ok 2nd psu worked just fine with gigabyte 5850 and 5770, but when i placed 5830 instead of 5850, 5830 xfx died..
theres no chance there was not enough power, so wtf happened,now when i put it in x16 system deasnt load at all, just vents working, and when i put it in x8 system works fine but theres no picture at all.
any ideas? sure hope i get replacement for that 5830
Ive had 2x 5850's that failed on me. Very strange problems like yours, Just wouldnt recognise them 2 cards in any mining tools or OC program with any configuration. Them 2 cards causes alot of fiddling about cause i didnt relise there was 2 faulty ones. Weird thing is they booted fine on there own but failed to initialise mining. Overclockers in the UK did actually replace them with that fault and confirmed it, which quite suprised me as the cards themselves worked fine with games or any other 'everyday' task
Check the AMP's your card is using and see if the PSU links up. 1 run 4x5850's all OC's pulling 100-120AMPS and my PSU's are 1200W @98Amps (ANTEC HCP1200) so it as a little overhead on the wattage and a little under on amps. Thats can damage hardware but theres not alot i can do about that. Dins a PSU that dishes out more than 100AMP, DOnt exist
Corsair AX1200 is the better supply by the tinyiest of margins though.
moral..... DONT BUY CHEAP PSU's, DO YOUR RESEARCH ON THEM, CORSAIR AX models, ALL OF THEM are the best CURRENT PSU's out there, imho and many others
