my computerspecs are: coolermaster cm 690 II lite with 4 extra fans
16 GB mushkin DDR3 2000
coolermaster seidon 120XL (2fans)
2x amd 6970 (msi lightning and 6950 with bios mod)

Hi welcome to the forums, but the most important bit of kit you did not mention is the Motherboard! So back to you it goes. AJ.

In my signature is a link to overclocking AMD Bulldozer processors... check it out! Id help but I cant.. AMD is not my thing.

Mobo has nothing to do with the PSU really...the difference between the wattage it pulls vs others is not worth asking even... that said...

Wattage is plenty... quality... not sure on Hyper.
EDIT: Looks like its fine.

Thank you for your quick reply and for your link BTW the PSU is a good one and nice looking to

It looks to me like you have a killer system. Should overclock fairly decent.

Well OP lets try and do some Maths here!

1, FX8350 CPU TDP ABT 125W
2, HD 6950 TDP ABT 200W EACH X 2 = 400W at a HD 6950!
3, Say 40 Watts for rest of your kit etc.
4, TOTAL I WOULD SAY 565 Watts.
But you said you want to Overclock your set up, and do you need to change your PSU?
I would say because i do not know how good is the unit you have there for Stability and line Ripple etc. Maybe other members will say whats right and whats wrong here to help you as well. AJ.

A EDIT FOR ACCURACY!!

That PSU is fine for his setup and overclocking. Those values are a bit off.

THX for your reply AJ the line Ripple on the +12V outputs is relatively high under heavy loads http://www.pcper.com/reviews/Cases-and-Cooling/Hiper-Type-R-Mk-II-880W-Power-Supply-Review

Sorry, that was not the emoticon I wanted, note... wasnt upset. LOL!

 

[Ajay57]

Sorry about the values the boss wanted her Laptop back, but they are not that far off though did a quick Google search for the TDP's. AJ.

 

[asoeone]

LOL @earthdog

 

[asoeone]

@ AJ thank you for your help and time

 

[Ajay57]

See you later and enjoy your OC with your set up and your welcome. AJ.

Correct... but off just enough to question if his PSU was good enough or not. That could have cost someone some serious money... just saying... this isnt hand grenades, horse shoes, and nuclear warfare where close enough is good enough. 'Close enough' could cost someone money they don't have to spend. Accuracy is key here.

 

[Ajay57]

Correct ED fair comment on that. AJ.

Went back and looked at it again and changed it, should be 100% now!
