So I installed a new gpu(r9 390) on my pc a few days ago ( my old gpu was a gtx 760), then I connected the 6+8 cables from my PSU (cx600m), closed the case and started my computer.
But I noticed something different, a red light was appearing (under the CPU stock cooler box that comes with the Intel processors), I got worried cuz I knew that wasn't normal and the light was blue when I had my old system.
But even with the red light always on, no blinking, the computer seems to work fine. I tested it in games and didn't seem to have any problem, I even overclocked the r9 390 and the pc worked fine but the red light was always on.
I thought it could be from my PSU (cx600m) not handling the new gpu so I replaced the old gtx760 but this time the CPU cooler box was red not blue like it was before.
My doubt is: should I get worried about this red light? I searched for this on Google and it seems that when this light appears the pc won't boot, but mine seems to work fine even with the red light.
Is it normal?
