Is this psu compatible with an EVGA GTX 750 ti?

Is this dynex 400w psu sufficient? I got this gpu one day, and the next day, my computer started to bug out and crash randomly. I'm wondering if it's just the psu not being strong enough.

Here is an example of what happens to my computer http://i.imgur.com/Wf64JXs.jpg

It would start making those strange artifacts, then crash.

Your Dynex PSU is a tier5 PSU:

Tier Five
Avoid IMMEDIATELY. These units are highly unsafe to use. No such protections added, very thin gauge wiring used, false advertising and too much to list. Reference to a higher tiered unit for a better, money saving and a much safer unit. For your safety's sake, please don't order or pick one up for use in your system. These units are a potential fire hazard and could even kill you, let alone your system.

Pick one from Tier1 or 2:

I wouldn't have usually associated artifacts like this with a power problem.
If you draw more than the power supply can handle, it should shut down, although cheap power supplies can fail in less desirable ways.
This is a poor quality power supply. Replacing it is probably the best place to start.

A good 400W supply would be enough with this card.
Some suggestions:
Rosewill Capstone 450
Antec HCG 520
Seasonic G 450

VincentP :

What do you suppose the problem may be? I forgot to mention, that after the screen bugs out, it goes black and then says the nvidia kernel driver has failed and recovered. It does this constantly. And on some other games, the game would freeze at random times, and take several seconds to recover. I was using a GT 740 at first and it was fine, but when I got my GTX 750 ti, it started doing this.

Compatible , yes , should it be replaced yes , to protect your other components.

igibob :

Display artifacts indicate a graphics card issue, but this could be caused by power problems.
Make sure your display drivers are up to date, since this costs nothing.
I think replacing the power supply is the next step, since you would be best to do this anyway with a poor quality supply.
If these fail, it could be a hardware fault in the graphics card.
