Hi guys
ive just been given a OCZ stealthstream 600w psu to replace the 500w stealthstream i currently have running in my system,and the aim of the exersize was to safely power another new upgrade namely the "radeon HD6790 "
my existing ocz stelathstream 500w psu was powerful enough ( just about ) and had 2 x +12v rails with 18A on each rail ... however with just one 6pin pci-e connector it wasnt enough for the HD6790,and allthough i could of used a molex to 6pin adapter ive never liked them and didnt want to start
the 600w OCZ stealthstream on the other hand has 4 x +12v rails with 18A on each rail .. and the last of the four +12v rails is solely dedicated to the 2 x 6pin pci-e connectors that come with the 600w ocz stelthstream !
so im presuming the 600w ocz stealthstream should be more than powerful enough for the HD6790 and from what some quarters have told me it may also be enough for a crossfire setup ( allthough i beleive a 700w psu would be better when running 2 x HD6790,s in xfire )
as you can see the 4 x +12v rails are capable of delivering up to 580w ... and on this model the pci-e connectors are dedicated to the 2nd +12v rail ...
is there any advantage to having the pci-e 6pin connectors on their own rail ? ..... and would this be any more stable ?
and overall how good is this psu for my current system ?
specs :
core i5 3330
8gb ddr3 ram (1333mhz )
gigabyte H61MA-D2V
Sandisk readycache (32gb)
1tb WD sata HDD
500w OCZ stealthstream ( upgrading to 600w )
asus GTX550ti ( upgrading to HD6790 )
many thanks guys for all your help !
