A good power supply(PS) has two fans and is installed upside down to the picture.
The reason the fan is on the top in the picture it to show you it has two fans.
I run an Antec 550 True power and after I sent a bad one back the new one rocks. I also run an Antec 380 True power with no problems.
Antec has great products/ customer service and getting a bad PS was a fluke.
Also, Thermalright is fast gaining on Antec with a super 500 watt gamers model that comes with all sorts of extras.
Your call. I would research both to see if they meet your needs.
