Weird Zalman 750HP power issue

post #1 of 9
Thread Starter 
So, a while ago I thought I'd turn on my PC after a couple of months. But it didn't boot up. The small ASUS logo on my motherboard wasn't on either. So I thought I had a dead PSU. So I bought a cheap Antec 400W PSU. It worked.

Now I've bought a GPU, an ASUS GTX560 Ti, the PSU apparently coulden't cope. So I took a look at my "old" Zalman 750HP, but there's no glass-fuse or anything? Wth? But, when I plugged it in, I stupidly touched it and it properly woke me up...

So, the PSU has the power, but it's not transferring it to the motherboard...

Anyone any jdeas? I'm Ok with electronics so any basic fix is doable.

Thanks for reading,

Ben

After watching a video on YouTube, the guy said this PSU shuts itself off instead of dying or something? If so, how do I turn it back on?

These are all of safety features;

Over-Voltage Protection, Over-Current Protection, Short-Circuit Protection, Under-Voltage Protection, and Over-Temperature Protection.

I took the PSU apart, it seems that it has no glass-fuse or anything similar...



This is what the PSU looks like from left to right.

Ideas?

I just put it back together and I did the paperclip test with a load of 3 fans. No result. In the tutorial, they said it was dead if the test doesn't work. But I have a hard time believeing that... Since I actually felt the power with my own left arm, lol.

I wouldnt risk blowing something up with it. This is probably one of those moments that its probably better off in the trash.

You can test it but only rudimentary tests... First off, if the PSU has something happen to it, it will turn off for a bit, let it do this, if it stores any more energy, you might get more then a wakeup call.

(Do this at your own risk, it is high power we are talking about more then a wakeup call )


You can test it by taking the green wire (the only one) and taking a spare wire or what have you, put it into the green "jack" and ground it by attaching it to the black wire hole - any one will do.... this fools the PSU into thinking that its attached to the motherboard. When you do this it will allow it to be turned on and power various things, i do this for fishtanks because i use fans to cool them down, PC fans are everywhere in my house so i do this a lot... - back to the point, grab an old HDD, or something and plug it in... if it works, it could be your motherboard...

But like said above, its better you just throw it away (legally) and get a new one.

No. I refuse to think it's dead. Pretty much impossible.

Thanks, but that's exactly what I did:

FSP Epsilon based unit... (like OCZ's old "GamerExtreme!") the Zalman heatpipe improved that platform a lot. Cooled better, reduced ripple and upped build quality. But, you know, crap is still crap no matter how you re-package it;

It's based on an unreliable platform. Probably died, sorry.
