Hi, after reading reviews I am thinking of buying a XFX 450 for my build ( originally was thinking of CX series but thats bad..) So i heard that the 450 is the same as 550. Can someone tell me if the 450 version is enough for my build, i don't plan on hugely upgrading in the future, heres my build:

CPU: AMD FX-6300 3.5GHz 6-Core Processor (£78.40 @ Amazon UK)
Motherboard: Asus M5A97 R2.0 ATX AM3+ Motherboard (£67.96 @ Amazon UK)
Memory: Corsair Vengeance 8GB (2 x 4GB) DDR3-1600 Memory (£60.99 @ Amazon UK)
Storage: Western Digital Caviar Blue 1TB 3.5" 7200RPM Internal Hard Drive (£39.50 @ Amazon UK)
Video Card:Asus Nvidia GeForce GTX 660 DirectCU II OC 2GB GDDR5 Graphics Card
Case: Corsair 200R ATX Mid Tower Case (£44.99 @ Amazon UK)
Power Supply: XFX ProSeries 450W 80+ Bronze Certified ATX Power Supply (£41.50 @ Amazon UK)
Optical Drive: Lite-On iHAS124-04 DVD/CD Writer (£11.80 @ Amazon UK)

:D THANKS IN ADVANCE :D
p.s I see all answers and I will pick one :)

For a system using a single GeForce GTX 660 (non-Ti) 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.

Total Power Supply Wattage is NOT the crucial factor in power supply selection!!! Sufficient Total Combined Continuous Power/Current Available on the +12V Rail(s) is the most 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...

it's kind of cutting it tight. FX cpu's are hungry, not to mention if you overclock. gtx 660 is a fairly but not too badly power hungry card? if it were me, I'd get 500 or 550w. preferably by XFX.
someone's welcome to prove me wrong though, I find its a tough call.

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.

XFX Pro Series Core Edition 450W v2 (P1-450S-X2B9)
• OEM: Seasonic
• maximum combined +12 Volt continuous current rating of 34 Amps
• one (6+2)-pin PCI Express supplementary power connectors
• Modular Output Cables: No
• Official Intel Haswell Compliance: No
• 80 PLUS BRONZE Efficiency Certification
• 5 Year Limited Warranty

It's definitely more than sufficient to do the job.
