    Default 3080 decimating my PSU

    I assumed my PSU would be fine and it wasn't so I am wondering if anyone can point me in the right direction.
    Anytime I put a load on it it will just crash and reboot. Seems to be a known issue with people. I used a friends extra PSU to take one of the 8 pins off my PSU and the computer hasn't crashed while stressing it.

    Intel Core i7-5820K 3.3 GHz OCed to 4.3GHz @ 1.25v
    Noctua NH-D15
    Asus SABERTOOTH X99
    Corsair Vengeance LPX 32 GB
    EVGA RTX 3080 FTW3 Ultra (was a 980Ti)
    Samsung EVO sata850 & nvme970
    3x WD Red 4TB
    SeaSonic X 850 W 80+ Gold
    3 Noctua case fans
    + mic, webcam, keyboard, headset, and mouse

    Live in the USA and would prefer not to spend more than 200, but would rather get something solid. My computer is pretty much on all the time.

    Thanks for any help anyone can give me.

    How did you connect the graphics card? Did you use three different cables? If not can you try that.

    I did use 3 different cables unfortunately.

    So, he is experiencing high transient loads and you think going down in wattage is a good idea?

    Yeah, it may be a failing specific to Seasonic models with low over power setting...But once burned twice shy.

    You are going to spend around $200 anyway for 850- 1000 watts....I'd go big and be done with it.

    Corsair also has 1000 watt units at newegg in this price range, RM gold and HX plat rated.

    If I am going to rewire an entire PC, I am going to do it once.

    So far there were very few units with transient issues with Ampere GPUs in addition to AMD Vega confirmed, Seasonic PRIME one of them, even 850W one. Sure, you can just go all-in and get 1kW unit in hopes that it wouldn't trip but i don't think it worth 200$ investment. If you just want to play safe, okay, here's 850W list :

    It should be under warranty still, I can contact them and see if that is RMA worthy.


    Thanks for all the other suggestions as well guys.

    What is it like without overclocking?

    It was more stable without the OC, I could load into a game, but it eventually restarted still at some point.
