Introduction and Features

The Strider Gold Evolution 1000W PSU is a second generation unit that is rated for 1,000W, is 80 Plus Gold certified and features all modular cables; including dual EPS connectors and six PCI-E connectors.

SilverStone’s new Strider Gold Evolution series power supplies include four models: 750W, 850W, 1000W and 1200W, which are based on the original Strider Gold series. SilverStone engineers have tweaked the design to improve both efficiency and performance and they replaced the original fan with a SilverStone Air Penetrator fan with fluid dynamic bearings to make it even quieter. The Strider Gold ST1000-G Evolution that we have up for review today is rated for 1000W DC output and is 80 Plus Gold certified. It comes with a full compliment of all modular cables, including dual EPS connectors and six PCI-E connectors for multiple high-end graphics adapter support. SilverStone also includes one of their new 140mm magnetic fan filters to help reduce dust buildup inside your PC.

Here is what SilverStone has to say about their new Strider Gold Evolution 1000W power supply:

“To make great power supplies even better, SilverStone engineers delved into the details with the Strider Gold series. In order to reduce the already low noise generated by the Strider Gold, they replaced the fan with SilverStone’s own Air Penetrator, which has superb cooling ability and is equipped with fluid dynamic bearings. This allowed for reprogramming of the fan controller to enable lower fan speed at any given loading condition compared to the predecessor. Various components were also re-tested and replaced with newer versions for minor boost in efficiency and performance. An excellent FF141 fan filter with magnets is even included in the package for use to reduce dust buildup.

With the fan and component upgrades, the Strider Gold Evolution series will again encompass wattage range from 750W to 1200W with 80 PLUS Gold level efficiency, ±3% voltage regulation, low ripple & noise, and high amperage single +12V rail as its main features. For discerning users looking to get a top-notch power supply with all features covered and more, this is the perfect solution.”

Testing Methodology

Establishing an accurate load is critical to testing and evaluating a PC power supply. PCPerspective’s power supply test bench can place a precise 2,000 watt DC load on the PSU under test. Each power supply is tested under controlled, real-world conditions up to its maximum rated load (at 40ºC), using both 115 VAC and 240 VAC line voltage. Our current suite of tests includes:

• DC Load Regulation
• DC Line Regulation
• DC Cross-load (unbalanced load)
• AC Ripple and Noise
• Power Factor
• Efficiency
• Differential Temperature
• Noise

The SilverStone Strider Gold 1000W power supply was evaluated on both features and performance. A full range of equipment was used to test the power supply under controlled load conditions.

• (2) CSI3710A Programmable DC load (+3.3V and +5V outputs)
• (4) CSI3711A Programmable DC load (+12V1, +12V2, +12V3, and +12V4)
• (2) 200W Precision resistor load bank (+12V5 and +12V6)
• Switchable precision resistor load bank (-12V and +5VSB)
• Extech MultiMaster MM570 digital multimeter (Accuracy ±0.02%)
• Extech 380803 Power Analyzer (Accuracy ±0.5% of full scale)
• DS1M12 "StingRay" digital oscilloscope (20M S/s with 12 Bit ADC)
• Powerstat Variable Autotransformer, 1.4 KVA, 0-140 VAC
• Extech Model 407738 digital sound level meter (Accuracy ±1.5 dB)
• Custom PC60 enclosure to simulate real-world operating conditions
