Greetings
My old 350W FSP-350GLN(80) PSU was working fine with my current computer for few years(and previously with few other computers as well). Nothing has changed in setup but since last few months I am getting problems while trying to boot PC.
What happens, is that PSU starts and I can hear fans, both PSU, CPU, MOBO and GPU. I can also hear HDD scratching and normal starting sounds. But DVI monitor claims that there is "no signal". Moreover, neither USB mouse nor PS2 keyboard does flash leds like it should do upon boot.
I have to turn PSU switch on and off multiple times hoping that it will start at some point. Sometimes it takes just few clicks, sometimes I have to wait for few minutes before it can start. Once things go off, everything is perfect, computer is very stable under highest loads and fans are quite quiet. Restarting using OS restart option or restart button never cause any issues and works instantly. But (cold)powering down makes the issue come back.
It's quite old PSU, probably at least 15 years old. But it never caused any issues and it was quite quality product by then. I didn't use it all the time and it was never stressed. I don't have multimeter but according to software, voltages are pretty perfect.
PSU internals look fine, fan spinning normally, almost no dust, capacitors not bent, no oxidization, no smell.
I own a second FSP-350GLN(80) that was never used, and was stored in mint conditions and it's unable to power my mobo, there's just no reaction at all(while passing paper-clip test and working fine with +5V/+12V from molex). Both were purchased same time, and as both are not working properly, I think that it's just age-related problem.
But essentially, what could be causing such behavior? I know that +5VSB is used for USB/PS2 and I know that computer somehow behaves like it would be in ErP state and wouldn't be able to fully recover(even when I never used ErP). Oddly, I do own some blacklisted-noname PSU's that are even older than my Fortrons and they have no problems with powering my mobo.
added:
Note, I probably don't plan on fixing my Fortrons so question is out of pure curiosity. I can get used Seasonic G360 for around $15, would that be good replacement, what are opinions on those Seasonics(I've read here that G360 is a bit different than other Seasonics G)? I can even pick from different Seasonic G360 revisions, I guess they are alphabetical: BGP360FSJBW, BGP360FSJCW, BGP360FSJDW. Sadly, probably newest D-version is also in worst visual condition.
