AOpen AK77-333

[Gianni]

This board has worked hard and even if 4 Lelon were completely out of spec it was working fine.
I recapped this board and 400W Techsolo PSU to build a PC for my son's school.
Me and other parents are helping the teachers to maintain and develop the computer room of the school.

We are going to install Ubuntu on this one, like most of other PC.
Ok here some pics of the board with bad Lelon and good Pana after recap.
In one picture you can see the MOBO and PSU under test. Few pics of Techsolo after recap too.

@ zandrax: this PSU has passive PFC, the big coil placed in front of heatsinks. The EMI filter is complete and there is a rectifier bridge, not the 4 diodes. I resoldered the cables and some other things. Unfortunately I can't take more pics because I brought everything at school yesterday.
I ran Memtest86 and everything was OK.

By the way I was wrong in the Techsolo post, the cap I identify as LOWES brand was a Unite, the complete text was LOW ESR but I read it only when I removed the cap.

I don't understand why there were a lot of good UCC and Rubycon caps all around and those 4 crap caps

So it's a keeper: at least is quite decent.

I like the intel cooler on the amd processor

@ 370forlife: damn you noticed that
On the heatsink was attached a fan that was not original, was smaller than heatsink and attached with only a screw
The only fan I had in my rubbish was a Intel, I had to cut the plastic brackets to block it on heatsink, than I glued it in 4 points to be sure it doesn't fly away.
