Question Is there any improvement using the 12v HPWR power supply from PSU to a PCIe 4.0 Graphics card?

[thexmen]

Having the RX7800 XT, which is a PCI e 4.0 graphics card, the power supply port on the card is 2x 8pin.

I notice the PSU, thermaltake GF3 1000W has a 12v HPWR port and it comes with the cable. I am wondering if it is worth to use an adapter cable to use the 12v HPWR power supply instead of the two 8pin connector?

Thanks.

Why add a adapter?
Just use 2 separate 8 pin cables.

Overall, it is not advisable to start mixing and matching cables and/or power connections without some specific manufacturer documentation supporting the connection or connections being made.

And if multiple components (i.e., your GPU and PSU) are involved then you must cross check before making any connections.

Bear in mind that adapters and cables can be generic, poorly designed, poorly manufactured, and just outright sub-standard.

Which could end badly.

Read the documentation.

That's something I am trying to find out if there is any advantage to use that new cable from PSU to Graphics card or just pure simplicity. It says 600W on the cable head, not sure if means more power supply or something else.

Any adapter adds another point to fail.

Use 2 cables from the power supply and connect the 8 pins to the video card or is that to simple?
