Problems with Antec PSU's & Neo2 Plat!!
***************NEW UPDATED INFO***************
Seems that Antec's (even brand new ones apparently, boo me) still have potential issues with the MSI K8N Neo2 Platinum! It has been rumored that this is due to incompatible startup timings between the PSU and mb here: linky
It does not and will not happen to everyone! It is unknown whether it is a batch of Neo2's or what, but the potential for a dead PSU or motherboard is there! It doesn't even seen to happen right away, mine lasted 7 wonderful bug-free days before it refused to boot or spin the fans for more than 2 seconds -- testing found my PSU was functioning 100% fine! My motherboard, however, will have to be RMA'd as it shows the same symptoms no matter what PSU is used now.
Most of the problems seem to be this: customer buys MSI Neo2 Plat board, sets up the new components (Antec PSU powering) and after a day or two the system will fail to make an effort to turn on. They then either RMA it, or can force it to work a couple more days by completely disconnecting the PSU, taking the battery out, and shorting the battery connection. When they get a different brand of PSU the board works fine: edit - if they were lucky and the PSU or motherboard did not damage each other from this bug!
Following taken from Tweaktown. It describes the problem that Abit AV8's were having with the Antec PSU's, and it seems they have been able to remedy it.
10-13-04 Update: As I mentioned before, I have been in contact with Antec and have received a confirmation for the ABIT brand motherboard. Below is a blurb from their company representative on this issue:
We've heard of problems with our TruePower's and Abit's AV8 motherboard.
Recently Abit reported that our True power series has compatibility issue with their AV8. The symptom is the system will be in reboot loop during startup. We've tested all Truepower models here and haven't been able to recreate the problem.
According to our engineers, the symptom is not happening to every unit, but rather to a few here and there. They have found out that the instability was caused by 5Vsb and they come up with a solution by changing a capacitor in the power supply.
As a service to our customers we're replacing problem TruePowers with these updated versions. We instituted an inline change for all TruePower power supplies so that in the near future exchanging the PSU's with us will not be necessary.

This is due to the fact that earlier Antec models were not designed according to Athlon 64 specifications. Furthermore, they were vary much castrated in terms of power, which made it very difficult to them to keep up with newer Prescott and K8 systems. Let's take my Antec TP 550W as an example. My first 550W, purchased in January, came with 24A on the +12 volt. Over the summer, I RMA'd my unit and recieved a brand-new 550W, which came with 30A on the +12 volt. So you can just imagine how some of their lesser models have been castrated in the same manner. I have no personal issues with Antec as a whole, but currently I do not feel comfortable in recommending their units to the Athlon 64 enthusiast. And if you already own a low-to-midrange equivalent, NOW is a very good time to consider an upgrade.
For whatever reason Antec made all of its Truepower, TrueBlue, and I think TrueControl with pretty weak amps on the 12v rail when compared to other top PSU brands. The newest models all have +6A higher max over what was previously on the 12v rail, as you can see by deception`'s 550W story. If you have one of these older versions (see Antec's site for current specs) then you may experience problems powering any new A64 system because of said weak 12v rail!
