Computer fails to power on after the GPU upgrade?
Hi everyone!
I purchased a GeForce RTX 3060 GPU to replace my old GeForce 1650. Whenever I connect my 8-pin 6+2 pin to the computer and the PSU, nothing happens. If I leave the power supply connected to the GPU, the computer remains completely silent—no fans spin, no motherboard lights flicker. Once I disconnect the 6+2 pin and turn the system back on, everything powers up, but the computer still shows only power without loading. The white error light appears, suggesting a problem. When I reinstalled my previous GPU, the PC functioned normally, and the motherboard remained operational.
My GPU and all other components are properly seated. I also updated my BIOS after confirming compatibility between the B460M PRO-VDH motherboard and the GeForce RTX 3060.
Here’s a comparison:

I’d appreciate any advice! It seems I might need to upgrade the motherboard or upgrade the PSU to a higher wattage.

The screw beside the 8-pin power connector for the RTX 3060 seems questionable. If this card is used second hand, the prior owner might have removed the cooler and caused damage during reattachment. Based on the sounds, the PSU is identifying a short circuit in the 8-way PCIe connection when connected to the RTX3060 and OCP (over current protection) is activating. The system won't function if it detects no auxiliary +12V power on the RTX3060, which explains why you're observing a white light. It's likely your RTX3060 is non-functional. Apologies.
What is the age of the PSU in your setup? Have you experimented with connecting the new GPU using a PSU offering 650W of power, sourced from someone else's system (not just the advertised amount) who has a well-built unit?
Are you using the same GPU as before? Did you check if it was functioning properly prior to buying it?
I also refreshed my BIOS with the previous graphics card.
Did you reset the CMOS after confirming your BIOS update was applied to the most recent version? Regarding the BIOS, what version are you currently using?
The screw next to the 8-pin power RTX 3060 connector looks suspicious. If the card is second hand, the previous owner may have pulled the cooler off and made a mess of repasting it.
By the sounds of it, the PSU is detecting a short circuit on the 8-way PCIe lead when it's connected to the RTX3060 and OCP (over current protection) in the PSU is kicking in.
The computer won't work if it detects there's no auxiliary +12V power on the RTX3060, so there's no point expecting anything to happen with the 8-way PCIe lead disconnected. That's why you're seeing a white light.
Chances are your RTX3060 is dead. Sorry.
Please don't lay your graphics cards down on the brown carpet (at least that's what I think it is). Carpet is one of the worst things for inducing static voltages, which can zap your cards with ESD. Similarly, don't lay the computer case down on the carpet with the side panel removed, exposing the rear of the motherboard to possible ESD damage.
The international companies I worked for spent millions equipping their test labs and manufacturing areas with ESD protection.

Of course if you keep your fingers crossed, static damage will never happen, but it's better to play safe. Components damaged by static can work for months or even years after being zapped, before mysteriously dying.
Thank you for your message.
Your PSU is from 2017.
I attempted the two-step process of clearing CMOS, but the computer still doesn't work with the new graphics card.
The graphics card is brand new and has never been used before.
I plan to purchase a new motherboard, graphics card, and power supply.
Appreciate your assistance.
The new GPU might demand greater power than your existing PSU can supply. If your PSU falls short, you'll need to upgrade it for proper performance. Certain BIOS configurations may require tweaking to fit the new GPU. Reset CMOS: This action will reset the BIOS settings back to their standard values.
The specifications for the OP's CoolerMaster MasterWatt 650 should be adequate to supply power to the RTX 3060. https://play3r.net/reviews/psus/cooler-m...ly-review/ According to this review, my RTX 3060 with 12GB uses 170W during video rendering, which fits comfortably within the capabilities of most 650W power supplies. https://www.techpowerup.com/gpu-specs/ge...2-gb.c3682 Determining the precise model and production year from the OP's photo is challenging, but the MasterWatt 650 likely isn't the optimal 650W power supply available. It could also be past its warranty period. https://forums. It's unclear if this is necessary. The OP is swapping a GeForce 1650 for an RTX 3060, so the BIOS should already accommodate a PCIe card rather than the integrated graphics. However, there might be driver conflicts, possibly needing DDU support. https://www.guru3d.com/download/display-...-download/ That's helpful. It suggests the issue may lie with the older MasterWatt 650, even though it should theoretically provide the extra 100W needed by the 3060. https://electronics.stackexchange.c...ull-power-from-both-the-slot-and-the-external To summarize: Your previous GeForce 1650 was working fine on the PCIe bus. Your new RTX 3060 seems to force the MasterWatt 650 when connected via the PCIe 6+2 pin. I’m not sure, but it’s possible you’re using the wrong 8-way connector for the RTX 3060. https://superuser.com/questions/849...nc...connectors Please don’t feel discouraged—this could be a sign of your setup being flawed, though it’s possible with enough effort. I’ve seen PSUs where both EPS12V and PCIe outputs are unlabeled, so careful inspection is wise. If one connector splits into different configurations, I can confirm their purpose.
