Worrisome? Admir00, you are being very charitable.

peiri, what you have there is a 330 watt PSU - maybe. Read the label. It says "Total average power 330 watts." That 480 watt maximum power rating is meaningless.

The 5570 needs about 45 watts; the 6750, about 85 - 90 watts. I think your current PSU is powerful enough - even at 330 watts, but I wouldn't trust any system of mine to such a junky power supply.

If going that route Washing, I suggest The Corsair 430 (half the price, and just as good as the seasonic).
http://www.newegg.com/Product/Product.aspx?Item=N82E168...
$45 CORSAIR Builder Series CX430 (has a $20 MIR, and is 10% off)

By reading some reviews, most of the buyers experience some RMA, I don't know just saying lol.

The CorsairCX430 is a pretty good PSU, but it is not as good as the Seasonic. It's not even as good as the old CX400, the PSU it replaced.

Compared to the old and now discontinued CX400, the CX430 has:
A shorter warranty - 3 years instead of 5 years
Less 12 volt power - 28 amps instead of 30 amps.
Full rated power at a lower temp - 30 C instead of 50 C.

That's why I ordered a couple of CX400's immediately - like 2 minutes - after I heard they were being discontinued. newegg was out of stock. Had to go to amazon.
