Corsair TX750M Series, 80+ Gold Certified 750W Semi Modular Power Supply

I like the Dell Optiplex line of business computers. They last forever, provide good performance, and run much more stable than just about anything else out there. However, I also occasionally like to game. On the Optiplex 7020MT, Dell uses a proprietary 8 pin plug, and they draw all of the power into the motherboard and they use a special cable to power the peripherals (DVD drive, hard drives, etc.) off of the motherboard power. Also, they only use the 12v rail and they don't pull any 3v or 5v from the power supply, but instead generate that on the board. This means that replacing a Dell power supply with anything less than a 750 Watt 80+ Gold Certified power supply will likely cause issues as the 12v rail cannot provide enough current for the Dell engineered design.So I needed a power supply that could power my computer reliably, power by heavy power draw gaming graphics card, and not clutter the inside with a bunch of unused cables. With this setup I can not only power my graphics card, but also the peripherals off the power supply directly. This also reduces the work the power circuits on the motherboard, and that can only improve lifespan and stability. If you are looking to do the same, and you specifically have a Optiplex 7020MT, this is the power supply you are looking for. This will not work if it is not the Mid Tower model.If you are just curious why the fuss. I already mentioned the other positive attributes of the Optiplex line. I should also mention that I got a professionally refurbished Optiplex 7020MT for $200 with a Quad Core i7 CPU and 16GB of RAM (no operating system). So the price of your display adapter, an SSD, this power supply, and about $200 makes for a very, very stable daily driver computer that will have no problems playing the occasional AAA game.

Great product but the first one i ordered was broken it literally was used and returned too because it was broken the package of cords inside was ripped open so they just re shrink wrapped the box and re sold it to me as brand new which it clearly wasnt or else the cords inside wouldent have been ripped open and the plastic bag around the power supply was missing the second one i ordered works great and the wires were still sealed inside the box unlike the other one that was broken with a ripped open package of cords inside pretty easy to hook up so if you do it right and think you did it right but its not working try putting your old power supply back in and if the old one still works and the new on doesnt you got a faulty one just return it as dead upon arrival dont think it was you doing something wrong and just keep the broken unit

Quiet for a 750-watt power supply. Black color. Clean.built like a tank, I won't throw it like a football, but I feel the material is really strong.with the ability to add and remove cables. I can use what I need and keep the cable down in the PC.Overall, I love it and ready to game on a high-end PCHere my spec if anyone interested and asks any questionsAsus ROG x570 E gaming MotherboardAMD 3700x 8-core 16 threads 3.6 GHzASUS AMD 5700rx 6 GBCorsair 16 GB 3000 MHzSamsung Evo 500 GB Plus m.2

Ample power to run almost any hardware, and very quiet, and easy to install. Best part is the modular cable design so you don't have that rat net of excess cable in the cabinet you don't use. But can add it later as you expand. Long life specs are a plus too!
