PSU Help Please!

Need help quickly! About to purchase the intel i7 2600k 3.4ghz cpu, and pair it up with a 560ti graphics card....problem is, I don't think my psu is good enough for this new set up.

This however is my power supply : http://www.amazon.co.uk/Octigen-AT [...] B001KTJVKU

I need suggestions and help in this area, Would it be able to function well? or should I bump up the PSU?

What's your thoughts on this PSU's?

More about please
  1. link not working correctly
  2. Use a PSU calculator like this: http://www.thermaltake.outervision.com/ to determine the wattage necessary for the entire system. The 560Ti will draw a max of 16.42A at peak usage, so be sure the +12V rail(s) can provide that. Then purchase a brand name PSU. Your links are broken, so I don't know what brands you were looking at.
  3. As Scout says the links are bad, but some general guidelines: buy quality PSUs from the likes of Antec, Corsair, Seasonic, PCP&C, OCZ, XFX, Enermax, inter alia, with enough wattage to serve your needs. A 650W (or more) PSU with 80 + rating is what I'd look for.
