## Overview

The SilverStone Technology 450W SFX Power Supply is engineered for efficiency and reliability, featuring an 80 PLUS Bronze rating, a robust single +12V rail, and active PFC technology, making it an ideal choice for compact and powerful PC builds.

## Description

ST45SF is compatible not only with chassis that use SFX power supplies but also in smaller ATX chassis with the included adapter bracket. Despite its small size, the ST45SF has features that one would expect from an elite ATX power supply such as 80 PLUS Bronze level of efficiency, temperature controlled fan, 50℃ temperature rating, and reliability for 24/7 operation. Enthusiasts oriented features are also present with single +12V rail and 8pin/6pin PCI-E connectors to fully support multi-GPU systems.

Review: Like a small nuclear reactor in your small PC, minus the small amounts of radiation - I got this PSU for my shoe-box sized Thermaltake Power Supply Mini Case Mini ITX 200 VL52021N2U to replace the included ThermalTake 220 watt power supply unit, and they both seem to be the exact same size. However, the SilverStone is much beefier and the build quality is very impressive. With a Core i5 2500K Sandy Bridge CPU and a Radeon HD 6850, the 450 watts should be more than enough. It was really nice of SilverStone to include four black case thumbscrews and four black mounting screws since the ThermalTake ones were pretty crummy. 6-pin AND an 8-pin PCIe power connectors really simplify things if you get a powerful video card. The 80 Plus Bronze rating shows you're getting a thoroughly modern and efficient PSU in a SFX form factor, although you do pay the price for it. I also considered a SeaSonic 350w (less power, too plain) and an Athena Apollo 470w (never heard of them, no 80 Plus). I did a quick check of the voltages and all three rails, 3.3v, 5v and 12v, were slightly over while idle, which I think is good. In practice, it has been absolutely rock stable and amazingly quiet even under load. If you are building a mini-ITX PC, you don't have many choices, so I would highly recommend spending a little extra and getting the SilverStone ST45SF. The power supply is the foundation for the stability of your entire system and this one makes very few compromises for its SFX form factor. Lastly, it's also very quiet, easily drowned out by my video card and CPU fan even at idle. UPDATE: So mine failed (Aug 7, 2011). When I turn on the PC, the fans would spin a few seconds, then turn off, and repeat this forever. I RMA'd it with SilverStone and they sent a new replacement unit within a few days! So even though America is crumbling around us, SilverStone came through with awesomeness and they deserve a beer. Fingers crossed this one lasts longer. UPDATE (Mar 29, 2012): It's still going strong, surviving many torturous 4+ hour gaming marathons and it has the brutal job of exhausting the heat from the CPU as well as its own heat (the GPU is off in its own thermal world). It's brutal because of how tiny the case is and how much power I tried to stuff in it, but my PC has been absolutely stable with not a single crash or unexpected shutdown. *No need to knock on wood*
Review: An excellent PSU for small builds! - SO cute and little, quiet, and works well. I had it for almost no time, because it didn't seem strong enough to run my AMD 7950 GPU, but I wanted to find out. It really isn't supposed to; AMD states a minimum of 500 watts and some amount of amps on the 12v rail that I thought this had, but whatever. Live and learn. I do wish the cables were modular on this model at no extra cost, but whatever. This product is truly a marvel; it really hits you how small this is when it's in your hand.

### ⭐⭐⭐⭐ Small Form Factor!
*by J***H on December 13, 2012*

Used this for my first PC build. I'm still waiting on one more part to arrive before completing my build and firing it up for the first time to see if this power supply works. Will update rating if anything goes wrong. Chose this power supply for an HTPC build using the Silverstone ML03B case (also purchased here on Amazon). I chose this SFX power supply to give more room in the case. It has all of the connectors that I need and then some. The reason for 4 stars instead of 5 is because the ATX cable was almost too short for my build. The case allows me to install the PSU either fan up or fan down, but the length of the ATX cable only allows this PSU to be installed in the fan up orientation, which places the fan away from the vent in the case. Some of the blame is on me for not double checking measurements. The placement of the ATX connector on the back of the MB seems to be pretty standard (for intel boards at least), and this PSU was recommended for this case on the Silverstone website, so I would have expected to work a little better. All in all, I'm pretty satisfied with this PSU.
