What wrong in Intel E6600?

Bro. Your PSU has 2 rails and a total of 20A. Thats a theoretical maximum before shutdown of 240W on the 12V rail. Thats MAX>
But, as you have a poorer quality unit, it not only has an old ATX design standard, it also misses out on undervoltage protections (protects against brown-outs).
The ATX design standard means that the 12V+2 rail is dedicated (via your mobo cpu power cable) to the CPU. Thats a full 1 rail, 10A of the total 2 at 20A used and not available to the motherboard, graphics card, ram etc.
So in actual fact, you're looking (with de-rating) at about 8A or ~100W on the 12V+1 rail before shut down (which is what is happening).
Now, you have a E6600 with a TDP of 65W.
A 550Ti - 116W
And some other gear 50W (hard drives etc)
That's ~230W. Correct, but your PSU can only provide 100W on the 12V rail that the 550Ti is on, and it needs more. The PSU is too weak.

No you are wrong. He have 460 watt which it can support GTX 550 Ti and CPU. Plus i don't think his PSU is dual raid unless op provide a specs or model number for us can research it.

Bottomline Bigfella is right on: the power supply he has is not good quality. Most power supplies on the market presently are poor quality. If you want suggestions on a replacement power supply unit we can point you in the right direction. But it is possible your motherboard or RAM was also damaged by this power supply.
Also, get yourself a quality surge protector.

You have no idea. The PSU has a total of 32A on the 12V rail across 2 rails. 1 is dedicated to the 12V rail for the CPU, that is 22A gone. The other is 20A but can only deliver 10A of those (due to the design).
Derate it and you get what I was saying before.

+12V1@22A, +12V2@20A
V1 is for CPU and V2 is for PCIexpress video card.
That should be good enough. Combine is about 25 Amp.

No it is not. It is bad CPU. you need pick another CPU.

Then why are you got blue screen with this CPU?
That is the CPU problem, not your motherboard nor RAM.
BTW have you use PSU tester?

You are assuming that the processor is the problem without going through thorough troubleshooting steps. It could be the RAM, motherboard, power supply, a hard drive or software giving him problems. The last thing I would suspect is the processor at this point but I would not rule that out either.
Now bigfellla, now you know we have had this argument before. Its true that the 1 rail is dedicated to the CPU. All that means is nothing pulls off that rail but the CPU. But that rail does not hold amps. That is just the limit that one rail can pull.
If the CPU rail is pulling say 10 amps. The second rail would be free to pull up to its max of 20 amps. This is just a single rail power supply that is split into 2 rails. Its not a true dual rail power supply.
Like I said, its true that nothing else pulls off that rail and the rest of the system pulls off the other rail. But it does not hold amps. If your really convinced that the amps are held on that rail, then show me what circuitry has the capability of doing that. It doesnt exist.

But this power supply is pretty much junk and cant pull probably what it claims.

Nope. Intel Celeron is work on his motherboard, as well as RAM. That is why i ask OP to do PSU tester. It can be 12 volt CPU power issue.
If there is 8 pin CPU power on motherboard but if use 4-pin CPU instead of 8-pin, sometime it can be problem and it won't fully access to CPU.
