Is my psu long lasting and durable

There are 3 versions. The first 750TX was made by CWT and was a very good unit. The 750TX V2 was made by Seasonic and an even better unit. Now there is the 750TX V3 although V3 is not written on it anywhere. It will have model 75-001309 written on the label on the side if it's the V3. The V3 is made by Chicony Power Technology and is so new that no real reviews exist for it yet.

Chicony Power Technology is also HiPro and they make some good units but some of the things I have seen about the V3 make me think it will not be as good as the first two versions of the 750TX. Like using cheap made in China caps and not quality Japanese models. Even if it's not quite as good as the earlier models it will probably be a pretty good unit though. I have read that the real reviews will be out by the end of the month. Those will tell if it's a good model or not.

How can i tell if its v2?

It will have a V2 on the box and on the sticker on the side.

Mine doesnt  

Does it have model 75-001309 on the sticker? Did you just buy it? If so it's probably the new model. That's what newegg has on sale. Click on the picture then the picture of the label. You can see the model number.

Even if it's the new one it will likely be a pretty good unit. It still will be built to Corsair's specifications. I would not worry about it too much. Personally I am waiting on the reviews to actually recommend it though.

Cp 9020042-na

Does the 'Cp' in that item code mean Chicony Power?

CP-9020042-NA is the Corsair Enthusiast Series TX750 V2 that uses Seasonic as its OEM.

The -NA suffix indicates that it is made for the North American market (i.e. meets the regulatory standards for the North American market).

You sure? It doesn't say v2 anywhere tho. Thx

Google on CP-9020042-NA and you'll know.

And is $110 a good price for it or should I get the xfx core 850w for the same price

They're both made by Seasonic.

The XFX ProSeries 850W PSU - 850W Core Edition Full Wired (Bronze) - P1-850S-NLB9 should the one you should get if the price is the same (i.e. better value for the money spent).

^ Yep. The question is do you really need 750-850 watts?

If you're planning on running two GeForce GTX 680 in 2-way SLI or two Radeon HD 7970 GHz Edition in 2-way CrossFire mode and you're also planning on overclocking the CPU and GPUs then definitely get the XFX ProSeries 850W Core Edition PSU.

I have a 7950.but i might get the 7970

Just one? If so you only need a good 550w power supply.
