Hi friends, I recently built a new pc. Specifications are :
AMD a8 6600k black edition 3.9 GHz overclock 4.1-4.2 GHz
Gigabyte GA-G1 sniper a88x motherboard bios version F8
Corsair Vengeance 8 GB ( 2x4 GB) mhz
WD caviar green 1 TB hard drive
Cooler master K281 mid tower cabinet
Sapphire R9 280x 4GB Graphics card
And I have a PSU seasonic m12ii evo 620w fully modular. I have problem to how to put it in the cabinet. For this, my cabinet have a place in bottom to enter the air in the PSU. But if I put the PSU in such a way that the fan comes downword. If I do so, the names and pins gets inverted. So, how I install psu, fan on upper side or fan on bottom side? Does it affects on internal of psu?
(Don't think it is silly question)
THANKS IN ADVANCE

Either way works fine. If fan down, air is drawn from outside (if there is a vent for such) or inside with the psu raised off the deck a small amount. If fan up, the air is drawn from the case, as is normal for the majority of top mounted psu's. Fan down will not usually affect case temps, but fan up will often act as another source of exhaust, especially for free-air style gpus heat.

While it is true that most components operate better at a cooler temp, your psu will function just fine at anything under 55°C or so, and since the case temps rarely ever meet that except in very badly oriented airflow, high end pc's running sli/crossfire with high end gpus pushing @1000w or more, etc.

So, psu orientation is up to you, the owner, but...
