I bought corsair 650tx from the newegg...

http://www.newegg.com/Product/Product.aspx?Item=N82E16817139020

It was on promo with rebate... so i thought it would be reliable product at reasonable price...

But when I put them on to my new computer, it turned on led on motherboard.

However, when i press start button it didn't work with odd smell(maybe it's normal for new one i'm not sure)..

so i unplugged PSU immediately.

After i checked every other lines are good to go and tried again, this time it made pop(loud) sound.

After that i decided not to try again... luckily my parts seems not damaged at all.

So, I put my old PSU which is 250w and everything works perfectly fine..

Now, i'm using this computer with 250w with no GPU (radeon 7850) on it.

After this happening, i decided to refund this one and go to offline store (fry's) to buy new one.

I'm thinking about this one from fry's

http://www.newegg.com/Product/Product.aspx?Item=N82E16817371035

it's only 500w, but i think it would be plenty for 7850 and phenom II x4 (no oc, Sli, Cross).

Questions:

1.Antec 500w seems double rail unlike to corsair 650tx single rail one, what's different between them? is it bad choice??

2.What should i look carefully to buy power supply?? Is there any compatibility??

3.Also, do you guys think that my corsair 650tx was DOA product?? or it's just compatibility problem?
