New Build -- possible PSU issue

Hello!

I recently put together a new build; consisting of an AMD FX-8320 Processor, AMD Radeon R9 280 GPU, AMD ASUS M5A97 Motherboard, and a Corsair CX600 PSU. The RAM and other parts aren't worth mentioning, as they're all compatible.

However, when I booted up the new build -- I began having issues with the display signal. Several seconds after rebooting, I would see the display -- but then it would cut off with the HDMI/DVI on-monitor signal error. Each time I rebooted, I received the same error...working display but several seconds later it would give me the signal error. The problem seems obvious, the PSU is insufficient and is cutting the GPU off to save energy/prevent damage.

But I'm a little oblivious, so is this what is happening? Is the PSU too weak for this setup? So I don't waste money on a new PSU. Something worth noting is that I tried another GPU with a much lower power requirement, and I didn't experience this same issue...but I'd get a blue screen/stop screen without any specific stop error. Which has left me confused. Maybe the PSU still cannot fully power the system, and the GPU leaves me with enough power to reach the error screen?

I've tested this PSU and it works with a prior build, as does the GPU. The only thing that's untested on the older build would be the CPU.

Any feedback would be very welcome.

Thank you!

Thank you for the reply. You may be right. There are two of four modules that are in my build that aren't listed in the compatibility list, but the other two modules are listed as compatible. I tried using only one stick and ran into the same issue, but it may have been one of the incompatible sticks. Too exasperated at the time to give it more testing, so I'll definitely give this a look soon.

In the compatibility list: http://www.newegg.com/Product/Product.aspx?Item=N82E16820231314
Not in the compatibility list: http://www.newegg.com/Product/Product.aspx?Item=N82E16820231277
 
I have purchased RAM in the past (always in sets of 2 or 4 dual-channel RAM), and one of the two sticks were bad.

I have "donated" a lot of RAM to friends/charities because I would rather have the peace of mind knowing that all RAM installed is exactly the same. I would put one stick of the compatible RAM in and test it. If that works, put the second stick of compatible RAM in and test. You may need to check the settings in the BIOS to make sure it is set right for the RAM.

While some people have success in mixing RAM - I have had many headaches....and so I just don't do it.

Hm. I've tried every module one at a time, and checked to see if the motherboard read the RAM in the BIOS each time I swapped out the modules (which it successfully did on each module) to eliminate the possibility of a bad RAM slot. The same BSOD every time, regardless of RAM used. All of the hardware I have has been tested to work in another build, except for the CPU and the Motherboard. The display issue I was having is due to an insufficient PSU, as it never triggers when I downgrade to a slower GPU. And I have a screenshot of the BSOD (a very blurry shot due to the camera focus because the error lasts less than a second before looping into a restart) but anyway, the shot can be seen here: http://36.media.tumblr.com/03be07bdce9c1a0ff0a04d50521dc79e/tumblr_ngej3fKp471s95n52o1_1280.jpg

Is there any way to isolate a CPU or...a motherboard to diagnose an issue? Considering all of the other components work with a different CPU/mobo, that these two are the culprits. And there are no compatibility issues to speak of, with the RAM supposedly being a non-issue.

Thank you for your help! I found the solve for the BSOD issue. Because I'm a dorkasaurus that has never reused a hard drive before for a new build, I didn't know there would be driver conflicts causing BSODs. I reformatted and installed Windows over the drive, and that fixed the problem entirely. I still have an issue with the GPU shutting off, but that's a PSU problem. A bad calculation on my part thinking a 600w from the CX series could power everything. The replacement PSU is already being shipped; a Corsair HX 750. If this does or doesn't solve the display issue, I'll update for anyone with similar problems that happen along this thread.

Thanks again!
