Apart from that our external power supplies do not cost 90 Euros but less than half of that.

thats your reseller price i guess?  So why do i have so many failing power supplys with the multi and fire faces i used and still use? 

How long do theese units have to work to be replaced by the company? isnt this 2 years in germany now or are chinese power supplys excluded from that?

So no other users with issues? So no reason for RME to rise the quality..  However i need a new one soon..because when its my special  fireface itself that kills unguilty power supplys i dont like to run it bus powered any day longer than necessary.

I have had only one power supply go bad out of all the equipment that I have owned over a 20 year period...and yes, that was my FF800.  Cost me $200 USD to repair which is absurd.  So the options were trash the unit or spend the $200 basically they 'had' me.  I would also say just by doing a search on the forum you will find that MANY people whom have experienced a failing power supply with your product.  So yes, you do have an issue with the quality of your power supplies and by your responses you are not to concerned about it.  Which is a shame because you do have a good product and reputation - sad you are willing to sacrifice that reputation with such a simple solution.  Because, for me personally, the next time I go to buy a recording interface I will think more than twice before I buy RME again.

Ahhh yes that does make a difference and I see the point.  Yet, even with that case the 800's do still have an issue which sounds like it is much worse considering the cost involved.  Thanks.

Contact Synthax Germany and I am sure they will replace the power supply. BTW, it's warranty, not 'garanty'.

thanks

I understand the sentiment, but I do not understand that an audio professional has no spare power-supply around for recording (preferably several at different voltages or a universal one that can be switched).

No one forces you to use the original RME power-supply and frankly I have no idea where you paid 90 Euro if you'd choose to buy one. Typing "RME Netzteil" into any price search website (or even G++gl+ returns the same 39 EUR everywhere. Seems like your local supplier ripped you off.

Also you should consider it part of your job as audio professional to know about power-supplies, voltages and amperage. When you are playing guitar you usually even know about negative and positive tip. And the RME devices make this even so much easier as they accept a wide range of voltages, both AC or DC and thus don't care about tip polarity. Cannot get any better/easier than that as far as power-demands of a device go.

You are still right that the RME power-supplies should not die so easily. Do yours get too hot maybe, because of where they are placed (lack of any air-flow around them)? Do you ever switch them off or do you keep them running 24/7?

I have a FF800 and had to replace the elco's in the PSU.
I know 1 guy with a FF400, his PSU died a year ago.
So that's another 2 cases RME.
A friend of mine has an ff800, that's still working.
So thats 2 broken out of 3....

3phase...

are you sure it's the actual power supply? The reason I ask is I made a post just yesterday about coming home one day to find all the LEDs on the front of my FF400 lit up dimly (there are usually none lit all all except for the segmented number LED). Freaked me out and I pulled the adapter jack out right away and when I inserted it back in it kind of worked intermittently at first but seemed stable after retrying it a few times. I thought everything was fine and there had just been some weird one time glitch but when I went play any audio on my pc there was no sound even though I could see meters working. When I switch over to bus power everything is normal and works fine. At the suggestion of RME support I was about to locally purchase a new adapter today but decided to test my RME one first both with a multimeter and by operating other 12v devices I own and the adapter is fine and its green LED lights up fine. I'm saddened to now realize there is in fact something wrong inside my Fireface itself, and being out of warranty and out of work for the winter I cannot afford any amount to send it in and have it fixed. I also don't want to be shut down for possibly weeks while sending it away. I don't get paid for what I do but it is my daily passion, I can't afford a backup solution. So, like the other user whose thread I posted in who had the exact same issue, I am left having to run my FF off bus power for the foreseeable future. If I want to upgrade to a higher end RME product I cannot sell mine like this and to use it I must now be tethered to firewire so I cannot use it as a stand alone.
