The PSF-400B from its layout may remind on fore gone ATX standards but, compatible with all current standards and certified by TÜV amongst many others and with a fixed voltage of 230V being the European standard, the PSF-400B is a reliable and efficient companion for modern IT structures which thereby also fulfills all ENERGY STAR 5.0 requirements as stipulated by the EU.Dedicated majorly to the 19 IPC / UNC solutions ranging between 2U ~ 4U where the PSU position is delicate and/or tricky and the cooling fan MUST blow out the rear owing to highly limited height issues of the related chassis.
