[Product Introduction]
High efficiency with 80 PLUS Bronze certification
The ET650-B/ET550-B features an 80 PLUS Bronze design for reduced heat and power savings.
Test results show an efficiency range of 82%-85% from 20%-100% load.
Continuous power output at 40°C operating temperature
It goes without saying that a PC power supply's continuous power output (continuous operation) is one of the key indicators when comparing PC performance. SilverStone power supplies are renowned for their stable continuous power output. Taking into account the upcoming trend of low-power systems, the ET650-B/ET550-B is capable of continuous output at an operating temperature of 40°C and can even start from 0°C.
■Class-leading single +12V rail/PCI-E 8-pin and PCI-E 6-pin connector support
The powerful single +12V rail design is ideal for future upgrades to high-end components and overclocking.
The independent single rail features four 8-pin PCI-E connectors (6+2), supporting power supply to mid-range and higher-end video cards.
*Please note that not all products are supported due to power supply issues. Please check the power consumption of the video card you are using in advance.
■Low-noise 120mm fan with a minimum of 18dBA
Designed for use in a variety of applications, the "Essential Series" ET650-B/ET550-B also takes into consideration noise levels, one of the most annoying factors for users.
The 120mm fan provided for exhaust and cooling is variable, maintaining a rotation speed of 2000 rpm even at 100% load.
Its minimum noise level is also extremely low at 18 dBA, ensuring that it won't be a noticeable rumble inside a sealed PC case.
■Flat cable for easy management
Round cables are used in PC power supplies that prioritize visual appeal. In contrast, the "Essential Series" ET650-B/ET550-B uses a flat cable.
A major advantage of flat cables is that they can be folded and stored compactly inside the PC case. There's also no risk of breakage.
As a result, they may offer more flexibility than round cables depending on the space available inside your PC case.
