I need to purchase a new power supply for a Dell PowerEdge 800 (it's about 6 years old). I haven't had to purchase a power supply for a Dell in a LONG time, but I seem to recall that Dell PS specs were a bit different. I can't seem to find any doc on whether the PowerEdge 800 is a standard ATX or whether it's s Dell special.
Anyway, it is a Dell 0GD278 420 Watt power supply. I'm pretty sure I can get a refurb for $50, but if there's something new that's just as adequate, I'd prefer to get that. This seems to run more than $130 brand new, which seems... high.
So it turns out there is more to this than the cabling, as I can't get the two power supplies (two different manufacturers as well) I purchased to even power on. Throw in the old one (which I believe is dying, hence the issue), and it powers right up. I have noticed that the original supply is always on - the fan always spins, where as the other ones don't do anything whether they are in the machine or not.
Basically, the machine is randomly locking up. I'm fairly certain this is not a software issue, as there's nothing in the logs to indicate a problem. One minute it is sailing along, the next minute totally non-responsive. The only indication of a problem is the flashing amber light on the front of the box, which, according to the doc, indicates and electrical issue. The diagnostic indicators don't show any problems, either.
I guess it could be the motherboard, but that would not make me happy.
A computer power supply is a really simple thing. I'm confused how the two replacements don't do anything. In general, there is an almost universal power cord for PC power supplies, and almost all of them have a switch on the back to change voltage, and a switch to actually physically turn the PS on.
It may be a stupid question but did you have the new PS set to the correct voltage, and was the power supply switch set to the on position? This is not the same as the power switch on the front of the PC.
Best Buy (the only computer store in town) only carried two brands - RocketFish and another brand. While they both had on/off switches, they did not have a voltage switch.
The original PS seems to be set somewhere between totally off and on - so the PS seems to always be on even when the computer itself is powered down (there's no on/off switch or voltage switch on the original, either). There's always a light on even when the machine is "off". And even when the PS is out of the machine and plugged directly into an outlet with nothing attached, the fan spins.
I've done some reading, and apparently these supplies are proprietary - but I don't get why this isn't better documented. I've had power supplies go in all sorts of machines - but I've never had something like this come up. Really frustrating.
Thanks, works great. The new preview version of Opera does support gmail pretty well, not perfect yet but I'm sure it will be closer eventually. But the browser itself is pretty unstable at this point.
