SilverStone SX500-LG 500W Power Supply

SilverStone’s been doing a fantastic job lately in catering to a segment of the market that often goes overlooked by major power supply vendors: the SFX form factor. Today, we’re going to take a look at their latest unit to enter the fray in the SST-SX500-LG.

Good day to you, humanoids. Are you ready for yet another power supply review? Excellent. When you get back from the coffee shop, we’ll get started.

Okay, are we finally all here now? Meh, that one guy in Phoenix can catch up with us later. Time’s wasting, and we need to start talking about today’s review sample, the new SilverStone SX500-LG. This unit champions a new variation on the SFX form factor called “SFX-L.” What does that mean? Well, the “L” stands for “long,” essentially. No, it doesn’t stand for lutefisk. See, SilverStone’s been wanting to put larger fans in their SFX units, and cram in a little more power without compromising on quality. But the traditional SFX form factor is a little too restrictive for that. Solution? Lengthen the housing.

And what features does this new longer SFX unit promise us? Why they’re printed right on the front of the box. Let’s look at a few of those. Intelligent semi-fanless operation? I hope it does calculus or can handle a serious debate on the ramifications of civil disobedience in today’s hostile legal climate if you’re making promises like that. Are all the cables flat? Uh… that’s good up to a point. Single 12V rail? No problem there at this power level. Strict regulation with low ripple and noise? You let me be the judge of that, SilverStone.

On the back of the box, we find a bit more marketing goodness. Fully modular? Yay! Hmm… going by their fan curve chart, I’m not seeing much to be hopeful for on the fanless mode. Looks like it’s only good for fanless operation up to about fifty watts or so. We’ll find out for sure during load testing.

I just found a connector count. He speaks with a Romanian accent and says “Blah!” a lot while waving fistfuls of power supply cables around. Someone should tell him that the Romanian people don’t all sound like Dracula, and probably don’t like being stereotyped.

Doh! A floppy connector. One can only hope it’s off on its own little adapter because I hate those things with a passion.

Black. Lead-free paint. Single 120mm silent fan. Weight. Noise level. Operating temperature. You’ve got to love SilverStone… they always make sure you have all possible information on their units short of having the engineer come to your house in person for a lecture on how power supplies work.

It’s “open the box” time here in the lab. It’s also “oh God, why am I running two high power halogen work lights inside when it’s already over thirty degrees outside” time. Does anyone have any liquid nitrogen? I’m pretty sure my entire body is on fire right now.

Within the box, I found a power supply with a “this unit runs fanless” warning sash on it, some modular cables, two sets of screws, two manuals, an adapter plate, and a power cord. SilverStone looks to have spared no expense with the accessories.

The manuals are the usual two novel SilverStone affair, leaving absolutely nothing up to guesswork. The installation manual is the same one that’s come with most of my other SilverStones, so we’ll skip trying to get it into the scanner today. This is the spec manual, which is as complete as you could ever ask for.

The adapter plate allows you to mount both the power supply upwards or downwards within it, thanks to the extra screw holes in the power supply, but you can mount the adapter itself upwards or downwards if you wish thanks to its own double set of mounting holes. Doesn’t get much more flexible than that.
