Your situation helps make my case for hooking any computer to a UPS, not a wall outlet or surge strip. The AC voltages feeding the power supply can vary enough to cause your DC output voltages to be out of acceptable range, low and high. Now if some electrical expert will give us the percantage of voltage variance that is acceptable, we will have lots more to work with. My uneducated guess is 10% which would allow the widest acceptable range for a 12 volt output to be from 10.8 to 13.2. That seems too wide. 5% seems more realistic, 11.4 to 12.6. Not quite. Switch mode power supplies used in today's computers use feedback circuitry to maintain stable output voltages for ordinary input voltage swings. If the input voltage increases 10%, your output DC voltages will NOT. If it was a linear supply, then yes, but switch mode supplies just don't do that. My SeaSonic S12, for example, is rated to work at ANY voltage between 100 and 240VAC. Not just 110/220, but any voltage between. 179.8v would be fine for it. That being said, I too recommend a UPS for any computer. This one is on an APC SmartUPS 2200VA unit--and all of my machines are on a 550VA or better. Most are on APC 1250VA units. It doesn't make sense to me to blow $1k on a computer, and then settle for a $7.99 power/surge strip from Wal-Mart to protect it. As far as output tolerances, generally, +/-5% is considered nominal for the 3.3 and 5.0 rails, and +/-10% is nominal for the 12v rail. That leaves a range of 3.135-3.465v, 4.75-5.25, and 10.8-13.2v. While his +3.3 and +5.0 rails are supposedly beyond that, we won't know anything until a multimeter is used to determine the real voltages. Onboard sensors are horribly inaccurate. Even if those numbers are accurate, they still aren't so far off as to cause a problem.

This has always been connected to a UPS.

[H] USB - PS2 convertor and Microsoft Ergo 4000
Hi, Last week I got a Microsoft Ergo 4000 keyboard. This is just the best keyboard I have ever used. The only issue is it wont work with a usb - ps2 convertor. I need this to work to plub it into my KVM which is PS2 only. I did some searches and found everyone saying the keyboard will not work with a PS2 adaptor. Does anyone know why? Is there maybe a more expensive adaptor that will work? I really can't live without this keyboard now its just so nice but I really have to get it working through the KVM. It doesn't look like they make a PS2 version either :-( Thanks Gary Hunter Systems Engineer - Core Services Cendant TDS - Galileo International (+1) 303 - 397 - 5035 (Office) (+1) 720 - 231 - 0965 (Cell) The information in this electronic mail message is sender's business Confidential and may be legally privileged.

Re: [H] USB - PS2 convertor and Microsoft Ergo 4000
Don't know why it won't work in PS2, but I bought a Ergo 4000 a while back for my home machine. I like it quite a bit--I was avoiding all MS keyboards since the original MS Natural, but I finally found one that I think is a replacement for it. The only real downside for me was that it is different enough to make going between it and even another MS Natural (pre-4000) difficult. To that end, I decided to make my input devices the same for both my home machines and work machine. Now both have Ergo 4000's with MX1000 mice. :) My only real concern now is that I very much doubt that it will last nearly as long as those old MS Naturals did, but oh well.

RE: [H] USB - PS2 convertor and Microsoft Ergo 4000
Yeh Mine replaced the original MS Natural. From what I've read it probablly wont last as long but my Natural keyboard must be at least 8 years old.

RE: [H] USB - PS2 convertor and Microsoft Ergo 4000
Regular PS2/USB keyboards autodetect which interface they are plugged into and change their signalling/power accordingly. I'm guessing that the Ergo 4000 is using a new controller chip from the previous models and does not support this dual mode of operation. Seems a little odd, the savings in that are going to be very very tiny (several cents probably). I wouldn't be surprised to see more going this route. You may be able to get a PS2 port that connects to USB, but I don't think youd get a USB port that connects to PS2. -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Hunter, Gary Sent: 25 February 2006 18:49 To: The Hardware List Subject: [H] USB - PS2 convertor and Microsoft Ergo 4000 Hi, Last week I got a Microsoft Ergo 4000 keyboard.

RE: [H] USB - PS2 convertor and Microsoft Ergo 4000
Because the Ergo4000 uses the new managable HID, there is no way to make it PS2 compatible. This is because it can be mapped to work as multiple devices as well as having programmability. So, you'll never (never) find a PS2 connector that will work with this. -Original message- From: Neil Davidson [EMAIL PROTECTED] Date: Sat, 25 Feb 2006 17:04:02 -0600 To: 'The Hardware List' hardware@hardwaregroup.com Subject: RE: [H] USB - PS2 convertor and Microsoft Ergo 4000 Regular PS2/USB keyboards autodetect which interface they are plugged into and change their signalling/power accordingly.

How did I know Chris would have the answer, even if it was one I didn't want to hear :-( Is there something close to it that is PS2 compatable.
