Antec question needs answer please

Flight · 15 Jun 2009 at 10:34

I've been using Antec 900 cases for a while.

With the PSU in the bottom of the case do they go 'upside down' so that the fan is facing up on them.

I know this seems obviously to be the case, but after looking at dozens of pictures of them all the PSUs in them seem to be the normal 'right way up' with writing not upside down and fans seemingly facing down.

Thanks and apologies for what seems to me to be a very basic question.

There should be a gap below the PSU for air to come in, I'm sure the 900 is the same as my P182 in that respect.

Yes there is mate.

Are you saying it doesn't matter which way up it goes (there are gaps top and bottom, although the bottom gap is much smaller) as long as air can get in and the back is clear ? (Obviously the 900 has a separate compartment for the PSU, totoally separated from the main MB section of the case.)

Hmm.. I've got my PSU mounted upside down in my 900 2, never actually thought about it before, the gap below is little more than what's provided from the rubber feet for vibration, I wouldn't have thought that would be enough airflow?

I can't think of any disadvantages of mounting it upside down, other than more dust in the PSU, but a blast of compressed air every now again should sort that out.

Same sort of things I am thinking and what I've done in the past (upside down). Also heat rises, not sure if that would work against the fan.

Also, the opening in the bottom is shaped exatly the same as the fan opening on the PSU, not going all the way to what would be corners of a square.

Only thought about this when I put two PCs together and put the PSUs different ways up in the pair of them. Looked around for advice and couldn't find any. Looked up dozens of images and in all of them the PSUs seem the 'right way up'.

Anyone able to add anything else or offer an authoritative view on it ?

My PSU is upside down in my 300. Works fine

Mine is upside down in my antec 300 too.

My Corsair HX 1000W is upside down in my Antec 1200.
All fine.

Flight · 15 Jun 2009 at 13:24

Yeah I've always put them upside down in the Antec cases.

I need to know if I should take out the one that is the right way up and put it upside down

Any takers ?

My Corsair TX750w is fitted with the fan facing down in my Antec 300 case and I've had no problems.

Having this particular PSU with the fan facing down also helps with cable management (in the 300 case anyway).

What PSU do you have btw?

Both 900's have Seasonic M12D 750's in them.

One facing up and one facing down

i think it really depends on what side the cables come out of, with the fan facing up into case, some have the cables on the motherboard side, others have it on the sidepanel side.

for me the OCZ PSU has the cables on the sidepanel side, with fan facing up.

so i put mine in fan facing down, to allow better cable management, heres a pic,

as you can see, the ay i have it is the so called 'correct' way up, with fan facing down into case, but again its up to you, there is no right and wrong here
