Cooler Master Silent Pro Hybrid 850 Watt PSU review - Load testing the PSU

Load testing the PSU

Testing a power supple these days always is a bit of a challenge at hand. I mean without professional load testers it's pretty hard to stress a power supply of this class and actually measure its behavior.

CM Silent Pro hybrid

Our first check is with a simple cheapo power supply tester, we monitor voltages quickly and check if all rails are working. All good here.

The test setup

So for our load test here's what we did. We emulate real world usage. We take an Intel P55 based Quad SLI compatible motherboard, armed it with a GeForce GTX 590 card (has two GPUs per card).

We combined the P55 motherboard with a Core i7 870 processor overclocked to 3.8 GHz. The system, well have a look:

These are the components used:

  • eVGA P55 Classified SLI motherboard (has fairly high power consumption and an NF200 chip)
  • Core i7 870 (overclocked to 3800 GHz) 20x190 BLCK at 1.4 Volts
  • 1x GeForce GTX 590 primary (2 GPUs)
  • 4 GB Memory DDR3 @ 1520 MHz
  • OCZ Vertex 2 SDD x1

Now with a setup like this, many years ago we'd reach 550 Watts power consumption as maximum. But with power supplies getting more and more efficient these days, even that proves to be a harder task to accomplish.

So above our graphics card setup. Now on the software side of things it is time to give the PC a decent beating. Remember our focus remains PSU efficiency.

We now take some other power supplies: 

CM Silent Pro hybrid 

Looking at efficiency is really simple, we apply the same load on several power supplies, from old to new. We look at the powered off status, windows IDLE status, productivity mode (we stress the CPUs) and during gaming. The lower the Wattage, the more efficient.

The best indicator for good efficient power consumption is by looking at the game test. As you can see the Silent PRO consumes a fair amount of power, but there are two Platinum certified products in there. Mind you that a PSU is most efficient at 50% load. Stress it higher and your efficiency will drop.

This Gold Certified PSU seems to get really close to Platinum standards, very good.

Powered off the PSU consumed roughly 1.6 Watt.

With the computer powered on and in absolute IDLE we can notice interesting differences , but it's all real close to each other.
