Question No display except BIOS with second hand XFX RX 6600 RT ?

[mysteltian]

I just bought a second-hand XFX QICK 308 6600 XT from a dealer. I removed my old GTX 960 and install the new card. Things seem ok on the very first boot up but I do notice some strange lags when I switched between windows (like fps drops or something like that). While I was downloading programs and some benchmarking tools, the screen just went dark. I restarted the PC but the display did not come back up.

I tried restarting a couple of times and I noticed that I actually can see the BIOS screen. I also noticed that the GPU actually seems to be working 5-10 seconds after I press the power button. But right after the BIOS screen is gone, the fans just suddenly went off. I also managed to get the BIOS and not seeing any display problems during a couple minutes I check around in the BIOS. But of course display would turn dark right after I exit.

I am suspecting the PSU not having enough wattage, but it seems like my Corsair RM650 should at least get the card to operate under usual condition.
My current system:
- Motherboard: MSI Tomahawk B450 MAX
- CPU: AMD Ryzen 5 3600
- GPU: XFX qick 308 RX 6600XT (was using GTX960 for a very long time)
- RAM: 4 x 8GB Corsair Vengeance RGB pro 3600
- I have 2 SSD + 1 HDD but I cannot remember the model precisely. I can check if the info is relevant here. P

lease advise.

Was the card used for MINING before ? Was the GPU in a perfectly working condition when you bought it from the seller ? Where did you actually buy it from ? Your PSU is sufficient for this card.

Did the seller gave you any hint that the card was fully functioning properly before, or did he flash the BIOS of the card ?
