Hi Bathrobe, thanks for your quick response again. I have a biostar tb250-btc pro motherboard and psu is silverstone 1200-pt. With 1200w and platinum 600w from wall before adding next card, it should go to 750/1200 used, should be able to work right or i am doing something wrong yet again.
Kind regards,
D
It should work, yes. If you replaced the risers and swapped cards around (to see if one card is faulty or whatever card you try to use as the 6th) then I don't know what could be wrong. It could be a BIOS option or a faulty PSU but both of which is unlikely.
