My problem WAS the Antec PSU

I got in my new Rosewill 550W single rail PSU today that has 35A on the 12v rail and I slapped the crappy Antec TruePower II 430W back in it's original box ready to be shipped back. This fixed my problem. The Antec 430W could NOT handle the overclocking of my cpu. When trying to run games or 3dmark05 my system used to just shut down automatically.

I am happy to say that I am back at my 2.75ghz overclock and my ram running a divider at 181.5mhz 1T with 2-2-2-7 timings, using this new Rosewill 550W PSU.

It's so good to be back! Thanks to all that helped especially GuitarDaddy, Zebo, n7, nick1985 and g33k. I really appreciate your patience and time you took to assist me in discovering what the problem was and getting me back up and running. Just goes to show how helpful people on this forum can really be. 🙂

Thanks again guys!

Do you have a link to you rPSU ? I would be interested. I have Antec on every system I have and they are great. Maybe the two series suck though...
 
Well, I am running a X2 4400+ at 2560 with an Antec 380 rock solid. I fail to see why you need a 550. I have another X2 on a Antec 430 at 2530 with a 6800GT. I say bad PSU or something..
 
yeah, i got the 550 only because i was toying with thoughts of sli someday. that psu should have handled it.
 
Well in the manual of my motherboard it says that it requires 18A on the 12v rail, the Antec 430W only has 17A on the 12v and it has dual rails but since my geforce 6600GT doesn't have a power connector then it gets slapped on one of the rails automatically and it just so happened that the rest of my components were using that same rail. So intuitively it overloaded my PSU.
 
Are you trying to imply that a higher single rail rather than two rails helped?

Oops! I have a dual rail Enermax noisetaker 420 watt. (But I don't have anything powerful in my system at the moment.

BTW, I did hear someone saying Antec has gone to s*** lately.

Thats EXACTLY what I'm implying. 🙂
 
Dual rails sucks, antec sucks or is spotty to be kind, I dont care how popular they are, marketing sells stuff is all that proves. I burnt two true 480s to the gound. Overclockers should not use them period, some people just have to learn the hard way I guess. Dual rails is not used by high clockers and talked about negitivly thoughout forums.

Rosewill rocks the house. 35A on 12V line and dead silent low rpm 120mm fan for $55 bucks.


How can you beat that? Cheaper, more powerful, quieter? Sounds like AMD.

Edit, Oh and no problemo Joe.. you were a pleasure to assist.🙂

Thanks Zebo🙂

Hey I got another question for ya.. (as if that wasn't stating the obvious, right?🙂)

This Rosewill 550W PSU is awesome. However it's a little confusing. The fan that's inside hasn't come on yet and I was wondering do some PSU's have a temp monitor in them to where the fan doesn't come on unless they get too hot? I noticed in the back of the PSU along with the power switch, there is another switch with 3 settings. They are labelled L A H ( i THINK this is Low, Auto, High for the fan). It's set on A (Auto) right now. I just wanted to see if you knew if by having this set on Auto, does that mean that the fan won't come on in the PSU unless it gets too hot?

I already send Rosewill an email about this just to give me some piece of mind, but I was wondering if you knew maybe? Or anyone else with a Rosewill PSU knows about this?

Thanks for the input in advance!
Joe
 
I can't comment on the Rosewill specifically, but I've had several Antec with a similiar feature. "Smart Fan" or whatever, where that extra fan is temperature-controlled and will only run when the PS reaches a certain temperature.

The fans on, you just can't hear it since it spins about 300 rpms.. visually inspect.

I did look at it and it's not spinning, but I think it's because its set on Auto instead of Low or High. (There is a switch on the back to set these 3 options)

I think because the PSU isn't getting hot so the fan isn't coming on. I could be wrong though. I'm still waiting for an email reply back from Rosewill.

Hmm sould be spinning...turn fan to high and see what happens..

I'll try that tonight. Another thing I noticed was on my old Antec PSU there was a 3 pin connector coming out of the PSU that connectors to the "Power Fan" connector on my motherboard. However the Rosewill did not have one of those, it had a 24 pin connector, a 12v 4pin connector and all of the 4 pin molex plugs...but I didn't see a cord to plug it in the the "power fan" on the motherboard.

