Recommended Posts

looking for a 650 or 550w psu.

read some good reviews about those.

also read that the difference is that i version come's with some software.

quiet operation is very important to me.

i wonder why corsair wrote on their site on the i version description- "WITH VERY LOW NOISE' and nothing about it for the x

another question .

is there a difference in fan speeds at every stage between the rm550x and the rm650x?

my planned desktop won't run very heavy stuff .

i prefer go for the 650(my current works with 550, but with less demanding components)

but since i'm looking for silent pc so if the 650 fans run at higher speed then the 550, i may prefer the lower one.

so what will be the different for a user in terms of sonic and thermal operation ?

 

and what is the difference between 650/500x and 650/550x v2?

it's a second version?
