What Power Supply Do I Need?!

Hey everyone,

I recently built a brand new PC last week, but I stupidly brought a cheap 700W PSU with very low efficiency.

I need a new PSU, wondering what I need? (I am living in the UK so could you leave that in mind when sending links please)

Intel Sandybridge i7-2600K Unlocked Core i7 Quad-Core Processor (3.40GHz, 8MB Cache, Socket 1155)
ASUS 1155 P8H67-M PRO R3 S/L M-ATX Motherboard
Asus nVIDIA 3D GeForce GTX 560 TI DirectCu II TOP Graphics Card (1GB)
Western Digital 1TB SATA 6GBps Power Saving Internal Hard Drive - Caviar Green
8GB (2x4GB) Corsair Vengeance RAM

Hope you can help!

More about what power supply need
  1. (when not overclocking)around 500w with 32a on 12v rail
    (when overclocking cpu+gpu to around 25percent)
    600-650w with 40A on 12v
  2. Thanks man, the card is factory overclocked to 900MHz, original GeForce 560 Ti is 822MHz i believe. Havent overclocked my CPU atall
  3. You also need a unit with two 6pin PCIe connectors, but those are pretty common in this wattage range.

    XFX Pro 550W Core Edition 80Plus Bronze £55
    Or the 650W version.

    Antec TruePower New TPN-550 80Plus Bronze Modular £60
    Again the 650W version is good as well.
