how much watts does my power supply need?

Im building a pc from scratch, here are the components:
Intel ivybridge core i5
Asus geforce gtx 650 ti
Extreme3 Motherboard (?)
Seagate 500gb hdd

If anybody can recommend a better motherboard under £80 that would be great as an extra.

More about watts power supply
  1. A 550W PSU would do.

    Would depend which CPU you have, as that changes what motherboard you should get. Is Crossfire/SLI and overclocking a concern?
  2. A quality 450W would do. Unless you want to SLI later.
  3. My motherboard is now Gigabyte SKT-1155 Z77-DS3H.


    Could I buy a cit 500w gold 12cm silent atx power supply?

    Fast answers plz :)
  4. Can you link to the PSU you mention?
  5. Based on what I'm seeing, I wouldnt buy it. Doesn't appear to be 80+ Certified and there is no info available on amperage on the rails (which is suspect there are of multiple of with the 12v).
    Its also awfully cheap for a 500W supply.

    This is what I recommend you get.

  6. I cant afford that
  7. The cx500 is about as cheap as you will want to go for a reliable power supply. Its not worth cheaping out and buying a crap PSU which could fail and take your whole system with it. Wait and save for a decent unit.

    This has only one 6-pin. Does the 650ti only require one?
  9. Coolermaster makes junk PSUs. NEVER recommended.
  10. Im not sure about my graphics card
  11. Didnt even think of that TBH.
    A reference 650ti only requires a 6pin connector and so does the ASUS model.
    More arse than class there :P
  12. Can anyone recommend a case and psu bundle that is as cheap as they can make it?
  13. A PSU that is "as cheap as they can make it" is near guaranteed to turn the rest of your rig into an expensive brick. Do not cheap out on the PSU, it is the one component with the potential to kill everything else in the rig.

    Agreed, the case and PSU combos are NEVER a good call.
  15. Do u think that if I wait around two months I will still be able to buy all these components? (My birthday is at the end of this month and I might wait and make changes to the specs etc.)
  16. If in two months you will have the cash to buy proper components, then wait that long.

    What is your budget? I might be able to put together a decent rig based on what you have.
  17. I meant the best value for money psu. Can somebody recommend a good case AND a seperate psu then? Thanks
  18. We can't really do that without a budget in mind.
  19. As close to £60 as possible for a decent case and a good psu. Thanks :)
  20. That will be hard. You will be getting a pretty junky case and a decent PSU. No compromise on the PSU ever.

    The best cheapest PSU you will be looking at is the corsair cx500.
  21. Can you list some cases and psu's please
