Not yet :(.

I asked the Taiko team to sneak those in to my DIY chassis package. Waiting for the my updated invoice :).

BTW, I paid full price on the chassis... just clarifying if anyone thinks I have any affiliation with Taiko (as it may very well sound like I do from my posts).

May I know the dimensions of the Mundorf 220,000uF capacitor.

Diameter is 90 mm (120 mm with the mounting plate) and almost 100 mm tall. 

Or around 3.5'' diameter and 4'' height.

Can I get in queue for 1 of each item shown above?

I don't think these will go as fast as the first batch of the chassis. Taiko has them in stock as they were planned for other projects that are not going through. Should be listed on their website at some point. I'll post a link when they are listed.

Interested in why there is a lone 22,000uf 40v Mundorf AG there besides the rectifier board.

That's the first capacitor after the rectifier and before the choke. I may try 33,000 uF too. Emile suggested that for the first cap a Mundorf AG might be better and it's worth experimenting. I may try some 1-2 uF film caps too. I have some Duelund tinned copper foils caps laying around. 

 

BTW, I will be using this wire - https://www.partsconnexion.com/MUNDORF-89422.html - I have done quite a few tests with it since I got it in June last year, and it's definitely high up on my list. 

[MarcelNL]

@Nenon Do you happen to know/have the spec sheet for the Taiko rectifier? I wanted to try a single PIO as first cap, but the Saligny needs 4700 uF as first cap to work properly, I reckon the Taiko has a similar requirement, so just checking,

 

I just replaced the Hypex with my alternative softstart, listening for a difference once everything is warmed up again.

 

Edit:  never mind, the difference is already clear!

Hi all, now that I have a Taiko case I'm starting a new DIY Taiko Sage build. Given Taiko is using custom RAM, what low speed, low refresh DIMMs are compatible with the Sage board? 

 

Any 288 pin DDR4 ECC RDIMM/LRDIMM should work. Max frequency supported by that motherboard is 2933Mhz. Frequency is further dictated by the CPU; in the case of the Xeon 4210 it's limited to 2400Mhz. Memory refresh rate can be adjusted in BIOS.

 

Apacer has part # 78.D1GMP.4010B that would work with the Xeon 4210. Note that it is not the wide temp version that is more desirable. Samsung also has a good selection of server memory.

[Dev]

I can't figure out much from the dimension but those who have the Taiko chassis at hand do you think there is enough space to fit ULPS along with another single rail regulated power supply with SJ DC3 level parts and another smallish transformer, say 100va ?

very nice

any price yet ?

Sounds like the Taiko rectifier will go for around 200 Euro. I am told this is a top quality board with a lot of very thick copper, integrated heat sinks into the PCB, 180A MOSFETS, etc. And those things are quite expensive to manufacture. 

 

The 220,000 uF is expected to be around 300 Euro. This is great because it replaces capacitors for nearly double that price, sounds better, and is a space saver! 

 

 

Here is what I am planning to do for the DIY chassis integrated ULPS:

Noratel transformer (250 Euro) --> Taiko rectifier (200 Euro) + 22,000 uF Mundorf AG cap ($50) + Film capacitor (TBD)--> Hammond 159ZJ choke ($35) --> 22,000 uF Mundorf Mlytic HC cap ($140) + VCAP Odam 0.1 uF ($60) --> Hammond 159ZJ choke ($35) --> Mundorf 220,000 uF (300 Euro) + VCAP Odam 0.1 uF ($60).

 

That's not bad, close to $1200 for the main parts. Of course you need other items like wire, IEC inlet, Molex connectors, etc. so probably close to $2K. I highly recommend you try the Mundorf Copper Angelique wire for this. 

 

There seems to be enough space to fit a v3 with Mundorf HC caps this way.

(not the final layout, just a dry fit; also, the Taiko rectifier can be mounted vertically to save more space)

 

If anyone prefers to use an array of Mundorf AG caps like in the Taiko Extreme, I have some high quality boards with 6 Mundorf AG caps and VCAP Odam film cap. See highlighted in red. You can use one or two of these together. 

 

Lastly, as I was checking for parts to see if they fit, I realized I have over a dozen 22,000 uF Mundorf HC caps that I have no use for. Those were bought for my ULPS experiments and I have used some of them with copper bars and so on. If you need one, send me a PM.

@Nenonthanks for all that you do for the DIY community. 

 

I found Mundorf CAW myself and stopped looking for it since it wasn't available anywhere I shop, then you mentioned it and I had to try it. So glad i've re-built the ULPS with this wire. I highly recommend this wire. The break-in is lengthy, and can be a bit sinewave like (wow one day, what the heck the next) but after several weeks i'm incredibly happy with the results. So happy with it that I've picked up 12M of it to play with. 

 

Those cap boards look slick! 

