My System:
MSI Z87-G45 Mobo; Intel i7-4770k; Thermaltake 650W EVO_Blue 2.0; Corsair Vengeance 8GB DDR3 1600; EVGA GeForce GTX 660Ti; Windows 7 64 bit

When I run anything with much graphics (WOW or most any graphics stressing software) my system shuts off almost immediately with no errors or warning, then restarts a few seconds later with a windows was not shut down properly warning. All of my temps are fine and I've reset everything to default. I called Thermaltake to see what they thought and they thought I had a faulty power supply so they sent me a new one. I just replaced the power supply and its still doing the same thing. They are closed and I will have to call them tomorrow to see what they say now. Please help. This is my first build and this problem is really crapping on my parade.

That PSU is junk. Thermaltake isn't good. It is most likely the problem.

Get a new 500-600w unit from antec, XFX, Corsair, Seasonic.

What are your temps under full load (CPU/GPU)?

I don't think I have even gotten to full load. My CPU temps run around 55-60 while playing Wow and my GPU gets up to about 70 then it shuts off. I've also run Unigine which came with my GPU and it shuts down as soon as the test starts. It started out lasting a little while, but now seems to shut off immediately.

I called Thermaltake and they said it sounded like I got a faulty PSU so I paid a deposit for them to sent me a new one and I am to return the first one for a refund, but it arrived today and it still does the same thing.

I'll call Thermaltake tomorrow and try to return my original and the replacement for a full refund. I've lost over a month dealing with this issue. Not a happy first time builder.

I also have a DVD burner and plan on adding a cooling system in the future maybe liquid. Is 650w enough? What if I added another video card for sli? What watt should I buy to not overkill but give me room to grow.

I don't really have access to do these kinds of tests, but my motherboard does have integrated graphics so I could plug my monitor into it to see if that changes anything. Do I need to remove my video card or can I just plug the monitor into the motherboard video output?

I have also read in a few threads regarding a similar problem that it could possibly be a bad connection meaning that something is not plugged in correctly. I've unplugged all the power cables and replugged them back in and it didn't make a difference. Do I need to remove the video card and/or processor and/or memory to make sure everything is seated properly? I don't think this is my problem, but who knows.

Another solution I've read regarding similar problems has been that i may have "dirty power" meaning that my outlet that I have the system plugged into could be causing the problem. I've had other computers plugged into this outlet and I've tried plugging it into other outlets and it didn't seem to have an effect.

I'm going to try calling Thermaltake again this afternoon when I get home from work. Fingers crossed they will refund my money so I can get a different brand.

If I go ahead and get the bigger PSu to give me the ability to use SLI in the future are there any issues with having too much power. I'm sure it's probably not the most efficient power wise,but will it create any new problems to have the higher capacity PSU?

Thanks for all your help.

Update: I called Thermaltake and all of the tech people and managers... where in a "meeting" and I was told to call back Monday. So I pitched a fit and told the poor lady answering the phone while everyone else was in a "meeting" that I was going to contact Amazon and tell them the problems I am having and give them bad reviews, so she went to pull someone out of the "meeting" and about a minute or two in the line goes dead. I called back and the same lady answered even though this time I selected to speak with someone in the accounting department instead of the service department. Hmmm... She apologized for dropping the call and put me in touch with Andrew. Andrew is also the same person that I spoke too the other two times I've call them to discuss this problem. So I express to him how angry I'm getting with the situation and that I just wanted to get my money back and to send him back the power supplies. He said that he could only replace the unit with a new one, but he promised that this time it would be double checked and certified to work before it leaves the factory... Yea... what the #@!?!!! I asked him if there was any way I could test the power supply myself before taking two more weeks for him to send me a new one. He at this point has never asked me any questions about my system or settings or anything. And he said yea he could send me some multi-meter testing instructions. So an hour or so later I get his email and he attached a jpeg chart of voltages and his email even states to follow the link below to the instructions.... but no link... no instructions... I replied back informing him that he did not include the link, but it's Friday night and I've not heard back. I'm not a happy camper.

So my vcore voltage was running around 0.12 volts yes that low all the time. It would fluctuate between 0.1 & 0.4 The only card I have is my graphics card, so I took it out and I'm now using my integrated graphics. My vcore is now at 1.12 volts which is what I think it is suppose to be. But now I don't have anything to stress the power supply with to see if it shuts off. The only thing on the power supply is my MoBo, 7200 HD & DVD Burner. So is the graphics card causing this issue or is it my power supply? Anyone know how to test a power supply with a multi-meter? I don't want to start sticking probes into plugs not knowing which is what...

On the power supply they sent you if you used a credit card do a charge back saying part is bad and is your second power supply. You have to eat the shipping cost. If you used newegg or micro center and it just over the 30 days call them and speak with a customer service rep. Make sure the next power supply is haswell cirt.

Update: I re installed my graphics card and was looking at the cables and how i had it hooked up. The PCI express cables that came with the power supply have two PCI express 6 pin +2 and one 8 pin on the other end. Previously I plugged the 8 pin into the psu and both 6 pins into the card so I only had one cable from my card to the psu. This time I tried plugging both of the 8 pin to 6 pin cables. At first I thought it solved the problem, but after a few minutes... "blink".. off. I started up Unigine and started running on basic... ran a full benchmark without shutting off. Then I tried the next setting up and a few seconds in and it shut off. My CPU temp was around 75C and my GPU was around 45C. My vcore was 1.112 volt, which was new, because with the one cable hook up my vcore was always less than 1 usually reading 0.12 So... what the frick!!!

So this is the new PSU I'm thinking about: Corsair Professional Series HX 750 Watt ATX/EPS Modular 80 PLUS Gold (HX750) Please let me know if this is a good choice or if anyone has experience with it. I want to have room to go with SLI and a liquid cooling system in the future but don't want to get ridiculous. Is the AX series worth upgrading too? I would like to pull the trigger and buy a new PSU so it can ship out on Monday.

I purchased a Corsair Professional Series HX 750 Watt ATX/EPS Modular 80 PLUS Gold (HX750) it should arrive next Wednesday. Hopefully this will fix the computer issue. Monday I gotta call Thermaltake back to get these back to them and my money back. I have a feeling that I will be selling some Thermaltake stuff on ebay "as-is"

OK, Andrew with Thermaltake sent me the PSU multi-meter testing instructions and the voltages are with-in specification... But this test does not put the PSU under load...so I don't know, It shuts off when the videocard starts working hard. I'm concerned that I have a new Corsair PSU on the way and something else may be the problem? I have the original Thermaltake PSU and the replacement, both are testing within spec and a new PSU on the way. I don't know what to do other than wait until the new PSU arrives on Wednesday. Can something else be the problem? My videocard? This is my first build but it should not be this hard. Everywhere I've looked my symptoms point toward power supply. I'm also concerned that if these PSUs are bad can/could it hurt my other hardware?
