Background
My FSP AU-500 served me well during 5 years with no problems.
Then all of a sudden my ASUS main board warned for inconsistent power and then shut down the system. After a few shutdowns I changed to an older corsair CX400 and all was well.
Tried the AU-500 in a another system to see if it was the anti-surge in the ASUS motherboard causing the problem. Worked well on a gigabyte 880g for a few hours with some load on it and then again it restarted. Tried again and this time it shutdown not wanting to start at all.
As my warranty was nullified during RMA, due to damaged package during shipping, I now have it back wanting to try and fix this.
Description
5vsb ok (5.025v no load)
Intermittently refuses to start. Fans twitching but nothing more.
When it do start it stays on, at least long enough to check voltages.
Testing
With a 5w load i have the following
First
-12: -12.262v
+12: 12.069v
5v: 5.065v
3.3: 3.334v
VSB 5.020v
PG: 3.746v
Second
-12: -12.424
+12: 12.460 and climbing to 12.494
+5: 4.904
3.3: 3.334v
VSB: 5.02v
PG: 3.505v
Caps (All measures in circuit)
4 3300uf 10v Capxcon
2 3300uf 16v Capxcon
1 2200uf 16v OST
1 ? Brown
1 47uf 35v Capxcon near FSP IC 6600
(57uF 0 esr)
1 4.7uf 50v Capxcon near FSP IC 6601
(5.2uf 3.3esr)
1 100uF 50v ?(Nippon) Brown near mosfet
1 270uF 400v Nippon-Chemicon
There is no sign of bulging caps and in circuit measures of the larger Caps does not reveal anything had 7600uF and 0 esr, but again its in circuit.
It could be a problem with the control circuits fail-safe triggering on a false reading or damaged. I´m looking at the two caps near the FSP ICs.
I am surprised to find this many Capxcon in here.
Any suggestions?
