If your case has a bottom intake for the PSU and has enough room to get air for it, then put it with the fan facing down.

define r4. so i think i will mount it fan down

The Define R4 has a bottom intake and a very nice dust filter so definitely point the fan down.

Kinda depends on case and whether or not you will have adequate airflow (if bottom mount).

Just make sure there's enough room underneath for airflow and you'll be fine  (Best to put it on a solid surface and not anything like carpet)

make sure you have adequate space below for air. This could be a problem if it were sitting on carpet. Otherwise facing down is the way to go.

Doesn't matter which way it's oriented. I personally have the fan upwards, because I think it looks better.

i just hate looking at rating stickers on the PSU when mounted fan-down.

fan-up usually looks more aesthetically more pleasing that brash stickers

telling you rating data.

I don't recommend running an SLI setup off of only a 650 watt psu. For that you need >750 watts.

[The_Strict_Nein]

Putting it fanside down tends to put the 24-pin closer to the tray which makes it look nicer and easier to cable route. May not be the case with your PSU but I'm not in a position to check right now

every wattage calculator and people ive talked to say thats fine, people just generally over estimate the wattage needed to run a computer

[Heisenbleurgh]

I had it face up for aesthetic reasons. My RM psu's fans don't even spin so it doesn't really matter but ended up turning it around when I closed up and finished my cable management in case I ever throw in a second one and need that airflow.

I read nvidia recommends 850W as a minimum for SLI 780s. The 2 cards alone can use up to 550W:

http://extreme.outervision.com/PSUEngine i used this thing and it says 650 is more than enough

[airdeano]

then lets hope it is enough.
