Antec NEO HE warning...

Status
Not open for further replies.
well i've experienced 2 random shut downs of the computer today, one happening about a half hour ago....so i took off my overclocks for my cpu to see if it was that....looks like i'll probably have to sit down and find new overclocks with this psu to find its limits, so i know that it's as stable as can be
 
I had a ton of best buy credits sitting around so I decided to pick up the NeoHE 500 watt PS that they were selling at the store at the time. It was between that and a TP 2.0 430 and I figured I'd get the 500 just to be safe, so...

I hooked up my P180's case fans - just the fans, nothing else - to it to see what their noise'd be like, and the PSU didn't do anything when I plugged it in and turned it on. Unless I'm doing something wrong (and considering the gaps in my computer knowledge, I just might be) that's definitely not good. :confused:
 
What kind of motherboard and did you have another PSU running all of the same parts prior to installing the HE?

I'm not sure they'll start up with just FANS on it, though I could be wrong.

We're investigating what is going on. So far 6 known issues (including TheSaint) with the NeoHE and 1 brand of motherboard. Going from past experiences sometimes it's the PSU sometimes it's the motherboard.

edit: known means people have called/emailed in to us.

This forum is awesome. :D Got the AntecRep checking things out. :cool:
Just got my HE550 from the egg to go in my P160. Bulding my system slowly so it will be awhile before I try it out with a motherboard, but I happen to have an Antec brand power supply tester (20 pin connector with a pigtail and led that lights up when the power goes on and test points for 3.3, 5 and 12v and of course some resistance built in. Not really a tester but it makes it easier to turn on the supply without having it attached to a motherboard or shorting any pins) and of course a DMM. But it's a 20 pin tester. Seems to me like it would be okay to use that to power it up and test the rails, but I wonder if someone else has a different opinion. If I am guessing correctly, 12v1 is on motherboard connector, 12v2 is first 2 6 pin connection points and 12v3 is last 3 6pin connection points. Or am I waisting my time checking each rail?

Did you jump the PSU so that it would start without being plugged into the MB? I cant remember which two pins on the ATX cable you have to connect, but without doing that the PSU will never turn on.

Green and black.
 
i had read that you're not supposed to leave the psu jumped and running for too long. is there a safe runtime for voltage testing?
 
it depends on the minimum load for each of the rails. Sometimes, the min load is 0, so it's ok. In your case with just hooking up fans, you have a load on the 12v, so check if the 3.3 and 5v rails have min load.
 
where are the minimum load specs listed? are they usually on the outside of the psu or in the manual?
 
Could it be because of UPS beating the hell out of your package?
Click to expand...

Good one!! LOL It's very possible, but I didn't bring it up with Newegg. I just wanted a working PS.
 
OK johnny. Thanks for letting me know I'm way off. I surmised that info based on the reccomendation in the HE550 owners manual where it suggests that in a dual card setup you use one of the 2 left most connectors for one card (12v2?) and one of the 3 right most connectors for the other (12v3?) and I'm pretty sure I read somewhere that 12v1 is dedicated to the motherboard connectors (24 and 4/8 pins). I'm no electrical engineer obviously. Does it matter to check each 12v rail or are they all going to be the same voltwise. Obviously each one can be delivering a different amount of amps depending on what it's powering. I was just thinking that the guys reporting rail voltages from their motherboard bios are really only seeing the rail that goes to the motherboard. What about the others. Can they vary in voltage from each other? What about the question on my Antec psu tester? what do you think? OK to power it up with that? It's a pretty neat deal that also provides a small load for it to work against. It's just that it's made for older 20 pin power supplies.

12V1 is the motherboard, 12V2 is the 2x2 connector and 12V3 is other.

You would want to test ALL of the leads. Each rail has runs through it's own MOSFET, so voltages can vary.
 
ASUS techs tell us to be sure that the 4-pin molex is plugged into the board. We're still checking this out. But if you have a NeoHE and an ASUS board please make sure that you have that plugged in.

Can we send Asus a collective "DUH" for the "Is it plugged into the wall" type response? ;)
 
Just got my 550HE
my plan was to replace my fortron bluestorm with it, but all these issues have had me worried. So I plopped it into a server Im building

12v is at 11.29v
5v is at 4.86v

This is on a 3200+ and a Tyan k8e motherboard, 2 harddrives, 1 cd, 1 floppy. 2x 120mm fans, 2x 60mm fans, Nothing else

I plugged in the molex adapters on the ones farthest from the ATX power cable(1 and 2) no others are populated. If it were in my machine id have to deal with the PCIe vid card connector.

