wattage and pcp link please
oh and on the budget one please
Personally planning to go with a 750 watt EVGA G2/G3. However, why are you wanting to get CrossFire 480's? Are you getting the two cards now, or like me and just an incase of upgrading to a second one in future? If two right away, then it'd be better to get just a single 1070, but if like me then you're fine.
1new, the other one 2ndhand from a friend but still good with half price (he's upgrading to green team after buying for few month)
A good 650w to 750W should be enough.
And what is your budget? Since for some people 50$ is called budget and for others its 150$.
i'm considering CXM 650-750 but dont know if the bronze rate enough
The CX650M will be enough https://pcpartpicker.com/product/R2mxFT/corsair-power-supply-cp9020103na. Bronze is just efficiency it doesn't say anything how good or bad a psu is since some gold rated psu's are worse then some bronze rated psu's.
Also i see that the CX650M costs 80$ but for a bit more you can get EVGA SuperNOVA G3 650W https://pcpartpicker.com/product/9q4NnQ/evga-power-supply-220g20650y1 which is alot better.
