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 powering the PC, it can also improve the component service life and save some money and power. The Seasonic Focus SGX 450 Gold ensures protected transfer of mains electricity to separate circuits, which subsequently power the used parts. The ATX power source with a 450 W is recommended for small Mini ITX PC cases. The PSU conceals a 120mm fan, which minimalises the temperature and improves its service life. You can cut the power supply with a power switch. Every PC PSU on the market has a label that tells you its efficiency. The 80 PLUS Gold tag indicates an efficiency of up to 87 %. Modular cables keep the usual wire chaos in the PC case at bay.
