SilentiumPC 700W Supremo M1 Has 80-Plus Platinum Certificate

SilentiumPC has revealed a PSU with a fan that will only spin up when necessary.

SilentiumPC has announced a new power supply – the Supremo M1 Platinum 700W. This unit is, as the name indicates, a power supply capable of delivering up to 700 W of power and carries an 80 Plus Platinum efficiency certificate.

The unit is built by High Power Technology, which has built the PSU with a single 12 V rail that can push up to 58 A of current. Included cabling consists of a 24-pin ATX connector, a 4+4 pin EPS connector, along with four 6+2 pin PCI-Express power connectors, a single Berg (Floppy) connector, four Molex connectors, and 10 SATA power connectors. The ATX and EPS connectors are fixed to the PSU, while the remainder of the cables are modular.

Due to having an 80 Plus Platinum efficiency rating, the unit does not generate a lot of heat. This allows the 135 mm fan that is installed to only have to spin up when the unit reaches over 300 W of power draw. Below that the fan simply doesn't move, allowing for whisper quiet operation. When the fan does spin up, it'll spin at only about 600 RPM at first, slowly spinning faster as the load increases, reaching up to 1000 RPM.

Pricing for the unit is set at $129, though street prices may vary.

    excellent, love these hybrid fan solutions and platinum grade psu.
    just hope they have no electrical noise......

    The fan idea is nothing new. I've got a PC Power and Cooling PSU which has a fan that only turns on at about 400W or so. PC Power and Cooling just went under in the OCZ takeover, but now EVGA picked up the Super Flower OEM products that PCP&C were selling. Check out the SuperNOVA series from EVGA. Best PSUs on the market.

    There's nothing special about this PSU, and being at 700W its in a weird spot of having way to much power for your system without having enough for sli/crossfire expandability.

    Yep, I've heard about this for years. While it deserves a mention, it shouldn't be that much of a unique selling point since this is pretty common now. Just say, and it comes with fanless operation below XXX Watts.

    Very common to have this fan feature, although this PSU seems like such a nice piece of kit!

    It does seem like a decent PSU.

    Wait, what? Anand's test rig with 780ti's peaked at 652 watts from the wall. Assuming they used a 90% efficient power supply that means 587 watts were being supplied by the PSU to the machine. Even if you assume that every single watt the machine was being delivered was on the 12v line it would mean 48.9 amps, where this rig is rated at 58 (so 85% capacity, which is pushing it a little but not unheard of, and the PC would rarely be drawing that amount for any length of time in most cases).

    That leaves a ton of room for plenty of crossfire/SLI configurations.

    not to mention usually platinum power supplies (at least mine) can go over their spec, they just lose efficiency

    What is most important and they don't often say (for most brands) is what the rating is at different levels of power consumption. Maybe it peaks at 300, who knows.

    Always happy to see platinum power supplies though.

    80Plus Platinum Means it's 90% at 20% usage, 92% at 50%, and 89% at 100% (115v). A power supply usually peaks somewhere in the 50-70% range, but the difference between 92% and 89% is only about 20 watts on a 700 watt load, so it's not like it matters all that much.
