I'm having trouble getting my computer to power on, and I'm wondering if my 400W power supply could be the issue. I've tested it with an i3 10100f paired with a GTX 1050 Ti and it booted up fine. I also tried it with an RTX 3060 Ti, and it worked without any problems. However, when I tested the i5 10100f with the GTX 1050 Ti, it booted normally, but it didn't boot with the RTX 3060. Is the power supply the culprit here?

A 3060 typically requires a minimum of 550W, so your 400W PSU might just not cut it if you want stable performance.
For a 3060, the recommended minimum is around 550W. Ideally, you should consider a 650W power supply, especially if you're planning any future upgrades like a more powerful CPU.
Got it, thanks for the advice!
Yes, that could definitely be a factor.
Ok, thanks for the heads-up!
That power supply might not be sufficient. If it was only shutting down or struggling during heavy loads, you might have had a power issue.
Not really; if your system booted with the 3060 Ti, the PSU shouldn't be the problem. If you’re having issues, it could just be a dead RTX 3060. Maybe test it on another PC to confirm?

Looks like I need to look for a better PSU then, lol!
