power supply problem with Gigabyte GA-7NNXP motherboard

When i first biult the computer with GA-7NNXP with a cheap 400W power, I always had a lots of problem to start up the computer. Then I changed my power to HIRO 400W(They said it's actual watts is 300W). but I still had problem when i ran lots of softwares at the same time or playing 3D-games such as Warcraft3. The computer always restarts automactically. I then sent my power for repair and got another power from my friend. After a few days, the power was overloaded and got burned.

Does anyone know what kind of power do i need for my motherboard?

my cpu is AMD 2800 XP Barton
agp is Chaintech GeForce 4 Ti 4800 SE
Maxtor 120G ata133
Maxtor 120G sata



oh...and is it normal for the computer to beep twice before startup(before the screen where you enter the bios and do the memory test)??

but my friend said the hiro is made for Compact computer....
it's just a little cheaper than the Enermax power.

well i've never heard of hiro and if it's for compact and yours doesn't seem compact with 2 hard drives, i'd get a psu for big comps..

a psu for big comps

what do you mean

as in a lot of componenents therefore drawing a lot of power.
If the problem is a lack of power coming from your power supply, you need more watts.

oh....i know.....
i have tried so many power supply...i already have too many pwoers at home
so i want to know what is the actual watts when my motherboard is at it's full load.
That way i can add more componenents as I like in the future without buying another power supply