To go dual AG array or Custom 220,000uF cap is the question. Knowing me, I will find a way to try both! 

 

It is beyond exciting to see how the components fit within the Taiko DIY chassis. Bravo. Great update.

[Dem]

Anyone interested, the Mundorf Copper Angelique wire. following my request will be available from Audiophonics at the end of August.

Curious as to where one can find the details regarding the cpu / memory frequency limitations. Do you have a specific reference?

 

Update: Nevermind, I found the information in the Intel CPU Specifications. 🤭

Saligny power!

As you discovered, the spec list will mention the max memory frequency supported by the CPU. Same for motherboards.

 

I also want to clarify my original post. You can run memory at a lower frequency than rated, meaning you can run memory rated at 3200Mhz at 2400/2666/2933Mhz. To that end, Apacer has part # D51.27267S.002 in 16GB capacity, and part # D51.27244S.002 in 8GB capacity that would work with the Intel scalable CPU's. These are the wide temp "industrial" grade memory.

[Downtheline]

4gb 2666mhz wide temp registered ddr4 ram

from Apacer (D51.23184S.001).

 

These are about $84 each from Apacer. As I read it, recommended to get 12, to fill each ram slot on the asus sage mb for the diy cpu build. 

[JJSim]

Yes, for maximum bandwidth it's recommended to fill each DIMM slot, so for the dual socket Asus Sage that's 12 total DIMM's. If you use a CPU that allows for max 2400Mhz memory, you can save cost with the lower frequency DIMM's. The SKU's rated at 3200Mhz are more expensive.

 

Generally Samsung memory is lower priced. Apacer uses Samsung IC's on their memory, so I would expect quality and performance to be on par, though there has been high praise for the Apacer wide temp DIMM's on this forum.

and what is the preliminary verdict?

It appears that it is mounted direct to the chassis without any standoff. Is that correct?

it's how I did it...that is the benefit of the downside of having stiff wiring as Cruyff would say it ;-)

(solid core wire in my case) 

[Rovo]

I did mount the Saligny Power with standoffs (no temperature problems).

Great, that would be the way I’d prefer to do that. Mounting it directly to the chassis will allow greater heat dissipation. I just wasn’t sure if there were any traces on the backside that would prevent that.

Can you share full Pic for your power 
I can see that you are adding vcap and Saligny . can you share the improvement .

 

 

I have same Soul Analogue ULPS ...   but I will try to add  Nenon+Taiko v3  ULPS to my collection  .... I am also thinking if we can add ARC6 modules to our ULPS .

backside is one single aluminum(?) metal surface, not sure if it is grounded or connected so beware before plunking it on the chassis without insulation. Anyway, no heat whatsoever so no need for heatsink-ing either. Standoffs are so 2000's, ;-)

Looking at the specification of the Mundorf Mlytic HC 220000 uF, the lower price and most likely the sound improvement are due to the 40V specification. Perhaps wise with a Toriody transformer 400VA/24V to be a little careful? Voltage at Taiko DC DC-ATX under no load can be something like 36V and a bit. Influence on lifetime?

The main improvement comes from the lower ESR compared to multiple capacitors in parallel. 

I would not be too worried running it at ~36VDC at no load. You can usually push these caps to their rated limit without problems. 

It has been reliably running non-stop for a little over a year now. That's how far back my experience goes with them. Can't really comment beyond that. 

[oneguy]

I am bumping up to the 25VAC secondary Toroidy. 24VAC rectified is 33.9VDC. 25VAC rectified is 35.3VDC. When I lived in Texas my isolation transformer was putting out about 121-123VAC. 123VAC in the primary would be 36.2VDC rectified. 
 

@RovoI would not go higher than a 28VAC secondary (39.6VDC assuming no losses). No real margin for error at the spec. 
 

So the way I see it the trade space is 25-27VAC on the secondary with 40V rated caps. 

[oneguy]

Random Idea for a one case solution with Taiko’s new cap:

 

Mount the transformer in the green circle to the top of the H5 on the inside. Taiko’s new CAPs mounted in the green box on top inside of the case. You’d probably need 20 MM riser for the lid I’d estimate so the transformer clears the MB. If you went with the Toroidy Audio instead of the Audio Supreme you may not even need risers. Thoughts?

 

EDIT: disregard, I forgot about the chokes. No more bright ideas before morning coffee, lol!

[MarcelNL]

you'll also need to put the other two Caps somewhere. The active rectifier nees capacitance to function,

 

[oneguy]

The 22,00 Mundorfs are relatively short. Especially considering raising the lid 20mm or so, so I feel like that wouldn’t be a problem. The 10A chokes however….

 

I’ll keep the idea in my back pocket and do some measurements whenever I have the server open. It would be a nice option for those that don’t want fork over the money for the Taiko case or spend money on another H5 case.
