OptiPlex GX150 SFF won't boot
Posted by 1avacast@reddit | retrobattlestations | View on Reddit | 12 comments
My Dell OptiPlex GX150 SFF recently died on me, and when I plug it in I just get 2 clicks, and it shuts off w/ an orange light on the motherboard. From what I can tell it's the PSU but was wondering if anyone has been able to repair the PSU instead of replacing, as the replacements are way out of my budget (100w psu w/ 20 pin into the mobo and 4 pin into the hard drive) and I can't find any cheaper ones with the same config.

The PSUs had one tiny component inside fail a lot, especially the lite on ones.

Turns out it just needed a CMOS reset and now it works lol
TechIoT@reddit
Yay! I love it when that's the fix!

Would there be replacements available for cheap, and would it be decently easy to replace?
TechIoT@reddit
Replacements should exist, it's a standard ATX PSU by now (tho I'm not sure if the 150 is that strange one with the P3 or not)
Most if not all Pentium 4 Dells are standardized ATX.
If possible I'd see if you can get the power supply repaired as most replacements may also fail randomly.
Good luck!

Just a note - OP is talking about the SFF model specifically; that is not a standard ATX PSU in a physical sense. The shape is very much specific to these machines. As such, a standard ATX PSU should do for testing purposes - as far as I can tell, the pinouts are standard - but not as a permanent replacement. What might work is a PSU from the later GX260/270, which is a higher rated (160W) part, but I can't tell for 100% definite if they're fully physically compatible.

I could do a case transfer to like a cardboard box or something, used cases are pretty cheap on local marketplaces

I'd recommend buying a Dell branded Delta PSU If you can which fits in the case.

Perhaps you can find a PicoATX Power supply? And fabricate a metal thing to sit in the back to hold the IEC connector?
I'm not sure that will have enough juice tho

Sorry for asking so much but what is the part that needs to be replaced? Also the GX150 does have a P3, don't know if it's the "weird one" you are talking about

I use a pico psu with mine

Do you know if the motherboard has ever been recapped? I did a whole lot of motherboard replacements in these when they were a lot newer than they are now.
