Soooo... Another bad PSU?

[KhalDrago]

System:

Asus Maximus V Z77

CPU: i7-3770K(not overclocked yet)

PSU: OCZ Fatality 3 1000W, Corsair CXM 750W

GPU: MSI Nvidia GTX 780Ti TwinFrozer OC Edition

RAM: G.Skill Ares 16GB 1866 

STORAGE: Samsung EVO SSD, OCZ AGILITY 3 SSD

 

My system apparently eats PSU's... At least thats what I want to see if I can confirm. My original 1000W OCZ PSU seemed to be the cause of constant crash restart issues, so I replaced it with a much more conservative 750W PSU. System has worked great for about a year but it suddenly started freezing in the middle of games, anywhere from 2 to 5 minutes depending on the load. Games I have been playing are Fallout 4, RUST, 7 Days To Die. Crashing first occurred last week after playing around 2 - 3 hours of 7D2D, and now nothing goes more than 5 minutes. 

 

I have verified the HDD integrity and the RAM. No issues found. Temperatures were all monitored and are well within reasonable limits leading up to crashes. 

 

While troubleshooting I found an interesting thing that I want to run by the people. 

 

The MoB has both an 8 pin 12V connector and a 4 pin 12V connector for my CPU power.

 

If I use the 8 pin power, the system freezes hard in game and I have to do a hard boot. Sometimes the system gives me an unable to boot message when trying to restart, but goes away after I try the second boot attempt. 

 

If I use the 4 pin, the games will loose sound first, then I might hear windows components disconnect in the system background, I loose network connection and if I don't exit the game, after about 10 seconds the system will freeze, otherwise it stays on with no sound or network. 

 

I'm guessing it's the PSU even though it's only a little over a year old... but thats around the time my first one started acting poorly also.

 

What does everyone else think?

CX psu's are not meant for high end systems.

Get a UPS, sounds like your psus may be getting dirty power

Even so that's not much load on it to die so quickly

A possibility

Hm that's true indeed, although I would still recommend to @KhalDrago changing it to a good psu from the link in my sig

You are aware that the CX 750 is a half decent psu as it's based upon a different one from all of the rest

Well then... I guess I am done with economy PSUs!  I'll go research a bit more but I am leaning towards the EVGA G2 form the "Best" section of the list that @zyntaxable posted. Thanks for the replies.
