Is a refurbished Dell OptiPlex 5090 worth buying?

Yes, a refurbished Dell OptiPlex 5090 is an excellent value since these business desktops are durable and sell cheaply used while still supporting Windows 11. Confirm it has an SSD, enough RAM, and a valid license. Compare New vs Refurbished offers and price history across sellers on Shopfox to make sure your OptiPlex 5090 is a genuine bargain.

What form factors does the Dell OptiPlex 5090 come in?

The Dell OptiPlex 5090 comes in tower, small form factor (SFF), and micro versions, so you can pick based on space and expandability. The tower allows add-in cards and more drives, while the micro is tiny and quiet for tight desks. Choose the form factor that matches your needs before comparing OptiPlex 5090 configurations across sellers on Shopfox.

How much RAM does the Dell OptiPlex 5090 support?

The Dell OptiPlex 5090 supports DDR4 RAM, with the tower and small form factor handling up to 128GB across four slots, while the micro version tops out lower. Upgrading to 16GB or 32GB greatly improves multitasking. Pairing more memory with an NVMe SSD is the best value upgrade to keep an OptiPlex 5090 fast and responsive.

Wrong Power Adapter

They sent the wrong power adapter — a 65W one instead of the 90W that the Dell 5090 micro needs. It technically works, but you can definitely feel the performance drop.
