The new GPU is powered on but not receiving any signal, while the old GPU continues to function properly?
Hey everyone, I recently purchased a lightly used Zotac RTX 2080 Blower to swap in for my older GTX 1660, but I’m still not getting any signal after installing it. When I put the 1660 back in, everything works perfectly. It seems the issue is likely related to the GPU itself. I’ve tried reseating the card several times, cleaned the contacts, double-checked the power cables (using both an 8+6 pigtail and two separate cables), but nothing changed. The card powers on, the fan spins, but I don’t see any signal reaching the monitor. The only other thought is that I might not be providing enough power, but I’m using a 550w EVGA Supernova 550 G2 PSU with an MSI B450 Tomahawk motherboard, a Ryzen 5 5600 CPU, and a few SSDs—according to most PSU calculators, that should be sufficient. I’d like to double-check everything before relying on the buyer’s protection and returning the card, if you have any suggestions. Thanks in advance!
What is the age of the power supply unit in your setup?
I considered only one option besides the card being damaged.
Have you tried placing the GPU in the lowest slot on the motherboard? The RTX 2070 was heavily used during a mining boom. Did you confirm the card was functioning before buying it?
Transfer the RTX 2070 to another functional system with a 650W power supply. If it operates there, your motherboard may require a BIOS update (if applicable).
I haven't tried it yet, but shouldn't I be fine if the 1660 model works in the upper one? My PSU is a few years old—likely 4 or 5 years—but it's never caused issues and still functions perfectly with my old GPU. Unfortunately, I bought it online and the seller assured me it was tested, but I have a 3-day buyer protection policy. If it's faulty, I can return it. It's a 2080, not a 2070, according to the seller—it came from medical equipment that used real-time AI and was never overclocked or used for mining. I don't have a 650W PSU to test it with, though my motherboard is already updated to the latest BIOS.
I can verify that the card continues to lack any signal when employing the alternative slot in the mobo. Is there really a possibility it's related to the PSU? Even if 550W is slightly insufficient for maximum power consumption, it should still provide adequate power to start up, shouldn't it?
The specifications indicate the GPU consumes 200W during spikes up to 240W, but likely only 10-20W at startup. This suggests it should boot and function under light loads, implying a possible fault. It may have worked initially but could have malfunctioned over time due to factors like static electricity. It might be a seller's issue, not yours.
Yeah, I guess there's not much else I can try. The box it came in also had a damaged corner and was slightly open - the seller seems completely legit and already sold a bunch of other GPUs without issues, so I'm thinking something happened during delivery and just borked the card, even if aesthetically it looks fine.
I'll send it back while I can, thanks everyone for the advice.
When attempting to boot the computer, does the GPU or VGA warning LED on the motherboard illuminate? Remove the drivers using DDU, update the BIOS to the latest release (excluding beta), and follow these steps. If unsuccessful, another approach that resolved a "no signal" issue after card replacement or driver changes was effective for me. Power off the system, then connect the card to the HDMI/DP port on the graphics card. If no signal persists, switch ports sequentially (HDMI to DP, DP to HDMI) and retry.
