Efficiency is Platinum and the unit uses several native and modular cables. It is also equipped with all available protection features and utilizes a semi-passive operation where the fan doesn't spin up at low loads, which results in a dead-silent unit until the load picks up. The Supremo is also Haswell ready since it uses DC-DC converters to generate the minor rails.

Dimensions are normal for a 700 W PSU, and the same applies to its weight. However, the warranty looks short for a premium unit and should at least be five years long. Its price is also on the high side since Platinum PSUs are still expensive. The Supremo PSU ultimately looks really good on papers and we are anxious to figure out how it performs by putting it on our test bench and running it through our tests.

SilentiumPC Supremo M1-700 Power Specs
Max. Power20A20A58A3A0.5A
Total Max. Power700W (800W Peak)
The single +12V rail is powerful enough since it can deliver up to 58 A, and the same applies to the minor rails which can deliver up to 120 W combined. The 5VSB rail is a little stronger than the average.

This PSU has two EPS connectors, which is as it should be since its capacity is 700 W, and comes with four PCIe connectors, an adequate number for a mid-capacity PSU that can easily support two strong VGAs with two PCIe sockets each. The Supremo M1 comes with a ton of SATA connectors, which is unusual for units of similar capacity. There are also enough Molex connectors to cover most situations.

All connectors are installed on cables that are long enough, including the main ATX and the first EPS cables that can give extra-large cables the hardest time. The modular cables are flat and stealth, making cable management tasks much easier, while nearly all native cables are pretty rigid, which will make cable routing difficult. The reason behind their decreased flexibility is the use of thicker 16AWG gauges for lower voltage drops at higher loads; the modular and native PCIe cables use standard 18AWG wires.

We have nothing to comment on when it comes to the PSU's power distribution because it features a single +12V rail.
