My Sapphire Radeon 280x Dual-X is doing something terribly wrong.
It is absolutely okay when you are not doing something GPU demanding but when you do it can randomly shut down for some unknown reason.It should not be overheating,because the temperature is about 68 degrees when it happens. Then I think that it is undervolted from the box and this may cause trouble so I downloaded Afterburner and set maximum power percentage +20% and altered GPU cooling fans speeds, so it wont heat real hard. That made the problem less frequent but it still happens.
What can be the problems of it and what tools I can use to provide more info?
Thanks in advance!

750 Watt Power Supply is required.
1x75 Watt 6-pin PCI Express power connector is required.
1x150 Watt 8-pin PCI Express power connector is required.

Maybe bumping up the +20% power on the MSI afterburner program is to much for you PSU to handle. The minimum recommended power is 750W for that card, if you have other peripherals this draws power as well that could exacerbate the problem, I would try backing it down from +20% a bit. Maybe just running at stock and seeing if it is stable there. If it is not stable running at stock it is probably the PSU or the Graphics Card itself. Also check and make sure all drivers are up to date. My best guess is you are drawing to much power from the PSU and need to back down MSI afterburner from +20% usage to a lower setting.

The GPU-Z log attached is recorded on stock settings. It happens on the stock setting and happens a bit less on the additional power settings and gpu cooler % as in the graph.
Maybe I can try to make power limit negative instead of increasing it and see what happens.
