graphics cards can create unbalanced loads on power rails in different circumstances, which can cause voltage increases and/or current increases on the power supply side. This causes wires in the power cable to overheat, eventually melting them and damaging graphics cards.

please stop tom's hardware.

can you please stop writing utter nonsense, when you don't have a clue about any of this.

NO, a graphics card does in fact NOT create unbalanced loads on power rails (note the rails here btw).

a graphics card has a single 12 volt block, that the nvidia 12 pin firehazards feeds into by the nvidia 12 pin fire hazard spec it HAS to be a single 12 volt plane and it can't be separated as buildzoid pointed out.

and the psu has ALMOST CERTAINLY a single 12 volt rail. it CERTAINLY has a single 12 volt rail feeding a single 12 pin nvidia fire hazard connector.

if tom's hardware is talking about the 6 connections in each 12 pin nvidia fire hazard as if each is a "power rail", then we are jumping FAR FAR FAR out of the actual definitions used in regards to psus specifically, so wtf is going on here?

so a single 12 volt rail is feeding the 12 pin nvidia fire hazard and because it is seperated FOR NO REASON into 12 individual pins, so 6 power connections, the garbage fragile shit can easily melt on either side at the connections themselves, where the plastic melts first in the cable side and not the psu or graphics card side. why? because the plastics on the psu or graphics cards side of the connector has a higher temperature, that it can take.

it is quite rare, that the wires themselves start to melt, unless again tom's hardware wants to redefine what "wires" means here and instead of it being the actual wires, that go from one connector side to the other, "wires" here now means the connectors themselves, which given how they phrased it, it certainly SHOULD NOT mean.

of course the article doesn't mention whether it does amp sensing per pin of the 12 pin nvidia fire hazard.
