Does anybody know if Antec's European customer service team is working this week? When I sent a message on Tuesday (27 December) asking for an RMA, they opened a ticket, but I've not heard from them since, despite sending a reminder yesterday.allenlux wrote:I think I will try to return the PSU.

Antec NeoHE "High-Efficiency"
Moderators: NeilBlanchard, Ralf Hutter, sthayashi, Lawrence Lee, Devonavar
I still haven't heard anything back from Antec, so I re-contacted Overclockers.co.uk, who sold me the P150 case with this PSU.
This was their message this morning:
This was their message this morning:
Does this make sense? I've not yet seen a clear explanation of the problem with the Antec Neo HE PSUs when used with Asus motherboards, but nothing that I've read so far would indicate that the problem could be solved with a "converter".We expect to receive converters for the PSU's shortly which will enable the power supply to be used with the Asus motherboards. As soon as these converters are received by us we can send one out to you.

So far I haven't succeeded in getting an RMA either from Antec or from the retailer.Rory Buszka wrote:Just return that case.
As far as Antec are concerned, I hope the delay is just because of the holidays. In the past, I've been impressed by the willingness of Antec employees to participate in this and other forums, and I expect the company will sort this out. I just wish they would hurry up.

This is the reply I just received from Antec Customer Service:
This may be correct, but it's not exactly an incentive to buy Antec PSUs in future, since other makes seem not to have this issue.
If I read this right, they are basically saying that I bought an inappropriate power supply, and there is nothing more to be done about it. The implication is that the "fixed" Neo HEs will still not work with my motherboard.First we would like to apologize for the non-prompt response.
It is our understanding that Asus A7N8X motherboards is AMD K7 based, and does not comply with the ATX12V v2.x design guide (because it predates it considerably). So this will not work properly with the Neo HE even though the power supply is backwards compatible to ATX12V v2.01.
Our return policy works in a manner that we will replace a defective item with the same exact model.

Actually, it may be that very few of the ATX12V v2.01 (and later) PSUs will work for you. The reason is that your board draws considerable power from the 5V line for the CPU. The available power on the 5V and 3.3V lines is much less than it used to be on the older spec PSUs. Just have a read through the appropriate section in the PSU fundamentals article. Your motherboard should work with any v1.3 PSU, however.allenlux wrote:This is the reply I just received from Antec Customer Service:

of course they do, but others also will stand behind their out of box all defective items. Looks like antec has collected enough money from us by selling overpriced cases (p180) that they will no longer care about their customers.

This is an interesting point which I think goes to the heart of the problems we are having with the Neo HEs.
I looked at the 2.01 guide on http://www.formfactors.org and I see on page 13ff for "typical" PSU power distributions, on the +5v line:
250W 18A
300W 20A
350W 21A
400W 28A
However, the Neo HE 430W has on the +5V line only 14A maximum. So it seems quite far away from the "typical" values in the ATX 2.01 guide. Certainly other mainstream new PSUs have much higher ratings on the +5V line. On the other hand, your very interesting article on power distributions within 6 PCs showed that the 6 tested systems drew no more than 3.0A on the +5V line.
The ATX design guides don't impose any minimum output power level for the +5V line, so Antec may simply have decided to go for a much lower value than other PSU manufacturers. This decision is not unreasonable, but it has caused a lot of angst for people who read on the Antec website that the Neo HE is "backwards compatible", when it's now evident that it interprets the 2.01 guide very differently from other mainstream PSU manufacturers.

Actully, our review had a factual error:
We reported that the NeoHE is ATX12V v2.01 compliant. However, checking Antec's site now, I seed that it is listed as v2.2 compliant -- and backward compatible with v2.01. I don't know whether we made an error -- or whether this info was changed since we posted the review.
The v2.01 (June 2004) guide's max current for 5V that allenlux quotes are quite different from the v2.2 (March 2005) guide numbers:
------- v2.01 v2.2
250W 18A 12A
300W 20A 12A
350W 21A 12A
400W 28A 14A
450W ---- 14A
There have been vast changes in power distribution guidelines across the 12V vs 5V & 3.3V lines since v1.3 of the ATX12V spec. There is no question that some of the newest v2.2 PSUs will simply not work with older boards created when v1.3 (or earlier) was current. The reverse is also true -- some new motherboards (when equipped with high power CPU/VGA etc) will not work with older v1.3 PSU.
This may be part of the issue for some people -- those with older motherboards & CPUs -- but most of the misbehavior I've heard about seem to be on current K8 and 775/478 boards.

Antec is saying this is not a defect, they're saying we never claimed it would work with a mobo that needs a v1.3 PSU. I tend to agree with them technically, especially if they know this is normal behavior for all NeoHE PSUs.spolitta wrote:of course they do, but others also will stand behind their out of box all defective items.

But for desperately needed goodwill in their mess right now, it would have been wise for Antec to offer a swap for another PSU that would work with the older board/CPU.
I swapped my parts from the P180 to the P150 tonight, and the Neo seems to work. Been folding for a couple of hours now.

I suggested this exact thing in a strong way after I was shipped the 2nd one that would not power things up and was then told they thought they had an incompatibility somewhere..

