Is my setup looks ok?

[maxik2000]

Hi,

I'd like to put together the following setup:

Asus Maximus VIII Hero
Intel Core i7-6700K
2 x 8GB DDR4
2 x GTX 970
2 x SSD
1 x SATA
1 x Bluray
and probably some Corsair watercooler (not sure which one yet).

My local store tells me that I need a 1000W power supply. Just wanted to make sure before I buy it.


Thanks!

he is right on this , but get a good quality psu like seasonic/xfx/evga b2-g2-gs

Well 970 sli actually requires up to 700W power but going for 850W is better. Anyways don't go for 970 sli, better a single 980ti, trust me will be worth it more in the long run.

I did some research and according to Nvidia, GTX 970 maximum power is 145W. With that, 2 of them will need 290W, CPU probably around 100W. The rest maybe another 200-300W. Why do I need 850 or 1000W power supply?

GTX 970 when combined with full system can run up to 500W, you must not go lower than this. The single gtx 970 itself can generate up to 250W at full stress, that's why 750W is the recommendation for SLI.

Ouch! 250W is a lot...

Yeah, higher-end gpus are extremely powerhungry. I mean it could be lower, most likely for your use-case it won't exceed 150W, but still you never want to risk an expensive SLI.

I wish there was a way to know power needs in case I decide to change the parts.

1000W look overkill a bit , but will last longer and safer depending of the price ??

SLI doesnt even properly work on most games so i really suggest you not to do that but like 980ti (6 GB) would be better if you want something over 4gb since gtx970 is a 3.5gb card so you will get about 7 gb (in something like DX12 otherwise just 3.5gb effectively for dx11 and below). And like i said Dual-GPUs has some nice benefits on paper but have almost little to none real use at gaming and such.

As for PSU go for EVGA, Superflower, Seasonic etc. Tier 1 or Tier 2 PSUs as you can check here http://www.tomshardware.co.uk/forum/id-2547993/psu-tier-list.html (1000 watts is totally overkill )
