Power off

[mario]

Last Sunday while working on one PCs of mine (in use without problems since several years) the entire power in my flat had a shut-down by the main power differential switch.
By various tentative I discovered it must be that particular PC causing the power to go off.
Other devices left running alone do not cause it.
Is it possible that PSU causes it; or could even be caused by some other components (MOBO, HDD ecc.)?
Thanks

PSU's vary in quality so much I wouldn't be surprised if the PSU is the problem. Also, after a few years of solid service, you should be thanking the fates that something hasn't happened. ;) At the 3-year mark, I usually do a once-over on a system because I know that's the max up-time of any system that isn't being constantly maintained/upgraded. Replace the PSU. One PSU every 3 years ain't bad! :cool:

Thank Saphalline
I will replace PSU in any case with a good brand I have used in other assemblages (normally Enermax) following your suggestion.
I remember once in this forum someone suggested to avoid modular models with detachable cables (that Enermax offers as well); it was some years ago - if I'm not wrong - , is it still so? I was attracted by these possibillities to avoid too much disordered cables in the case.

Modular cables in a PSU are an inherently bad idea. Myth #3 (http://www.pcpowercooling.com/technology/myths/) from the website of PC Power & Cooling will give you info on that. You can also search their site for more gems of wisdom - they are quite eager to inform people about the pitfalls of PSU designs.

I tend to stay away from modular plugs, because I've heard too many horror stories. One of them was even here on the forums! :eek: A lot of gamers went for that first X-Connect PSU, and it was such a POS. Problems all over the place! Anyway, because modular plugs are a bad idea to begin with, I will always stay away from them.
