O2 power supply voltage input ?
Hi,

After missing out on a SGI Fuel auction on Ebay I decided to go for an O2 and ordered parts all over.
I am awaiting an O2 R5K 200MHz with 128MB from the land of the rising sun, so it's used to 100V :-)
As I have 230V AC over here, is the O2 Power supply auto voltage select?
Looking at various O2 power supply (Sony) pictures, there is no mention of input voltages or no sight of an voltage selector switch.

Thanks

Switching power supply. It should take 230V mains without issues.

Hi, before you plug that O2 not sure if you already do so.
I also live in a 220v country at first used a 110-220v step down converter for the O2 and Octane and they worked fine.
One day i realized that the PSUs where universal so i decided to get rid of the step down converter an plugged them to the wall.
The power supply's on my o2 and Octane blow up and give out lots of smoke, they where dead i have to order new PSUs from Ebay.
From that day i always used step down converters on my SGIs.

Hi,
That is too bad. My O2 came from Japan so was 'used' to 100V. Luckily it works just fine on 230V.

I've had a worldwide-input switching power brick fail when I moved it from 120 ( using a step-down transformer) to 240 for the first time in the space of about 1 minute, which is what I blame it on. My various older computers that had been only used on 120 while in the states generally have had no issues with changing to the 240-ish found in NZ, but sometimes the AC filtering caps fail soon afterwards.

(05-03-2020, 10:15 PM)Hi KiwiME, Wrote:  
I see that you are also a nz user. I am as well, so thought I would reach out.

I am a professional photographer living just outside Christchurch, and have a couple of SGI machines. An O2 and an Octane that I am trying to get going, after many years in storage.

How did you come to be interested in SGI? Was it related to your engineering career? Or something else?

I initially got interested in SGI in the late 90's when I was transitioning to digital photography, one of the labs I used was offering retouching, using Alias Eclipse on an Indigo2. I looked at them and considered going with an O2 and Photoshop 3. Then reality kicked in and I bought a Mac instead for about 20% of the price. But I always wanted one, and some years back I managed to pick up a couple of bunches of machines people were getting rid of for peanuts.

I have a bunch of spare stuff for O2's and Octanes if you are interested, I like to trade and have made contact with a few others here in NZ, as shipping from overseas is a hassle, but sometimes a necessary one. If we NZ users can trade amongst ourselves, all the better to save a bit of money on shipping, and keep these great little machines going strong.

Cheers,
Jason.
