Question about Haswell Combatible PSU

[Arbiter_Arbiter]

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!

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

That is a poor quality PSU.

Something along the lines of a Seasonic when they go on sale?

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.

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?

 

[Dark Lord of Tech]

I would go to 850 for 2 780's.

 

[Arbiter_Arbiter]

Thank you both again for your responses. I will be buying a new PSU along with my new CPU+MB.

Great choice , enjoy your new components.

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.
