or am I better waiting until the Silverstone Strider SST-ST45SF SFX Series - 450 Watt are back in stock??

350w is more than enough - a 200w unit would be plenty.

Approx 80w for the CPU, 30w for the GPU, and no more than 50w for everything else (more likely 30w). 170w max

And why not get a i3-3225, which has HD 4000 graphics? HD 4000 is more than the equal of an AMD 6450.

Easily. In this review with a 6970 the whole system pulls under 80 W. The GPU will add about 25 W, so total ~ 105 W.

You might want to look at a 150 W PSU in the future just to improve efficiency (less wasted power).

@cheesyboy I've had issues in the past with running without a graphics card... when I'm editing photos I seem to get an incredible amount of lag, as soon as I stick in a dedicated card the problem goes away


thanks both of you for the help

No problem.

Although as above that's not the way I'd spend £400 - I'd get this AMD spec instead. Far more powerful (the integrated GPU can play the newest games at decent quality levels, it can definitely do desktop work), has double the system memory, and even includes a sexy case and SSD:

what about an AMD A6-6400K 3.90GHz
http://www.overclockers.co.uk/showproduct.php?prodid=CP-357-AM

its got Integrated HD 8470D Graphics thats got to be better performance than a AMD 6450 doesnt it??

 

[joeyjojo]

For an iGPU based machine AMD is the way to go. As you're not gaming pretty much any Richland CPU will do. The 6400K is probably the best choice!

I've got an APU in my laptop, and oldish one and its definitely better than and HD4000 I've used, I recommend them highly, although with using inbuilt graphics I'd recommend the fastest RAM you can afford, somewhere around 2333mhz if you can find some, and your chosen Mobo will support it - I know this is for Haswells iGPU, but it should follow through for AMD as well - http://www.anandtech.com/show/7364/memory-scaling-on-haswell/5
