When I first built my ECS box, I used a cheezy CompUSA $20 PowerSupply. A year later, it failed. I happily replaced it with a $35 'almost-top-of-the-line' 300w power supply. It doesn't post.
The fans spin, hdd spins, cd drawer opens and closes but no video, no bios beeps, nada.
I have seen several other people who have had this problem w/this mobo. The power supply is fine. The specs are clearly within range of satisfactory. I really think the first incarnation of the K7S5A is sketchy with respect to power.
Anyone Else have this prob?
