Easy to remove and reinstall. Fit perfectly in the case, as it should, and holes lined up great. Would buy again if needed. ### ⭐⭐⭐⭐⭐ Very good choice for desktop power supply *by T***N on August 25, 2024* I purchased this to replace a failed power supply in a Dell Optiplex 990. Unit works well and an old computer has new life. ### ⭐⭐⭐⭐ Works in the Dell Optiplex 790 SFF (Small form factor). *by P***1 on March 19, 2025* So far so good, re installing this was not bad on my Dell Optiplex 790. It is kind of crazy that this computer came out in 2011, and here I am 14 years later fixing its first issue. Aside from upgrading the RAM, SSD and getting the highest CPU for this a few years back this little machine has been a beast to say the least. I am a developer by trade and all of my IDE's and tooling and containers and virtual machines run off of this machine without issue. The only thing that I think sometimes holds me back from doing even more is the 32GB RAM limitation. Looks wise this appears to be a almost perfect replica of the OEM power supply. If you have the 790 SFF (small form factor) then this is the right PSU. I do notice that it is a bit lighter than the OEM and that the power port where you connect the power cable is upside down compared to the OEM as well. Cable length is similar to the OEM. I hope that this is as durable as the original as this PC is on almost 24x7x365. The only reason that I am taking off a star from this is that I can audibly hear the fan in this new PSU where my other one was silent. I have read a ton of reviews and it seems like a crap shoot if this is going to last more than a few months, but without more reviews we will never know true durability. I certainly would not want to be replacing this PSU for a few years at minimum. If this PSU does die pre-maturely then I will update this review. ## Frequently Bought Together - D250AD-00 H250ad-00 250W Power Supply for Dell Optiplex 390 3010 990 790 DT 530s 537s 540s 545s 546s 560s 570s 580s Vostro 200s 220s 230s 400s Studio 540s Slim Desktop DT Systems L250NS-00 - S-Union 240W Power Supply Unit Replacement for Dell OptiPlex 390 790 960 990 3010 9010 Small Form Factor System SFF H240AS-00 H240AS-01 H240ES-00 D240ES-00 AC240AS-00 AC240ES-00 L240AS-00 PH3C2 - POINWER H240AS-01 H240AS-00 L240AS-00 2TXYM 3WN11 240W Optiplex 7010 SFF Power Supply for Dell Optiplex 390 790 960 990 3010 9010 Small Form Factor Systems CCCVC 3RK5T ac240as-00 D240ES-00 --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.hr/products/81711498-h250ad-00-250w-power-supply-for-dell-optiplex-390-3010](https://www.desertcart.hr/products/81711498-h250ad-00-250w-power-supply-for-dell-optiplex-390-3010) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-07-31*
