Dell SX280 PSU

Hivetyrant · 10-24-2008, 02:00 PM

All right, here's my dilema. I recently purchased a Dell SX280, which happens to be an Ultracompact Form. Well, it has a 220w 13v external power supply. Did some research and found it doesn't have any more powerful versions.

Now my question is would it be possible to buy a more powerful internal power supply for a dell and hav it setting outside of the computer while still hooked up. According to a friend of mine, it's possible, and I'd just need some sort of support for it, but my concern is potential wiring differences and possible motherboard overload. Any ideas on how I should go about getting a more powerful supply?

Not really they are not standard boards and have their own power scheme for the connections, SX280's are purpose built computers to fit a business need.

But wouldn't two Dells be similar, and reverse compatible with each other?

Not necessarily what are you trying to do that requires more power?

This particular SX280 comes with 2.8 ghz(single core), 2 GB DDR2 RAM in DIMM Slots, and a PCI Express Card. I was planning on replacing the two 1G Ram Cards with 2GB versions designed for the SX280, and a compact video card.

I have about a week before the computer comes in, but I'm thinking about just reselling it and cutting my losses to get a computer more towards gaming, unless I can resolve the issues here.

I'm sorry, I mistyped that. It's 220w 12v

It will never be a good for gaming it's just not designed to do that In fact I've never seen one with any expansion slots and there's no room in the case to put a card,

This is an sx280. There is a single PCI Express slot in it, though with some space constraints.

My bad but I still don't remember them having a PCI slot> http://support.dell.com/support/edoc...ut.htm#1103201

Well, I guess I am going to just resell it. Got any suggestions for websites? I was thinking Ebay, but everyone expects you to sell dirt cheap there.

Craig's List?

Yes, you can run it off of a standard desktop PSU.
You will need to fabricate your own plug. I chopped up an ATX MoBo connector and spliced it in to a four way hard drive power plug (from an old Y splitter). This way, I can use any PSU I have laying around.
Simply jumper the power on pin (14/Green to ground/black) to keep the PSU running. I ran mine for months like that until I found one cheap enough on eBay.
One of the downsides is that the fan is noisy and there are a bunch of other wires hanging out of the PSU.
Never had a problem with power or overheating.
For wiring info, check DA-2 pinout or here DA-2 pinout
