    I just installed a 4090 less than a week ago. I was planning on upgrading my power supply only because I only have two dedicated connectors with pigtails. After researching the specs I decided to go ahead and run it. And I have had no issues. Plus I only play VR games and the 4090 so far hits 350 watts max on everything I have tried and less than 300 most of the time. I know it would spike a lot higher running ray traced benchmarks and the big ray traced flat games. I'm not worried at all about running pigtails for a while with the low power load I am seeing in VR. Personally I'd be good with 500 watts. Above that I might want to upgrade.

    • @mechitworks
      @mechitworks  Рік тому +3

      2 dedicated connectors would be really tight because of the power use from the 4090. If it only hits 350 its fine, but these gpu's will have short hard spikes. The reason it's not as great for the 4090 is because you have 3 layers of connectors instead of 2. the gpu, adapter and psu. Getting a custom cable for a psu would already be a big help.

    I'm a gpu miner and I used these with 3070 ti cards pulling around 250-260w of power in total (around 230w through one cable and rest through riser) using one cable like this, I managed to melt the psu side ports of 2 power supplies one of which was asus rog strix top brand psu. so the cable might be fine but the connectors are dogshit and can't handle 230w of continuous power. after these burns I swapped to using 2 separate cables for one 3070ti not going above 150w per cable, and haven't had a problem in 3 years.

    Question: 7900 XTX. I've currently got it plugged up to 2 8 pin PSU spots and it's got 3 8 pin ports on the GPU. I'm using a pigtail to handle that. TDP is 375 watts, which is fine. However when I started overclocking it'll go above 400 watts. Typically I would have said in the past no - 150 watts per 8 pin + 75 watts from PCI-E so 375 is the top. However, it appears it'll be fine according to this video? I'll still be well within Molex spec I believe.

  • @XxNewmilleniumxX
    @XxNewmilleniumxX 11 місяців тому +1

    It all matters if its muli railed or single railed. If its a single rail essentially the both of the tails are dc which means its split YES but its going into one current. Now if its multi railed you will have to be careful because it can overcharge one or the other tail and cause bsod/restarts and worst case scenario it can fry your pcie port directly on the pcie connectors and the pcie slot of the card. This when knowing and benchmarking your card to see if it spikes above 225W. Most psu's that are worth a damn are single railed anyways. Another reason to only go for certified gold only psu's, i.e quality psu's. Like EVGA, Corsair, Be quite, and seasonic.

  • @lullylew9083
    @lullylew9083 29 днів тому

    Read the manual of the PSU for the correct configuration for your GPU.
    Every PSU (Corsair, Be quiet, EVGA) I have purchased has either advised on 2 separate cables for cards with two 8-pin ports. Or has a warning stating that we should balance the load across the available two 12v rails also meaning to use two cables.
    Your card might look to be working fine with a single pig tail cable but it isn't worth the risk.
    I made the mistake of using a pigtail for a 7900XT and although it was working for several hours of gaming, I would get random kernel event 141 errors on light tasks. It was the PSU - GPU cable config that was the issue. Yes low draw tasks, weird huh? Don't take my word for it, read your manual. I think the PSU manufacturer would know what's best for the PSU they designed.

      @i_zoru Рік тому +1

      pigtailing should be fine, (not a good option, but a bit fine), i also have one, the only causes it will burn it because the wattage overladed the cable, if your GPU had to 1 8-pin and 1 6-pin, the maximum load should be 300W (include the wattage from yout PCIE slot on motherboard carried max power of 75 watt) so it'll be 150 + 75 + 75 watts in total, if you wanna go safer i suggest undervolting, it might hurt, but at least it will reduce the chances of power spike
      as long as your GPU TDP still around 50 watt below the maximum power of the system can provide, it should be good.

    • @dennislokerse
      @dennislokerse 8 місяців тому +2

      you are asking 2 questions:
      Can I safely connect the 6750xt using 1 cable with pigtails?
      Can my PSU handle transients?
      PCIe 8-pin connectors can supply 150 W (ua-cam.com/video/FfoT3qLH3rY/v-deo.html and en.wikipedia.org/wiki/PCI_Express#6-_and_8-pin_power_connectors), the motherboard provides an additional 75 W through the PCIe slot, so together that's 225 W. Since your PSU has only 1 PCIe cable, you're 25 W short.
      However, the problem is not power (watt) but heat. If airflow around the connectors is sufficient, you may not have a problem.
      As for the transients: I think you will be fine. Say a transient occurs during a few microseconds and asks the PSU for double the TDP, i.e. 500 W. The other components want some power too, for instance 100 W (depending on what and how many components you have). Together that's 600 W and you'll still have 50 W headroom.
      To be honest, if I were you, I would upgrade the PSU to 1 with 2 (or more) dedicated PCIe cables to prevent using a pigtailed configuration. Usually that means the PSU has more power too which gets you on the safe side concerning transients.
      Since you asked the question 8 months ago, I am curious: What did you do and how is it running?

    Anyone use the pigtail with a 4070 super?

      That's what I've been wanting to know lately. From what I've researched, the 4070 Super FE's total power draw is 220 watts maximum.
      So if I'm understanding correctly, then using 1 pcie daisy chained to gpu should be fine. Don't take my word for it though. Do some research and do what you are comfortable doing and or knows to work.
      It's also kinda weird nobody has put a video together showing exactly what kind of cable and how they are connecting gpu to psu regarding the 4070 super fe.
      Vury strange🤔

    No, they really aren't. That's why all of the major GPU and motherboard manufacturers recommend not doing this.

      Yee, use no problem. I have my rtx 3070 gaming oc connected this way from one year. Everything works fine in 100% load too.

    i have a MSI Radeon RX 5700 XT Gaming X Graphics Card '8GB GDDR6, 1980Hz and a 600w thermaltake psu that comes with 2(6+2)pin. is it okay to use the 2 pigtailed 8pins?

    • @onlyriderx
      @onlyriderx 5 місяців тому

      Yes, and it's the best, providing 300W of power to the GPU. But since it's an rx 5700xt, I think just one would be enough, depending on the model.
