Power Supply Cleaning

[greatman05]

YAY!!!!!!!!!!!!!!!! I GOT THE GRAPHICS CARD I WANTED FOR CHRISTMAS!!!! Now, I just need to clean out the power supply.....I do have a can of air, so from where do I apply the air, back of the PSU or front of the PSU where the fans are located?

Open the case, spray the air up under the power supply first the rear at the fan then blow out the whole inside of the case.
