SFX Ultra Quiet 450 Watt Power Supply - 18 Decibels

Sound Level 18Dba - 80 PLUS Gold Certified Energy Efficient - SFX Small Form Factor - Modular Design

After successfully expanding and leading SFF(small form factor) cases and SFX PSU into the DIY (do it yourself) market, engineers have continued their push for
advancement in these categories by releasing a true upgrade-worthy small form factor power supply. Despite being half the size of a regular ATX power supply,
this small form factor PSU can still produce continuous power output of 450W. Its 80 PLUS Gold level efficiency is a great leap from the previous SFX best of 80
PLUS Bronze and the full modular cables is also the first of its kind for this form factor. To enable users to easily take advantage of this excellent SFX power
supply, an adapter is included to convert to mount in any ATX case in addition to ones that fit only SFX. For SFF users is more than just an upgrade, it is an
important milestone for DIY desktop computer.
