Is my PSU failing?

Greetings,

First, thank you for taking a look and providing any input towards my problem.

About a week ago my laptop began shutting down automatically while playing games. It would reboot and come to the "Windows has experienced an unexpected shutdown.. etc." Rig is as follows:

Force/MSI 1761
- Intel® Core™ i7-2760QM, 2.4GHz
- nVidia GeForce GTX 580M 2,048MB
- 16GB DDR3 1333MHz Dual Channel Memory
- 120GB OCZ Vertex 3 MAX IOPS Sandforce Solid State Drive
- Delta ADP-180HB B 19V --- 9.5A power supply
- Approximately 2 years old

My first thought was that my GPU was overheating. I've been running ArmA 3 pretty heavy recently so I thought maybe I was pushing my rig too hard. Tuned down the graphics and same shutdown occurred. GPU-Z logs my highest temp reached prior to a shutdown at 77°C (as logged after the issue began). I've cleaned out my fan and heatsink fins. I keep my laptop on a hard surface with plenty of ventilation. I do not overclock and my drivers are up to date. I haven't reapplied thermal paste to the GPU, yet. If something already caused my GPU to burn out shouldn't I be seeing other errors?

While I was doing my own research the exact same shutdown occurred while only having my browser open. No graphics, no heavy CPU usage... just browsing the web. This raised my eyebrow and I've started looking into other options. After checking the System Event Viewer, I've had 10 criticals in the past week(most caused by me troubleshooting understandably):

Event ID 41 - Kernel Power. "The system has rebooted without cleanly shutting down first. This error could be caused if the system stopped responding, crashed, or lost power unexpectedly."

As I understand it this event is what logs when the system unexpectedly shuts down, be it freeze, power loss, etc and brings us to the Windows error/startup selection screen, right? The lost power caught my eye and I started thinking maybe my adapter was going on the fritz, but shouldn't my installed and fully charged battery kick in and provide power? Is there another component that could be failing?

I'm at a loss for how to proceed. I've ordered a new power supply with the same specs, but while I wait for that to come in is there anything else I can check out? I jumped at the PSU because it seemed like a fairly cheap direction to continue troubleshooting.

Again, thank you for your time and advice.
