Is my PSU the Cause of Frequent Driver Crashes?

Since buying my computer just 4 months ago, I've been tortured with very frequent graphics card crashes while playing my favorite games (esp. during Minecraft). I haven't tested all of my components extensively, but all of my component temperatures reside around 40C - 50C at all times, and I've benchmarked my graphics card with good results. My concern is that the problem is my 350W power supply.

Computer specs:
iBuyPower Revolt Chassis
350W Power Supply
Intel Core Fan
CPU: Intel Core i5 3570
RAM: 8GB DDR3 G Skill Ripjaws
GPU: NVIDIA GeForce 650 1GB
Motherboard: ASRock B75M-ITX

Based on these specifications, I was wondering if anybody could help point me in the right direction. Is it likely I should purchase a new power supply? When I purchased this machine I chose some of the parts but did not have the luxury of choosing the power supply for myself. I can't imagine why Walmart's build your own iBuyPower would include a PSU too weak for my components.

Anyways, here's what I was looking at: http://www.newegg.com/Product/Product.aspx?Item=N82E16817139021

750W may be overkill but I have the money to spare for the sake of extra headroom/future upgrades.
