On the subject of video card upgrades I was checking on power usage and the XPS 400 only ships with a 375 watt whereas the X1900XTX suggests a 450. I was reading on Firing Squad that a guy with a near identical system to what I’m getting put one in without upgrading and it’s working fine, but I’m paranoid.
anyone here ever upgrade a dell PSU and if so, what brand/model did you buy? I hear theyre rather peculiar
The best thing to do is to call Dell’s tech support line. Tell them what you’re planning to do and ask them to give you the part numbers for all of the compatible power supplies. They’ll do that, then give you the number for “spare parts”. Buy a refurbished one.
They will probably be WAY more expensive than they should be, though, so it might be better to just try using the one you have.
Edit: The sales people wouldn’t know. Call tech support.
As for whether that PSU is proprietary, I’m not sure. I left before the new rebranded models were launched, but if you check out the specification sheet and the user guide, there is nothing that leaps out as obviously non-standard.
Yeah, I don’t spend a whole lot of time with Power Supply pinouts, myself.
So I looked at the pinout you gave me and at an ATX 2 spec, and it looks to me like they are the same… I would maybe look for somebody that, like, knows, though.
If it were me, I would at least call tech support to see if they could tell you whether it’s proprietary. Either way, get a coupleof prices for dell-provided PSUs. It shouldn’t take more than 30 minutes at the absolute most, and if they are reasonably competitive, that could save you some headaches. If you upgrade the PSU with a Dell part, it will assume the existing warranty of the machine.
This website sells custom PSU’s especially for Dell machines (the key feature on these PSUs is the correct connectors and the lack of an on/off switch so that it fits into the Dell case w/o havning to cut a custom hole in the back of your case):
