Why don't you open a EVGA Warranty ticket or a EVGA Support ticket and see if your PSU is the problem with your freezes. Your 600 EVGA GD has a 5 year warranty on it.
They might be able to determine if your PSU is capable enough to support the FX 9590 Processor under full load.
NOTE: From what little reviews there are on the EVGA GD PSU, these Models are considered to be Budget PSU (Inexpensive type).
I got this power supply literally like 2 weeks ago, and is still under the Amazon return policy, so that's why returning it and buying another PSU is still an option. Nevertheless, let me see what EVGA has to say.
Found this previous AMD Thread where a User mentions that all FX 9xxx Series NEEDS A MINIMUM OF 54 AMPS on the 12 VOLT RAIL. Your maximum 12 volt is 50 AMPS.What type of power supply unit is recommended for FX-9590?

Sorry. I cannot use English language fully, I cannot write in detail. First of all, I want to share that your PSU is definitely not enough. However, you may have problems even if you purchase a good power supply. Because FX9000 series processors require very high voltages. It also has a very high TDP value. I had to buy a 750W power supply for a FX9000 series processor. And I had to change some settings with BIOS. I turned off Turbo and Cool'n'Quiet features with BIOS for stabilization. I made processor multiplier 44 and gave it 1.48V manual core voltage. And it worked stably.
As I understand it, you can't do an OCCT PSU test. To make this test, try GPU Power Limit setting to -50% with using MSI AfterBurner software. If this test can be done with these settings, you will use your system with a new and good PSU. Your money won't be wasted. Sorry. I don't explain my article. Because I'm having a hard time. I'm trying to write short and clear. Your problem is already very clear so is PSU.
I hope you can solve your problem in a short time. I want to repeat what I wrote from the beginning. Get rid of the FX9000 series system as soon as possible.
Honestly, I didn't even notice your English impediment, but to continue on what you're saying is to try to find stability through the OCCT PSU test and then get a new power supply? Or that if I pass this test this PSU is good enough? Thank you again, and I understand now that it is a my PSU.
You're welcome. Try to find stability through the OCCT PSU test and then get a new power supply. I think that's the right thing. Because reducing the GPU power limit will result in loss of performance. However, it will provide your PSU to load less. I want to give an example. When I used FX9000 series CPU and performed OCCT test only for CPU, the processor was less heated. But when I tested it for OCCT PSU, I saw a significant increase in processor temperatures. That is, 9000 series systems have a northbridge and the processor temperature is affected by GPU temperature. So a good PSU may not solve the problem so I wanted to mention the possibilities that you will have. I'm writing as detailed as I can.
I also agree with Verscotchi about your English. It is very good. I thought you were an American User. You have a good command of the English language which is beneficial to communicate in a English forum like AMD.
Do mind if I ask what is your native language? I am also bilingual whereas I speak English, main language, and Spanish, my parents language. but I only understand Spanish and can barely read or write in that language.
Ok guys, we got some good news. After downclocking to 4.2 ghz and 1.35v I established stability for about 43 min. That was a huge step over the 6-8 seconds of stability of the clocks of (4.4 ghz - 4.7 ghz) After the last freeze, I couldn't really pinpoint the issue for the freeze if it was temperature or voltage, but after rebooting to 4.1 ghz at 1.3375 v I think I have found stability. I did try dropping the gpu to 50% Power Limit, but it still freezed under that setting. So, it seems like the issue was with the clocks and 4.1 ghz and 1.3375 seems to be the sweet spot. Now, am I looking just to upgrade my PSU?
I'm from Turkey. 42 multiplier and 1.35V may not work stably. The voltage may be low. You can solve the problem by experiencing with the BIOS. This is just a guess I will write, 42 multiplier can work stably with 1.42V. So you can only find the correct multiplier and the correct voltage. Although you do not use OCCT, the system crashes at Windows startup probably due to low voltage.
JonnyGURU.com – Home of the PSU GURUs. is a good website to find out about all the new PSU and how good they are. If your PSU is new, can you return it for a refund?
8 years ago when I built my computer, I purchased at Tiger Direct Retail store a Corsair 850 watt PSU. At that time it was one of Corsair Top of the Line PSUs. I am still using it today and working like a charm. Even with a High Quality modern GPU and a FX 8350 Processor with a Asus motherboard that is completely filled with hardware and a USB Hub.
The PSU is probably one of the most important hardware for you to purchase. Try to purchase a PSU of at least 850 watts or more, so that you will have enough power in the future to upgrade your GPU or any other hardware connected to your motherboard.
