Enermax QC non-existent?

Well I am building a new system right now and ordered a Enermax Liberty 620w and tried to set up the computer and all it did was power up for about 0.5 seconds and then turns off every time.

I then tried to just power up one Vantec Stealth case fan with out anything else connected (including the M/B) and it will struggle to just spin it. Tried a Vantec Tornado and it didn't even budge.

Well I send it in for RMA and got my 2nd Enermax Liberty 620w yesterday, and guess what? It has the exact same problem. I was sent a different one (the serial #'s are different).

So now I have to RMA my 2nd one and pray that my 3rd Enermax works. If my 3rd one doesn't work I don't think Enermax will be getting my money in the future.

Anyone else have experience in poor Enermax quality control?
 
My impression of Enermax QC has always been one of the best.

So.... If this is an all new build, why do you think this is a power supply problem?

Did you start the PSU w/o the motherboard (using a paper clip on green and black) and nothing connected (no potentially defective drives, lights, fans, etc to prevent power up?)

Or is this as simple as, you have another power supply altogether that you put in the build and it fires up no problem?

It's a new build. I imagine the status of pretty much all the parts are unknown, correct? There might be something shorting a rail out preventing the power supply from outputting correctly. Or the board might be just dead. And if the fan is the only thing you have hooked up, that's only a .7A load tops... it may not even meet minimum load requirements.

Forgive my skepticism, but the last 10 years of my life I've had people return product that 75% of the time wasn't defective. I just got a PM ten minutes ago at a forum I moderate telling me that my "tech support" reflects that I'm blinded by brand loyalty. Of course, I had to turn it around on him and tell him that I'm actually blinded by an inherent distrust for end user competence. No offense, of course. ;)

Any more detail you can provide would be great.

Yep did the paper clip thing, only one Vantec stealth fan connected and it struggles to power up.

I do, and I am currently running it as I type minus my x1900XTX, my old PSU doesn’t have PCI-E power, and I don’t have an adapter, nor does it have enough wattage to power the x1900XTX up. I am just running a Geforce 2 MX (PCI) right now.

That’s why I was so shocked that the second one didn’t work either, I have heard nothing about great things about Enermax and didn’t expect even the first one to fail let alone 2 of them in a row.

Thanks for the help.
 
And you tried it with the Enermax and the old GeForce2 MX?

Could be a bad video card. Bad video card, shorts out board, cuases short to power supply.

Fan alone still might not have been at least minimum load for test to be effective.

Possibility?

Yep, tried that just got the same result.

Video Card works fine in another computer, and to be fair the first power supply did power the x1900xtx after about 50-100 presses of the on/off button. It booted fine, showed bios ect. Then restart, had to press the power button about 50x to get it to power up again.

I also tried 2 Vantec Tornados (20w total load), and same result, nothing. It barely moved the blades an inch.

Any other ideas?
 
What mobo? The DFI in your sig?

Yep, currently running it right now. Updated with the latest bios, and it is a great board.

Thanks for the help.
 
Hmm...

You try that Enermax in the other board you have?

The NON-DFI board, I hope?
 
Enermax seems to have ahit or miss QC department.

When you get a good working PSU they are AWESOME, but it seems the odds of getting a bad one are far worse than with most other enthusiast geared manufacturers.

I'd even go so far as to say that Enermax has become synonimous with the word "Poof!" on several enthusiast sites. (Because thats the noise half of them emit when you power them on for the first and only time)

:p

Haha exactly, that is what happened to the 2 I have had so far, hoping the third will work.

Update: It didn't power up the other mother board.

Thanks for the help all, wish me luck :)
 
Update: Third times a charm!

Works great, still very skeptical of Enermax though.

Lucky you!! I'm on my 4th Liberty now, well almost on it, I really can't be bothered pluggin it in as it'll probably blow up like the last 3!

Man Enermax needs to learn how to do some quality control.

3 dead in a row seems mighty suspicious......I would bet on an underlying issue with the system.......or on the way outside a strange incompatibility....but more likely system issue.
 
Check this out....

I heard this story from someone at my current job about a product that someone at my previous job had installed.

System built and running.

PSU switched out.

System would not post. Fans on PSU twitched for 1 second and then shut down.

PSU switched back out and computer ran fine.

Replacement of upgrade PSU was ordered, installed and once again would only twitch on power up.

Turns out that the short-circuit protection was working on the replacement power supply! There was no such protection on the original power supply. There was a short in the CCFL inverter that was preventing the new power supply from powering up.

DOH!
 
ahah this thread is hilarious.
First, there is no way that you got 3 bad Enermax PSUs. I think all 3 were good. The reason why it switches off after 0.5 seconds is that you have a shortcut somewhere! You may wonder why your test with only one fan did not work: this is because only one fan does not draw the minimum power required on each rail for the correct operation of your PSU. So stop to think it's a PSU problem, and look at your other components. I would try to run it out of a case, to prevent possible shortcuts between the mobo and the case. Also try to run with only the essential components.

You mean shorts, not shortcuts bahaha.
 
I love how ONE problem suddenly becomes a company wide failure. I'm sure you did everything PERFECT, right? You couldn't possibly be the reason for all of these failures, right? Of course not....


I've had numerous Enermax PSU's and they've all performed flawlessly. When I first attempted hooking up my PCP&C 1Kilowatt guess what...it did the exact same thing you claimed the Enermax did in your OP. Did I come to an online forum and complain? No. I corrected my mistake and moved on.

I would have thought underlying system problem too, except for one thing, my other PSU a Jeantech Arctic 600 runs the same system no problems 24/7. Only difference I have noticed between my currently working Enermax(touch wood) and 1 of the previous ones is that this one is undervolting the 12v (11.92) and the other was exactly 12 give or take .01 before it blew. The Jeantech was/is 11.9. Anyway, I seem to have a working Enermax now, but the Arctic stays as a backup, as I simply do not trust Enermax's reliability.
