be quiet! 500W and 600W SFX-L PSUs

I’m constantly on the lookout for new SFF power supplies (in hopes that in the not too distant future I can gleefully gloat at ATX’s demise) and be quiet! has two SFX-L units in their booth here at Computex 2017. There will be two models, the 500W SFX-L-500W and the 600W SFX-L-600W (gotta love self-explanatory model numbers). They are both Gold-rated, feature a single 12V rail, fully modular, have a 3-year warranty, and they’ll include a SFX to ATX bracket. This unit is not semi-fanless, and the be quiet! gentleman I was talking to said the reason is that it’s already …

SilverStone Power Supplies at Computex 2017

We stopped by the SilverStone booth yesterday, and I already covered the prototype fanless 450W SFX-L because it’s just so crazy (in an awesome way). But of course SilverStone had other power supplies to look at, so here they are: First off is a FlexATX form factor PSU, the FX350. As the name implies, it is a 350W unit with Gold-rated efficiency and the 12V rail capable of the full rated wattage alone. Fortunately for SFF builders this is of the shorter 150mm length FlexATX variety. The cables are sleeved, though it’s nothing special. I’m not sure if they’ll do it …

HDPLEX 160W DC-ATX direct-plug review

Up for review today is the HDPLEX 160W DC-ATX, a power supply of sorts, but one that is a bit different than the SFX and SFX-L PSUs I have previously reviewed. What makes a DC-ATX unit different? It is right in the name, it takes a single DC input voltage and from that generates the various voltages needed by a typical ATX-spec motherboard: 12V, 5V, 5VSB, 3.3V, -12V, and the power good signal. That’s all it does though, so some sort of adapter to take AC power from the wall outlet and convert it to that DC input voltage is required to complete the …

Rant: Internal or External?

This is one of a series of mini-rants by your faithful correspondent, John Morrison. These are part of a series focusing on issues in the SFF niche. All content is entirely opinion of John, not of SmallFormFactor.net, and should not be taken as fact. Ahh, the age old SFF conundrum. Do I fit all of the power supply inside the case, or split the perceived volume up and have a power brick under my desk? Is that cheating? Do I include the brick in the final volume of my case? If I do, do I include the volume of my …

Enermax Revolution SFX 550W review

The SFX power supply market must be growing, because it seems like every few months now there are companies announcing new PSUs aimed at SFF enthusiasts. It was late last year that Enermax announced their Revolution SFX series, and today we’re now looking at the Revolution SFX 550W. While Enermax is no stranger to power supplies – and has even sold SFX units in the past – this is their first one aimed at the compact gaming rigs that have become significantly more prevalent nowadays. At a high level, the Revolution SFX 550W features fully modular cables, Gold-rated efficiency, all-Japanese capacitors, and is a 550W …

The DC-DC Solution, An Introduction

As part of a multi-part series, I will be discussing the brave new(ish) world of DC-DC power supplies, their advantages, disadvantages and the technology that powers the smallest of our systems. In the first article, I explain what DC-DC is, why it is a useful product, and run down a few of the more popular brands on the market. [mks_separator style=”blank” height=”2″] [mks_separator style=”blank” height=”2″] What? Using a ‘DC-DC PSU’ as your sole power supply just won’t work. For a system to run (generally), you need to take AC (alternating current) from your mains power, and convert it to the …

SilverStone SX550 Review

On the bench today is the SilverStone SX550, a 550W SFX power supply with Gold-rated efficiency, 80mm fan, and fully hard-wired cables. An interesting unit that slots in between the more budget units like the Bronze-rated ST30SF V2.0 and ST45SF V3.0 that I reviewed recently and the higher-end modular units in SilverStone’s ever-growing line of SFX and SFX-L PSUs. So without further ado, let’s take a look! A disclaimer first before we get started: SFF Network does not currently possess the expertise or equipment to fully test the electrical performance of PC power supplies, and as such, this article should not serve as the …
