Just because a PSU says it can handle a vid card does not mean it really can. Most PSU's have a single 12v rail that everything goes on. Depending on what you have inside your machine, and the quality of your PSU it could easily be lack of power. If your GPU never gets above 43c you can safely say that it is not overheating. But you can not determine if it is getting enough power.

Usually when the GPU doesn't get enough power, your vid card driver will crash, and this will fire an even in the windows even viewer. Most of the time it will just crash and recover, but not shut down your PC. But it is possible.

So if its not an overheating GPU it has to be one of two other possibilities. The CPU, MB or both are overheating and your computer is shutting down to protect itself. Or. Your PSU can not provide the amount of power your computer requires to run, and is shutting down.

Check the Windows Event Viewer and look at the logs at the time of the shut down. It will tell you if your computer shut it self down to protect itself. It will also tell you if your video card driver crashed and recovered. What it will not tell you however is if your computer did not have enough power and got shut off due to this.