Will be testing this system thoroughly so we'll see how she holds. I dont like those voltages tho
 
Update
Major issue

Ok so i build the server, pop it in, turn it on and go into bios. I leave it in the pc health section of the bios for 10 minutes then the machine powers down. At first I thought it might have been temperature setting I placed. so i try turning it on. Nothing. I try several times and it finally turns on. I get into bios, I goto pc health, temp says 30c, then the machine instantly shuts down.

I move the powersupply cables alittle and the damn thing SPARKS internally. at t his point I unplug it and yank it out of the system. like hell am I putting it in any machine. If the hardware is fried I will be thoroughly pissed. Antec lost all respect from me
 
Please don't flame the AntecRep; he/she's here to help.

This sounds like a big defect for some reason, and I hope antec gets it fixed, because on paper, this is a great looking PSU.

Not really, I think he means the four-pin molex that's usually only needed for SLI operation. Asus says in the manual to keep this unplugged if you're running a single video card.

So much for the quality control of the factory which manufactures recent Antec-branded PSUs. One out of every few PSUs from that brand developed problems of one kind or another..

I haven't had very good luck with Antec. I've had two of them die on me. One was just over a year old, and the other one died within a few days of buying it. I've got a Thermaltake right now that seems to be doing ok. I think for my next system I want to get a Seasonic.

that was the molex that gave me the most trouble...i had everything else wired and ready to go, then i saw that and remembered i needed to plug a molex into the motherboard that sits near the vid cards since i run my 6600gt's in sli....made me redo EVERYTHING and luckily i had a y splitter for a molex or else i woulda been out of luck....the one complaint i have is that the NeoHE550 could have used another molex line, because 2 with 3 connections each isn't enough...

Doh, you edited as I was touching up the picture ;) Anyhow:

You really think they mean the four pin drive Molex up by the slot? That doesn't make too much sense if you're not using SLI as it just provides extra 12V to the video cards via the slot. I mean... why would that make a difference? If you have a single 6600 that doesn't even require an additional 12V and it works with another power supply, why would the Antec require it?

Hmm...

If anything, I would think that would CAUSE a problem since the 24-pin gets power from 12V1 and the drive Molexes get their power from 12V3.

Hmmm again.....

Yes, he was talking about the Molex socket that's next to the PCI-e slot. That Molex connection is needed only if he's going to use two cards in an SLI configuration.

On the other hand, the four-pin square ATX+12V socket must be connected to the power supply unit in addition to the 24-pin ATX power socket connection. And all of those newer mobos require a PSU with a 24-pin ATX power plug and a 4-pin square ATX+12V plug. Do not use a PSU with an older 20-pin ATX power connector, even with a 20-to-24-pin adapter, on these motherboards.

But we're not talking about an older power supply.. we're talking about a NeoHE which has 24-pins and a 2x2 which is why I said in my post (before I edited it) that anyone that knowing hooks up only 20 of the 24-pins in an A8N-SLI board needs to be hit over the head by their own power supply. :D
 
Newegg is getting an RMA from me, I'll be out something like 17 bucks + shippingl.
this isnt the first time I've had issues with antec. just the most extreme.

Since I needed to make sure the hardware was fine i drove to fry's and bought an OCZ powerstream 520. $113+tax

I was going to get a PP&C From monarch computers but they're stock updates are sketchy, The PP&C SLI Express says 4-5 days delivery, even tho im in the same state I cant risk them sitting on it for 4 days. And the powerstream's stock wasent updated, just said Good luck first come first serve.

Machine is up and running and in the bios.


My god it has green led fan. I thought it was blue.... Thats ugly.
 
I tested my 500w last night on a molex that had 2 case fans and a cc attached.

System:
P4 3.0c
1GB Kingston pc3500
MSI PT880 Neo
AIW X800XT @ 15% overclock on core/ram
2 dvd burners
3 case fans
2 WD Raptors in RAID-0
cell phone charging via usb:p

They do? aww shit.....mines been running a while w/o it pluged in ive got the ultra-d
 
Well i've returned it to newegg. Should arrive tuesday. Im out $10 shipping, $17 restocking fee. And time. Antec PSU's, never again.

Are you getting another PSU from new egg? If so, what?
 
SomeoneWhoIsntMe said:
Fuck, I need to get a floppy connecter all the way over to the first PCI-E slot?

The PSU only has a splitter for two floppy connectors, and I need to have a floppy drive plugged in too. This might end up looking really retarded.

Yes, it could, unless you make your own custom cable. ;)
