This is not a problem at all. The cable is rated at 600W, and the card can also draw 75W from the slot. I run a Strix RTX4090. I can draw 400-500W with the card over a long period of time without feeling any heating on the cable. I suspect that NVIDIA made the 4x so that you can connect the new card directly with the existing PSU + cable of the previous cards.

This cable is designed to power PCIe 5.0 graphics cards, but I don't have any specific information on its compatibility with 5090 series graphics cards. To check compatibility, we recommend consulting Corsair's power cable compatibility list or contacting the manufacturer directly.

Yes, it goes directly to the PSU. As long as you still have two free 8pin PCIe/CPU ports on the PSU, you can use the RM850 without any problems.

Yep, that's compatible

Hello and thank you for your question. Your power supply uses a type 4 cable. You can therefore use this cable. Best regards - CORSAIR Support

The cable is not intended for a mainboard, but for a 4000 Nvidia graphics card. What exactly are you looking for? If you want nice cabling, I recommend using the Extention kit from CableMod.

Is this cable compatible with the Bequit 1200Watt? Absolutely not, you need a black Be quiet cable: be quiet! 12VHPWR (60 cm) Look for it in white.

Normally, yes! I have an RM 850 2021 and it's running fine. You can check the Corsair website for more details => according to the web page = all good (https://www.corsair.com/fr/fr/s/psu-cable-compatibility)

Unfortunately, Corsair does not specify an exact length for the product. However, 12V high power cables are usually 65-75 cm long. The Lian Li PC-011 Dynamic should offer enough space for this. When laying the 12VHPWR cables, however, it is essential to ensure that they A: should only be bent from a distance of 35mm from the connector and B: the connector must actually be securely locked at the graphics card connection. It must not be possible to pull out the cable without pressing down the latch. NVidia recommends plugging the 12VHPWR cable into the graphics card before inserting it into the mainboard.
