Operation System Setting: CPU 500X8.5=>4250Mhz DARM DDR3 2000 CL8 7-6-20 1T In OCCT test, the dual CPU will be in full usage. The CPU voltage curve is a flat and straight line. 3.3V The voltage is between 3.2 and 3.22V. Voltage change % is about 0.625%. 5V The voltage is between 4.85 and 4.87V. Voltage change % is about 0.4%. 12V The voltage is between 11.71 and 11.78 V. Voltage change % is about 0.6%. The Voltage numbers above are tested by motherboards. Different motherboards will show little difference in the 3.3V/5V/12V test. I won’t say this voltage numbers are most correct. If you want to get the real voltage number, please use the electronic measurement. OCCT only can take the high-load operation, the variance from the voltage rise or drop only for reference. According to this test platform, here is the result: I use the results from Power Angle as reference. Enter the operation system condition (269W) Use OCCT test with dual core CPU in full load (351W) In previous test, I use Q9950 OC 3.7G + 9800GTX, quad cores in full load. The result is 309W. Even adding high level VGA and quad cores, in OCCT test, the result is always below 420W. For a higher Waltz PSU, OCCT test could not show its biggest performance. 3DMARK2005-489W 3DMARK2005 is the most waltz-consuming 3DMARK software, so we use this software to match with 4870X2 for performance test. OCCT + 3DMARK2006-523W The result for the OS platform with 3DMARK2005 Test Conclusion of be quiet! Dark Power Pro 1200W Advantages: 1.High quality package and clear instruction manual 2.High Efficiency Certification, such as Active PFC and 80 PLUS. Wires are long and thick enough with small instruction tag. 3.With 6 PCI-E/ 11 SATA Connectors. Sufficient support for 3 Way VGA or Server with multiple HDD. 4.Great voltage performance in 3.3V/5V/12V test. 5.PSU temperature is low in operation. Equip with 14cm fan to lower the operation noise. 6.18 months for free renew. 3 years door-to door shipping, and 5 years warranty. Disadvantages: 1.The small tags on wires drop easily. 2.Need to enhance its distribution channels in Asia Performance ★★★★★★★★★☆ Components ★★★★★★★★☆☆ Outlook ★★★★★★★★☆☆ C/P ratio ★★★★★★★☆☆☆ 14cm FDB-fan could adjust its speed according to temperature and power consume. From 0 to 100% power consuming, the noise goes from 18 to 30 dB. Seeing the extremely quiet fan, I really admire this brand name. Some people might think higher Waltz PSU will consume more power. Actually, this is wrong. Power consume depends on your PC and peripheral. High Waltz PSU only provides higher power quota for usage, but won’t consume more electricity. If your PC only consumes 350W, for this Dark Power Pro 1200W, it will only provide 350W to your PC. When you need higher power, it could support you till 1200W. Especially this high-level PSU with 80 PLUS and Active PFC certification, it could save more electricity by its high efficiency. Now be quiet! develops more products in its two series. From its brand requirement in quality and quietness, we could have one more choice in the high-level PSU. Moreover, it does provide a really complete warranty. If be quiet! could make the price more friendly, its revenue will raise a lot. |
