EVGA Nvidia GTX 560 Ti with Coolermaster 450W

[S-Class]

I've currently got a Coolermaster GX450W. Would it be enough for a EVGA Nvidia GTX 560 Ti? Here are the rest of my specs:

i3 2120
Asus P8Z68 V-LX
1x4GB RAM
1 HDD
1 DVD writer
At least 3 USB's at a time

According to extreme outervision it should be OK. http://extreme.outervision.com/PSUEngine

Just want to get some opinions though. Thanks.

If the link doesn't work, they said that it comes to 362 watts, with a minimum PSU wattage of 312.

It probably would be fine.
Only problem is you'll require another PCI-E adapter = the GTX 560ti uses 2 x 6pin

Oh OK, I think it comes with an adapter http://www.amazon.co.uk/gp/product/B004N862GG

I'd personal want a 550W with more amps on the 12V rail than your power supply could provide.

560Ti needs 30amps and yours only has 35A

Using the adapters is never ideal. Although I think the unit could handle the card otherwise, the lack of a second pci-e connector makes the upgrade to another psu warranted.
