I got a complete freeze playing GTA V that makes me manually reset the machine each time it happens.
No others troubles.
So I started inspetting hardware, imo I can surely avoid temperature problems (35°C idle cpu - 50-53 on load; 30°C idle gpu - 45-50 on load).
At this point I tought it could be a power supply trobule and I verified cable connections. I completely forgot to plug the 4pin 12v atx power supply, maybe because I was sure the 8pin would have been sufficient. I had to buy a molex to 4pin adapter because of my psu.
After installing this adapter I experienced a visible improvement: before this i cannot play for more than 10 minutes, after this i reached almost 2 hours but problem is still here.

I found an useful link about power cables and connectors (click me) and I started calculate.

In my opinion, this cpu needs a huge psu in order to satisfy its 220w tdp and other components, at least 1000w psu. My actual psu is a 750w corsair.

atx 24 pin - 79.2w (+3.3V) + 150w (+5v) + 144w (+12v)
atx 4 pin EPS 12v - 192w
atx 8 pin EPS 12v - 336w
8 pin pci express 150w
---------------------------------------------------------
total - 1051.2w (hypotetical full load)

my configuration is:
Asus Crosshair V Formula-Z
AMD FX 9590
8 GB DDR3 RAM
GTX 970 4GB
Corsair cx750w (it provides 62 Amps on 12v rail)
2 ssd
cpu cooler (zalman CNPS7x led 92mm fan)
chassis cooler (120mm fan)
usb g11 keyboard and mx mouse
DVD+R external unit (usually unplugged)

It would be nice to try a 1000w psu before spending money only on a hypotesys... so what do you think?

Hi omega86 :)

My take on the CVFZ and FX-9590 and from experience is that you do indeed need an efficient PSU.
You need at min an 850W gold certified unit and 1000W gold certified if you intend any expansion or to achieve a decent 5.2GHz OC. The 4pin MB connection is also an important requirement to assist the CPU when demand is high.
Another important requirement is a decent cooler and Air Cooling will not suffice for any more than stock frequency under load and it will still struggle. Your Zalman CNPS7x is inadequate as the FX-9590 gets hot fast when OCing and so liquid cooling of at least Corsair H110 or equivalent is a definite requirement.

A decent airflow within your Tower case is important and a single 120mm fan is also...

Anything you do to try and get a 9590 working is going to be a hypothesis; it's a notorious CPU and sometimes people are *never* able to get it running well. In that case, you have to be prepared to run it like it's an 8350.

But assuming you're determined to try to get this CPU running, first thing to try, given that you *are* experiencing freezing and not having temperature issues, is a better quality PSU. Not necessarily a 1000W PSU, just a significantly better quality one. The old Corsair CXs weren't the worst PSUs in the world, but they were quite mediocre and inappropriate for a CPU like this (presuming you have the old one with the green letters on the label rather than the newer, better one that has 62.5A in the specs).

If you're still having problems there then it's back to the drawing board. But a quality PSU is the next thing I'd try, something like a SeaSonic or an EVGA G2/G3.

You have the best MB for the FX-9590 however Bios tweaks are required for LLC and current capability to prevent voltage droop. I have successfully built a number of these combo's and I must say the FX-9590 whilst being a very capable CPU, it is a beast of a processor to attain and maintain stability.
I can help with any aspects regarding Bios Tweaks should you wish to OC.

As many will probably suggest, sell your MB and CPU and go for Ryzen 7 on the AM4 platform.

That board supports 140W CPU's. https://www.asus.com/us/Motherboards/CROSSHAIR_V_FORMULAZ/specifications/

It states:
FX-9370(FD9370FHW8KHK, 4.4GHz, 8C, L3:8M, 220W,rev.C0,AM3+) ALL 1403GO Due to the high TDP, please be noted there are limitations while using this CPU(i.e. special thermal required..)
FX-9590(FD9590FHW8KHK, 4.7GHz, 8C, L3:8M, 220W,rev.C0,AM3+) ALL 1403GO Due to the high TDP, please be noted there are limitations while using this CPU(i.e. special thermal required..)

What have you done that is special?

Personally i wouldn't waste time, it'll never be 100% stable.

However you could try massive heat sinks on the VRM's, airflow for the VRM's specifically.

And I'm 99% certain it'll be a CPU and not a GPU issue.

That cooler has absolutely no chance to cool that 220 watt processor. If you wish to try to fix it that is your first problem, the next is the low quality power supply AMD recomends a 1000 Watt for that chip.
I would also undervolt it for that board.

Thank you every one for answers.
I'm actually waiting 4 a present from my friend: it will give me the seidon 240v liquid cooler. Atm i'm keeping my eye on temps but I can assure you even on load it won't reach damage levels: I ran another bench yesterday... at least 40 minutes with 8cores at 100%, temp at 54°C.
Then I launched a gpuz bench too but pc didn't freezed.
@DSzymborski: you're right! my psu has green letters on its side. I think fastest (and cheaper) way is trying to underclock / undervolt the cpu. Is it possible to do this working only on the multiplier?

@MeanMachine41: thank you buddy :) I remember I read 220w tdp when I purchased the mobo, but yesterday I controlled the mobo box and it's written 140w support :\ Do you think a coolermaster seidon 240v is ok for cpu cooling? my friend can give it to me for free

Thanks to other guys replied, too! I've made many mistakes assemblying this machine, this is all experience for next time.

About underclocking / undervolting? Can you help me? I mount a 1600mhz ddr3 ram so I think I couldn't modify too much the fsb clock

you've not made many mistakes, AMD et. al. made mistakes releasing that, and releasing it on an AM3+ board, and declaring compatibility where it is dubious at best. You could have researched more, but when someone says it's compatible then you should be able to believe that, and the issues might have taken a while to become public.

Hard to argue about a freebie so give the coolermaster seidon 240v a try however, ivé never tried one and the radiator is of slim design (27mm) has plastic tubing and questionable performance.
