Title: help - power supply question
Post by: PDcologne on January 07, 2014, 09:58:08 AM
hi guys -

am about to order parts for a new rig, and also add to my existing set-up.

question... my current set-up has 2x r280x... using a 650w be quiet. by adding one more 280x what power supply should i upgrade to?

second question.... the new rig will consist of 4x r280x.... same as above what power supply.

i have searched google and am getting conflicting answers to both questions so thought i would ask the experts...

thanks

PD

650 is the limit for 2
3 would reccomend 1000w or more
4 would suggest 1200w or more
