Re: Supermicro PWS-0060 *failure*, please advise
i have seen a few liteon units with very poor soldering.
fixed a neighbors liteon and when i pulled the pcb i commented it looked like a 2 year old with a cold iron and plumbing solder had built it.
he commented that it looked like a mud dauber had been working on it.
had one in a hp that had missing +3.3
bad solder joints and crap caps.
stay tuned for a ablecom dissapointment i got in last week.looks like a deer board inside!Comment

Wow man...doesn't look like the insides of my unit?
The winding on the toroidal inductor, in the last picture is just garbage. Who-ever winded that coil should be shot.

Re: Supermicro PWS-0060 *failure*, please advise
If the +3.3V O/P is mag-amp regulated, it sounds like the transistor driving the mag-amp inductor is either shorted or turned full on by whatever is driving it.PeteS in CA

Re: Supermicro PWS-0060 *failure*, please advise
Both the 3.3v and 5v have sense wires running back from the EPS connector to the PCB - can we assume that both be mag-amp regulated, or is something else at play here?Originally posted by PeteS in CAComment

Re: Supermicro PWS-0060 *failure*, please advise
T, I don't have specific knowledge of this P/S, but unless it's a fairly high-end supply, I'm assuming it has a single main regulator, usually sensing the +5V and +12V. The other O/Ps are post-regulated - the -5V (if it has it) and -12V by 3-T regulators and the +3.3V by a mag-amp regulator.
Winding toroidal inductor with multiple windings with different numbers of turns and different wire gauges is seldom neat; making 10s of thousands of inductors a month is no mean task, either.The winding on the toroidal inductor, in the last picture is just garbage.

Re: Supermicro PWS-0060 *failure*, please advise
Thanks Pete for your advice... I'll be taking a look at it more closely now - componentwise it really seems *very* solid, I'm expecting a poor solder joint somewhere or other soldering-related issue as KC8 warned.
The inductors on my unit aren't badly wound at all, in fact. It's probably luck of the draw, as you said.Originally posted by PeteSinCAComment

No comment on the inductor windings since I've seen a lot worse on a lot more expensive units.

Guys, this is my first server unit. Any ideas on why there is no power switch? I'm still a bit bummed by this.

It can be annoying, yes. I had a separate switch on my surge suppressor for the socket to which I connected it so it wasn't really a problem. Perhaps you could do the same?
A question: does your 0056 model also have the fan running (at low speed) all the time, even when it's only providing 5Vsb?Comment

Re: Supermicro PWS-0060 *failure*, please advise
I can answer that: Yes. The fan runs all of the time. Fire up the PC and it spins full RPM for about two seconds and then comes down to a bout 75% RPM.Originally posted by tiresiasHehe... because servers shouldn't be turned off?

Re: Supermicro PWS-0060 *failure*, please advise
Roger that. Exactly as Jonny said. It is whisper quiet, when compared to my x1800xl's scramjet HSF. That thing (x1800xl) is so loud at start up that I could hear it outside my lab.
Jonny, do you think I would trip something up if I unhook the fans and rewire it so that both fans are being used? This redunantant fan stuff is not my style. If there is a fan I see, it should be spinning. I hate lazy ass fans.

I actually took one of eVGA 7800GTX's out of my machine simply because of noise. I'm eventually going to water cool the other.

Another very very strange thing I noticed. The 12V line dropped to almost 0V for a fraction of a second, when I rebooted the now OC'ed Prescott !!

All left and right refers to looking from rear of TV (or looking from front with TV upside down)- TV came with vertical bars and no image. Found faulty TVS on left buffer board. Also replaced T-Con (may have damaged the original while hot air removing components, board has slight warp) and have full image but few horizontal lines on the screen. Some of the lines appears to be 2 pixel tall while others are 1 pixel tall.
- Disconnecting left and right buffer board potentially reveals problems on both sides with different signals (unless this T-Con require jumper like Samsung FB_TRDY1&3) Fault

I've got a control display for a Carrier chiller that I'm trying to understand what the common failure with these boards are. This is the board in question https://www.supplyhouse.com/Carrier-...arquee-Display all of them seem to develop a failure with the up and down arrow buttons on the right side of the display, the esc and enter keys I've never seen fail. Once these boards are plugged in they run 24/7, you used to have to press extremely hard with the end of the blunt screwdriver and you could still get the arrows to work but now it has completely stopped working.

Yes, I know I don't post this stuff much anymore....the only reason I'm posting this one is because of a NVMe adapter incompatibility; seems rather planned by Supermicro.....or I'm atleast a bit suspicious. It's plenty new enough to have a UEFI bios but a short 'happy list' of NVMe controllers that will work with this board, as if by some 'miracle', all Intel....so lets start at the beginning; we'll get back to this later.
Of course the motherboard is as the thread title states; X10dai....but we'lre going to have some fun shoehorning this into a modern 'gamer case' that can actually...
