Is my PSU too Weak?

I've been having issues w/ my machine. I had a nice OCZ PSU that died on me and I didn't have the funds to replace it with an expensive one, so I opted to get a VERY cheap one from Bestbuy: bit.ly/19Svjkc. I think it might be the source of my problems.

When I boot the computer it will load the post screen then show the windows icon and appear to be loading. All of the sudden it flashes green pixels over the windows logo and power cycles, back to the POST screen. It repeats this anywhere from 0-4 times (sometimes I do a hard reset). Every time it ends up working, some days quicker than others.

The rest of my setup:

GPU: GeForce GTX 650 Ti: bit.ly/12FKs24
Motherbaord: Asrock: bit.ly/14fjyRR
CPU: Phenom 9600 Quad Core 2.3ghz: bit.ly/N8egI
RAM: 4GB DDR2 800: bit.ly/16rKX7g
Windows 7 Pro 64 bit

Is my PSU the problem? Is the card just bad? This has happened since the first day I put the card in. It's driving me nuts!

While I couldn't find a review of your exact unit, I did find a review of the 400W version. I included a link to the review in my post. The reviewer clearly stated that the power supply was not really a 400W power supply. No-name power supplies often lie about...

I found the manual here, which might have more technical specifications: bit.ly/1aCexsB.

I understand Dynex isn't a great brand by reputation. I'm pretty sure it's BestBuy's brand they just slap on their label on other manufacturers stuff. The thing is I would be more likely to agree that it's the PSU if you had a reason, aside from the brand name. Is the voltage too low? Is there not enough wattage? What is the actual cause of the problem?

Thanks!

There are generally three levels of power supply quality. There are power supplies that can supply the rated power continuously because their peak output is actually much higher than the number on the label. Then there are power supplies than can supply the power indicated by the label, but if you actually try to draw that much power for any length of time it will overheat. Finally, there are power supplies which will never be able to deliver the output indicated by the level.

I am not sure which group your power supply falls in, but I am fairly sure that is not the first one and it is most likely the last. A good 520W power supply should be able to handle your computer no problem. I provided evidence that your power supply may not actually be a 520W power supply.

Thanks your answer was really helpful, I appreciate it. I may try getting this PSU (seems affordable and comes from a reputable brand). Corsair CX600 http://www.newegg.com/Product/Product.aspx?Item=17-139-028&Tpk=N82E16817139028

Thoughts?

Thanks!

While I agree with purrcatian that you should replace your PSU, your description of the problem sounds like your graphics card is failing. It is most likely still under warranty, so you might want to RMA it just to be sure.

I agree and my plan is to RMA it if it doesn't work perfectly with the new psu.

Thanks,
