SilentiumPC Supremo M1 Gold 550W Power Supply

Folks, we have a new subject to study today, and it comes all the way from Poland. The SilentiumPC Supremo M1 Gold 550W promises to be a good, stable unit that won’t break the bank while still giving you such things as semi-modularity and high efficiency.

I always have a blast looking at units from manufacturers I’ve never seen before. Some of them, like the Ikonik Vulcan 1200 watt unit, turn out to be awesome. Others, like the Hercules HRC512F, turn out to be rig destroying fire hazards. Either way, I’m seeing something new and it’s usually interesting.

Today’s review sample comes to us from Poland and a company called SilentiumPC. We’re looking at their Supremo M1 Gold 550W model, which is just about the best you can get from them in something that’s not 80 Plus Platinum.

A lot of the box marketing is found right on the front panel. It’s quiet, it uses VRM technology to pull the minor rails off one big 12V rail, it has Japanese capacitors, it has polymer capacitors, all the usual stuff to assist in parting you with some cash. We’re going to find out soon enough if it’s deserving of said cash in a little bit.

But first, here’s the back of the box with a full list of protection circuits. Looks pretty good to me… it even has overtemp protection in case I can’t find any maximum temp data and end up shutting it down in the hot box.

There’s not too much worth noting about this panel of the unit, except for the lack of a UL mark. That said, this is not a big deal when your primary business environment is not North America.

Had enough marketing yet? No? Good, because the box is only too happy to repeat itself on this side panel. Hmm… looks like only the primary side capacitor comes from Japan. We’ll find out for sure later.

Meantime, how about we get this puppy out of the box?

Within the cardboard shell, I found a power supply, some documentation, some modular cables, a few screws, and a Shuko style power cord.

The documentation is a little light for a higher-end product like this one. You get the above Polish warranty term sheet, and…

what has to be one of the most lackluster user guides that I have ever seen. It’s better than no guide at all, but there are no specs whatsoever. In fact, I don’t even see a maximum operating temperature on the website either, so I’m going to have to shoot for fifty degrees in the hot box.
