Hey everyone, I put together a new PC and noticed a coil whine noise. I’m not sure if it’s coming from the power supply unit or the graphics card, especially since my stock CPU cooler makes a similar sound but isn’t the source. The specs look like a decent build—Ryzen 5, Sapphire Nitro GPU with an RTX 570, 8GB RAM, and an MSI Magician B450M-K II. I heard the PSU is likely the culprit, but it’s hard to tell without testing. If you’re still unsure, replacing the PSU might be a safe bet.
