Hey, Tom's.
I've bought this XFX RX 560 last week and I feel there's something wicked going on with her. It's GPU clock remains at 200-300 MHz if the PC is completely idle, but at the slightest mouse cursor movement, it spikes up to 600-900 MHz, and the same thing also happens when some simple pop-up comes out in the screen.
It's memory clock is also acting really weird, as it'd stay perfectly stationary at 1500 MHz, even if you're just staring at the desktop with nothing else running in the background. It's also noteworthy that when you reduce the memory clock via Afterburner to 1480 MHz, for instance (20 MHz less), the card will then run idle at 300 MHz in memory clock, rising up until 1480 only when running a game.
Another thing I noticed is that its fan would only spin during the BIOS screen, and never again once the OS has been loaded. The only thing I found helpful in this case is using MSI Afterburner to set a fan curve to force it to spin, since not even that Crimson driver's Wattman is making it.
The saddest thing until now, though, is the sudden shutdowns it's giving me, always when I'm playing but not necessarily everytime I play some game. It's the kind of shutdown you'd expect of an overheated CPU or GPU, freezing the screen while displaying one solid color and looping the last second's sounds, but I'm always monitoring its temperatures and I've never seen it running at more than 55ºC and the same goes for my CPU.
As for the question, I've checked XFX's recomendation on a PSU to power this video card and it was an XFX 450w (can't recall its name). I searched about its 12V output and it shows something like 34A. Regarding my PSU, an OCZ 500W, its 12V output comes in two outputs of 18A each, what sums up to 432W, but since this video card only has one 6-pin input, my PSU can only sustain 216W for it. So what do you guys think? Can a faulty PSU cause all those symptoms I listed above or is the problem with the video card itself?
