Question 12VHPWR (PCIe 5.0) cable for Phanteks Revolt X PH-P1000PS, how many 8-pin (PSU side) needed?

[moyang_mm]

Hello everyone! I own a PH-P1000PS PSU. I recently purchased a NVIDIA RTX 4090 graphics card and I would like to buy a 12VHPWR cable. I am not sure what is the right cable to use for my PSU. I know PH-P1000PS is made by Seasonic, so I am looking at this Seasonic cable. However, it only has 2 8-pin PSU connectors. I am not so sure my PSU can safely supports 600W over 2x 8-pin (I know some PSU can). Should I buy a 16-pin to 4x 8-pin cable, like the one made by CableMod instead?

Really appreciate your inputs!

You could just get this;

and they state it to be compatible with your PSU;

The new cable is compatible with our AMP and Revolt series PSU above 850W output.

Out of curiosity, how old is your PSU?

Thanks for the link! The cable looks very similar to the Seasonic one: both have 2x 8-pin PSU connectors..

I bought the PSU in early 2021 from newegg. Does age matter?

If the unit was old and was in use for a while, I'd heed caution since an aged PSU or one that's been heavily taxed or even both but in a dusty/dirty/hot environment will degrade the PSU's ability to output power effectively.
