Antec TruePower PSU is Suck!

I picked up a 430w Antec TruePower PSU cuz my 431w Enermax's +3,3v rail was stuck on 2,8v. Things were pretty stable with the Enermax but the +3,3v line was still bothering me. (BTW the +5v was around 4,97 - 5; +12v was 11,92). Anyways I got me a 430w TruePower to see if the +3,3v rail would increase. Guess what...with the Antec the +3,3 was also at 2,8, the +5 was at 4,89 (started off lower but eventually settled at that), and the +12 was at 11,61 - 11,67). I was pretty pissed but I gave it till overnight to see if anything would change but nada, zilch. It was still the same. Not to mention that my system became unstable with quite a few page faults. So, I decided to give it to my brother who's system is only a P3 800Mhz. Mine is a P4 2,4Ghz BTW. After putting it in my bro's system the voltages were 3,36, 4,97, 11,92. These Antec's are supposed to be made for P4's. But it makes you wonder what computers they actually tested these on. Low and behold when I put back the Enermax in my system the +3,3v rail actually went up to 2,9 - 2,91. I think Antec should rename their TruePower line to FalsePower (with P4's anyways). 'Nuff said.
 
Well, I've had great sucess with my Antec TruePower, in my system. AthlonXP @ 1.6 GHz, and loaded up with several HDs and CD/DVD Drive, my 5V is at 4.97 constantly, and my 12V is at 12.22V

Anyways, if you're feeling upto it, you can pop open the antec and it should two small white plastice screw type things, each corresponding to the 5V and 12V rails. By turning them, I can't remember if its counter or clockwise you will increase each of the rails.

There is no adjustable pots on these PSU because they don't need them: the rails are not shared like in other PSUs. For the voltage thing on the rails, you should put the TruePower in your computer and wait a bit like 2 days. I've heard of some TruePowers that need to have a burn-in period to attain their specified voltages. There was a really good thread on this in the HardForum, you should check it out!

I've read the other forums and that burn in time is a pile of doodoo. If their PSU's require a burn in period, they should put that on the box. Anyways, I'm not gonna sacrifice system stability just to see if the Antec PSU reaches acceptable rail voltages. If it does at all.

Sounds like whatever metric you're using to determine these voltages is at fault. Motherboard sensors can be off far more than your power supply tolerance specification!

Cheers!
 
Why don't you return the Antec and exchange it for another sample? It may be that your sample is off spec but that doesn't make the whole Antec TruePower PSU line "suck". There's a lot more people out there that has success with this PSU and unless there's a pattern with low voltages ( as in more feedback) with different mobos and configurations, your statement "Antec TruePower is Suck" has meaning only to you.

My Enermax 431w is at 3.44v for 3.3v and +4.95- 5.0v for +5.0v,the +12v is 12.10 -12.22v on mine,never had any problems with Enermax,I believe there`s a 5% margin.

As for your Antec TruePower I would of exchanged if for another new Antec PSU.
 
Well, mine is certainly not an isolated case. There are a bunch of people on other forums experiencing the same problem. I guess Antec's quality control isn't up to snuff. Anyways this is not the first Antec PSU I had to dump. I had a PP303X and the thing wouldn't even let me overclock my Tbird 1.33 to 1.4. Which is what, only 67 Mhz more. What a POS. Let me just say I will be sticking with Enermax PSU's from now on. Another thing with the TruePower is that even though the air coming out from the PSU got fairly warm the fan's RPMs didn't change (stayed at around 1400). No wonder it's so quiet. The PSU must need to catch fire before the fan's RPMs increases. Other people from other forums have experienced this also.

Well I'm using a pop3x right now to power my athlon 1900+, dose a damn good job with a 7volt moded fan. I did have a True Power die on my, but I find that voltages vary from motherboard to motherboad.
 
My 303x lasted me through several PC's. It powered a PIII-S @ 1.5 GHz system most recently. I got the True330 for my 1.6A @ 2.4 cause I needed the extra 12V plug that the 303 didnt have. It and the 2nd P4 @ 2.4 GHz both work perfectly with the True330. The thermal controlled fans are silent! Great power supplies!
 
I've got a pp413 which is rock solid for me. 1.6 @ 2.4 no problem. I haven't tried one of those Truepowers yet.
 


You are just unfortunate to get one of those lower quaility batch. Out of the thousands of PSUs that Antec made, there has got to be at least 1 that went bad.

It's just like saying "Lite-On 40/12/48 is suck"...... you will get a lot of flames cuz most people are very satisfied with theirs.
 
Of course they're silent cuz they're bairly spinning.

Thats the point. Thermal controlled variable speed. Very nice feature. Also has connections for up to 3 case fans that are also speed controlled by the PS. I just built a P4 @ 2.4 PC for a friend. The loudest fan is the Radeon (original 64 DDR) video card! Much better than a so-called "whisper quiet" PS that is anything but.
 
Like I said the PSU must have to catch fire before the fan will spin up. The temperature trigger is set too high for my tastes. From my experience anyways, Antec PSU's have left a bad taste in my mouth. I do like their cases however.

drama major are we 😉

sounds like my mom ...

 
You also could have called us (still can 1-888-542-6832), and we would have replaced the unit for you with one from the 2nd production run.

We weren't expecting the burn-in issue since every one we had tried out here was in spec out of the box. Apparently (and I admit I have not been given much details on this) on some units there was a problem, and the factory has since determined what it was and has corrected this. The problem is not on every unit on the first production run, nor even most. As I've stated on several other forums if it's a problem call us and we'll get it replaced.

Also when you're testing the voltages try to use a multimeter we're finding that even BIOS readings are off (we've had some returned units, but it on our load test machine and no problems).
