So i got this card 1 week ago and it was running smooth till yesterday, it was actually running so good that i was playin witcher 3 ultra for like 9 hr sessions and max temp would be 68degrees.. i was really happy with it..


Today when i woke up in morning however there is no display when i start my computer but the GPU RGB is up and fans running too and i have tried several stuff already out of desperation to make it work.

1. reset bios.
2. resinstalled windows too(i know too much)
3. tried my gtx 750ti, and 560Ti one by one to see if Slot is gone but nop the slot is working just fine.
4. the 560ti uses 2x6 pins so power is probably right too...
5. power for 480 was 6+2 , so i thought maybe the 2 is fucked so i went out and brought 2x6 pin to 1x8 pin connector and still same thing no display on screen..
6. finally i went to the shop for replacement and they said they will test it so i was standing and watching and it absolutely ran fine there...


Now i am back home with almost nothing in mind atm what to do , i think it might be my SMPS, or motherboard but icannot pin point at all since other 2 GPUs are running fine and this was too before yesterday.

What power supply are you using make and model? It worked fine at the store but not at your house? That doesn't really make sense. Have you tried a different outlet on a different circuit in your house? If it worked at the store I doubt anything is wrong with the power supply or motherboard.

Make sure your BIOS are up to date. Make sure you have onboard graphics turned off.
Also what PSU do you have?
Also what motherboard?

my powersupply is a local one 600W back in time i didnt thought of getting a good one, but it was indeed running this same card for 6 days, but since yesterday it doesnt give display but runs card, right now as i type it my gtx 560 with 2x6pins works on it. and same with 750ti so i think motherboard is out of question or the slot but power supply i think it maybe it too i am just looking if people think anything else could be problem too so i can be sure before purchase...

While we are at it any Powersupply you know off that would be good and long lasting

A local PSU Artis VIP 600W, Bios is not updated its F5 version, motherboard is B75m-d3h Gigabyte , i cant update bios because whenever i try to it says my OS isnt compatible, i guess Bios updates are not for windows 10 ,-, so sadly locked out on it too, but the gpu was just running fine last week

Older MoBo's tend to have outdated BIOS support and thus having issues to install the newest BIOS on win 10. However because your old cards work it tends to lean against the BIOS not working with newer Drivers for the card, if you can try using an older card driver version that still supports RX 480.
Also if you want a new PSU I would suggest EVGA 500W 80+ Bronze

I realised my bios had something called Qflash so i flashed it into new bios and it is working now the gpu is being detected and display is being shown again now, do you think i should still get a new PSU asap or keep it in my list and get it as i can

At the moment there is really no reason for you to spend money on a new PSU you might want to wait before you buy a new one.
