Question: Will this Power Supply Fit in a Dell Optiplex GX620 Mini Tower also known as  Dell Optiplex GX620 MT?
Document: I bought this power supply to replace the power supply in a Dell Studio 540 MT (mini tower - not the slim version). The original died about 3 and a half years into its use after a storm knocked out the power. The original power supply was always a bit noisy and laboring to run the two drives, original video card and dvd-rw unit.
I really like this new power supply! The old dell tower I placed the Antec into did not fit do to its on and off switch under the plug in cord. + There was a slot that should have hooked into the power supply case on the  top of the dell case. I fixed that with a saw.About 10 mins work to make it fit and them bag, I have a good new power supply.
lolP.S. I did not cut or modified the Antec at all. I just cut to fit the old dell tower.
I ordered this to attempt a repair on a 4 year old Dell Studio which became a brick after a power outage. I test installed the supply without actually mounting it and it worked immediately. The unit is quiet, barely audible with good airflow. There are enough plugs for more hard drives or DVD recorders than the 1 hard drive and 2 dvd recorders I have, and length of the cables was plenty for this mid tower design.
Replaced a power supply that went bad in a Dell desktop computer. Fit exactly as the old one had and solved the &#34;dead&#34; computer problem. I have used Antec Power Supplies and Cases for other computer builds and repairs and find them to be a high quality product.
I bought this to retro into an older Dell XPS system. I was a little skeptical that it would have enough (and the right type) connectors due to the lower price, however, it fits and works perfectly. It also quiter than I expected. A great value.
From Antec so it worked as expected. Fit my Dell Inspiron Desktop well. Plenty of connectors. Runs cool and quiet.
Bought this power supply to support adding an additional video card to my Compaq tower. Removed the old PS and dropped this one in without issue. The power supply is silent - I am very pleased with this purchase.
I purchased this PSU to repurpose my old dual core desktop as a media server. The PSU also supports the older style MOLEX power connectors for those who still use EIDE HDDs. This power supply runs very quiet!
This is an excellent power supply for a standard desktop computer. It will not work in a slimline machine, but if you have a standard sized computer, this power supply is for you. It has 450 watts, with a +4 for the main atx power adapter in case you need it. They also have ample numbers of molex and sata power adapters! Great buy!
Answer: Judging from the pictures I see of the Dell Optiplex GX620 MT I'd say yes it will fit, being it's a standard size cabinet.
