PSU certification company Cybenetics, Aristeidis Bitziopoulos attempts to replicate the melting 12VHPWR problem by subjecting a cable to 600 watt loads for more than 90 minutes. He is unable to damage the cable.
Ronaldo Buassali of TecLab.net.br attempts to force an 12VHPWR adapter failure by subjecting it to a stress test of 1,532 watts —well beyond its rated sustained wattage of 600 watts. The adaptor did not fail. Buassali concluded that the connector is “well sized, so much so that it supported much more than its specification".
Stephen Burke of Gamers Nexus tries to replicate a failure by intentionally damaging a 12VHPWR adapter and subjecting it to a 99 percent load for 8 hours. No melting was observed.
Jon Gerow, director of R&D at Corsair posts results from intentionally damaged 12VHPWR cable adapters under load and is unable to induce melting. Despite breaking off solder joints, he was unable to induce a failure. Gerow concludes that some of the problems may have occurred when the owners didn’t fully seat the 12VHPWR adapter cables.
Gamers Nexus’ EIC Stephen Burke concludes debris inside the connectors from manufacturing or from insertion as well as improperly seating the cables is largely behind most of the failures seen...
