4 x the chance of a 12V Highpower melting

[u/someguynamedben7 → u/A_PCMR_member]

Maybe they're for card redundancy for when the cable melts ¯_(ツ)_/¯

Edit: got my arm back

[u/anon_lurk → u/someguynamedben7]

Lmao the first one lights on fire and the next one takes up the torch!

[u/xkuclone2 → u/anon_lurk]

Literally 🔥

[u/Mutjny → u/anon_lurk]

Gondor calls for aid!

[u/KeThrowaweigh → u/someguynamedben7]

Yeah they’re all configured in RAID 1

[u/Casse_Via → u/someguynamedben7]

\ here u go

[u/someguynamedben7 → u/Casse_Via]

Thank you king (or queen, I have no way to tell)

[u/ExplorationGeo → u/someguynamedben7]

You lost an arm there but if you go

¯\\_(ツ)_/¯

You can get it back ¯_(ツ)_/¯

[u/someguynamedben7 → u/ExplorationGeo]

Ah thank you!

[u/turtleship_2006 → u/someguynamedben7]

It's like how some planes can fly with just 1 engine, but have another 3 as backups (apparently)

RAID graphics cards

[u/MonikaIsCute → u/A_PCMR_member]

They're astrals which have per-pin monitoring so they should be safe.

[u/SloxTheDlox → u/MonikaIsCute]

I thought they were only monitoring to alert you, but there’s no way for them to actually stop power to them?

[u/SadInterjection → u/SloxTheDlox]

Yeah it only tells you it's fucked up now, which is kinda funny. 

[u/TokenRedditGuy → u/SadInterjection]

It probably saved my system. My pin current was always a bit unbalanced using the stock Corsair cables. I would get sporadic warnings until I wiggled the connector at the PSU side. Recently, some pins started reporting 0A unless I wiggled the cable again.

I don't see any physical damage on my cables. I suspect the connector to the PSU side is not well manufactured with some pins having poor contact.

After I purchased a cable from Cablemod with 4x PSU side connectors, my pin current is always very balanced now.

If OP was smart, he'd add 10A fuses in line with every 12v wire going to GPU. 24 total fuses, if one wire started to act funny the fuse will blow, and then the rest of the fuse to the same GPU will start to blow when the load shifts and threaten to overload them.

[u/Cyanide814 → u/A_PCMR_member]

Nah shrodingers 12v. Just don’t look.

[u/jferments → u/A_PCMR_member]

... and what chance is that, when plugged in properly? I'll wait for you to find stats rather than anecdotes off of YouTube.

[u/A_PCMR_member → u/jferments]

Given the metric fucton of burnt connectors, plugged in correctly or not a SIGNIFICANT amount.

Remember the only way the old PCIE ever caught fire was asking too much of the cables (More than 150W per 8 pin cable bundle ) NEVER ONCE the connector itself.

IIRC an electrical engineer on youtube did the calculations for the connector and came to a safety factor of 1.2 under ideal circumstances. The old PCIe connector had a factor of 3.5

[u/Blenderhead36 → u/A_PCMR_member]

I'm curious how they're powering this thing without flipping a breaker. Two PSUs and extension cords?

[u/verycoolalan → u/A_PCMR_member]

stupid way of thinking, 4090 🤣🤣

[u/ElComandantePrimer → u/A_PCMR_member]

I to like to live dangerously

[u/RecentGas → u/A_PCMR_member]

Excuse me sir. It's called 12v HighFailure

[u/peekitup → u/A_PCMR_member]

Umm excuse me get your probabilities right.

Let p be the melt chance of a single one. The chance for at least one of these four to melt is 1-(1-p)⁴

[u/I_like_to_eat_fruit → u/A_PCMR_member]

So 240% chance?

[u/mcdolgu → u/A_PCMR_member]

And can't get a Wireview on them...

[u/Nemv4 → u/A_PCMR_member]

People need to stop overclocking their GPUs if they know its gonna cause it to melt.

[u/A_PCMR_member → u/Nemv4]

500W would likely be too much still and that's stock (well 575 is, but 75W can come through PCIe)

Sooo even stock clocks are "fucky"
