[SOLVED] Is my 750W-Seasonic Tx enough for Rtx 3090 without OC?

Hello. I ordered Palit Gaming Pro Rtx 3090. My psu is: Seasonic 750-TX PRIME ULTRA TITANIUM.

It will be ok?
cpu is 9700K,32 gb ram,1 sdd,1hdd


But according to Asus website ,no?

the 9700k is an i7.
even according to Asus' website it's enough

I read something that Ampere card can pull a huge amount of watts for a split second in games and benchmarks which can trip over current protection on psu's and many 750w units can fall foul.

Anyway should be ok?

the Seasonic TX is arguably the best consumer PSU available.
you'll be fine.

I read rumours that Seasonic Tx had problems with that cards. Its ridiciolous. The most expensive model of Seasonic and issues. Read:

View: https://www.reddit.com/r/nvidia/comments/j0t2ob/psu_concerns_with_rtx_3090/


"Linus tech tips specifically had a problem with a Seasonic TX-850W tripping its OCP at 50% power draw on the 3090, causing hard resets."


So change that psu for a i dont know COrsaiR?!

Depending on how short the transient current spikes tripping OCP are, Seasonic may be able to smooth those out by creating a special set of cables with in-line capacitors to smooth those out.
