My Buying Guides on Computer Dell Optiplex 990
When I decided to purchase a Dell Optiplex 990, I wanted to make sure I chose the right configuration and features to meet my needs. Here’s the guide I followed that might help you too.
Understanding the Dell Optiplex 990
The Optiplex 990 is a business-class desktop from Dell, known for its reliability and solid build. It’s a great choice if you want a durable machine for office tasks, light multimedia, or even some moderate computing workloads.
Choosing the Right Form Factor
The Optiplex 990 comes in several form factors:
- Mini Tower (MT) – Offers the most expansion options and easier upgrades. I picked this because I wanted room for extra hard drives and better cooling.
- Desktop (DT) – A smaller footprint, ideal if you need to save desk space but don’t plan on many upgrades.
- Small Form Factor (SFF) and Ultra Small Form Factor (USFF) – These are compact and great for tight spaces but limited in upgrade options. I avoided these because I like to tinker and upgrade components.
Processor Options
The Optiplex 990 supports 2nd generation Intel Core processors (Sandy Bridge), such as Core i3, i5, and i7. I recommend:
- Core i5 for a balanced performance and price, suitable for most users.
- Core i7 if you need extra power for multitasking or heavier applications.
I found the i5 to be sufficient for my daily tasks, but if you plan on more intensive workloads, consider the i7.
Memory (RAM)
The system supports up to 16GB of DDR3 RAM. I started with 4GB but quickly upgraded to 8GB to improve multitasking. If you’re running memory-heavy applications, aim for 16GB if your budget allows.
Storage Choices
Originally, these computers came with traditional HDDs. I upgraded mine to an SSD for much faster boot times and responsiveness. Here’s what I suggest:
- If you want speed, go for an SSD (at least 240GB).
- If you need more storage and budget is tight, consider a combination of SSD + HDD.
Graphics Capabilities
The Optiplex 990 typically includes integrated Intel HD Graphics 2000, which is fine for regular office work and video playback. If you plan on light gaming or graphic design, consider adding a discrete graphics card. I stuck with integrated graphics and found it adequate for my needs.
Ports and Connectivity
Make sure the model you choose has enough USB ports (USB 2.0 and USB 3.0), audio jacks, and display outputs for your peripherals. The Optiplex 990 offers:
- Multiple USB ports
- VGA and DisplayPort outputs
- Ethernet port for wired networking
I liked having DisplayPort for connecting to my monitor, so check your monitor compatibility.
Operating System
Many Optiplex 990s come with Windows 7 or no OS at all. I installed Windows 10 for better support and security. If you’re comfortable, you can also install Linux.
What to Look Out For When Buying Used
Since the Optiplex 990 is an older model, I recommend:
- Checking the physical condition for any damage.
- Verifying all ports and components work properly.
- Asking if the original power supply is included.
- Confirming what upgrades have been made (RAM, storage, OS).
Final Thoughts
For a budget-friendly, reliable desktop, the Dell Optiplex 990 is a solid choice. With some upgrades, it can still handle everyday computing tasks smoothly. My experience upgrading the RAM and switching to an SSD made a huge difference in performance, so keep that in mind when you buy.
I hope my buying guide helps you make an informed decision!
