Hello all,

I've go a GA-P35-DS3R with 1 PCI Express X16 slot and 3 PCI Express X1 slots (http://www.gigabyte.com/products/product-page.aspx?pid=2543#sp)

I plan to buy 3 r9 390 and connect them on it with a 1700W Lepa MaxPlatinum

is it a good idea / start ?

thank you in advance

no first off the mobo is really old

but I question your choice of cards more then anything

380's or 370's are a better choice

also do you own that psu?

it is multi rail

rail 1 20 amps >>>>> will not cover the 390
rail 2 20 amps >>>>> will not cover the 390
rail 3 30 amps
rail 4 30 amps
rail 5 30 amps
rail 6 30 amps

the 370's use 1 wire and will not overload the psu.
