yes, but a bigger one would be better as it will be at max

140Watts [Max Power Draw] for card

none overclocked i5 and system just

i'd still go for at least a 500/600 myself

they said my system will use 211 watt and that means it will be a lot under 450 does it not ? :S

Any other opinions ?

The more power and quality the PSU, the better the PC will run. Get a 650 or something

and another 4gb ram if you can spare an additional £20-30.

450w will be ok, on Andantech they get 287w when gaming, but they tend to use a higher end system.

why on a review i read it said the gtx 660 non ti from msi need 650 but others say 450 :S

The vast majority of people go overkill on graphics card. As a rule, 500W is enough for a single card setup, 750W for SLI/Crossfire. You'll normally get away with 450/650 for single/multi card, but best to be safe for a few pounds extra.

Calculators are based on the theoretical maximum current draw for all the parts in your PC, but virtually nobody maxes out everything at once. If you look at reviews where they actually measure power draw you can get a better idea of real world use: but you have to bear in mind that they don't use as many hard drives as many real-world users, and that your PSU is one of the few parts in a PC that actually gets worse as the capacitors degrade, so you're best off going for one with more power than you need to be sure. And finally, re-using a PSU is one way people save money on upgrades, so it's nice to have a little extra headroom.

A gaming rig will pull around 300W now in most reviews. Add on a bit for your extra hard drives/peripherals (even charging a phone adds 2.5W) and some overhead for capacitor degradation and a graphics card upgrade and you end up at the 450-500W mark most people recommend as a minimum.
