As I post my build below, I have another GTX 970 shipping to me, along with another 4k monitor. Obviously I've taken quite a bit of cash out and I really dont want too shell out more cash if I dont have too but I need to replace this Corsair CX500M 500w PSU for one that can handle my rig with 2 GTX 970's, at a decent price point (~$90-100). Can I get by on an EVGA 650W G1 for $79.99 (On sale) or an EVGA 750W B2 ($84.99)? Or should I shell out $120 for the highly acclaimed EVGA SuperNova 750W G2?

Go for the g2 750w. Way better and you should consider this because you have a beast system, the psu is like the heart of the system it pumps blood to the rest of the components in this case electricity do not cheap out get the evga g2 it is tier 1 and highly reccomended. I was mistaken as well and was going for the g1 until I found out that that is not wise and that I need to get te g2. Thanks to everyone who hated on me cause now I understand.

Is the 750 B2 any good? money is extremely tight now that I ordered a 2nd 4k monitor...

the 750B2 is better than the 650nex gold/G1 for sure.

Yes, I believe the only major difference is that it is 80+ bronze.

that's not the only major difference, but luckily efficiency is the least important factor with psu quality. there are units like this 750B2, antec HCG 750 and the silencer MKII silver that are far better than units like the CSM750, silent pro gold 600 and the NEX750G.

Yes, but anyways the 750b2 is a reputable psu and should do the job.

Take a look. The b2 is beastly. http://i.imgur.com/tgrbCnr.jpg

the wattage either way is fine. that's alot of money to risk on a poorly made unit like the nex650/G1. get the 750 B2 if you want a cheap psu.

Will it work? Probably. Would I recommend it? Not at all. The NEX/G1 units are meh as PSUs go. Not great, not terrible. The system will turn on and run, but you're cutting it dangerously close, and after a year or two as the GPUs begin to wear down and be less efficient, there's no guarantee that it won't end up causing a few shut downs. If you want a cheap unit that can run 2x970s, go for a 750 B2 or G2. The Enermax Revolution X't 730w is a good unit as well.
