The B5 power supplies provide maximum flexibility for system builders with a fully modular design and a small chassis across all models. At 150mm length, the B5 power supplies provide solid, affordable power for all manner of system builds and cases.

The ultra-quiet 135mm Fluid-Dynamic Bearing fan becomes silent when coupled with EVGA ECO mode to turn off the fan in low to medium loads. The larger fan and carefully tuned profile creates a quieter experience than the B3 power supplies.

Featuring an LLC Resonant design + DC to DC converter, EVGA B5 power supplies are up to 89% efficient - well above 80 Plus Bronze requirements. Moreover, the B5 power supplies are designed with modern standards, including ATX V2.52, for performance and stability.

Inlcudes the PSU & power cable, one MB cable, one CPU cable, one VGA cable, 2 SATA cables, 1 PERIF cable, one FDD adapter, power supply tester, and four case screws (didn't realize these were missing from the main image until after I took the picture, but they are included (though not in their original bag))!

Does not come in original packaging! In order to ensure the product ships as safely as possible, this item may be placed in the packaging for the part I replaced it with. The item you are receiving is the one referenced in the listing name/featured in the images above.

I did not see any dust buildup within the PSU, but I cannot guarantee that none is present.
