Introduction
We have recently seen the newest High Power (Sirtec / Sirfa) 80 PLUS Gold (@115 V) platform in the Silverstone Strider Gold S/Gold V2.0 550 W unit. This time we have another version of this platform in the SilentiumPC Supremo M1 Gold 550 W. This unit is sold by a Polish company called SilentiumPC which has been selling cases, coolers and similar devices for some time already, and seek to grab a share of the Power Supply market in Europe. Who knows, their products may appear later on Asian, American or Australian markets. This is their second entry into the PSU market after their original 700W Platinum flagship product.
This unit comes with semi-modular cabling (Main ATX and ATX 12 V are fixed) and a somewhat larger chassis than the Strider Gold S; as the Supremo M1 uses a larger 135mm fan. Otherwise, it looks like pretty much the same unit but it is priced at only 2300 CZK with a three-year local warranty (SilentiumPC promises a full 5 year warranty if the unit is shipped to them), some 300 CZK lower than the Strider Gold S, thus it is targeted towards the high-end market, albeit just barely so. It has the same 45.9A/550.8W main +12 V rail (hehe, the same funny sticker, for which I’ll add an extra half-point as well for the Supremo) with DC-DC modules for +3.3/+5 V.
Each rail is able to provide 20 A, or 105 W combined, pretty much like the Strider, and the rest of the specs are the same too. Note how the full range of protections are all listed on the sticker (OCP, OTP, SCP, OPP, OVP, UVP). The unit has four connectors for SATA / Molex / Berg cables and two PCIe peripheral connectors.
Packaging and accessories
The (mostly white) printed cardboard box lists the main features on the front, some of them twice just to be sure I guess ☺. The unit inside sits in a piece of foam but has nothing to protect the top part. Hopefully it will survive a rough transport.
The rear side repeats the important information and adds a power distribution table with cable lengths. Fair enough.
The accessories include a power cord, all the modular cables, warranty list and manual (which occupies half of the warranty sheet), and some screws.
