Questions about potentially upgrading to r9 290 crossfire.

post #1 of 10
Thread Starter 
I've recently been thinking about getting into cryptocurrency mining, and have been contemplating selling my 780 ti and picking up a couple r9 290's. I've never used AMD before or multi card setups and I had a lot of questions.

My main concern is what kind of temps I should expect. I won't be getting the reference cards for sure, I will probably be getting a couple MSI gaming or Sapphire Tri-X cards, unless you guys think I should go with another version. Do you guys think a Phantom 410 will have good enough airflow to prevent heat buildup from a couple of these cards?

Also, will this 850w psu be enough to power 2 of these cards overclocked and an overclocked 4770k?

Last I was wondering how good/bad crossfire is for gaming. I have read a lot of conflicting opinions about it. If any of you guys who are running similar setups could share your experiences it would really help me make a decision. Just wanna know what I'm getting myself into before I make a purchase.

Will you overvolt the cards too? Or, will you leave the 290s' voltages at stock?

Yes, I will overvolt them.

Oh. Then this 850W PSU won't be enough for sure. I think that it would be best to go with a good 1000-1200W PSU.

Thanks, any recommendations? Are there any good ones around $200? If not I'll probably keep them stock until I can save up a little more money. the 850w should be enough to run them at stock right?

The peak wattage per GPU would probably hit 350~400W though this is typically just for a few milliseconds at a time. Nominal wattage rates for stock/mildly OC'ed 290s (non-X) hover around 200~220W. That can be seen here: http://www.tomshardware.com/reviews/radeon-r9-290-and-290x,3728-4.html

If you're planning on running them balls to the wall overclocked 24/7 and running them with max usage expect to use a 1000~1200W PSU as TwoCables mentioned. Source: http://www.tweaktown.com/tweakipedia/37/sapphire-radeon-r9-290x-tri-x-overclocked-power-consumption-numbers/index.html (Yes these are 2x 290X's but a 290 is pretty close).

running them with stock voltage, yes 850w is sufficient. more than sufficient. ive tried silverdtone 750w, r9 290 crossfired, stoc voltage, 4770k oced to 4.3. run heaven, valley, 3dmark. i even try running occt full psu test. well it survive. well that was because it was only 2 days after i got that psu so thats why.

Yep! You might even be surprised by their performance at stock too.

 

I'm a little too far out of the loop to know PSUs in that wattage range, so the best that I can personally do is show you this thread:

I believe the EVGA SuperNova 1000G/P2 are some of the best you can get, especially for under $200. At least they both were under $200 the last time I checked. The Cooler Master V1000 is usually a good option as well.

Thanks guys, I guess I will just overclock them as much as I can on stock volts until I can afford a bigger psu.

Edit: Anyone have any idea what the heat output will be like? I haven't been able to find any benchmarks with people running 2 open air cooler cards in crossfire in a case. It's pretty much a deal breaker if the top card is still gonna be running at like 95C or something.
