Thanks. I agree that it is really strange that the PSU turns on from S5 but not S3. However, I think the board does all it can, by pulling PS_ON# to ground. This is exactly what it is supposed to do and in S5 it works; yet in S3 it doesn't.Monkeh16 wrote: I don't see how it can be a software problem, but if the machine boots from S5 it should boot from S3 too. It could easily be the board (DP35DPs are good boards, but.. far from perfect).
Nexus Value 430 PSU: Affordable Silence
Agreed, but I cannot remove the last DIMM module, and I did remove ALL USB devices. Moreover, the voltage on +5VSB is 4.95V, which indicates to me that it's not overloaded, and this voltage does not change at all when I press the power button. The only thing that changes is that PS_ON# goes to 0V immediately. The fan of the PSU does not move at all.Monkeh16 wrote:It's possible it's pulling far too much current from +5VSB when booting from S3 and causing the PSU to shut off.

Thanks for your hint. I did push a wire into the ATX connector's green and black pins and the voltage goes from 3.8 to 0V when I press the power button during S3. So the green wire MUST be making contact with the mainboard, otherwise it would not transition to 0V.NeilBlanchard wrote:Did you test the PSU with a wire in the green pin? Sometimes this "stretches" the contact sleeve enough to keep it from making consistent contact.
I'd be interested to hear from other users (or SPCR) if they had any issues with S3.

zhell,
Just to let you know, I bought a Nexus Value 430 for another computer I built and have no problems with it. It boots fine and goes into and out of S3 sleep mode without problem. I don't have any of your measuring tools, but the voltage number I get from HWMonitor are:
ATX +3.3V = 3.33V
ATX +5V = 5.00V
ATX +12V = 12.06V

Thanks Dave, good to know, I appreciate your feedback.
Nexus let me know they also have a PSU waking up just fine in a test machine. I think it is some incompatibility between my machine and the PSU.
If I get around to do it, I'll try and take some current measurements to see if any component is drawing too much power during S3.

Nexus seems to have new 530W version of this PSU, Nexus NX-5000 R3. Preorder price is similar to 430 value here in Finland.

Can we expect SPCR review of this unit?

Have you also reported the problem to Intel?
Reading over the Release Notes for the latest BIOS 0572 I see that they have fixed various issues relating to S3 in this and previous BIOS releases, so it's certainly possible there are more issues not yet addressed.
I have an Intel DP43TF, and resume from S5 didn't work for me with the original BIOS that came on the board, but an update fixed the issue.

Hello!
I bought this Nexus VALUE 430, but am afraid I have a bad unit. Voltages are fine, system boots up perfectly and gets in and out of S3 without hassle. What is making me skeptical is that a kind of "burnt electronics" scent comes out of the PSU. I've had the Nexus only three days now, and this scent is quite strong. Is this normal? Do all PSUs have this and should I be worried?
Thanks!

BIOS might be part of the issue, I have tried several, including the latest versions and it made no difference at all.confusion wrote:Have you also reported the problem to Intel?

It does not even begin to resume. And if I put the machine into S3, then short circuit PS_ON# to GND, it does not turn on either.Monkeh16 wrote:During S3, but what about the draw when resuming?zhell wrote:I have measured the current during S3: It is 1.1A, hence well within the specified 2.5A of the PSU.Monkeh16 wrote:It's possible it's pulling far too much current from +5VSB when booting from S3 and causing the PSU to shut off.
Even if I put the machine into S3, then short circuit PS_ON# to GND, then completely disconnect the PSU (while keeping PS_ON# connected to GND), the PSU does not turn on either. Only when I then briefly release PS_ON#, then pull it back down, it turns on.
This leads me to conclude that the PSU detects some problem during S3 and decides not to turn on any more -- n no matter if the problem persists or not.
I just received my Nexus Value. It's a clear improvement over my older Antec EW with scythe fan mod, but I can still hear it from one meter distance. I would say that the noise character is nice unless you put your ear right next to the psu. I don't currently have anything in my computer that could stress the power supply, but if it won't ramp up considerably under 200W load, I'm happy. This might not be the right choice for extreme silencers, but if you have even single fan running in your computer, going with passive unit won't be worth it.
Edit: Is the fan supposed to make a ticking sound?

Nice improvement from the Earthwatts 380 in my NSK3480 but... the fan ticks too, when the other fans are regulated at min speed with Speedfan (2x92 Yate loons + 1 Noctua), I can definitely hear it ticking from 1 meter.
It is not strong, but silence fanatics like us would notice it

Mine clicks too! The Scythe 12mm fan I have on my ninja CPU
cooler also clicks.
Anyone tried replacing the 430 PS's fan? With which fan?

Nexus Value 430 tested on 240V/50Hz
just got one to replace my aging Enermax EG365P-VE (at least 6 years old) fanmodded to a single Panaflo FBA08A for my P4 2.8GHz.
when CPU is stressed (134W) and GPU is maxed out (156W), power draw is 9-11W below what it used to be, which corresponds to an increase in efficiency from 78.5% to 84% if I've properly interpreted the figures provided in the review. Seems like the old Enermax PSU wasn't that bad in the first place.
However, the Value 430 is much quieter than the Panaflo at low speed in the Enermax, and the Enermax will be a nice upgrade for my HTPC as it's much quieter than the PSU in there.

I was told by one of the guys that works at PC Case Gear in Melbourne (my usual source for quiet PC parts) that the Nexus Value 430 has not received electrical safety certification in Australia, which is why they don't stock it.j386 wrote:Desperately trying to source one of these in Australia. Has anybody had any luck importing them at a reasonable cost? I'd even happily settle for a used one.
If the Nexus PSU hasn't been certified in Australia, I would be a little wary about importing one and using it here.
Depending on your budget, you might want to consider the Seasonic X-series PSUs. The Seasonic X-650 seems to be hovering around $200-$210 at the moment. The lower power X-Series PSUs can be pre-ordered now: the X-400 Fanless PSU is $180 at PC Case Gear at the moment and the X-460 Fanless PSU is $200.
Finding some of the other Editor's Choice PSU's on the Recommended PSU list can be a little hard, but some of the other recommended PSUs shouldn't be too hard to locate.

That's interesting, I wonder on what grounds it failed? Maybe they just haven't had it tested for Australian sale at all?
JamieG wrote:the X-400 Fanless PSU is $180 at PC Case Gear
I was looking at the X-400 but wasn't really planning on getting a fanless model. Also, the price is a bit too far out of my budget (~$100). My next choice was probably (even though many people apparently don't like the brand) the Cooler Master Silent Pro M500, but I can't seem to source them in Australia either (only their 600w/$129 brothers).
The SeaSonic M12II 520W is looking pretty good, although I'm a little concerned about the noise levels. Also, I can't seem to find an efficiency graph for this PSU. Can anybody vouch for this particular model or know how it compares to other SeaSonic models?
Thanks heaps for your time!

Don't worry about noise - up to 300W the fan is inaudible (personal experience)j386 wrote:

See here and another glowing review can be found on jonnyguru.com
Personally, I think that at it's price point you won't get anything better.

Correct, we do not have a distribution in Australia for the PSU's so until now we haven't had them tested for Australia.j386 wrote:JamieG wrote:that the Nexus Value 430 has not received electrical safety certification in Australia

Until now? So now they have been tested? What was the outcome?
