    My 750W Seasonic Ultra Prime Titanium has 6 x 8-pin PCI-E/CPU connectors. Of course it cannot supply 150W to each of those simultaneously. I am using 2 x8 to my GPU, and 2x8 to my CPU.
    You need a PSU with at least enough wattage to cover the simultaneous use. I think generally most OPSU above 750W do.
    Mine is a EVGA SuperNOVA 1200 P2 80+ PLATINUM

    So I see on tech power-up the TDP for the 3080 Ti @ 320W. - that is close to the limit of 375W for 2 8-pin connectors. They have it listed with a recommended 700W PSU and 2x8 pin PCI-E. 40 million transistors! That's over twice the 2080 Ti (18M). Now whether that is accurate we will shall see

    Hi,
    Done but pretty easy random drawing for a 500.00 micro center gift card and maybe 50.00 gift card
    Upload a couple jpg's of the front and the money side with rgb on and post your hardware

    Got both my x299 & z490 submitted yesterday and they're public now the ghetto..... on page one or switch to highest price sorting and scroll down a little kind of sucks they added everything up lol

    Drawing is on August 3rd sometime.
    Sign in and submit now.
    Builds : Micro Center

    Bro all the time i wasted putting my pc on there it's not on there wtf i am done
    that was too much time thrown away for it not to even be updated i seen your machines though good luck

    Yes the latest PCIe spec says 75W for 6-pin plug and 150W for 8-pin. That doesn't mean you can't supply more current with the same amount of cables.

    A 6-pin PCIe power connector had actually just 2 circuits and the 8-pin has 3.

    Each circuit is specced at max 4.16A but in theory you can supply up to 11A for each cable.

    That's almost 800W of raw power on 2x8-pin PCIe power connectors. This is however nearing the limits of the cables when you also take into consideration the temps in the case.

    That 4.16A per cable is a very conservative value because of safety reasons.

    Yes. A good cable can do up to 7A per circuit. But I know people who have gotten at the conservative limit on their CPU connector and burnt it at the motherboard.
    For a while some PSU supplied adaisy chained 2x 6+2 PCI-E that plugged into 8 pins at the PSU. That led to number of incidents.

    Lol, yeah never ever cheap out on the PSU and make sure your connectors are in good health and does a very tight fit. ;-)

    Think my PSU Currently goes with 6+2 PCie cable to 8pin at the PSU in my EVGA G3 650 watt power supply, with Intel I7 10700, and B460M motherboard. Not sure i'll upgrade to a 3000 series video card in the future or not, depends on if i can afford it

    Hi,
    Seemed pretty easy
    Only jpg images accepted I took all mine again I don't usually take any rgb stuff

    I see a lot of builds posted someone else assembled, a few by LTT and it was a business not personal so rules seem to be loose :/
    Hope you give it another try lots of amd & TR builds I was going to ask where your price range was.
    Heck 500.us MC gift card is worth a little road trip for a little on a new gpu @Dude
