PSU Fan Question

Hi. I'm looking at two PSUs that are very similar with the exception of the size of the fan.

and

(Corsair TX750)

The first has a 120mm fan, whereas the other has a 140mm fan. I'm just curious what kind of a difference this would make? I ask because taking into consideration s/h, there's a difference of 25 bucks for me between the two.

Thanks for the replies =)

The cheaper one will do just fine

Both products are the same. The 120mm for the first one is mentioned for the Corsair 650TX which is a 650W PSU. IMO the Corsair 650TX should do just fine.

Thanks for the replies, guys.

Actually, the 120mm for the first one is written on the title of the product, so I doubt it's specific for the 650TX.

what are the specs of the machine this is going in ?

Hi Red. The specs are found on this page. See the list recommended by Rage

hey red =P it's okay hahaha

I noticed that too. It seems there's two different editions of the TX750. I guess Canada Computers went for the cheaper one...

Neither of the specs pages list the precise amount of air flow that goes through. So I don't know what to conclude.

The 750TX comes with a 140mm fan. It's a typo on the Canada Computers page.

I knew Moiz would clear that up! :):wave:
