Just bought 2 new SG31G2s in from our regular supplier, and Shuttle seem to have moved from ElanPower supplies
to "ENG" ones.  These things make fizzing noises (both machines) like arcing electricity when powered up.

Has anyone else seen this?  I'm scared to ship to customers in this state because arcing noises sound bad (thinking
health-and-safety here!).

Of course, it could just be bad luck, but to have two units both with the same problem....

Gotta say I'm rather un-nerved, because after years of doing hundreds of shuttles, I've never had this kind of
thing before, and the SG31G2 has been such a good workhorse chassis for people I'm pretty shocked.  (Pardon
the pun).

Anyone... any thoughts, info?  I *really* don't want to have to start buying in PC40s for every system!

Arching fizzing noises could be some bad/faulty capacitors....an thats generally not a good sign.

Shuttle europe have offered to RMA-swap the XPCs for elanpower versions, which is a help.  My bigger concern is
long-term...  has anyone had a positive experience with the ENG supply?

has anyone had a positive experience with shuttle Smiley kidding Tongue

this is the first thread i've seen detailing this possible issue, so fingers crossed, would be a bummer if shuttle moved over to some crappier psu's to save money or something. noise aside, the psu is the one part of the shuttle barebone that has generally always gotten the thumbs up, don't go ruining that reputation shuttle!

Well, Shuttle Europe have been brilliant (which they usually are... so often companies wallow in mediocrity) so kudos to them again!  They let me RMA just the supplies, and are going to replace them with ElanPower units.  Guess we'll just have to wait and see on the next batch of SG31s!

In the meantime, if anyone has an ENG supply in their Shuttle, feedback would be great.

I purchased a SG31G2S for a replacement of my old SB61G2V4. The Shuttle came with that dreaded ENG power supply. That thing is awful. It makes a very high pitched buzzing sound. I think they use some kind of cheap fan in it. It's very loud and annoying. The fan is at the front of the power supply instead of the back.



I have a SD30G2 Plus with a ElanPower PSU and I swapped that out with the ENG one. Guess I can try to fan mod the ENG PSU, but I haven no idea how to even get it opened.



Anyways, here's some pictures. I hope the current G2 Shuttles aren't using this awful, awful power supply.
