Safe to use two power supplies in case?

I was looking at this product

https://www.overclockers.co.uk/ocuk-professional-dual-power-adapter-24-pin-black-15cm-ca-198-op.html

Ive just ordered a 3090 FE, ive already tried a 3090 and was getting power issues with my single 750w psu, ive got a spare 750w seasonic that i can put in my case, is it safe to run just the GPU off another power supply? My case has space for the second psu no problem.

Any advice? Ive been unable to find a 1000w psu in stock anywhere to replace my two 750w seasonics with.

It's absolutely fine. Just make sure that the case can cope with two PSUs.

You got the cable to link them?

Yup, quite often done by extreme overclockers, no harm at all

I probably shouldn't say this out loud but there are some 1000W power supplies available if you order directly from Corsair UK. They actually ship from Amsterdam but are on 24hr free delivery.
