Im moving in closer to the day where I can upgrade to a GTX 1070 from a GTX 970. I previously posted a thread with some general questions regarding if my upgrade was possible and it seems it will be but now I have another question. The card I am using now is a ZOTAC GeForce GTX 970. It uses 2 x 6 Pin connectors. The EVGA GTX 1070 that I am hoping to upgrade too seems to use 1 x 8 pin connector.
I was able to find that the exact PSU I am using is a Coolmax ZX series 500W 80 Plus certified one. I know its not a great one but for a year its done me well. However the specs say it has 1 x 6-Pin, 1 x 6+2-Pin connectors. Will I be able to power my GTX 1070 with the 8 pin connectors using this? I've already made sure that it will not be using too much power (in fact from my understanding with the fantastic Pascal architecture the card uses it will use barely anymore power than the 970). I simply need to know if I can power the card with this. I am Guessing the 1 x 6+2 Pin connector would work? or must it be an 8 pin connector?
I would hope to not have to change the power supply as I find it to be the most tedious and annoying part of a build! Thanks in advance for your replies.

If the PSU has a 6+2 pin PCIe connector, that is what they mean by an 8-pin. Yes, use that.
The 1070 is only about a 5W greater load than the 970... all else being equal.
But that is an expensive card to be trusting to that low-end PSU.

Thanks for the reply. I am aware it isnt a great PSU but the way I see it is the thing has been going strong for over a year with no problems on an overclocked 970. I believe with my OC settings its running more watts than the base clock for the 1070 would anyway. Since its probably over kill for what I usually play I dont plan on overclocking the 1070 at all. Maybe low-end but certainly a pretty good little PSU for the price, at least from my experience.

Again, thank you. As I stated I am aware it isnt a great PSU. However I feel very comftorable after a year of pretty heavy use that the PSU is a solid one despite its reputation. Perhaps when I am going to get my GFX card and RAM i'll check if they have any better ones I could upgrade to for an affordable price.

Id also like to add that many of the negative reviews I have seen are either from DOA purchases of the PSU, life span, and some power cycling issues but most of all that the fan is too loud. The only experience I can share with others is that yes the fan is loud but otherwise I suppose I have lucked out!
