Cooler Master Silent Pro Hybrid 850W Power Supply Review

Allan 'Zardon' Campbell March 7, 2012 Featured Announcement, Power Supplies

The Cooler Master fan is actually made by Young Lin Tech Co Ltd. We have seen this fan used in other Cooler Master power supplies, although this time Cooler Master have ‘branded' it with their own sticker. The fan is rated to 2,000 rpm, with an airflow of 82.41 CFM generating a maximum noise level of 37.98 dBa.

Cooler Master have partnered with Enhance for this specific design. They are using several rows of large heatsinks to cover the full length of the PCB. We would assume they are playing it safe by using large heatsinks to help ensure that the large fan can spin as slowly as possible, especially if a user lowers the fan rotation speed with manual settings.

The Silent Pro Hybrid 850W uses a single X and two Y Caps on the AC receptacle. There are two pairs of Y and X caps, an MOV, two CM chokes and a thermistor on the main PCB.

The design uses two primary capacitors rated 330 uF, 420V @ 105c.

The main transformer is a hybrid design combining the transformer and heatsink into a single entity. This should mean higher efficiency due to reduced temperatures and transformer size.

Quick question.

What on earth is up with the pricing on power supplies lately? £200+ for a 850W unit? companies need to realise that most people cant afford this.

I love Cooler Master. This is too rich for my blood. id aim for a bronze unit, those gold and platinum rated models are just way out of my price point.

The fan controller idea is interesting, but many people who want this kind of power supply will either already have one, or wont want it. paying extra for something they dont need IMO isn’t such a good move. it might work well in PR releases f or Coolermaster to say ‘first 7V etc!’ but the audience this is targeting might not appreciate the forced purchase at extra cost.
