In a recent thread here ("") I was testing out a new tool to quickly
diagnose whether a PCs issues were PSU related. Turns out the power
supply tester and the PSU were defective (behold the power and of the
multimeter). Anyway, The Antec TruePower 380 PSU is only about 26 months
old and seems a tad young to be dying seeing as my other Antec TruePower
380 is over four years old and running perfectly. The motherboard in the
system with the bad PSU is one of several Gigabyte boards I've owned
that have been affected by the bad capacitor issue. I'm wondering if the
buldging caps on the GA-7VTXE+ board could have caused the early demise
of the 5V rail on the PSU?
More likely, the bad caps in the PSU caused the demise of its +5V
rail.
www.badcaps.net has lots of info about caps, and one of the brands
they dislike is Fuhjyyu, which are common in TruePowers and
SmartPowers. If you find one cap bulging, change all the others that
are of the same brand, color, and markings (except for voltage and
capacitor values) because they'll likely fail soon, too. With my 300W
Antec, it took just two weeks for a cap that tested and looked good to
fail after I replaced the bulging one next to it.
