Will this power supply be enough?

So I want to build a gaming PC and I got a list of parts and found the cheapest price for each part around the internet and it came to about £450. I've gone on ebay and found an identical computer, prebuilt, with a better case but doesn't come with a graphics card, after factoring buying the graphics card it's still £30 less. I would go for this but the problem is that the PSU used in the ebay build is probably rubbish and i'm not sure if it will be able to cope me adding a 7870. Can someone with a bit more experience give me guidance on whether to go for the ebay one and take the risk that the power supply wont be enough or just stick with buying each part.

Here's ebay link: http://www.ebay.co.uk/itm/AMD-FX-6300-Six-Core-Fast-Office-Home-Multimedia-Pc-Computer-1Tb-8Gb-ZT3-/370948980431?pt=UK_Computing_DesktopPCs&hash=item565e483ecf

Here's the graphics card i would add (It's £133 once it comes back in stock): http://www.amazon.co.uk/gp/product/B00A1572TQ/

And if it helps here is the list of items i would buy if i bought all the items separately ( as well as the graphics card above) http://www.ebuyer.com/lists/list/287927
