I just brought this rig
CPU: Pentium G3250
M/B: Biostar H81S2
RAM: 4GB DDR3
PSU: Superflower Leadex Platinum 1200w
GPU: RX480 8GB Ref x 4
Riser: Ver 002 x 2 , Ver 003 x 3, Ver 005s x 4
Right now, only 2 GPU is working. One is directly put via pci-e 16x and another one via riser ver 005s
1. When I try to attach 3rd GPU on M/B via riser ver 002 and ver 003, my PSU won't run (fan and light just run for 1 seconds and stop). Is it riser problem?
2. When I try to attach 3rd GPU on M/B via riser ver 005s, my rig can run but 3rd GPU wouldn't show in device manager and also in GPU-Z. Is it also riser problem?
3. Is my PSU is ok for handle these 4 RX480 and also up to 6 RX480?
