Weak or undercurrent psu for a given system, even if no crashes happen, can cause poor performance for the video card too.

I agree Torrentg,

Weak PSU's can also wreck havoc if your trying to overclock any part of your system., in a nutshell,... if your running SLI or overclocking then the PSU probably isn't the best place to try and save a buck on the build. I've seen guys argue back and forth on this so many times, but in the end, more PSU is better and safer than less.

Heck I'm using a 1000watt PSU with a single GTX280 "overkill" but also more future proof. I'll be able to drop in a couple of 300 series card without having to worrie about it.

Needless to say I don't have any problems with my overclocking or with system performance.

I do not know where you guys saw or came to the idea that I am running 3 Full house Cards on SLI.
Because I’m running 1 Single ASUS Matrix Card, nothing else. I do not have a problem paying more for a bigger PSU. I just thought it would be way to much for what I’m going to need.
The problem was fixed by using my old AOpen 750Watt PSU, so the problem was a faulty PSU and not a underpowered PSU. Because the one I had in was a Thermaltake 750Watt...

You don't even realize that your dual GPU card draws nearly the same power as two GTX285's in SLI. Looking at your comments I doubt you knew the difference between the two.

You also listed the Asus card and another GTX285 in your system specs which say this,..Graphics Card Asus MATRIX GTX285/HTDI/1GD3 GeForce GTX285 16xPCIE 512-bit. Notice the second GTX285 with 512memory? Which would be 3 GPU'S! Do you get it now?

Hmm and you wonder why I thought you had three GPU's? I'll take a guess that your TT PSU could handle the single GTX285 without a problem. Oh that's right, it's defective because it can't handle a dual GPU card right?

IMO your lucky that your old PSU can handle the load but I can pretty much guarantee that if you attempted to overclock your system that old PSU will fold up and die. And it will probably cause you more problems futher down the road. When it does I hope you figure out it's a PSU problem on your own next time.

I doubt there is anything wrong with your TT PSU other than you overloaded it in the first place. The overcurrent protection kicked in to save the PSU, plain and simple. Try it with your single GTX285 card and it will work again. If the TT PSU was defective it would not work at all IMO.

The new PSU has different over-current protection which is the only reason it's still working. Once you exceed it's duty cycle for a good length of time it will probably just quit working on you. If your lucky it won't take the rest of the system with it.

I also have to say this, I answered your question and pointed in you exactly the right direction to fix your problem with my very first post. You never once said thanks for my advice, no Rep, no nothing, you were too busy patting yourself on the back I guess.

Wow dude are you being serious? No need to get aggro.

Graphics Card Asus MATRIX GTX285/HTDI/1GD3 GeForce GTX285 16xPCIE 512-bit
was just copied from a site. A graphics card has Video memory(In my case 1GiG) and Memory Interface(In my case 512-Bit) if you did not know that. Normally the one is refered to as 1024MB and the other one 512Bit. So I just have a full description of my graphics card in my specs. Ill put full description in brackets for you ok?

I do not have a Dual GPU card, maybe you should get your facts right before you try to look smart on a forum. LoLz

This is what a dual GPU looks like: PCI Express - GeForce 9800GX2 - Asus EN9800GX2/G/2DI/1G GeForce 9800GX2 16xPCIE 2x256-bit 1GB DDR3 w/HDTV + 2DVI : Sybaritic - South African Online Computer Store notice the "Dual GPU" in the description and the 1024MB 2x256bit DDR3. Understand?

"If the TT PSU was defective it would not work at all IMO."
That is not true, faulty does not mean broken. We used a voltmeter to check the volts of the PSU when under load when I had my TT in and then again when I had my AOpen in. The volts on the TT's +12V Rail is 11.40V and should be 12.10V like the AOpen. Say I have a faulty graphics card, it does not mean that it does not work at all, it might be fine handling my OS and when I start putting load on it, it does not peform like it should. Still works, just not correct = faulty. LoL

Have a look at this Watt-usage review: Asus ENGTX260 Matrix - Bjorn3D.com
I'm sure a good quality 750Watt PSU is enough for my ONE GTX285 GPU
and the rest of my system. My friend is running this exact system with a GTX260TOP on a Coolder Master 520W PSU and it's working fine.

Then I would have added to your rep after everything is done, but this is what you said in your 1st post: "Are you trying to run two different cards a 1GB x2GPU Matrix and a 512GB single GPU in SLI? I can't help but to think that is the source of your problems. Even if it's not an SLI problem, running three full house GPU's off a 750watt PSU is cutting it close."

Quote from me: "Thanks for all the advise guys, the problem has been solved."
Is that not saying thanks? Do u need a hug aswell?

You thought I was running SLI, just coz you dont understand GPU descriptions. And running ONE GPU vs running 3 has a big difference in Watt-Usage. So the whole time I was tying to make you realize that I only have 1 GPU and you were so busy fighting that you forgot about my problem to start with. Ooooh my rep add add add, I wanne be famous. You acctually need to be friendly and focus on the poster's problem rather than to worry about your rep...
