I've read that users question before and he has the R2 and I'm pretty sure I have the R1 as I've never seen R2 anywhere I've looked. I've only seen the x51 by itself and I'm told that means I have the R1. So im not sure we have the same motherboard and that the CPUs compatible with his system are compatible with mine.

My X51 R1 motherboard is dead

What brand/replacement motherboard i can use?

Thanks in advance

More likely the cmos battery is bad.

330W power brick is also recommended.
