Hello,

Which PSU do you think is a better option for my system, for the money?

XFX 650w http://www.newegg.com/Product/Product.aspx?Item=N82E168...
SeaSonic 750w http://www.newegg.com/Product/Product.aspx?Item=N82E168...

My specs are:
i7-3770k
asrock extreme4
evga superclocked 650ti boost
2x4gb ram
standard 2tb hard drive
standard dvd tray

Or is something else better?
Thank you

Personally I would go with the Seasonic 750, However the XFX is manufactured by Seasonic.

Both are overkill for your system, but do provide enough power for adding a 2d 650 Ti BOOST in the future (which would really make your system Rock!).

For a system using a single GeForce GTX 650 Ti BOOST graphics card NVIDIA specifies a minimum of a 450 Watt or greater system power supply that has a maximum combined +12 Volt continuous current rating of 24 Amps or greater and that has at least one 6-pin PCI Express supplementary power connector.

For a system using two GeForce GTX 650 Ti BOOST graphics cards in 2-way SLI mode NVIDIA specifies a minimum of a 600 Watt or greater system power supply that has a maximum combined +12 Volt continuous current rating of 33 Amps or greater and that has at least two 6-pin PCI Express supplementary power connectors.

Total Power Supply Wattage is NOT the crucial factor in power supply selection!!! Total Combined Continuous Power/Current Available on the +12V Rail(s) rated at 45°C - 50°C ambient temperature, is the critical factor.

Overclocking of the CPU and/or GPU(s) may require an additional increase to the maximum combined +12 Volt continuous current ratings, recommended above, to meet the increase in power required for the overclock. The additional amount required will depend on the magnitude of the overclock being attempted.

The XFX Pro Series 650W Modular Edition (Bronze) (P1-650X-XXB9), with its maximum combined +12 Volt continuous current rating of 53 Amps and with four (6+2)-pin PCI Express supplementary power connectors, is way more than sufficient to power your system configuration with a single GeForce GTX 650 Ti BOOST graphics card. It is also way more than sufficient to power your system configuration with two GeForce GTX 650 Ti BOOST graphics cards in 2-way SLI mode.

They're both great PSUs, but for 10$ more, I'd choose the Seasonic 750w.
