I see some mention of the A4 version of the Neo 430 watt. Has Antec officially announced they have one? I was using the truepower 2.0 550 watt power supply, isn't that a pretty good one?

The truepower is good, but the neo he is quieter, more efficient, and has modular cables. Check out the reviews - they've both been tested here (tp 2.0 430w). Based on what I remember of the tests, I'd take a chance on the A4 rev., but if you're happy with the truepower, go with it.

It is quiet, and I do like the modular cables. So Antec has officially announced an A4 version?
Thanks

Bought a P150 last week. When I opened it during the weekend I saw a mark "2005-11-XX" on the chassi and no revision note on the serial # sticker on the PSU.

So, I got an old one and will likely end up with problems when the rest of the components arrives?

There's absolutely no way to tell until you assemble your components and run it.

I also bought a P150 a few days ago. The serial number on the power supply is 0511... and the warranty sticker is broken.

I've had no issues with it, maybe due to the amount of hardware I have attached.

ABIT AT8, AMD x2 3800+, Big Typhoon, 3x Samsung SP2504C, XFX 7600GS, TriCool 120mm & Nexus 92mm fans.

Add the Asus A8R32-MVP to the list of motherboards incompatible with a Rev.1 Antec NeoHE 500

System Specs:

Case: Antec P180
PSU: Antec NeoHE 500 (Soon to be replaced by a 620w Enermax Liberty. You'll see why 620w in a second)
Mobo: Asus A8R32-MVP
CPU: Opteron 170 @2.6 GHz
RAM: 2Gb Patriot PC3200 @ 431MHz 3-3-3-6
Video: Sapphire x1900xtx (adding CF card soon)
HDD: Samsung P120 160Gb
Optical: NEC 3540A, Memorex 48Maxx
Additional: Creative X-Fi Xtreme Music, 56k modem
Fans: 2x Med. Scythe S-Flex, 1x Nexus Real Silent

Water cooled and really quiet, although I'll probably replace the Liberty fan with an S-Flex.

Today, 3 April, I finally received a replacement NeoHE 430 - about a week after posting off the old one with its RMA number to Rotterdam (and just over 4 months from when I entered my first RMA request ticket on the Antec site).

I plugged it in to the same setup which lately caused problems (ECS 760GX-M motherboard, AMD 3100+, etc) and so far it's working.

The strange thing is that the new PSU I received - which came in a full retail package - was labelled not A2, A3 or A4, but A2.2:

Absolutely no connection whatsoever to the mangled sticker and a fixed neo.. I received one of the first if not the first 150's from newegg and it came with a mangled sticker.. we are talking last FALL. I think every neo has a mangled/broken sticker. In my case(s) it was not a load issue that kept them from working... I tried barebones setup, fully loaded, you name it.

So, is there a A4 version of the Neo 430 watt power supply?

Geezerman,

Yes there is a Revision A4 but Antec has not announced it nor will they. AFAIK, they won't even change the outside of the NeoHE box. They will simply slip it into the distribution channels and let their customers play the lottery.

allenlux,
Thanks for the info and the picture. If this wasn't so funny I would cry. Antec says they started shipping A3s in 0512, yet you have an A2.2 from 0602. Unfreakingbelievable. My only theory is that "newbuilds" receive the A3 or A4 designation while "refurbs or rebuilds" get the A2.1 or 2.2 designation. I guess as long as it works we should be happy but my patience with Antec is running out fast.

I just had another shutdown with my PC, was working at idle at the time. RMA here I come,,,and it's a A3 model too, made Dec 2005

Has anyone specifically asked antec for an A4 rev? And what was their reply? Has antec been paying shipping? TIA

I have to say, you guys must have the patience of saints. There is no way I could tolerate having to wait 4 months (!!!) to get a fixed PSU. That thing would be in the dustbin quicker than you can say "Defective PSU engineering".

I have quite a collection of computers in various stages of construction and deconstruction, and a generous stock of PSUs, so nothing was exactly held up by not having a working NeoHE. It was a minor irritation, no more.


I had a good look at the packaging. There's no sign that it was anything other than a full retail package.

The good news is that so far my new "A2.2" revision NeoHE is working fine.

For someone with only one home (essential) computer I suspect it would have been a very major irritation indeed. Not everyone has half the stock of Newegg sitting in their back room.

I asked Antec support (Europe) if I can identify my PSU as properly functioning or a potential trouble maker.

The response (after a second try) was:

"The serial number should start with 0512 or higher."

I haven't read anything about this before; is it something they made up to get rid of me or something of interest?

My Neo HE430 serial number starts with S0512, it's a A3, and it's not a good one, at least it's not good working with a Asus A8N-E.
I laughed yesterday when my PC shut down right in the middle of doing my RMA paperwork to Antec....by he way, the head of tech support in California told me there is no A4 version. That could be their policy to say that.

That's interesting as spcr claims to have received A4 revs.

LOL, I guess they want to keep it a secret. You sure you don't want to wait for the A200 version? I hear it's the bomb.

Well, I had good luck in the past with Antec. I'll just sell the Neo, when I get it, and go back to the Truepower 2.0 supply

I have a s/n starting 0512 (A3-rev) NeoHE 430 that have some load issues, it needs much more than stated 1A @ +12V line to power on (if I have calculated right the power on load is more that 3A, as my dummy load uses 1.5A and board + CPU + 2xHDD (SP2504C might have some power on delay) + dvd-rw + cd + floppy do use more than 2A). Also I did ask from MSI if MSI K8NGM2-FID has some power on delay at the +12V line, and they did state that there is no delay circuit on board.

Conclusion: There definitely is still some issue with the s/n starting 0512 (A3-rev) NeoHE 430.

I have asked Antec Europe for an A4 replacement, more or less to see what the response will read.

I just got my p150 case today with the NeoHE. Can someone tell me what are the chances it will screw up with my computer? I am waiting for my MSI K8NGM2-FID to arrive Monday and am worried that it might not work with it. What are the chances? My power supply doesn't have a revision number on it. The serial is S0511xxxxx so I am guessing it is one of the older or even the original models. Anyone with this serial number and motherboard having any troubles, or lack thereof?

If you are using only onboard graphics nor you don't have any power hungry pci cards, like Sound Blaster X-Fi, I would expect problems. I had S0511 that had a power on problem and now S0512 that suffer from it too. Solution is to add some dummy load or better ask Antec to fix the PSU.

Would a 7600gt do? That's probably the only semi-hungry component in my computer to be.

try a hairdryer or toaster oven

I am pritty sure it will be enough.

Got my 2nd P150 on Friday, as I had the usual issues with the first one.

Revision A21, serial number starts with 0512, and it works only if the TriCool fan is connected. If the fan is disconnected, the PSU won't start.
Config: Asus K8N, A64 2800+, Zalman CNPS 7000 AlCu, 512MB Kingmax Hardcore, Radeon 9200, Leadtek Winfast 2000 DV, 4 HDDs, Toshiba SD-M1612, NEC ND-4550A
No random shutdowns yet, but I have to do some stress tests to confirm the stability of the PSU.
