So I have 2 R9 290x in my main rig, I use it for many things and I HAD a 750w psu powering both, it would bluescreen when attempting to mine neoscrypt with Sgminer. So I decided to change it with an 850w psu I had and I am having the same damn issue, so what is the wattage to mine 2 r9 290x? I have some higher watt psu around I could switch it with, I just am not sure what I need to run it.
It's probably not the psu, however, i'm not sure what kind of psu it is.?
I also have 2 x 290x's running on a 850Watt PSU, mining 24/7 with no issues at all.
It's a Corsair 850RM version.
Knowing that a 290X can pull 350Watt at full load, multiply that by 2, it gives me 700Watt, so 150Watt for my mobo/cpu. it's close, but it does the trick just fine.
Check if your PSU is certified as 80Plus Gold, anything under that value will result in most likely failures and will also most likely not hold a constant power draw of that amount.
I have a feeling you're blue screening because you're setting your config settings to high.
Try with low settings first. It won't give you a blue screen then.
If it does, check for other hardware issues (RAM...)
