Posted December 27, 2017 Hi, i'm now using super flower leadex 2 650W gold psu. Will this psu be enough to power 3 gtx 1070? My setup is: Core i5 7500 Asus b250f strix mobo 16gb ddr4 1sata m.2 ssd 1 7.2k rpm sata hdd Link to comment Share on other sites More sharing options...

Posted December 27, 2017 No it will not be enough to power 3 of them if they are at max load. Also are you planning on using them in sli because they only support 2 way sli. I would recommend at least 850w for 3.

Posted December 27, 2017 1070 @ 150W max, x 3 is 450w. system consumption maybe another 125w maximum. SF is a good PSU brand known to not produce potatoes, you'd be running at near max, but on that PSU, i'd do it. not sure what you're doing with said 1070's but that's my rough math. I think you'll be fine.

Posted December 27, 2017 your b-series board will not allow multi-GPU usage (single only-lane configuration). 650 would be borderline at 100% load at 90% efficiency (230V not on 120V). 850 minimum for 3-way (if you get the driver key from nVidia). and not with your VS650 at all..

With little to no CPU load, 650W should be fine. From PC Perspective's testing, a 1070 will draw a bit under 150W under load. Under Furmark, Anandtech's 1070 system (the whole rig) drew 270W from the wall. Ignoring the PSU's efficiency (which would drop at least 20W from Anandtech's numbers), and adding 300W would total a bit under 600W under a GPU load. https://www.pcper.com/reviews/Graphics-Cards/GeForce-GTX-1070-8GB-Founders-Edition-Review/PC-Perspective-Advanced-Power-Te https://www.anandtech.com/show/10325/the-nvidia-geforce-gtx-1080-and-1070-founders-edition-review/30 :) Link to comment Share on other sites More sharing options...

Posted December 27, 2017 Author Yeah. I wanna use it to power 3 1070 for mining. Really hope that it will suffice. Link to comment Share on other sites More sharing options... Link to post Share on other sites More sharing options...

Really hope that it will suffice. then set the cards to 80 percent power, find a stable OC on the core, and +500 n the memory. System should not draw more than 500 watts.

Posted December 27, 2017 My system with two 1070's in SLI + 1700x Ryzen all OC mining was pulling upwards of 560 from the wall at times, usually settling down to 530 (+-5 watts), I mean i guess you can pull it off but just make sure you'r not running your CPU and you will be right at the max which probably won't be good for the long term if this is for 24/7 mining. Clock specs were 100% power, +109 on core and +500 on the mem. The short: Don't burn your house down lol.

Posted December 27, 2017 Mining with three 1070s myself (2x Asus Strix, one MSI Gaming X), and that entire setup is drawing 480W from the wall. I'm not mining on the CPU though, that would push me to 550W. Link to comment Share on other sites More sharing options... Link to post Share on other sites More sharing options...

No one is attacking you here. I'm offended you think i'm being hostile. Your results were not in good keeping with best mining practices. That does not invalidate your findings, but if you're going to give tips and suggestions on how his PSU will handle the power load for his application, at least present it from a full time miner's perspective.
