So I have a question, if I buy a cls DD, I don’t pay any extra for the boost kit,the power supply is included!! so why when you pay another 150 for the boost kit, is the basic power supply not supplied as well ?
because the CSL DD doesn't come with any power supply and you decide which one you want. it's not like the small PSU is included in the CSL DD.
Look at from the point of view that you get a €20 discount for not having an extra psu when you purchase a boost kit...
or just pay an extra €20 for a spare 90w psu.
Don't think this is correct. There are only two ways to buy the CSL DD - either with the small power supply for a certain price or with the larger power supply for a different price. There is no third option to buy the base with no power supply at a cheaper price than either of these options.
But really, if you have the boost kit and it goes out. Do you really think anybody would "go back" the 90 psu as their permanent solution? Or would they just purchase another 180 psu. Just get the 180 psu and life will be good. It is amazing coming from a CSL Elite.
Look at the back of your CSL elite PSU, you already owned the boost kit :D
Not wired correctly though...
