I purchased a inexpensive PC and decided to upgrade the PSU and the GPU listed above so that I could do some gaming at acceptable FPS.

I ran into an issue were the rig would turns off suddenly then back on for a second then shuts off again while doing some heavy gaming for an hour.

When I tried to power on the rig again it would not work. I then noticed a red light on the PSU and looked it up. The info I retrieved stated that on this model a red light indicates a short.

I then decided I would just build a new pc. I purchased the above parts and assembled my new rig with a clean install of windows, but yesterday while gaming it happened again, red light on the PSU and all.

I thought well I have a bad PSU, but I also noticed that my GPU does show some pixelation on the address bar on Firefox, and while playing videos on YouTube which look like little sparkles, which are not very concentrated but sparse on the right side of the screen and disappear when I drag the window to the left side of the screen.

Pixelation and display issues are common problems when there is something wrong with the power supply. The graphics card is sensitive to PSU issues. Although there is always the possibility of the problem being related strictly to the graphics card, the AXi does have some known issues. Even for such a high end model I've seen a lot of AXi owners with issues similar to yours.

I'd suspect the problem is with the power supply.

Do you have another power supply or another graphics card you can use to swap one or the other of those out to see if the problem persists? If not, I think I'd start by RMA the power supply.

I do have a another PSU, but it does not have a PCI-E 8pins connector, so i would not be able to power the video card, and unfortunately I don't have another video card.

Is it normal for a PSU to red-light when it cant provide power? I looked up my PSU model it (corsair web site) states that a red indicator indicates a short.

I did my homework before I built the rig so much so its color coordinated (blue) and the PSU should provide the needed power unless like you said there is a fault within the unit. I forgot to mention its not a cooling issue as the temps in my pc don't go above 40c.

Seems the red light is an "internal" fault, not external, sfaik. As I mentioned before, it seems to be a fairly common issue with these units. Corsair units in general are crap as far as I'm concerned. Some of our members and even some of the moderation team disagree and claim there are some good corsair units, but all I've seen or experienced with them is a lot of common failures and units that don't even make it to the end of the warranty period.
