new psu for gtx 980 ti sli.

[chris78]

i currently have a xfx 850 watt psu, i was wondering if i upgrade to another gtx 980 ti in the future would this be okay and also if i did need a new psu it would have to be fully modular

Please list all components, this will help us determine system power draw

Edit: I also need to know the CPU

I have a question though... Why get a second 980ti when you could get a 1070/1080? Please be aware that not all games support SLI, meaning that some games will only use one GPU even if you have two. I always recommend getting one of the most powerful GPU that you can afford

I think that 850 watts will be enough for your purposes. Although I'm not sure about the quality of your PSU. I would recommend the Cooler Master V850 for your use scenario.

because i only just bought the gtx 980ti last year its expensive to keep upgrading every two years but i know what you mean lol

All of these would work for you. http://pcpartpicker.com/parts/compare/cooler-master-power-supply-rs850afbag1us,corsair-power-supply-cp9020093na,evga-power-supply-220p20850x1/

I do believe it's worth noting that I have had my Cooler Master V1000 for over two years now and I put a full load on it for extended periods of time and have never experienced voltages be more than .003 volts above or below where they're supposed to be. Because of this, I recommend the Cooler Master V series

the main reason i want to get a new psu is that i have had that psu for 4 years i like the fact that modular are neater and betrer for airflow, can you recommned me a good psu fully modular

your powersupply is a quality powersupply and can handle a 980 ti sli

Do you have issues playing games on the 980Ti?

Anyway, 980Ti draws around the same as my old GTX 570. I used to run two of them with my Phenom II x4 940 and I put a heavy OC on the CPU and on the GPUs, I was drawing around 720W. I moved from the PII to my i5-4670k (stock) and the power draw with the 570s around 600W (this was also with 2 HDDs, 1 DVD ROM, 5 case fans and a fan controller)

As long as your PSU isn't really old and is at least 80+ Bronze rating or better, you should be good running two 980s in SLI.

Your current Seasonic built XFX should be adequate.
