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

    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?!

    I already demonstrated that you would be low on headroom.
    Add that to the reported spikes some 3xxx series users are reporting and I would be concerned.
    Buy a 1500W or 1600W and be done with it.
    I personally have a 1500W, it was expensive and overkill, but with a 10yr guarantee I knew I would get my moneys worth in the long run.

    getting a 1500 watt psu for his setup would be moronic.

    You have to consider my post with respect to the forum member I was replying to.
    He worries, a lot, I merely suggested a completely worry free solution.

    850 platinum or 80 gold plus and you're fine. 750 w is the minimum for these power suckers.

    Hi, I have Seasonic Prime Titanium 850w, I7 4960X and a ROG Strix RTX 3090.
    when benchmarking games like ACO, ACOD, System shuts down due to OCP
    I measured the wattage of my entire PC, results that it cant handle more than 550w ~ 560w is far low than supported by PSU. Its a shame, a waste of PSU that worked well since Jan 2019.
    What i had to do? lower my GPU Power Target to 85%
    I dont think powering GPU with one splited PCIE + Single Cable would matter, I have been using splitted cable all the time for my 1080TI, never had this issue.

    Use two seperate PCIe cables, can't be using a single pcie split on a 3090.
