Is it normal for DELL-DA2 to do that "buzzy" sound?

Hi, I wanted to use a circuit form my Node (6pin connector) and use Dell DA2 for powering both GPU and circuit aswell to save some space on my desk (make smaller, custom enclosure) It should work right? Well in the moment when I plugged it in the wall (REMOTE and GND pin already connected) it started making "buzzing" sound... Don't misunderstand me, I expected some low noise since it's completely passive but this is pretty annoying and I'll rather use ITX GPU with SFX power supply to fit it in same form factor that I planned for full size...

Is there chance that if I'll buy another one it'll be completely quiet or this is pretty normal?

Hi, @kegare

I've just purchased a Dell DA-2 myself for powering my ADT-Link R43SG and RX 580. However under load, specifically above 100W, it buzzes very audibly. Not loud, but loud enough to be more annoying than the fan of the ATX PSU. The higher the load, the more it does it, and my GPU pulls 150-170W during gaming, so it's really annoying since I bought this to get a quieter system compared to the old ATX solution I had. Did you resolve this issue or buy another one? I have the one with P/N Y2515, is that the same model you have? 

Looking forward to your reply, if you're still active on here. If anyone else has the same model or issue, let me know too.

Hello, @golden_alchemist

I'm not active here anymore, since nobody helps people with non-standard and/or non-XPS problems here, but thanks to mail notifications I can reply you.

Sadly I didn't resolved this issue, but mine did that sound even under 100W so it was pretty much unusable for me. As you say, sound was more and more loud with more GPU load, so it looks like same issue in my opinion. Model number of mine is same as yours.

Anyway, I wasn't brave enough to try to find another well priced unit on ebay and wait for it so I changed concept a bit: I changed PSU to SFX-L (AkiTio Node which I am using had custom SFX unit) and replaced stock fan with Noctua one. Very basic soldering was needed, but noise is gone. With 200mm GPU I was able to fit it all in DIY 330 x 180 x 70 mm case.

I know that this didn't helped you much (pretty much like whole this forum, where only mainstream laptop-related posts are getting replies lol)... If you'll try to buy another Dell DA-2 just tell mi if it has this deffect too. If you're exhausted of troubleshooting (like me) go for reliable SFX-L with large Watt reserve (for 170W GPU go for 300W, most of PSUs with PCIe connector will have ~350W anyway) so it'll never be near it's limit and heat will not be a problem.

@kegare, people may not be replying to your posts because they dont have any experience with the issue/hardware you are using.

More "mainstream" set ups prob get more replies because more people have them and more people experience the same problems (and work out the solutions).

First of all thanks for taking the time to reply even though you're not active anymore. But you are wrong, your post did in fact help me quite a bit.

The DA-2 seems to be a common power supply used for specifically the ADT-Link R43SG, having a dedicated connector for it, and being shown in several videos on YouTube with some receiving it bundled even. This is why I was hoping to find more people who share the same issue, so there could be common factors to determine as the cause, or to rule out. And here your model comes into play, specifically its model number could be an indicator for the issue - the DA-2 series was apparently produced with a lot of different product numbers, such as these that I could find quickly:

  • ours (Y2515)
  • N112H (currently on sale on eBay for 21€, was used by the user as an egpu PSU for years so I think that one probably is fine, I will contact the seller though, and maybe buy that one)
  • 0M8811 (a big eBay listing with many units for 30€ a piece)
  • MK394 (eBay listing, 25€, 2 available)

Maybe it would be worth asking the community what dell da-2 models they have and if anyone encountered similar problems. It could of course be pure coincidence that both our ones have the issue and coincidentally the same product number. In that case we both just had really bad luck. For that, can you tell me which revision your model is? Could be another indicator. Mine is REV A02.

Anyway, I'll keep you updated if I buy the other one and it works. For me it would be the best option because the custom enclosure that I want to make would have only the one cable coming out beside the m.2 connector, and it would look very clean. An ATX PSU, even with SFX form factor, would require a large cutout, and all the cables from both the 24-pin and CPU power would stick out, or I'd have to put it inside, in which case the overall size would increase.

Your DIY case seems very interesting too, as I'm going for similar measurements - would you mind sharing some pics of it, or describe how you made it? Maybe you could even present it in the custom chassis section. Only if you'd like of course, but I think every post made on here can either serve as inspiration, or help with troubleshooting. That's why I posted my build too, despite having a very rare laptop model.

 

Okay, I'm done now, sorry for the wall of text and thanks again for your answer.

I have an MK394 and I only get the buzzing under heavy load when I connect the DA-2 directly to my eGPU. If I connect it via ADT-Link R3G it doesn't buzz.

Not sure if related, but the only similar buzzing I've heard was when I modded a server PSU and increased its voltage above 12.33V - would some boards, like the R3G, regulate / smooth voltage for the GPU?

Hi again @kegare ,

after complaining to the seller of my DA-2, he proposed to send me a replacement unit in return for paying the shipping for it (although he wasn't very happy, thinking I was complaining about some faint coil whine even though I told him I could hear it from all the way behind my desk lmao), so that's what I did - however I didn't really have time to try it out until today, and it works quietly. The product number is once again Y2515, but this time it's revision A01, instead of A02 (which is my noisy one). Other than that, it's the same model:

@timginter Thanks for your input! It's interesting that your power supply makes a noise when plugged directly, and no noise if plugged in the R3G. If I understand correctly, you had your egpu plugged in the R3G, and the DA-2 directly in the gpu's 8-pin port? I didn't know that works. I don't think the R3G does smoothing. There's just not many components on the whole board let alone big electrolyte capacitors usually used for smoothing.

Anyway, I think for now, it seems like a lucky draw for quiet DA-2's, unless there's some relation to its revision A01. Maybe if we get more data, we can say for certain.

Nice, thanks for the follow-up and photos. Glad the replacement works!

My DA-2 are REV02 so can't check if that was the difference.

 

For laptop+eGPU setup, I had both my GPU and DA-2 plugged into R3G. DA-2 never made any noise that way.

The "noisy" setup with DA-2 plugged in "directly" (through a DA-2 to PCIe cable) to the GPU was without R3G - it was with an ITX motherboard for a DIY laptop/portable PC project.

Not sure an eGPU on R3G will work with DA-2 plugged just into the GPU - R3G may still need some power for the board

Hi,

not sure if this helps, but should you decide to replace, i've just done an R43SG buiild with a a Silverstone 450W Nightjar, which is fanless, Platinum rated and completely silent - https://www.silverstonetek.com/product.php?pid=797&area=en.

regarding the buzzing - if its a low hum then in my experience its circuitry/capacitor discharge which isn't a problem, just annoying and can be a result of age.  a high pitch buzz has imho (again) usually been rooted to a dry solder, poor connection, case short or the like << no i'm not an electrical engineer or anything of the sort but have had to replace my fair share of fried power supplies....... others can perhaps offer opinions on how resiliant the rails in the DA-2 are as I've not even held one in years.

my 2cs and apologies for not being more helpful,

K
