Question about Haswell Combatible PSU

I currently have a old Cooler Master UCP 900W PSU (http://www.newegg.com/Product/Product.aspx?Item=N82E16817171033).

I am looking into getting a 4670k CPU and a new MB but I realize that my PSU is not on Cooler Master's Haswell compatible list: http://coolermaster-usa.com/press_release/haswell/haswell.html

Will I run into issues becuase of that? That latter link describes a method of connecting a simple case fan to the PSU directly in order to take care of possible shut down issues.

Any help would be awesome and thank you in advance!

  1. I would upgrade to a better more reliable Haswell compatible supply.

    That is a poor quality PSU.
  2. Something along the lines of a Seasonic when they go on sale?
  3. Yes that was a simple temporary solution made up by CM, which I personally wont believe. So as Blackbird said get a decent HASWELL compatible PSU for your own good. BTW the sleep states are automatically disabled in most Mb's though. But still get a decent PSU like this one :

    Yes you could go with Seasonic top of the lone PSU maker. My linked one also made by Seasonic, and its a solid one.

  5. One last question and I must thank you both for your time.

    650/750 W would be adequate for SLI GTX 780s along with 4670k?
  6. I would go to 850 for 2 780's.
  7. Thank you both again for your responses. I will be buying a new PSU along with my new CPU+MB.
  8. Great choice , enjoy your new components.
  9. A single GTX 780 will require 42 Ampere on +12V rail of a 550/600W PSU, the card only require 250-270W (reference and non-reference) of power, so in SLI the cards will need approx. 540W, so 750/800W PSU will do. But if you get a bigger PSU it will be better for you, it wont cost you a penny more to operate.
