If I need 1.5 amps for an itx home theater system, will the 120ac/12dc power brick run cooler or last longer if I use the more expensive 10 amp power brick or the least expensive 5 amp power brick. Thanks

Dunno... seems legit to me. Care to enlighten a padawan? – WesleyDavid Mar 9 '10 at 3:31
@Wesley - If I could be so bold as to elaborate for John, the problem is that it really depends on the manufacture of the adapter. Not to mention that this doesn't belong on either site. – MDMarra Mar 9 '10 at 3:35

This is not even a computer related question. A 2 minute talk with an electrical supplier would answer the question far better than a computer related Q&A site could. Besides, it's far too localised. – John Gardeniers Mar 9 '10 at 4:24
Fair enough. It still seems kinda superuser-y to me. – WesleyDavid Mar 9 '10 at 4:29

As long as you're over the 1.5A required it doesn't matter. Look at the efficiency rating of the brick as the best indicator.

Chris is correct, but I've also found that the cheap (read ebay china clones) weigh MUCH less than the original bricks (this is for notebooks) and run MUCH hotter than the more expensive ones so I'm guessing that the guts of the things isn't really up to scratch.

If you want this to last a long time, with continuous, unattended use, I'd go for a locally made (more expensive) unit, but the power rating isn't really the issue here, its the manufacturing quality.
