Can you help me here? I pretend to buy for now a single 980GTX reference card (26 cm lenght) and my setup is being holded by an Aerocool 600W PSU: i7 4770k@4.4GHz - aprox. 150W at full load I will keep 3 750Ti on the system - aprox. 200W at full load with overclock 980 GTX reference model (2x 6 pins) - aprox. 200W-230W full load with a little overclock?! 1 SSD only - low power consumption So we have: 150+200+200 = 550W-580W average I have the 2 x 6 pins free to use in the 980GTX, I am using other powerlines to feed my 2x 750ti windforces, I will keep one PNY 750ti (just PCI-e/no extra power needed) and sell the other PNY. Do you think my PSU will handle this or I will need at least a 850W PSU? Thanks You can enter your data here and you will get your approx. power consumption of the system: http://www.extreme.outervision.com/psucalculatorlite.jspThanks for the link, I will emulate it. Cheers

Another question:
Can I dedicate one PSU just for the 980GTX, let´s say a 400W PSU just for the GPU, 02 paralel PSUs is viable or it would gave me some sort of trouble/ stability issues?
Thanks

Doing so will mix current from both PSUs @ the GPU. That's pretty risky in my book. I suppose you can get away with it anyway, as long as you're using a powered riser, so that both external power + PCIe power are feeding in from the same (external) PSU.
You also need to look specifically at the 12V line on that extra PSU. A 400W PSU can very well be maxed out at 250W in the 12V line (which is what the GPUs really use), and with a shitty efficiency rating, you might just stress it that little bit too much.
Good luck! Disclaimer: Someone that actually knows these things is bound to make better judgement than me. Don't take my word for anything above!

First your 600w psu will not be able to handle the 550 -580w load. Most psu's don't deliver more than 80% of the given wattage for long term. So the common rule is to not exeed 80% of the psu capability. Of course you can have some good gold or platinum psu's that can hold up to 90% of the given capability but usually they cost top $. If you want to run a second psu on your rig you need to make sure that the gpu is not connected to the pci-e slot on the mobo. That would make it draw power from two sources and is just a ticket to a fried something. You can do this if you use either non powered risers or best imo to use usb risers. Hope this helps. edit: sorry I meant to say powered risers with the feedback cut instead of non powered risers

Myagui and Skarfur, thanks for the explanations.
That´s what I tought, mix up the PSUs might not be a good call.
I will move to a 1200W PSU instead and use one 750Ti and the 600W PSU to build another (low-end) RIG, must buy a sempron 145+AM3 mobo+4GB DDR3 1333MHz+HDD 500GB.
Thanks

I would advice you from the sempron and the AM3 structure. Contrary to what many people think, the cpu does matter. I have read countless posts of people having hashing problems with various coins which ended up being because they were using a sempron. I would advice you go get a intel mobo and use a G3220 or something similar. I have had very good experience with the H81-pro-btc mobo's. Have 12 of them running now without any problems, except the one I fried the first time I tried to use 2 psu for one rig ![Smiley](https://bitcointalk.org/Smileys/default/smiley.gif) If you want to set up the 2 psu rig its nothing you need to worry about if you use usb risers, power the mobo + 1 or 2 gpu's (both riser and 6/8 pin cable) with one psu and you use the second psu solely to power the rest of the cards (both to power the riser and the 6/8 pin). The main factor here is that the usb risers only transmit data through the pci-e slot so you don't have the change of some current feedback to the mobo like you can get with the other risers.

Sturdy and cheap mobo. If you will run multiple instances of ccminer then go with Pentium otherwise (for max 3 instances) Celeron will do the job just fine.(mining rig only) For combo gaming-mining you should go with core I5 or better and better chipset is also recommended like Z87 or better http://www.asrock.com/mb/Intel/Z97%20OC%20Formula/

Ok, acknowledged! I will stay away from AM3 platform, it´s just I can´t keep unused/"disabled" hardware, I must sell them or exchange for something usefull, it´s my philosophy. ![Cool](https://bitcointalk.org/Smileys/default/cool.gif) My supplier gonna try to exchange my actual 600W PSU and the 2 750Ti by PNY for some acessories...(i.e. Razer BlackWidow plus Oroboros mouse or some DDR3 GSkill Ripjaws or something like that). I´ve changed my "strategy", gone wild and already bought today two 970GTX Superclocked by EVGA for SLI plus an Aerocool 1100W PSU 80 Plus Gold .... and will keep my 2xGigabytes Windforces 750 Ti, made a deal with my supplier with a big discount and this friday - if everything goes right - my new setup will be online... I will test mining on the 2x970GTX overclocked as hell...I will keep you posted about the results if you like it and post some pics of the setup/cards on my Asrock Extreme 9 AC. 980GTX price here in Brazil is just ridiculous, almost 2x970GTX....just stay away from 980 ![Tongue](https://bitcointalk.org/Smileys/default/tongue.gif) Cheers

Running, sudo apt-get install libcurl4-openssl-dev should fix it. BTW, I've found that getting CUDA and display drivers working on debian is a pain. That's why I switched to ubuntu server. I even wrote a guide. https://gist.github.com/zcshiner/4b32980792d367222304

So far I can't get my 970's to use more than 79% power, but they're still mining about as well as my rig of 6 750 non-Ti's or a rig of 5 Ti's. Looks like the miners will need some tweaks to get them operating at full speed. I'm sure the usual suspects will be on it as soon as they get one of the new cards, but feel free to compile me some with newer computes to try out ![Grin](https://bitcointalk.org/Smileys/default/grin.gif) I would rather not spend hours messing around with visual studio again...

Someone can help with this, it looks interesting. This will allow more stimulation in development for the GPU Miner, hopefully we can get some people together to get a stable AMD and NVIDIA miner. There will be bounties available to go directly to GPU Miner development. Bitslapper and I will be working on the AMD version while I am hoping to get some people to help build the NVIDIA version.
Please contact me if you have any experience / desire to help in the Coinshield Revolution.

I was wondering the same, i am expecting it to be 2 Yup, 2. There was only room for 1 750ti underneath them so I sold my other one in my main desktop to my roomate. The Gigabyte gaming 970s are loooong, and they fit so close to the heatsink and sata connectors on my UD4H Z87 board that I thought it was going to short something out. It's currently doing this weird thing where the monitors wake up from sleep and it reorganizes the open programs on my task bar. It also is having a bluescreen in win8.1 when shutting down or restarting, so I think I'm going to wipe all drivers and try again. Maybe it doesn't play nice with that minor update they pushed out when the 750 is running 144.11 and 970s are 144.16. I'm updating my mobo bios to a beta one now too, so hopefully things are better all around after that, who knows. Was all fine until 970s went in ![Cheesy](https://bitcointalk.org/Smileys/default/cheesy.gif)
