Cooler Master Silent Pro Platinum 1000W Power Supply

The 7V rail. We first saw such a beast in October of last year, when Cooler Master released the way cool Silent Pro Hybrid unit that came with its own standalone fan controller. Today, the 7V fan only rail makes its reappearance in another Cooler Master unit, the Silent Pro Platinum. This is an updated 1kW unit with Platinum efficiency but is lacking the separate fan controller the Hybrid unit came with. Let’s find out what it’s like.

It’s been fascinating to see the progression of the 80 Plus program. First, we just had the standard certification, where units had to be above 80% efficiency between 20-100% loads. Manufacturers were quick to start cranking out units that adhered to this new certification. Then came Bronze, Silver, and Gold. Once again, power supply companies jumped at the chance to increase their market share by becoming more efficient.

Then, Platinum came along, and things started getting a little more difficult for the engineering staff. Now, we were talking efficiency levels so high, that one little design mistake meant slipping back to the Gold level. But it still didn’t stop units from popping up like boxelder bugs at my house, and we’re now at the point that even huge 1475W units are able to hit the target. And so, we are on the verge of seeing yet another 80 Plus certification level come into play: Titanium. That one is currently only used for 230V power supplies and requires units to be above 90% at everything above the 10% load level.

But for now, down at the 115V level, Platinum is still the top of the list. Nearly every power supply company out there has one or two units at this level now, and more are joining the list every day. Cooler Master is looking to throw their hat into the ring with the Silent Pro Platinum, so that’s what I’ll be looking at today.

The box for this unit is refreshingly devoid of major marketing, but there is still some to talk about. Let’s put the camera to work.

There you have it – the extent of the marketing bullet points on the box. Single 12V rail, 135mm fan, modular, Platinum. Oh, and a 7V rail. This unit claims to be the world’s first but methinks Cooler Master forgot to check their own lineup when they came up with this idea. The Silent Pro Hybrid was first. That one even came with a dedicated fan controller.

Also on the back of the box are some fancy graphs. This one shows the fan speed and voltage curves.

And this one shows the efficiency curve. You know, Platinum is a hard target to hit. Maybe this unit can do it, maybe it can’t. Load testing should answer that question, though, don’t you think?

For more information, see the website. I find it interesting that Cooler Master still has their own UL certification number, rather than using the one from their manufacturing partners. That costs money. A lot of it.

The rest of the box is nothing too special, but not bad looking at all.

There’s a table with some more specifications and the connector count here, as well as the output specifications.

More box here. Let’s unpack it now.

Looks like we get a box within a box. Let’s open this one up.
