Xfire RX480

Can Corsair RM750x PSU handle 2xMSI RX 480 8GB ( @stock MSI clocks ) with i7 6700K @4.6 GHz ?

I tried Coolermaster's site and on maths it can handle it even on full load and 24/7 usage. But what's your opinion ?

No problem whatsoever. You can run 4x undervolted RX 480 and i7 6700K @ 4.6Ghz if you wanted to.

12V rail alone is rated at 750W.

I would caution against running RX 480 CF if you haven't purchased the cards yet because a single GTX1070 OC sounds like a better deal for gaming for the $. However, if you intend to mine with the RX 480s, then I suppose you can make a case for it.

Thanks russian for the fast reply. I am happy that I wont face any problems at all. Anyway, my budget is limited for now so I can buy msi rx 480 or gtx 1060. And I will go with amd (after 5 years with nvidia and no problems) just because I have the option to spend 200 euro next year and xfire the little beast. Also, planning to buy 1440p or high freq 1080p free sync which comes cheaper than gsync.

I'm very happy with my reference RX 480 and my 6700k at 4.6

People say this all the time and its just not a good idea. In 2 years it will make 10x more sense to just replace the 480 with something modern at that time. Crossfire is super spotty right now and the future is still very uncertain in DX12 as to adoption of mGPU tech.

Yep!

Only way it would be worth it to CFX / SLI later on is if you have two similar machines and thus already have two cards, and then take both of those into a 3rd machine when you upgrade the other two.

CFX and SLI have had very poor support for games in the last few years due to how game engines have changed. DX12 MGPU will help a lot once developers start using it, but so far it hasn't been worth it for them to spend the time developing for it.

Sorry but I just do not believe that in a year or probably 2 years, there will be a single gpu that will give me more power I will get from a used RX 480. Keep in your mind that we talk about ~150 Euro for used RX480 in a year from now and please do not compare the price range in 2 years.
I believe that both companies do not want to give their technologies too fast on the market. For many years they were on 28nm with AMD rebranding stuff and Nvidia which was winning on Dx11 bringing nothing but just more power efficient products. Nothing really new, no risk for the companies. Dx12, Vulkan are risky. See what really happened on Mantle. I like the way they shrinked their dies but I do not believe that for 2-3 years we will have something cool except HBM2.

Anyway, my point of view is that in a year with 150 Euro I will get a nice boost on performance when the 150 Euro GPUs will still be less powerful than a single RX480. However, the thing that you are really on point is that the mGPU setups may not be supported next year ( As developers care about them less and less every year ) . When the time comes I will decide if I will sell my RX480 and plus the 150 Euro budget I will get ~300 Euro GPU or just go for the XFire setup. Anyway, thanks for your opinion and sorry if my manners look bad, didn't want to be rowdy. Peace

No. You wont. You're not getting it. CrossFire doesn't even work in some new DX12 titles. It doesn't work in some DX11 titles, and when it does work, it's usually 6 months after release. I have a 290 Crossfire right now and I can't wait to get rid of it.

Besides you didn't even read what I wrote. You dont just buy a new card, you sell your existing card and upgrade to the newer card in 2 years time. You dont hold on to the old 480. And I can tell you with 100% certainty if you have ~150 euro for a used 480, and you instead take that ~150 euro and add in the proceeds from the sale of your existing rx480 you will 100% certain be able to buy something more powerful than a single 480.

But go ahead and get something worse for more money, not my problem.

^ From what I understood, the OP will buy just a single 480 upfront. He is not discounting the possibility of selling the 480 for 150 Euro, adding 150 Euro and buying a single fast 300 Euro card in 2 years. It seems he just wanted to know if hypothetically he could run RX 480 CF.

As far as your 290 CF setup goes, it should not be too hard to sell each of those for $150 and find a GTX1070 for $340-360. 1070 OC ~ R9 290 OC CF / R9 295X2 @ 1440p. It would be a cheap upgrade for you. Or you could wait until 2017 as 290 is not going to lose much value. Maybe save up a bit and hope for 1080 level of performance for $499. That's another option.

Sure you can Xfire with the RX 480 but most reviews of the Xfire RX 480 (there are not many reviews) recommend a GTX 1070 instead.

By the time he is financially ready, Vega should be out.

Honestly, unless Vega is some surprise, it's probably best for an RX 480/1060 owner to skip 2017 GPUs entirely and upgrade in 2018 with Volta/Navi. 480/1060 should easily last for 2 years at 1080p. seeing $650 980Ti/Fury X drop to $325-350 over just 18 months is sure to question the value proposition of $650-750 Vega/GP102 cards in 2017. It was pretty eye-opening for me (and $700 780Ti -> $330 970 in just 10 months the generation before current one). Imho, unless gaming at 1080p 120-144Hz, 1440/4K, by the time 980Ti/Fury X's performance was actually justifiable/warrantied, they literally dropped 1/2 in price and even then a $340-389 1070 is preferable to both. Why is Vega/GP102 not going to be a repeat of that?

I am somewhat doubtful we will see true next gen PC games in 2017. Even XB Scorpio won't be out until late 2017, which means we should start to expect next gen PC games by 2018 at the earliest. I could easily be wrong but I am not seeing anything impressive for 2017 yet besides Star Citizen. Red Dead Redemption 2 isn't even coming to PC in 2017 and since we already had BF1 this year, that's done too. I doubt CDPR can release Cyberpunk 2077 by next year after all the delays with TW3 and given how ambitious Cyberpunk is. Other games such as Dishonored 2, Civ 6, Watch Dogs 2, Mass Effect Andromeda do not look like they will push current gen cards that hard.
