[Solved] New power supply issue

Just wanting to do some upgrades to my weakling eMachines w3650 I've had for four years because I can't afford an entirely new system, so I went shopping and found Processor, Video Card, and RAM at a very good price.

Everything went well but my power supply ran a lot louder. Found out I need a more powerful one to run all the new stuff.

The old PSU is a 300w that came with it.
Specs as follows (as displayed on label):
Input: 100-127V-6A, 200-240V-3A 50/60Hz
Output: +12V / 15A -12V / 0.8A
+5 V / 30A +5VSB / 2A
+3.3V / 28A

+5V & +3.3V 180W MAX
+5V & +12V & +3.3V 288W MAX


The new PSU is an Alpine 750w.
Specs as follows (as displayed on label):

DC OUTPUT
AC INPUT: 115V/230V |+3.3VDC | +5VDC | +12VDC | -12VDC | +5VSB | PS-ON | COM | POK |
, 7A/4A | 26A | 36A | 38A | 0.5A | 2.0A | REMOTE | RETURN | PG |
Frequency: 50/60Hz | 734W | --------------------------------------------------- |
Max Load: 750W


Old PSU connected to everything with a 20-pin ATX main to the motherboard (mobo can handle 24-pin as well), 4-pin ATX 12V also in the motherboard (i imagine for CPU), SATA for hard drive, and 4-pin peripheral for my cdrom drive. With a few extra connections left over, but it ran fine. That's how it came stock.

New power supply came with 24-pin ATX main, 4-pin ATX 12V, multiple SATA connectors, multiple 4-pin peripherals, and even a 6-pin PCI-Express cable.

I connected the 24-pin main and the 4-pin 12V to the motherboard. SATA into the hard drive, peripheral into the cd rom drive. Everything was as it should be.

I try to turn the power on, it fires up for a split second, then resets, then tries, then resets, then just idles. The PSU fan and CPU heatsink fan are still running (and yes I made sure to use thermal paste when installing new CPU) quietly and beautifully, but i hear this ticking sound coming from the motherboard. No boot. Can't even get to the BIOS screen.

I tried removing video card, replacing old processor back in, I only have 1 stick of RAM so I did the remove then add 1 stick trick, I tried firing up without a connection to the hard drive (no connection from HDD to motherboard either) so I could try to at least get to BIOS screen. It worked ONCE. And I got to BIOS. All the voltage, amps, fan speed, temperatures, everything was well within acceptable parameters. Then it shut itself off and began with the complications in my last paragraph.

Removed it, put the old PSU back in, fires right up with no problem.

I know most times when people say "ticking sound" the first response is "you may have fried your hard drive tinkering in there or knocked something loose". But here I am using the old power supply. So I imagine my hard drive and everything else is just fine.

I know faulty product is a possibility, it could happen to anyone. But since it's brand spankin' new, I'm trying to figure out if it's something wrong on my end or if it's a faulty PSU and just get it exchanged.

BIOS for the mobo is up to date. CMOS battery has been reset. Everything runs fine with old PSU, just not the new one.

Any thoughts?

Thanks in advance.

You've done everything right in diagnosing this. Sure sounds like a faulty PSU to me.

That's actually a relief AND frustrating lol.

A relief because you agree it's not me being a technotard.

Frustrating because I want to comfortably run all my new stuff.

Crap

Never even heard of Alpine. Buy something that's a known name brand, something at least 80+ bronze rated.

I'll get it exchanged. If it works, I'll mark this as solved. Until then, I'm open to suggestion.

Alpine is bigger with car audio and electronics. Which tend to be good from my experience (helped an ex gf few years ago install a 2000W sound system and two 18" subs in her car....everything worked beautifully and still bumpin' like mad). Figured I'd try them at this as well.

I must be one of the geeks who approves.
I've never heard of Alpine either. Antec and Corsair are both quality brands with some inexpensive models in their lines.
If the new video card you bought does not even need that PCIE power connector, a 380W Antec Earthwatts or 400W Corsair CX would be sufficient; in fact even if it does need one of them, either of those PSUs should do. Online, they should be no more than $45.

Edit: I've heard of Alpine audio. I strongly suspect they are entirely different companies. In any case, most of even the better brands do not actually make their own PSUs.

LOL

It's not the same company, trust me. :lol: 

Alpine audio does not make computer parts. It's a generic POS.

That generic Alpine PSU brand seems to be specific to the UK.

All of the symptoms, you've described, indicate a defective PSU.

Tried the PSU in two other systems and it did the very same exact thing as in mine. I think we're all in agreement that the verdict is it's a defective unit. I'll mark as solved and get it exchanged. Thanks to those who commented :)

I kindly request that you do not assume anything. Once I told my girlfriend what was going on with it, she offered to throw in some extra cash to get a better one. So the route that will be taken is to get a refund and get a different one. Probably going Corsair this time. I found one that seems a fair price on newegg and the majority of user reviews are positive.

As I said, do not assume anything. Your haughty attitude only makes you seem like a troll.
