A powerful and reliable PSU is the cornerstone of any desktop PC or workstation. This humble little component is more important than you think. Aside from supplying the electricity to the computer, it can make your PC components last longer and save you some power. The Corsair VS450 White Certified ensures protected transfer of mains electricity to singular circuits, which subsequently power the used parts. The ATX source with a 450 W power is recommended for modest mid-range gaming PCs. The PSU features a 120mm fan that reduces the temperature and extends its service life. You can cut the power supply with a switch. Every PSU has a special label that tells you how effective it is at using the power from the mains. The 80 PLUS tag indicates an efficiency of up to 80 %.
