I just replaced my mono then when I started my pc.
I heard electrical buzzing from my psu....

Before that a screw fell inside the psu so I have to shake it off...
Did that shaking cause something inside to broke?

My psu is a thermaltake tr2 800w...
*** part is that I opened the psu voiding the warranty...

What could have caused my psu to melt its plastic parts?
Did that melted plastic caused the problem? Or a short in the new mobo?
The green LEDs in the mobo lit up one time. Means my mobo is fine...

My mobo is a asus p8v77 v

I have 1 hdd 1ssd
And a hd6950 gpu.

What psu would you recommend?

Thanks...

It's more likely the screw caused the damage rather than the shaking. You don't say if the PSU was plugged into the wall while the screw was floating around inside. Is it possible a washer fell off the screw and is still inside?

Nah the psu was plugged out when the screw fell in...
No washers...

There's a electrical buzzing in the psu....
 
Your shaking of the PSU might have loosened a toroidal ferrite core in one of the coils and it's now vibrating.

When you had the PSU opened you might have noticed blobs of silicone caulking on some of the coils applied during manufacturing to lessen the chance that the core will vibrate within the coil. Sometimes the quality of application of the silicone caulking is lacking. Some coils may even be encased in a rubber sleeve.

I could have posted pics, but well I don't a pc.
Posting this through iPad

The plastic melted like on top of the end part of the psu, where the plug goes through the power point...

It's complicating....

But it's broken alright
