PSU upside down?

[toolman3]

have a Antec 900 case and would really like to use the corsair 620 PS.Unfortunately the Antec case has the power supply on the bottom of the case and the PS's fan is on the bottom also.So i was wonder if there was any issues with turning it upside down so the large fan on this PS is pointing up. Thanks

Generally it's not a problem but some sleeve bearing fans lose lubrication faster when positioned like this and might then suffer shorter lifespan. I don't know if that fan has a sleeve bearing or not.

The fan used is double ball-bearing, it should be fine.

I do not think there are any sleeve bearing psu's on the market. I know some of the original Seasonic psu's (from the land before time) had sleeve bearings, but those aren't available anymore.

There are many many PSU with sleeve bearing fans. A large percentage of generics are, as well as some past FSP/Sparkle and Ultra 120mm just to name a couple. If the fan label or product specs don't say it's dual ball bearing, it probably isn't.
