^^ Dam those toxics suck down some juice eh! Im not looking forward to setting those up.. I was hoping to do 3 on a 1000w EVGA powersupply 4 would be sweetness!!!! I just saw a rig with a 1000w LEPA running 4 280x's!! I saw them in the show your mining rigs section of bitcointalk!

I even asked him, if he was undervolting and he said yes and with no problems... Clearly he didnt have the toxic editions!

I solved the problem - add 1 more PSU!
1200wt is not enough for 4xToxic at default configuration. Yes you can undervolt, but i want IT ALL! since OC is very good show for kh/s Smiley

Im trying to mine LTC.
Mobo is MSI FM2-A85XA-G43 and 4 video cards are 280x.
PSU is 1200wt (galaxy hof 1200)
Risers i have are all 1x-16x, trader told me that there is no any difference to use 16x or 1x for mining, but 1x is better for ventilation.
I did't know that i can connect 1x to 16x slot on mobo which is true Smiley

BUT, when i start mining system is shuting down (using BAMT 1.5 and cgminer).

I have Sapphire Toxic, wich is working great and have 1256 by default.
With 3 cards its working fine.

It is problem with 1x risers? I need power risers? They are to expensive due great deficit and 1.5 month of waiting.
