I don't know where the guy making that Youtube video gets the idea that high TDP cards are new. Better yet they should just use a heavier gauge cable which can handle the current of both connectors. There should be a warning listing max draw and fuses in the lines if the cable can't supply the rated current of both connectors. This is a failure of the PSU manufacturer. The problem is those dual connectors imply the cable is rated for 300W. Not unless PSU manufacturers make a new line of PSUs next year that gives us thicker gauged PCI-E power connectors to handle more current/wattage, some people can run into this issue where their PCI-E pigtail connectors could burst into flames.Ī single 8 pin PCIe power connector is rated for 150w. I wondering though if this applies generally to all other PSUs? Googling "PCI-E Pigtail avoid" seems that the issue is not yet made aware yet or hasn't been an issue at all. I have Seasonic PSUs so I will heed this advice. However this advice is coming specifically from Seasonic only, saying that it applies to all of their PSUs. This can easily be the RTX 3070 - RTX 3090 GPUs which have >225W power drawĪnd highly probably, Nvidia's next gen RTX 40 series GPUs (which are rumored to be even more power hungry than the RTX 30 series) You then have to use an additional, separate PCI-E power connector to power for every other slot on your GPU). if you have a 2x 6+2 pin connectors, you should only use one of them. And it advises to avoid using both connectors from a Pigtail style PCI-E connector if your GPU is rated above 225W (i.e.
