hola crees que ira bien con la rtx 4070ti?

Great video thank you, I just got my first PC build(used) and it has this PSU, i'm currently running: Ryzen5 7600 EVGA 3070FTW Ultra Looking to just upgrade my GPU to to the best I can get (maybe 7900xtx) I'm so confused with the power connectors, would I be able to run an 7900XTX from this PSU? as I think the XTX needs 3 power cables? Thanks again for the video liked and subbed

How many 8pin (or 6+2pin) pcie cables can your psu do? It is possible to connect 3x 8pin pcie cables to the gpu and ideally, each cable would be individually going into the psu - however, the gpu can also be plugged in using only 2 physical 8pin cables at the psu end - this would mean you would have 1 main 8pin pcie cable going from the psu to the gpu pcie 8pin slot #1, then your 2nd 8pin cable coming from the PSU needs it's main 8pin plugging in to 8pin gpu slot #2, then you just use the daisy chain 8pin from the 2nd cable (if your psu doesn't have 3x individual 8pin cables from the psu)

one of the gpu power 6+2 is on the cable so it has enough for a 4090 to connect to doesnt it? it may not be the recommended power but it should be able to connect?

Hi, Thanks for watching. Personally I wouldn't recommend using a 750w PSU with 4090 and would highly recommend getting a PSU which allows 4 separate connectors for GPU as this is the ideal setup i think. If you have a 4090 with only 3 x 8 pin GPU connectors, you could probably get away with a 850W PSU. Theoretically if you have a lower TDP CPU you could get away with a 750w with 3 independent connectors for 3 x 8 pin 4090 GPU's but again I recommend against this setup to accommodate for power spikes. Hope that helps, all the best, TK :).

Hello sir, nice review, i am interested in this psu and i watched a few videos and almost every video there is someone complaining about the psu noises, fan is too loud under load, fan rattling noise after a few months and even on the first weeks of use, is yours still working fine??

[@TKsTechTalk]

Hi, Thanks for watching. It certainly is still working ok, I have passed on the PSU since the video but I used it for about 2 months in this machine and it was fine, it is currently in use in a PC with 12900K and RTX 2060 12GB GPU, hope that helps, all the best, TK :).

@@TKsTechTalk It might have helped if it was a bit earlier 😁, i was interested on that psu because it is semi modular, and i wanted an EVGA one, was a good deal but no worries, I ended up buying a Seasonic one. not modular but it is 80plus gold. but thank you for your time and feedback 👍

I do have the same psu with a Ryzen 7 5700x and a 3070 ti, and 32 gb ram. Do you think Can I upgrade my graphics card to a 3090 and keeping this psu?

[@TKsTechTalk]

Hi, Thanks for watching. As you can see from my video it seems to work fine with the 13900k and 3090 under full load, so in theory it should be fine as the 5700x has a considerably lowerr TDP than the 13900K so you have extra headroom there. I guess there is a very minor risk of a random power spikes in certain games, though I think you should be ok most of the time as this is not a regular occurrence as far as I know. Hope that helps, all the best, TK :).

They’re actually capable of 1000 watts from what I’ve seen, they sell them as 750 watts. I still do not recommend it for anything that use over 750 watts though, theirs a reason for this.

Hello and thank you for your video. I want to upgrade my system. Currently, I have ryzen 5 3600 and rtx 2060 with EVGA SuperNOVA 750 B1 Bronze 750W as psu. I want to switch it into ryzen 5 5600x and rtx 4070. Does the motherboard and psu can overcome the stress. I have been using my psu like 8 years.

[@TKsTechTalk]

Hi Thanks for watching. I think the easy answer would be to just upgrade your parts and keep the PSU for now. I understand that the PSU you have comes with a 5 year warranty, though in most cases it should be fine to continue using it unless you have noticed any issues. Since you already have a system which uses well below the 750w PSU and you plan to upgrade to a CPU and GPU which have a low combined TDP i think you should be fine for now. I think there are 4070 cards which do not require the 12vhpwr and best to get one without it and your current PSU should be absolutely fine. As you can see from my video this 750w can handle the 13900k and 3090 though I would not really recommend using it with this setup as there is no headroom for power spikes, with your planned setup you should be ok. Hope that helps, let us know how you get on, all the best,TK:).

@@TKsTechTalk Thank you for answering fast as you did. I am thinking of buying Gigabyte RTX 4070 Gaming OC ver. Is it one of the models that you mentioned above? Thanks again for helping.

@@oguzhanserim8035 Unfortunately no it does not use a 8 pin connector, however there is a trade off here. basically the card you mentioned and like many others come with a 16 pin to 2 x 8 pin converter. Now I do not believe there have been reports yet (though its probably to early to say) about the 16 pin 12vhpwr connector melting on rtx 4070 cards, but there have been a fair number of reports on 4090 but that has a much higher TDP though we dont know for sure if that's what is causing the issue or as some people suggest to make sure the connector is fully seated properly into the graphics card which might reduce this risk. The trade off is that if you get a card with 8 pin connector you will be limited to a 4070 to about 200w TDP and if you go for 16 pin connector it can be higher TDP (around 225+) and maybe boost a little higher than stock, not sure how much performance benefit there would be. I'm not sure exactly which Gigabyte models if any have this but check out the article below it might help: videocardz.com/newz/gigabyte-rtx-4070-custom-gpus-to-feature-either-16pin-or-8pin-power-connectors Sorry I couldn't give a definitive answer but I hope this helps.

[@TKsTechTalk]

looks like eagle and windforce might have 8 pin but please check before buying and remember there will be a clock difference, check out the different models below: www.gigabyte.com/Graphics-Card/All-Series?fid=2860

[@TKsTechTalk]

sorry one last point i just thought about for 8 pin but looks like it's not an issue. typically 8 pin connectors deliver 150w power and the card can pull upto an additional 75w from pcie connector, so for a 200w tdp card this should be fine, the article below explains this www.tomshardware.com/news/inno3d-geforce-rtx-4070-to-come-with-8-pin-power-connector
