BFG Tech PC System 1,000W Power Supply Review
Features and Specifications
BFG Technology is probably best known for their high-end video cards, but recently BFG has come out with their own line of motherboards and added a couple high-output power supplies to their product offering. BFG Tech's power supply lineup includes six models ranging in output capacity from 530W all the way up to 1,000 watts (1kW). The new 1kW power supply is targeted towards power users and is backed by BFG's Life Time warranty.<?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" />
BFG Tech 1kW PSU Key Features:
- Up to 1,000 watt power output
- ATX12V v2.2 and EPS12V 2.91 support
- Quad +12V outputs (up to 75A combined +12V)
- Dual 80mm cooling fans
- Four PCI-e 6-pin connectors (nVIDIA SLI Ready)
- Active PFC with Universal AC line input
- Black mesh sleeved cables
- Life Time warranty
Name Plate data:
Interestingly, there seems to be a discrepancy under the +5VSB listing. The maximum combined wattage of -12V and +5VSB (20W) shouldn't be less than the rating of the +5VSB output by itself (32.5W)?
BFG Tech 1kW PSU Specifications:
In addition to the power supply the bright green box includes a power cord, mounting screws, Velcro cable ties, and a very brief Installation sheet.
The BFG Tech 1kW 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. In addition to measuring the power going in and coming out I looked at voltage regulation, AC ripple, sound level, efficiency and cost. Here is a list of the equipment used during testing.
- FLUKE 87-III True RMS digital multimeter (Accuracy Â±0.05%)
- Extech 380803 Power Analyzer (Accuracy Â±0.5% of full scale)
- <?xml:namespace prefix = st1 ns = "urn:schemas-microsoft-com:office:smarttags" />
V-650F 60 MHz dual trace oscilloscope (Accuracy Â±3%) Hitachi
- Powerstat Variable Autotransformer, 1.4 KVA, 0-140 VAC
- FLUKE 52-II digital thermometer (Accuracy Â±0.3ÂºC/0.5ÂºF)
- Extech Model 407736 digital sound level meter (Accuracy Â±1.5 dB)
- AccuLab V1-10kg digital balance (Accuracy Â±1g)
- Homemade PSU load tester — selectable loads (up to 470W)
- (2) CSI3710A Programmable DC load (up to 150W each)
- (2) CSI3711A Programmable DC load (up to 300W each)
Establishing a controlled load is critical to testing and evaluating a PC power supply. In addition to my own home-made load tester, I used four programmable DC loads for greater flexibility and accuracy. This new combination can place up 1,400 watt load on the unit being tested.
