PSU - which way up?
Hi,
I've just got hold of a Q-TEC 450w psu. Its the dual fan one and i'm not sure which way it is meant to go up.
Its going in a medium sized tower case, where the psu sits just above the motherboard. If i put it in so all the labels / writing are the correct way up, the fan is pointing towards the top of the case.
If i turn it the other way, the fan would site right above the cpu. I think its an intake fan so would it be drawing the heat straigt from the cpu?

Any ideas?

Thanks
Rob

the hole pattern for the screws should only line up one way, but the dual fan should be down, which draws air from the case and sends it out the psu exaust, even if the fan was on the top side, heat rises, it would still be pulling the hot air from the cpu.

Thanks for the reply.
Although the mounting plate is reversable on my case, when turned upsidedown the power socket fouled the bracket.
This means it only goes in with the dual fan facing upwards. As i said earlier all the writing and layout is normal in this mode, its just the fan is pointing the wrong way!

Strange design i guess, but it seems i can't install it any other way. Thanks for the info anyhow.

Rob

never seen one on top before, usually they are on the bottom of the psu for the reason some psu mount so close to the top of the case, but there are many things i have not seen.
