Sparkle is mainly known for their video cards, and as we have seen, they tend to deliver. Power supplies might seem to be an odd place to branch off into at first, but it makes sense given that the graphics card is becoming one of the largest single power draws in a modern gaming system.
High-end PCs use a lot of power, and that power has to be tightly regulated. Voltage spikes, dips and fluctuations can cause malfunctions, or even dead components. It’s no exaggeration to say that your PC lives or dies by the quality of the power it receives. Over the years I’ve seen dozens, if not hundreds of systems with fried circuit boards, blown capacitors and even cooked-off wire insulation, all caused by sub-standard power supplies.
Today, we’ll be taking a look at a power supply that aims to be as far away from substandard as possible: Sparkle’s Gold Class SCC-850AF. Let’s see if that sparkle comes from the luster of the finish, or the fizzling sparks of dying circuitry.
Sparkle has never been big on exuberant self-promotion, preferring instead to let the products speak for themselves—an approach I can always appreciate. Here then, is a list of features to get that discussion started:
- 850W Modular Power Supply
- 80 Plus Gold Certified
- Double Ball Bearing Fan
- All connector AU coating to keep Ultra high efficiency
- Full Thermal Control with super silent fan
- 12V peak at 80A
- Temperature control design mode
- Active PFC design
- Keep PSU fan running for 5-10 seconds after shut down to dissipate the remaining system heat and prolonging system lifetime.
- Ultra-quiet 13.9cm Fan with intelligent RPM control guarantees cool performance and silent operation.
- 99.9% 12V Power
- SYNC Transformer Array
- Double main electrolytic capacitors
- DC to DC circuitry design with solid capacitors
- Forward Safe Guard Circuitry Design
- Dual Layer main PCB 1.6mm thickness
- Quintuple 12V Rails
- 100A Mosfet 12V Rectifiers
- 20k µF low ESR secondary 105°C electrolytic capacitors
- Triple AC EMC Filtering stage
- Dual capacitors design to protect system safety when sudden shut down
One feature that stands out is the extended running of the cooling fan. As many cases use the power supply fan to help cool the rest of the system, letting it run for 5-10 seconds after the rest of the system has shut down helps to dissipate any remaining waste heat. If you’ve got a particularly hot-running system, this may well prolong the life of your components.

The thing to note here is the current rating on each rail: a guaranteed minimum of 16 amps on each of the five 12 volt rails. This power supply is clearly designed for power-hungry components.
