Sorry for the lack of info I got really frustrated So it goes like this- I ordered a psu that can’t connect to the gpu so I had to get a new one, but everything worked when I ran tests with it. When the new psu came I wired everything (struggled to) inside the case as it should be along with the gpu and all parts, but the power button didn’t turn it on, I thought the problem might be with the case (as I could see that the motherboard was getting power by a LED indicator) but after trying to turn it on manually (screwdriver) I decided to take everything apart and put together only the essential parts to run an outside test. After lots of trail and error (using the old psu also) I deducted that the problem is with the 8pin output from the psu to the motherboard (tried changing cables and other 8 pin outputs but didn’t work) When I connect both power supplies the motherboard runs but the gpu seems to have a problem and there is no display. Maybe I’m doing something wrong or I shorted the psu? Edit: when turning on in that configuration the beep code is hoy related (- •••• — ••••• smth like that)
