So, buy trusted brands from trustworthy sources for anything electrical. Junk replacement power cables which are using aluminum or even steel wire. There's cheap SATA connector using mold injection which can't handle their 54W rating. Poor cable quality isn't solely in the domain of this connector. The problem is cheap PSU may use 18AWG or even 20AWG. If the 8pin wiring harness uses 16AWG wire and is 50 cm long. Now a good quality unit normally uses a much heavier gauge wire than the spec calls for. SJEOW cords have an oil- and water-resistant insulation. SVT cords are ultra-flexible and as pliable as vacuum cleaner cords. They should have updated their wiring decisions accordingly. Cords with a 90 elbow plug fit flush against a wall outlet, so they fit behind machinery or in areas where space is tight. But they've had over ten years to adjust to the fact that there are GPU with a TDP of over 225W. Truck-Lite Pigtail W/Adapter 2 Plug 94932 94853 - Y adapter plug used to accommodate additional side marker requirements Designed to adapt with Truck-Lite. They may have been caught flat footed when the Radeon HD 4870 x2 or GTX 480 came out. 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. We design products to improve the safety of trailer connector wiring. However this advice is coming specifically from Seasonic only, saying that it applies to all of their PSUs. Sure Shim produces and manufactures trailer pigtail plug safety shims. 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.
