I own a 3060 OC V2 from Asus (purchased in June) and a 9900KF. These parts consume a lot of energy. My power supply is around two years and a month old. It’s an EVGA Bronze 850W Semi-Modular, which was the top choice I found at the time—honestly, I didn’t know exactly what I needed. I suspect I’m hearing some whine from the PSU and possibly clicking noises. Now I realize this could indicate a failing PSU. My graphics card is showing artifacts under stress, and even viewing dark-themed websites seems problematic. I’m not sure why, but it strongly points to a PSU issue. Is this a likely scenario? Would you think my 550W unit could support this build? I don’t have extra cash to replace the PSU just yet—parts are around $400 (cables and an EVGA T2 850W Platinum), so I’d prefer to save until I can afford it.
Yeah, somewhat. But as long you're not pushing the system to extreme limits like LN2 overclocking, a decent 850W or even 550W power supply works fine. Quick search: a 130W CPU, 200W GPU, 100W rest, total around 430W—those figures are likely pretty optimistic and your parts probably use much less. Just because you think power usage is high doesn’t mean the issue is with the PSU; it’s more likely a cable, monitor, or GPU problem (maybe two monitors at once? That’s common).
It appears the issue might not be the cables, especially since they're not connected together. The system is running at 250W, which aligns with expectations. I've got an AIO with four DIMMs, six case fans, an M.2 slot, a mechanical 4TB drive, and an SSD. It's also useful to know I've already checked temperatures and been troubleshooting for some time.
I understand, a 550W should be sufficient in that scenario, but 850W is definitely acceptable. Most PSU problems usually result in crashes. It seems the issue might be with the GPU. Could you share photos of both monitors to show the problem? Also, check if similar issues appear in screenshots.
I struggle to see it clearly, but I catch small details because my eyes are very sensitive. It feels more like ghosting than actual artifacts most of the time. I was worried about this, as I don’t have any warranty and they won’t replace my card. Buying from Asus was a bad choice.
