Mid-tower case with 400W PSU

The E-POWER EP-2002BB-400 is a black mid-tower chassis built from SPCC steel and supplied with a 400W power supply mounted at the bottom. It accepts ATX and Micro ATX motherboards and provides seven expansion slots for add-in cards. The side panel is solid with no window. This configuration suits builders assembling a standard office or home system who want the PSU included.

Drive capacity and GPU headroom

Internal storage includes two 3.5" bays and two 2.5" bays, while a single external 5.25" bay remains available for optical media. The case accommodates graphics cards up to 360mm in length, leaving room for most mid-range models. CPU coolers up to 160mm tall will fit, but larger tower coolers or all-in-one radiators beyond that height cannot be installed. A 240mm radiator can be mounted at the front if liquid cooling is preferred.

Build practicality and daily connections

The front panel offers one USB 3.0 port, one USB 2.0 port and HD audio jacks for convenient peripheral access. A 120mm fan is pre-installed at the rear, and the layout allows optional 120mm fans at the front, side and bottom for additional airflow. The bottom-mounted PSU position isolates power supply heat from the main component chamber. SPCC construction provides a rigid frame for straightforward assembly and long-term durability.

Questions about this item

Will the included 400W power supply run an older ATX motherboard that still uses a 20-pin main connector?

The PSU provides a 20+4Pin main connector so the 20-pin portion fits legacy boards while the extra four pins stay detached.

How can I verify the front USB 3.0 port is active after I connect the internal header?

Plug a USB 3.0 device into the front port; the operating system should enumerate it at SuperSpeed and file transfers will run at the higher rate.

Does the case ship with the two 3.5-inch drive trays and the single rear 120mm fan already installed?

Yes, the two internal 3.5-inch bays and the rear 120mm fan are pre-fitted; the 5.25-inch bay, the two 2.5-inch bays and optional front, side or bottom fans are empty.
