If it has the launch BIOS, the CPU could be pulling more power than it needs, common thing on early BIOSes for this platform, and that might explain the PSU being overwhelmed. Could also be some weird BIOS bug for the board. It is also possible that your CPU is throttling, so while the first thought might be the PSU, it might not be. So testing it with lots of airflow should allow it to push that 450W. The GPU might use 175W, say 50-75 for the board, memory, cooler and fan, 85W for CPU (maybe a touch less, or a touch more), drives use only a little bit, so you're looking at like 300W - 350W so the PSU would be fine. I can't say for sure it's the PSU though, but SFF cases usually don't have great airflow, and that PSU's relatively low temperature rating is odd to me, and your system is likely very close to 400W if you have the CPU OC'ed. If it works fine in those conditions, then likely PSU is culprit. This would allow the PSU fresh air all the time.

The two are related because the power delivery changes, and neither is a "fault".Ĭlick to expand.I would test this by taking the entire PC apart, and assembling it outside of the case. It is commonly heard obnoxiously when the work being done by a GPU is slight, and FPS is high, but the reverse can also be true too, I suppose. because the power being used by the GPU when this happens has changed. The coil whine changing when the FPS drops is natural. It's not really a problem, just something that happens because of the switching frequency of the power delivery, and as such, it's largely unavoidable 100%. So, "coil whine" is induced by the frequency of the power delivered. If your GPU is internally exhausted, it could be that the case inside is too hot, and this causes the PSU to flake out, which then causes the GPU to stumble a bit. I'd says PSU is crap and is causing GPU to throttle as you surmised. Looking at PSU is a good idea, but what's funny about that PSU is that it's 450W rating is only good at 40c, but the marketing material on Corsair's site suggests that it's good to 105c, because of "Premium internal components ensure solid power delivery and long term reliability." and "Zero RPM mode for virtually silent operation, and 105☌ All Japanese capacitors for better reliability.", but I can't understand how a PSU is quality if it says "Engineered to meet maximum power output at a 40☌ temperature rating." I'd be more looking for 65C or 70C myself to call something "quality" (55c is a normal de-rating point), especially in SFF use. The two are related because the power delivery changes, and neither is a "fault".

However, when I pair the GPU in a different setup with a TX750V2 PSU, the coil whine is not being emitted. It's basically like the frame freezes for some ms, then continues on.Īnyone have suggestions for solutions in regards to this? Give the GPU more voltage/undervolt it? Raise/decrease the power limit? I have isolated the coil whine to the GPU, as the noise is 100% coming from there. That is - at the exact point when the game micro stutters, the coil wine stops, then starts up when it's all smooth again. When I play games, I can hear coil whine from my GPU in sync with when it stutters. My finished mini-ITX build works great except for this weird micro stutter going on when I play games.
