My new motherboard is a Biostar Hi-Fi A85W. I bought it with an AMD A10 5800K 3.8GHz bundle on Newegg. I'm using a 430 watt Thermaltake PSU to power everything. My current build features an AMD Radeon HD 6870, 2 x 4GB DDR3 RAM sticks, 2 hard drives (1 Seagate Barracuda 500GB & Wester Digital 250GB) , and the case is an Azza Toledo 301. The first time I tried to turn it on, everything worked, fans and all. I kept it on for about 5 minutes then turned it off to place everything into my case. When I placed it into the case, plugged everything in, and screwed in all the necessary screws then tried to power it up, nothing would budge. A little red light is on underneath what seems to be my sound card, but that's the only light on. Pressing the power button on the MB doesn't do anything either. I asked around and the general problem seems to be the wattage of my PSU being too low. I'm not sure if that's the main culprit, but any help would be greatly appreciated.
