German PSU maker be quiet! Had several new power supplies on display at Computex. Perhaps the most interesting for small form factor enthusiasts are the two new SFX-L power supplies. The aptly named SFX-L-500W and SFX-L-600W are fully modular 80+ Gold rated power supplies that are not much bigger than the 120mm temperature controlled fan that cools it.

SFFNetwork examined the new PSUs at Computex.

According to AnandTech, be quiet! Is using High Power as the OEM for these power supplies rather than its usual partner FSP. The High Power platform offers up a single 12V rail design that supports multi GPU setups with the inclusion of 4 PCI-E power connectors. At least on the 600W variant (not sure on the 500W) the PSU is rated at 50A on the 12-volt rail, which is nice to see. The fan does not support spinning down to zero when under light load, but it does spin down to lower RPMs and has a temperature controlled fan curve that be quiet! claims is sufficient for even noise sensitive applications like HTPCs (hopefully Lee gets his hands on these soon and can confirm the advertised specs).

Both of the new small form factor (SFF) power supplies come with a three-year warranty which seems to be pretty standard for power supplies these days though five would be nice to see especially when they are going to be going into tiny cases with less airflow than the traditional ATX desktop. Speaking of ATX, the SFX-L PSUs come with an adapter that will allow you to install the SFF unit into a standard ATX power supply mount should you want to use it in a larger case.

The 500W and 600W PSUs have US MSRPs of $109 and $129 respectively.

Introduction and Features

Introduction

In this review we will be taking a detailed look at High Power’s new Astro GD 1200W power supply. All of the power supplies in the Astro GD Series are fully modular, have a single +12V output, and are 80 Plus Gold certified for high efficiency. There are currently sixteen different power supplies in the Astro Series and nine models in the fully modular Astro GD Series. The new AGD-1200F is king of the hill with the highest rated output of 1,200 watts.

Along with 80 Plus Gold certified high efficiency, the Astro GD1200W power supply has been designed for quiet operation. It uses a dual ball bearing 135mm fan and a smart fan speed control, which automatically switches between two operating modes: silent mode and cooling mode. Unlike some other power supplies that keep the fan turned off during low output, the AGD-1200 fan spins all the time. The Smart Fan Control adjusts the fan operation mode automatically according to the system loading and ambient temperature for quiet operation. The fan speed starts out slow and quiet and gradually ramps up as the load increases. The PSU also incorporates an off-delay fan feature that keeps the fan spinning for a few seconds after the system is turned off.
