HORRIBLE Optiplex 9020 Power Supply

Discovered this same [ADMIN NOTE: Profanity removed as per TOU] today in our 9020s we bought for upgrades for our 7010 from last year... What the [ADMIN NOTE: Profanity removed as per TOU] is wrong with sticking to industry standards for testing, replacements, and compatibility for upgrades etc. Same reason we dropped Lenovo line 4 years back.

Looks like Dell is back to their old antics and won't be on our purchasing list anymore. [ADMIN NOTE: Profanity removed as per TOU], can't even change pin out or get an adapter looking at the schematics. Will make sure our premier rep hears about this...

The 9010 MiniTower uses a standard 24 pin power supply.  Perhaps you are talking about the small form cases that use a different power supply ... so that won't help with the 9020 mini towers that use the proprietary power supply.

I did see that there was one seller on ebay selling a 9020 power supply ... and there is only 1 single power supply listed.  So, that shows that people aren't getting these available to sell ... and that doesn't really help at all.

So, the power supply goes out ... Dell says too bad, I guess!

Yes because businesses, government, and institutions purchase hardware on ebay...

It would appear that there is a solution.

I did this over the weekend and it went without a hitch. The cable from ModDIY looks a little different now; you don't need the extra molex to get the second 12 volts...it all comes from the 24 pin connector. The replacement 750 watt power supply I got was a little longer than the oem part and I simply could not fit it in without removing the sliding lock thing inside the case. Once that was out, the psu slid in without an issue and the power supply mounting screws lined up exactly with the original holes. 

I installed an R9 380 video card in the box (which is what generated the need for the new power supply and the ModDIY cable). I'll have to run some video tests to see how it performs but my first test was running F1 2014 with everything turned on and it got an average of 108 FPS.

Which PSU do you use? Cant find anyone with 12V VSB?!

It's a Sentey 725.

I doubt it. The SFFs use a compact PSU, I believe. The Sentey just fit in the 9020 tower case but not without some alteration (I had to remove a sliding bracket that's part of the security lock). 

Even though I had measured an actual 9020 ATX PSU and the Sentey was very close to those measurements, I was concerned it wouldn't fit. To be on the safe side, I went to a local computer store and bought from them for a few dollars a bare standard case. If I couldn't have gotten the Sentey to fit in the 9020 case, I would have transferred everything to the new case. I'm not sure that would be an option if you had a SFF motherboard, though. It would take some measuring. I'd be worried that the ports wouldn't line up properly and that I'd have to get creative with the motherboard mounting posts. Everything is doable if you have the patience though.

Just one last note. The reason I bought the 9020 was because it was a refurb at NewEgg at a really great price and it came with the I7 4770 and a 1TB hard drive. I really would have liked an Asus motherboard with two PCI slots for two video cards, but I couldn't put the pieces together for anywhere near the price of the refurb.

Will this power supply work in a 9020 SFF ?

Thanks for the information.

I bought the SFF for the compactness, so I knew that I would most likely be giving up a lot of flexibility.

I bought mine as a gaming machine to get back into sim racing after many years away from it. So I knew I'd need flexibility. You  could see if it would fit in a standard ATX style case. You can buy cases with power supplies reasonably. Then all you'd need is the adapter cable. It doesn't look like there are too many SFF power supplies that provide a lot of wattage on the Internet. I thought about the 9020 board I have not fitting in a regular case and decided I'd buy a new motherboard if that were the case. The price on the refurbed 9020 was good enough that I could have done that and still spent less than buying all the parts separately.

We run a lot of the SFF Dells at work. I don't deal with them; I'm a Unix guy. But they are reliable and if you don't need to do any additions to them, they run just fine for a long time. Of course, at work, we don't upgrade; we replace.
