Question about Corsair Premium 12+4-pin 12VHPWR-600-W cable for PCIe Gen 5 with single jacket

Hi, the CP-8920333 cable is designed for PCIe Gen 5 graphics cards and can provide up to 600W. If your RM850 2019 can provide the required power for an RTX 5070 TI, the cable should work. Regarding the connector fusion, it is important to ensure that the connections are clean and tight to avoid overheating. Corsair has taken measures to improve the quality of its cables, but it is always advisable to check the connections regularly.
