We had opportunity to check the SilverStone
ST85F-G Evolution 850W power supply and found that it provides the effective
power adjustment. For example, ST85F-G Evolution is designed to meet the 80
PLUS Gold standard by providing the efficiency from 88% to 91% under load from
20% to 100%.
ST85F-G Evolution is designed with a rail
+12 V can be up to 70A (840W). SilverStone said PSU had the ability to maintain
voltage regulation +/-3%, for providing stable electrical to the hungry power
components. +3.3V rail supports up to 22A, +5V rail supports 25A. In cables,
ST85F-G Evolution is completely disassembled, and those have small chassis or
want to reduce cable can invest in the short cables of SilverStone PP05.
You will have support for SLI and CrossFire
GPUs 2-way configurations with 4 PCI-E connectors (2 6+2-pin connectors and 2
6-pin connectors). SilverStone designs PCI-E connectors with the 2200uF
capacitors to reduce noise during big load changes. SilverStone also said the
2200uF capacitors could improve ripple voltage stability. For future CPU power
demand, SilverStone gives you 2 4+4-pin CPU +12 V latch connectors. One of
these cables is nearly 30 inches in length, great for those need to run cable
along the chassis; additional length gives you extra freedom to take the cable
behind the motherboard tray. To supply power for accessories, there are eight
SATA connectors and 6 Molex connectors.
To check the source, we installed it on a
running processor system of Intel Core i7-990X on the DX58SO2 motherboard. With
graphics power, we use 2 ZOTAC GeForce GTX 580 graphics cards in SLI. We also
run POV-Ray 3.7 Beta and Aliens vs Predator to maximize the load on ST85F-G
Evolution. Under this maximum load, it has maintained very well, creating the
767 maximum voltage and .975 power factor.
Those who are looking for the stable,
reliable source will love the performance and special features of ST85F-G
Evolution. People who love overclocking will like the flexibility of the
removable PSU system, as well as compatibility with the short cables of
SilverStone option. Either way, ST85F-G Evolution is a winner.
