I'm looking to upgrade my PSU in my 7010 MT.

It has a i5-3470 3.2Ghz, 16GB RAM (upgraded from 8GB), 500GB SSD (upgraded from 1TB SATA), WIN10 PRO

I have a MSI GeForce GTX 980 Gaming 4G card I would like to put into it. I know I will have to do some customizing to the case (remove the HD bay) and possibly create some more airflow.

I've seen some other posts that mention something about the power to the rails??? Also a post on here that says the only option is an EVGA 700BR because of that.

Just curious if that is for sure the only option or not for the GPU I want to use? I want to make sure I don't burn anything out in it before I do this. Trying to save money. Not looking to play the newest, fastest games. Just a simple upgrade to make it better for some games.

Thanks
