Questions about this item

What DDR3 memory does the OptiPlex 990 Mini Tower accept for future upgrades?

The system uses 240-pin DDR3 DIMMs and currently has 8 GB installed. The manufacturer highlights indicate a maximum of 16 GB is supported.

Which component reaches its limit first when the Intel Core i7-2600 runs at 3.80 GHz Turbo Boost for long periods?

The 265 W power supply is the first constraint. Sustained Turbo Boost on the quad-core processor draws more power than light loads, leaving less headroom for drives and expansion cards.

How loud and hot does the Mini Tower get when the 265 W supply, 1 TB SSD, 2 TB hard drive and DVD-RW run all day?

With a modest 265 W supply and integrated Intel HD Graphics 2000, heat output stays low. The single system fan typically runs at a quiet, steady speed during continuous office workloads.
