In this part of the video, the presenter introduces a review of five popular power supplies in the $60 to $80 price range for budget to mid-range PC builds. They emphasize the use of comparative benchmarks to help viewers decide on the best option. The selected power supplies were based on user reviews and popularity rankings. Criteria include efficiency, voltage ripple, and protection mechanisms. The presenter also invites suggestions for additional power supplies to review in this price range.
00:03:00
In this part of the video, the presenter discusses the goal of the power supply reviews, which is to create comparative charts for easier performance evaluation. They aim to focus on efficiency, protections, regulation, and ripple in the power supplies ranging from 550 to 700 watts (2015-2021). The video compares two Corsair power supplies, CX650 and CX650M, highlighting differences in price, warranty, topology, and cable features. The CX650 is non-modular with fully sleeved cables and two dedicated PCIe cables. On the other hand, the CX650M is modular and slightly more expensive. The presenter emphasizes the importance of these distinctions for potential buyers.
00:06:00
In this segment of the video, the speaker discusses different power supplies, focusing on the CX650M, EVGA 700 BQ, Fractal Ion Gold, and Seasonic units. The main differences highlighted are the CX650M’s double forward topology, the EVGA unit’s DC to DC regulation on the secondary side, the Fractal Ion Gold’s seven-year warranty, shorter ATX cable, and 16 gauge AC power cable. The Fractal unit also features a 140mm fan while the others use 120mm fans. Special mention is made of the varying PCIe cable setups among the power supplies.
00:09:00
In this segment of the video, the focus is on the GM 650, also known as the SSR 650 FM power supply. It is highlighted as having a historical average price of $83, with a warranty and supplied by Csonic. The video discusses objective testing using specialized equipment to analyze power supply quality and safety features such as efficiency, voltage ripple stability, power factor, and protection features like over current and short circuit protection. Efficiency at different loads is measured, with the ion gold 550W being the most efficient in the 40% load category. The video also touches on the importance of efficiency, showing variations between different power supplies and emphasizing the impact of single digit percentage changes, especially at higher wattages.
00:12:00
In this segment of the video, the focus is on comparing power supplies based on 12 volt regulation and ripple measurements. The video discusses the importance of stable power output in powering components like CPUs and GPUs. The SeaSonic GM 650 is highlighted as the most stable unit with only 0.2% variation, while the CX650M exceeded 1% variation. Ripple measurements are discussed with the Fractal Ion Gold 550W being the top performer with a peak-to-peak measurement below 30 millivolts, meeting the standard. The EVGA unit leads in lower cost options with a measurement of 19.2 millivolts peak-to-peak. Consistent power output and low ripple are crucial for maintaining system stability and health.
00:15:00
In this segment of the video, the speaker discusses power factor measurements and their significance in power supplies. They explain that a power factor close to unity is ideal as it indicates efficient energy usage, lower electricity costs, and reduced heat generation. The video compares power factors of different power supplies at varying loads, noting differences in performance. The Fractal Design power supply improves its power factor at higher loads, while EVGA’s unit excels at lower loads. The importance of power factor efficiency is emphasized, with considerations for both high and low load scenarios. Lastly, the video covers the testing of protection features in power supplies, highlighting short circuit, over current, and over power protection tests conducted on various units. While most units demonstrated proper protection triggering, the Fractal unit faced a potential limitation related to the 5-volt standby rail.
00:18:00
In this part of the video, the speaker discusses the importance of power supply output current not exceeding 140 percent of its maximum rated output to avoid thermal runaway and unsafe scenarios. Testing revealed that the 5vsb rail often hits trigger points of 180 and greater, indicating a need to further understand this area. Cross load testing involves heavy loading of one output set to observe its effect on other rails. Results showed good regulation of voltages, with minimal variance from the specified values when applying heavy loads, particularly with the Corsair CX650 and Fractal Design power supplies standing out for maintaining stable outputs.
00:21:00
In this segment of the video, five power supplies are discussed. The Fractal Ion 550W is suitable for most gaming PCs but may struggle with lower loads. The SeaSonic power supply performed well overall and stayed near the top in important tests. The Corsair CX650 offers good value with a 650W output, exceeding the Fractal Ion. Finally, the EVGA 700W power supply stands out for its wattage capacity and strong performance in voltage regulation and ripple tests. It is considered a tough competitor in its price range. The video concludes by mentioning the need to explore newer power supply options.
00:24:00
