[QUOTE=slayerking;2634153]No as it will be sucking hot air through the psu, Just get something to lift it up a couple of inches off the base. My case has already killed one psu so I put the wheels on it that came with it so air can get around under it.[/QUOTE]
I will disagree with you here - the case (as shown in his picture) has a large fan in front blowing air over the hard drives; a case fan in both back and top of the case; the psu has a fan opening directly to the right and on the bottom of the case - given the small space below the psu - my guess is that the psu is getting most of its air from this opening.
Turning over the psu and allowing the fan to pull in much more air and assisting in the evacuation of hot air from the graphics cards is still the best option - IMO
Your fact that the same orientation in your case caused the psu to fail only reinforces the need for mrloren to turn the psu over.
(btw - psu’s have been pulling in case air in the top of millions of computers for years - the psu’s being designed for this location and the cases internal hot air)
