bestec failure

post #1 of 9
Thread Starter 
I just had a run in with a 250Wtt bestec 125 psu. I was at my brother's house & was installing the 5850 I just got in my pc & found I had run out of power connectors. I asked my bro if i could steal one out of his pc until I could stop at a parts shop. He got worried that i would fry his computer if i did(he's clueless about pc's) but agreed as long as his computer was put back exactly as it was when I got my own connector.

Well when I put it back the way I found it the pc failed to turn on. Look at the psu & yup its got a flashing green light, I try jump-starting it & it actually boots up & i tell him ok its up & running again. well when he goes to use it later it has died again. He freaks out & blames me for it. At first I think maybe it was my fault somehow so i pull the psu & do a quick inspection, it's got a blown cap so i look the psu up online to try to find a matching replacement(he wanted it as it was). Well I start finding horror story after horror story on this psu online. I find out that it has a lovely habit of frying mobos when it dies. So I convince him that it's in his best interest to get a better psu.

I go to the local parts store with the old psu just to make sure i don't get an incompatible one. The owner was able to guess that it was a bestec the second i walked in the store. That made me do a double-take, how the hell are these things still being circulated if they're that horrible.

This ^^^
They usually come free with cases, or so insanely cheap people who don't know better say "Oooh! Bargain! Only $20 for a power supply! Much less than the $80 for this Antec one!" And then 6 months later, they need a new machine...

Bestec are not universally terrible.

They had one model, the 250-ATX-12E, that had a terrible design of the +5VSB rail, such that when the computer is off and the +5VSB is the only rail delivering power, the +5VSB runs at 6-7V, which will fry your motherboard over time. This was the cause of so many eMachines failure.


Their other models are not that terrible. They aren't great, but they aren't terrible. And even the 12E isn't going to arbitrarily blow up... Unless you grossly overload it, which a 5850 likely did since you really need a quality 400W for that system.

um the 5850 never touched his crappy psu, I have a 500 Wtt that's running my 5850 just fine, I simply didn't have a power connecter free & borrowed one from his.

Thankfully his bestech wasn't the 12e, I was grateful for that because it would have been me buying him a new mobo since "i was the one that broke it".

If someone takes my power supply and when he returns it it no longer function, then that person owes me a psu.

That being said, Bestec power supplies DO suck horribly, they were put into a lot of OEM computers.

any pc i see an OEM bestec in i automatically replace, my father's HP media center pc for example, i opened it to clean the dust out of it after 6 months(god it was disgusting), i dusted off the power supply label, and low and behold, i see the big bold letters BESTEC on the side, i sent him out to tiger direct for a new 400W psu, end of story, he now runs on a corsair CX400
