what other info would u like? I got a 300W PS. I have an 8x DVD burner, a 16X Plextor burner, a 40 Gig Maxtor 7200rpm HD, a generic ethernet card, a volcano 7 over the cpu, a back case fan and a blower in a pci slot.
Usually, even with all that stuff, a decent 300 watt power supply would suffice. I say decent because a lot of generic cases have crapola power supplies made by L&C technologies and other fly-by-night companies. Frankly, these power supplies are dangerous. I've had several of them literally blow up. Inside, capacitors exploded. On one occasion almost causing a fire.
One other thing could be over aggressive RAM timings. You could try backing them down a bit. But more than likely it's your power supply. I have my K7T266 Pro 2 with the most aggressive settings and it works like a champ.
I can't think of a good signature so I'll use this one.
