Thanks for the link.

 

I am concerned with the internal power cabling upgrade:

1. DC input about 5-10cm
2. 24pin ATX about 20-30cm
3. CPU EPS approx. 40-50cm

 

 

Are there alternatives for that?

This thread is for the 200w version. If you're asking about the 400w version,  this isn't the right thread.

‘Email him directly. His email address is in the website at the bottom. He is pretty good at responding and identifying correct cable

 

Thank you for the nice tip. I have sent an e-mail. I'm curious.😊

I have described my problem to Ghent (email: [email protected]). We quickly reached a deal.

 

HDPLEX 200W Linear Power Supply
On the left are the old cables, on the right the new ones:
2 x DC42 (B) --- XLR (female) to DC (7x5.0) Canare 4S6 cable (JSSG360) => 5V / 2A will go to JCAT USB / NET FEMTO cards
1 x XLR (Female) to Oyaide DC-2. 1G Neotech 7N 16AWG copper => 19V / 10A power supply for my AudioPC

 

HDPLEX 400W HiFi DC-ATX
The old cables have been replaced by much higher quality:
A. DC input --- 7. 4.5. 0 Female to Molex-6P with Neotech 7N 18awg wire
B. 24P-24P ATX --- Neotech 7N 18awg wires with Black sleeve
C. 8P-8P CPU EPS --- Neotech 7N 18awg wires with Black sleeve

Very good quality. Everything works.

Can you show us how you get the power into the case?

 

I am not sure that I have understood your question correctly. Maybe more pictures will help. 😉

SF, ich werde ein paar Kabel für diese PS machen müssen. Können Sie mir bitte die Kabel- / Pinbelegung der XLR-Anschlüsse mitteilen?
 

Vielen Dank

After the combi 

HDPLEX 200W Linear Power Supply (LPS) Black

HDPLEX 400W HiFi DC-ATX 

works for two months trouble-free, I would like to give a small update.

 

For those who would like to use it with a CPU Intel Core i9-9900K, 3,6GHz - 5,0GHz OctaCore could my solution be interesting. The CPU is specified with 95 W TDP. With overclocking the CPU gets over 200 W and could burn the HDPLEX! 

 

Since I need at least 4.0 GHz Clocking for the compute-intensive EC modulators of HQPlayer. So I am already in overclocking. However, my CPU consumes on average only about 35 W at 4.2 GHz on all 8 (virtual 16) cores. The secret lies in the BIOS setting. I adaptively limit the voltage to a maximum of 1.050 V. The system is very stable.

 

 

Incidentally, I find the processing first-class. The high-quality ELNA capacitors are used. You can also see the oversized heat sink.

This specification was too much for my HDPLEX 200W.

I think that those of us whose rectifier went up in smoke were using the 19V rail of the 200W LPS to power a 400W DC-ATX.  The DC-ATX in turn was powering the 24-pin and 8-pin EPS12V of a motherboard populated with a 91W TDP i7-6700K.  Clearly, this is too much to demand of the 200W LPS unless BIOS tuning is used to reduce power requirements.

 

That's probably what happened to me. The good news is that my PC and the JCAT USB and NET cards have not been damaged.

 

The bad news is that the HDPLEX's protection did not trigger! What would have happened if I had not cut off the power immediately? I reported the damage and I'm waiting for the reaction.

 

Regardless, I have to worry about my future specification. An alternative would be the purchase of a Paul Hynes Design SR7 (19V / 10A continuous, 40A transient) which seems to have more margin of stability. When I look at the long delivery times and think about Brexit, I lose the desire. 😂

 

Now I throttled my audio PC and run it on the Keces P8 (19V / 4A), which does a very good job for more a year. The good thing about the Keces P8 is the Over Temperature Protection (OTP)!

 

So I decided to buy another Keces P8 with single output (19V / 8A) and

Over Voltage Protection 19.5V
Over Current Protection 8.2A
Over Temperature Protection 80 ℃.

 

I will use my Audio PC with reduced power in the future. Safety is important.

What exactly happened?  Did your rectifier go up in smoke?  What were you doing on your system immediately before this incident?

My audio PC has been playing music for a few hours. Without concrete reason the PC went out. After a few seconds I saw smoke from the HDPLEX 200W and it smelt metallic. I immediately pulled the plug.

From your picture, it looks like you have a 200W LPS from the latest batch.  When did you get this unit?  HDPLEX told me that on the latest batch they lowered the trigger point for the 19V rail from 15A to 12A and made the heatsink bigger.  

Yes it is the newest batch. After the very hot device cooled, I removed the top plate to check the fuse. The fuse was unharmed. When I turned the power back on it smoked under the big heat sink, where the rectifiers are located.

 What software are you using to monitor power draw (your reported 35W)?

I use the Asus AI Suite III on Windows 10 Pro. In the picture above is the bottom left display: 100.0 x 42 (32.8 watts). Presumably, the ad is not very accurate. In Keces P8 I see the actual load in Amper. 

 

It is a pity that the HDPLEX 200W is obviously not very stable. On the other hand, I demanded the power supply very much. The HDPLEX 400W HiFi DC-ATX is undamaged and does a very good job. It works perfectly with the Keces P8.

I have just received a return label. HDPLEX reacts fast. I will keep you up to date. 😉

Die schlechte Nachricht ist, dass der HDPLEX-Schutz nicht ausgelöst hat! Was wäre passiert, wenn ich den Strom nicht sofort abgeschaltet hätte? Ich habe den Schaden gemeldet und warte auf die Reaktion.

 

Unfortunately I still don't have my HDPLEX 200W Linear Power Supply (LPS) back. HDPLEX support tries very hard, but there are big problems in availability:

It has been shipped back to my engineer one week ago and is still pending custom clearance in China.
I will try my best to ship back the repaired unit.
If I have stock in DE, I would have shipped a new one instead.

I have sent it back to my engineer but they has been hold in China Custom ever since.
Let me check if my engineer can build another 200W from spare parts.

 

 

After all, it didn't stop me from buying an HDPLEX 800W DC-ATX (I checked availability beforehand). 😅

 

This is now powered by two Keces P8 19V/8A, in sum 19V/16A. A very good combination.

[StreamFidelity]

Strange but true! My HDPLEX 200W LPS is repaired back after 4 month. 👍

 

It works fine, but I use Keces. If anyone is interested please PM.

Since now you have the HDPLEX 800W DC-ATX does it gives you better sound quality than HDPLEX 400W DC-ATX ?

 

I have to answer this question in two steps. 😉

 

Step 1
For me it matters a lot whether I run the 400W or 800W DC / ATX converter. 800W means more calm and more power for my upsampling. I convert everything with the HQPlayer to DSD 256 with the high-precision and very computation-intensive EC modulator (ASDM7EC). The difference for low power systems may not be that big.

 

Step 2
I found that the direct power supply to the CPU and a larger motherboard brought even more SQ. In this case, the 400W DC / ATX only supplies the mainboard. 800W DC / ATX is to big in the chassis.
