Running out of 3.3 volts

Tried a memtest in my new box and it freezes instantly.

How much amps do I need on 3.3 volts for 512 GB of RAM, 8 M.2 SSD with 1 TB and a Serverboard with two CPUs and 16 RAM-Slots?

The strongest TFX I've found offer 22 amps on 3.3 volts, but that is 72 watts and from what I've read 8 GB RAM take 3 watts. So the required power consumption on 3.3 V is 512/8*3=192 watts for RAM and 8*5=40 watts for M.2 SSD. Thats 230 watts for RAM and SSD??

Hello matthias_r, 


Thank you for joining the community. I understand that you are looking for power supply recommendations on your server board, let's get this resolved as soon as possible.

  • To understand the system that you have and provide the best recommendations, please provide a detailed description of the make and model of your server system / Enviroment, is it an Intel® Data Center Block?
  • What troubleshooting steps have you performed so far, in regards to the MemTest freezing issues?

 I will be waiting for your response, in case we do not hear from you, we are going to follow-up on this case on 09/14th if you have any response prior to this email feel free to contact us back.

No, it's not a Intel System (are there any 19 " half depth Intel boxes which do not sound like a starting jetengine and can be placed in a livingspace?) and it is not running at its limits...

* Supermicro X9DRi-F (?? watts at ?? volts)

* 2 x Xenon E5-2650L v2 (140 watts at 12 volts)

* 2 x SSD (Kingston A400 240 GB, Patriot Burst 240 GB) (10 watts at 5 volts)

* 2 x 1 TB M.2 SSD (10 watts at 3.3 volts)

* 4 x Logilink PC0086 (2 x SATA to 2 x M.2 SATA) (4 watts at 3.3 volts)

* 8 x 16 GB Samsung RAM (48 watts at 3.3 volts)

* 1 x Phoenix Power Supply FA TFX 500 watts


I ordered a new power supply.


Am I the only one who have a 19 " wallmonted rack in the house and need some sort of server in it? That is what I actually felt after installing a lindy and cisco small business switch...

Switched the power supply with no success...

Then I've read that there are bugs in MemTest86 and installed an OS which is running without any issues!
