## 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: Don't Let the SFX Fool You - I had this in my FT03 MINI ITX build until switching cases and upgrading from a GTX 660 ti to a GTX 770 ACX. To this day, I'm sure that the power supply could handle a GTX 770, as I've seen this power supply been used to power a Titan. Build quality of the PSU is great, however be careful not to scratch it, the paint does come off very easily. I had this powering an i5-3450 and a 660 ti which I would let run Folding@Home every day which uses a lot of your systems resources and the PSU never skipped a beat. The fan also is not very loud, I could never hear it, but that was over the CPU and GPU fans. I believe this is one of the very few solid SFX PSU's but if you're okay with it not being modular, it is very solid. I would buy another!
Review: Excellent HTPC PSU - Using this in my HTPC and it works brilliantly. Very quite and super efficient. I have it powering: A10-6800K ASRock FM2A88X-ITX+ 2 WD 2TB Red Drives Some BluRay Drive 1 TB 2.5 inch drive 128 GB SSD GTX 650 Ti 200mm Fan 120mm Fan H80i water pump The CPU is OC'ed to 4.2GHz, everything else is stock This PSU has no problem whatsoever and powers all of the above and is super quiet in the process. Only complaint: I wish the metal bracket that converts the SFX to regular PSU size was black like this PSU and not silver/grey (looks like an old PC case)

### ⭐⭐⭐⭐⭐ Don't Let the SFX Fool You

### ⭐⭐⭐⭐ Excellent PSU but a Stingy Company - 4.5 Stars
*by J***. on October 5, 2011*

1. PSU is heavy in hand. It means Silverstone has used good materials on this product. 2. Black finish looks and feels excellent. 3. VERY quiet in the case. Fan noise is barely noticeable. 4. Enough power for an AMD A8 CPU, 8GB RAM, 128GB SSD, 2TB HDD, Blu-ray drive, and Radeon 5870. 5. I paid for FULL price (now it's $10 cheaper on Amazon) for this PSU and expected to receive a PSU with ALL cables sleeved. This is nearly a standard practice for today's high-end PSU manufacturers. But Silverstone is SO STINGY on sleeving PSU cables. PSU has cables sleeves on 24 pin power wire and a few other wire, but leaves SATA cables, Molex Cables, and the Floppy cable all exposed. I have to pay extra $15 to buy cable sleeves. I should have deducted TWO stars for you, Silverstone. The cable sleeve is something should be done correctly the first time, not on Version 2.0 or 3.0!!
