Silverstone SST-ST45SF V3.0 80 Plus Bronze SFX Power Supply - 450 Watts [SST-ST45SF v 3.0]

Silverstone has revised version 3.0 of the compact SFX power supply SST-ST45SF with a nominal output of 450 watts especially with regard to gaming PCs and home computers. Thanks to the SFX format, this power supply is primarily intended for mini cases (mostly in mini-ITX format) and offers high performance with minimal dimensions. In contrast to its predecessor, version 3.0 uses a larger and therefore quieter 92 millimeter fan with an optimized fan curve. The SST-ST45SF V3.0 thus provides a perfect solution for almost all users who want to combine high performance with low volume.

In addition, the performance on the 12-volt line, which is important for gaming graphics cards, has been slightly increased to a full 450 watts (37.5 amperes) and with overload protection (OPP) and undervoltage protection (UVP) are available in addition to the previous overcurrent protection (OCP), Overvoltage protection (OVP) and short-circuit protection (SCP) are additional protective circuits . Instead of a 12 V line that is split several times, this version has a very powerful single rail and is therefore even suitable for multi-GPU systems.

This is also illustrated by the connections, where there are two PCIe power connectorsare present - a 6+2 and a 6-pin. In addition, a 20+4-pin, a 4+4-pin, three SATA, two 4-pin Molex and a floppy connector are available for the mainboard and peripherals. But the ST45SF is also in the top league when it comes to efficiency and achieves an efficiency of up to 85 percent and in the European 230 volt network even up to 87 percent, which is why the PSU has been awarded an 80 PLUS bronze certification is. An adapter panel for mounting in ATX cases is included in the scope of delivery.
