So probably in the next 2 weeks im gonna buy the PSU EVGA 600B(45)dlls on amazon, so my question is if it is enought for a GTX 970? and if it can with a SLI?
I'd start off by not buying that PSU. Overall it's not a good unit as there are better available at that price. For most systems a good 450w unit would be enough for a single 970 and 650w is recommended for 2 in SLI. For a more accurate size recommendation we will need the full system specs.
