Is Corsair VS450 450 Watt PSU good enough for my system?

I am getting a new system built and I have ordered and received all the components. This is the configuration:

1)AMD FX 8350
2)ASUS M5A97 R2.0 motherboard
3)Sapphire AMD/ATI Radeon HD 6670 1 GB DDR3 Graphics Card
4)Corsair Vengeance DDR3 8 GB (2 x 4 GB) PC RAM
5)WD Caviar Blue 500 GB Desktop Internal Hard Drive
6)Kingston SSD SV300S37A/60G
7)HP DVD1035 RW (from my old system)
8)Cooler Master Chassis Cabinet-Mid Tower-Elite 431 Plus-RC-431P-SATA X-Dock Case - has one fan, I might add 2 more.
9)Will sometimes connect an External hard disk and a webcam.
10)Corsair VS450 450 Watt PSU

Now, I'm being told that the PSU I've bought will not be enough for this configuration. Is this true? If yes, which which PSU will be ideal?
I'm not a power user who will add extra graphics cards in the future.

Many thanks in advance.

The VS 450 should be sufficient.
If you haven't already bought it, I'd recommend the Seasonic S12ii 430w, Antec VP450 or the Corsair CX 430V2 over the VS450.

Also, if this is a gaming rig, you should get a much better gpu instead of cpu.

That CPU would max TDP at 125W
GPU max TDP 92W

You should be fine

That PSU will be fine. You could run a HD7770 or GTX650Ti on it with no trouble at all too.

Thank you all for the quick answers. Much appreciate.
Bartholomew, I have already bought all of these. I'm not a hardcore gamer. Will mostly use my PC for using multiple programs at a time - multiple browser windows, Excel, Winamp, Adobe reader etc. and occassionally a light game like Cricket, Soccer etc. and watching videos and HD movies, so I don't think I need a high end graphics card.

Am I absolutely safe with the above PSU, or just marginally safe? If it is well worth it, then I can try to return this PSU to the seller and buy a new one.

You are absolutely safe. You'd have to add drives and fans to even hit 300W.

For a system using a single Radeon HD 6670 graphics card AMD specifies a minimum of a 400 Watt or greater system power supply. The power supply should also have a maximum combined +12 Volt continuous current rating of 20 Amps or greater.

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) rated at 45°C - 50°C ambient temperature, is the most critical factor.

Overclocking of the CPU and/or GPU(s) will 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 Corsair VS450 (SKU# 75-001835 / CP-9020049), with its maximum combined +12 Volt continuous current rating of 34 Amps and with one (6+2)-pin PCI Express supplementary power connectors, is way more than sufficient to power your system configuration with a single Radeon HD 6670 graphics card.

Whoever told you that it's not enough, they don't know what they're talking about.

You need to begin your own thread instead of trying to hijack this [solved] one.
