Be Quiet Straight Power E9 CM 580W PSU Review

Out of the box, the Straight Power E9 CM 580W power supply is an impressive looking product. The smooth, matte black chassis with the slim orange detail around the fan and the eccentric fan grill grant this power supply a very unique appearance. The size of the chassis is only 160mm, not longer than ATX standard units, making this power supply suitable for installation inside all ATX-compliant cases.

Be Quiet placed the label with the unit’s electrical specifications and approvals at the left side of the unit. It will be visible from a windowed left side panel in cases with the PSU compartment either at the bottom or top of the case.

The company logo is subtly engraved on the right side of the unit. The logo is barely visible but it will also be upside down with the power supply installed inside most ATX cases.

The rear is entirely perforated to allow for the air pushed by the cooling fan to escape towards the outside of the case. The unit uses a standard A/C power cable and there is a standard on/off switch right next to the A/C cable plug.
