacturer, I'll warranty the shit out of it if it does melt.

That's only a pic from the web. Checked mine when it arrived they all seem pretty the same to me, no variation in depth on both sides.

To be fair.. I also probably maybe reinstalled the card over 10-20 times AND to be fair.... the connector I used may have been slightly damp from coolant......

Done

Further more.. my card is now able to pass timespy at 3100mhz+ core clocks... it wasnt able to do 113+ on afterburner before now it does 220+

AND the coil whine is almost completely gone with the ezdiyfab cable the coil whine was super loud!

Some of those issues might be unrelated to the replacement power cable.

Interesting stuff

I still wonder why they didn't adopt a std automotive type connector?

Usually rated for higher temps and current.

A beefy card deserves a beefy connector.

They had many alternatives apparently they just happened to go with the sh!ttest one.

3rd party cables give your 3rd party problems

not for people from the 3rd world..

Good catch. That was a close one.
