It's happening again, melting 12v high pwr connectors

I guess if any of this dense 12pin cables want to sustain 600W for daily usage they should be build with 900W (+50% safety) max power ability and not 660W (+10% safety).

This is a good read, thanks.

What I suspected is indeed true, that nvidia went backwards when going from 3090 > 4090 and then again for 5090.

Pathetic.

In addition...

Who cares if such a cable will cost $50 or $100
There is a local old saying here that goes: "Silk underwear require silk asses too"

EDIT: typo

Nvidia: "Have fun with our product, which we totally did not rush out. Also, enjoy the new 12V-2x6 standard along with your new PSUs - we cunningly had a plan for this to go hand in hand with our new GPUS, so you never have to worry about 12v power cables and weak pin connections again."