Hmmmm....it's been working fine without the fan being on but this is kinda worrying me a little bit.
 
I've had two Antec power supplies fail. Both had their 5 volt line reduced to about 4.5 volts, which still lets the computer work, but not very well. These weren't overclocked or heavily loaded machines.

Some people feel Antec is great (maybe cause they get such great reviews all the time) and they don't believe me. Well, I wrote a little web page with photos showing the voltage too low. Here's the link:

or got a bad one. a lot of confusion on psus. i have the tpII and the thing is great.

as far as the dual rails, this is how they are divided. i emailed antec to confirm this. this is only the tpII line, i don't know about the others.

heres the 12v under load, or near as loaded as i could think of. specs are in sig.

i also tried the 12v2 reading from the cpu connector under load but its awkward to take a pic of. wouldn't matter as its the same.
 
So far, our work fleet has something like 25 TP330's and 10-12 SL350's. Some are one year old, some are two years old, some are going on 3. Statistically-meaningful sample here 🙂

One failure so far, an SL350 that decided it wasn't going to start anymore. Considering the number of machine-hours on our fleet, that seems plausible. It's under warranty, I'll just have to stop being lazy and call it in.

Anyway, I like my TP2 480 fine so far, but I'm aware of the potential gotchas of dual-rail (thank you SO much, Intel) and would've gotten a 550 if they'd been in stock. Hmmm, someone needs to make a "rail-merger" adapter to merge dual rails back into single... :evil: DISCLAIMER: I don't know what will happen if you try, don't blame me if you blow stuff up! 😛

joejccva, the Antec's 3-pin fan wire sends the RPM signal of the fan to the motherboard, but doesn't power the fan. Your PSU should power its own fan.

edit: that's an interesting link, rise4130. If that's correct, then plugging in the 24-pin main and ATX12V secondary apparently gives the mobo (and attached stuff including PCIe video cards) access to both 12V rails on a TP2.
 
I killed two Antec TruePower 430's with my overclocked Barton and FX5900 and 9800 Pro. 5V rails died on both of them... one was down to 4.2 volts during POST.

In that photo, the PC was running at about 80 watts, according to the little power meter on the coolermaster PSU that replaced it. With the original video card reinstalled and USB devices reconnected, the power rose to about 100 watts.

I'd expect an Antec "true" 380 watt PSU could deliver 80 or even 100 watts!

Yes, it really was a "normal" PC. One Athalon 2600 CPU, 1 disk drive, 2 cdrom, 1 floppy, gforce4 video, small handful of USB devices. Only one part was unusual: a defective PSU. After the coolermaster replacement was installed, the system has run reliably since. It's still early to know if coolermaster will prove to be reliable in the long run. But Antec has let me down. TWICE.

 
Well I have 2 X2 4400+'s OC'ed to 2560 BOTH on Antec 380 true power, and no problems, one even has a 6800GT in it ! You don't need 500-600 watt power supplies for even an X2 overclock. Actually I sold one of the 4400+'s to Duvie yesterday, but is was running 2xF@H solid for over 2 weeks, no problem even at 2560 ! I also have an Antec PSU on every of the the 9 PC's current;y running in my house , and have for months 24/7 running F@H. Also just got done with a lan party at my house for 8 kids, 18 hours gaming non-stop. (time for some sleep)
 
Well I just wish that ppl would stop Generalizing their anecdotes.

Ive seen this often over at DFI-Street The Antecs have a high rate of failiour. And the Requirement for the LP MoBos are 480W name brand ATX2.0 or better. Now there are anecdotes of ppl that overclock ther DFI-LP nF4 with a 6800 GT or U) and a couple of HDDs and some other stuff on a 350W old 20 pin PSU. The thing is that just bc 1 person has managed that it DOES NOT mean that its going to succeed for everyone. Acctually I bet U that if we tried to do it a hundred times it would fail 99 of them.

So please refrain from giving GENERAL advice based on your 1 system bc it will probably just cost ppl money.

Now @ mechBgon
Well Antec used to be very good and I have some old ones as well (but not that amount) and there has been more failiours last yr then previously (IMHO totally u scientifically). However they seem to have gotten a little better lately. I guess they had QC issues but i dont know.
