  1. What are the rest your system specs? (CPU,Mobo,RAM,etc.)

    That Corsair 430watt is actually only capable of 333 watts on the 12/v rail.The average total system draw with a 6950 1G is about 326 watts.

    We need to know your budget for the PSU and what your system specs are before we can give a good suggestion.The PSU is one of the most important parts of the PC so don't cheap out on it because if it fails it can take other compoents with it,such as your 6950.
  2. does it have to be from corsair? Antec makes reliable, good value psu's. look at their earthwatts series.
  3. are corsair cx psu good?

    The v2 (version 2) are fine!
  5. What are your full system specs?
  6. i5 2500, 4gb ddr3 ram, dvd writter, fanless cabinet, 500gb 7200 3gbps hdd, 6950.
  7. ^ i would be going for a good 550w unit for that build.
  8. Like I said before the PSU is the most critical element in the PC so don't cheap out on it.Also you should think about future upgrades.Perhaps a 6950 crossfire someday.
  9. I like the 'Modular' series and this one will work fine, with some headroom for future additions: http://www.newegg.com/Product/Product.aspx?Item=N82E16817139012

    Another point that I consider is the aging effect of the caps and gradual, but sure, degradation of efficiency.
  10. the op did mention no crossfire, but yeah, for a few extra $$ for a 650-750w model you would be prepared for xfire or a beefier single card in the future.

    Agree! To me, new stuff is like buying a new boat; the moment I step on it, it is two feet too short!
  12. Am not goint to crossfire. Is a 650watt enough for the hd 6950?
  13. You could go with a 500watt and still be ok for a single 6950 but it's always good to get more than you need.Thinking ahead is always good.You could bring the PSU your buying now with you onto another build.Graphics will always get more demanding which will make any current GPU get old very fast.Power is always the same.

    Yes! A good 650 Watts PSU is certainly fine for what you want to do.

    However, 'purple stank' makes some very good points that you need to take into consideration.
  15. are antec earthwats PSUs give better performance at low price as compared to Corsair?

    If so then i will get an antec earthwatt 650watts.

    They are both high quality PSUs. Buy the one that is on sale.
  17. http://www.jonnyguru.com/modules.php?name=NDReviews&op=Story4&reid=110 < earthwatts review see for yourself. If it gets a thumbs up by jonnyguru, then its probably a very good unit. http://www.kitguru.net/components/power-supplies/zardon/antec-earthwatts-ea-750w-green-review/4/ there is also a newer green earthwatts, it looks a bit nicer too....if you like green....and i do!
