You mean a defunct PSU review website, and a R&D Manager, not engineer.
Also, someone who has a history of using ad hominem replies to people in this and other forums if you go through his replies to others.
Not an ad hom but that is some sage crap advice.
2 feet of 18awg does not a lot of resistance make.
It's more likely a sudden system shutoff would be due to a PSU being overloaded in spikes, or thermal protection on the system.
But I digress.