I thought it was a crock then to further inconvenience their customer(s) at the time and think even moreso now. What a major bad entry to the public of what could have been a great case/psu combo.
I think some others have the right idea, non-antec for power supplies for me for a while; they will have to produce a couple of models before I'll be back for a PSU. Besides my seasonic is pretty nice.
Oh BTW: p150 went back to Newegg last week too. No restocking fee
How liberating.

my system is currently running on a Seasonic powersupply with a rated +5V output of 30A. the NeoHE 430 powersupply as present in the P150 case has a rated +5V output of 14A.
is this enough for my motherboard?
i want this P150 case for it's silent potential (adding a ps-duct to it, isolating the fans, quiet ps, rubber hd-mounts, etc, etc.), but seeing these rating-figures the NeoHE powersupply will not work with my A8N-SLI Premium board.
i just found in the manual of my asus a8n-sli premium board, that it expects a atx 12v v2.0 compliant powersupply.
so that probably won't and will never work with the antec neohe 430 atx 12 v2.2 compliant powersupply.
guess, that means no p150 for me. unless i am willing to ditch the neohe right away and replace it with a silentmaxx eg.

Not so. V2 and V2.2 are similar enough. V2.01 had these changes from 2.0:sanse wrote:i just found in the manual of my asus a8n-sli premium board, that it expects a atx 12v v2.0 compliant powersupply.

1) Updated 3.3 V remote sense pin # on the main power connector
2) Updated 12V2 DC Output Noise/Ripple information
3) Removed -5V reference
4) Updated 5Vsb maximum current step
The main changes in 2.2:
5) 5V standby current increased (from 2A/2.5A max/peak to 2.5A/3.5A)
6) 4.5.1 Added High Current Series wire terminals for ATX Main Power Connector
7) 4.5.2 Added High Current Series wire terminals for +12 V Power Connector
In any case, I am running a P150 system with one of those Asus a8n-sli premium boards and a revised NeoHE430 right now. Other components are 2x3800, nV6800GS, 200GB Samsung, 2x512mb RAM, optical, floppy, several fans. Have been doing so for several days; system is under long term stress testing/burn-in. ~190VAC peaks w/ 2Xcpuburn and 3Dmark05. No trouble of any kind so far.

i had contact with a supplier overhere in the netherlands today and he assured me, that the p150's he ships are from the latest version...
maybe i should give it a try, so i can finish this project.
I just received my P150 tonight from Newegg. The warranty seal was also broken along the opening. It's pretty obvious that this was not "accidental" due to shipping (as was said in another thread), the box was in perfect condition and every item in the case was still secure and nothing showed signs of being jostled. The first thing I did was take some pics with my digital camera so I'd have proof it arrived like that.
I have no problem with Antec opening the case to fix the PSU (in fact, I hope they did), but it would have been nice if they resealed it. I assume Newegg wouldn't go opening items up like that, unless instructed by Antec to perform some kind of fix.
I will test it out with my Asrock motherboard when it arrives later this week. *Fingers crossed*

It seems pretty clear to me that a few people who tried to use this power supply with significantly older systems are giving this PS a bad name. As SPCRs own testing implies, any v2.0 or higher board should do just fine. Further, that the problems with this PS (if any) have been resolved and those that are experiencing problems are using it out of spec.
v2.0 came out in Febuary of 2003! Anyone building a new system (or even upgrading a relatively new system) should clearly not have any issues with this PS.

Yes, the problems with NEW Neo HEs are probably resolved, but that doesn't change the fact that there still are lots of old Neo HEs in the channel.ddrueding1 wrote:It seems pretty clear to me that a few people who tried to use this power supply with significantly older systems are giving this PS a bad name.

According to the ATX design guides quoted above by me and by MikeC, the "typical" +5V maximum currents are:
----- v2.01 v2.2
250W 18A 12A
300W 20A 12A
350W 21A 12A
400W 28A 14A
450W ----- 14A
Let me ask 2 questions now:
- if I have a motherboard from 2003 which needs say 20A on the +5V line, is this motherboard compliant with ATX v2.01?
- if I have a PSU which delivers a maximum 14A on the +5V line, is this PSU compliant with ATX v2.01?
(I'm aware that these "typical" values are not mandatory and that we are not talking about compliance in a legal way, but in a common-sense way).
How can I tell if my old Gigabyte motherboard is applicable with the NeoHE? It's a GA-8ITX, the specs of which are here:
http://tw.giga-byte.com/MotherBoard/Pro ... A-8ITX.htm
The specs list the following concerning the power supply:

Perhaps I should have thought about this before I ordered my P150ATX power connector, ATX 12V connector and 3.3V AUX power connector

BTW, for anyone posting here, the proper standard is ATX12V. ATX is something different (but related).
Here I add some info, in addition that given in Neo HE Poll thread.
I ordered my two systems on Dec 20. When I ordred them, I was aware of the problem of Neo HE 430 with ASUS AMD cpu. But I did not find it has any problem with intel CPU. These sytems are basically the same
case P150
mb ASUS P5WD2 Premium
cpu intel 830 duao core
ram 2 kington 1gb
hd wd SATA WD2500JS (one system has two)
video ASUS Extreme AX300SE/TD
OD LG DVD+-RW GSA4163B
HS Scythe SCNJ-1000 Ninja heatsink
Yesterday the technician informed me that two Neo HE 430 will not boot system properly and he suspected the weak +5v line. After reading this thread, I checked ASUS mb manual and found that P5WD2 Premium needs:
*****
For a fully configured system, we recommend that you use a power supply unit (PSU) that complies with ATX 12 V Specification 2.0 (or later version) and provides a minumum power of 400 W.
*****
I checked other parts of manual and could not find any reference to +5V requirement. It did specify that +8A on +12V_1 and +13A on +12V_2 lead. So if Neo HE 430 is ATX 2.2 complied, it should power up ASUS P5WD2 Premium. BTW these two Neo HE have broken warranty stickers, indicating they might be updated or revised PS.
Today I order two seasonic 430 to replace Neo HE ones.
