Thanks to its super compact SFX size, the Revolt SFX is ideal for small form factor chassis. This PSU boasts a length of only 100mm, freeing up space for cable management and airflow. Both of which are essential in small PC cases. FULLY MODULAR Top-end build quality with low ripple noise. All ripples are lower than 30 mV on +12V, +5V or +3.3V from 0% to 100% load to ensure a stable operation and keep your performance-critical components to function reliably for longer. Thermaltake, the leading PC DIY premium brand for Case, Cooling, Gaming peripherals, and enthusiast memory solutions, is excited to announce their latest addition to the PSU lineups, the Toughpower SFX series, which is designed to meet ATX 3.0 standards and is PCIe Gen 5.0 ready. Designed to run with the RTX 40-series series graphics cards and the latest Intel CPUs, the Toughpower series comes with an SFX-sized form factor and fits in the mainstream ATX and ITX cases, which is essential for users looking to put together a smaller-footprint build. The following are the Toughpower SFX series's dimension for your reference. 750 W & 850 W: 125 mm (W)x63.5 mm (H)x100 mm (D); 1000 W: 125 mm (W)x63.5 mm (H)x126 mm (D).

Seasonic recently released an SFX PSU with 750 W maximum power output in an attempt to dethrone the mighty Corsair SF750 Platinum, which is the best currently available SFX PSU offering. A significant advantage the SPX-750 has over the SF750 is the long 10-year warranty, as the Corsair offers 7 years for its flagship SFX offering. In my opinion, anything above five years is unreasonable when it comes to power supplies, which are highly dependent on the quality of the mains grid, and external factors can affect the latter (e.g., thunderbolts). If a power surge or brownout damages your PSU, the warranty won't cover it, which is reasonable because PSU manufacturers are not responsible for the power grid's quality.

ZERO RPM FAN MODE

Efficiency is excellent, peaking at just over 94% around 50% load. At full load the power supply maintains a 92.7% efficiency level, which is impressive. Toughpower SFX series saves energy through its high energy efficiency up to 90% and is certified to 80 PLUS Gold. The series has been optimized to work with all generations of Intel's processors to achieve maximum energy saving.

It is likely if you have this supply in your system and you are doing general work it won't make a noise at all. Under higher load situations, the fan will spin, but until you are close to 80% load, it won't really make its presence known. At full load, the fan is quite noisy but we would expect this – after all it is still only 90mm in diameter. Corsair are using Great Wall as the partner for this particular power supply design. The layout, construction and overall design is very similar to the SF600 model in the range which we had a look at before. All of the electrolytic capacitors inside are Japanese made, which is good to see – especially as Corsair claim this in their literature. The primary bulk capacitor is made by Nippon Chemi Con rated for 470uF, 420C and 105C. The other side of the power supply shows the modular bay- clearly named and split into sections to ease installation. Individually Sleeved, Fully Modular Cables: Flexible paracord sleeved cables make routing and cable management incredibly easy. We like the box artwork for this power supply, all the key points are listed along the bottom at the front of the box, along with a quality high resolution image in the middle.We are happy to see Corsair have adopted all Japanese capacitors in both primary and secondary stages to offer long term reliability and stable operation under heavy load conditions. The primary bulk capacitor is by Japanese manufacturer Nippon Chemi Con and is rated 105c.

Toughpower SFX series comes with a 16-pin connector to offer powerful and stable performance allowing the PSU to natively run next-generation GPUs. For the cases, the out-of-the-box fan setup is used, connected to the motherboard, with the board adjusting fan speed automatically. This puts the onus of noise and performance on the case manufacturers and motivates them to actually care about thermal performance instead of simply using active cooling as a marketing bulletin point. We tested this power supply and it was not only able to deliver a continuous 750W, but it almost delivered 790W before it shut off safely. This is very reassuring to see and we recorded a long run at 770W load without any problems or potential shut down issues occurring.

The unit passes our Cross Load testing without any problems. When hit with 60 AMPS the +12V rail held at 11.88. Not a very realistic situation in real life, but a good sign that the design works well. Featuring a 92 mm fluid dynamic bearing fan (120 mm in 1000 W) to guarantee superior cooling performance.Powerful single +12V rail can properly deliver the power you need for the best compatibility. The use of LLC and DC to DC circuit design provides very stable operation and enhanced voltage regulation. This Phanteks SFX PSU is 80 Plus Platinum certified, achieving 92% efficiency at 50% system load. Not only is this power supply efficient, the Revolt SFX is equipped with a silent zero RPM mode. This means when the PSU is below 30% system load the high quality 92mm Fluid Dynamic Bearing fan is inactive, enabling ultimate silence. Phanteks Revolt SFX 750W 80 Plus Platinum PSU Specifications: PSU Dimensions (L x W x H) Technically there is little, if anything we can fault. Load Regulation is first class, and the unit meets Platinum efficiency levels without a hiccup. The unit design produces tight control over AC ripple mV and we recorded stellar results, even under full load conditions. The Corsair SF750 SFX Platinum power supply is another tour de force showcase from Corsair. They are incredibly strong right now in the small form factor sector and the high output SF750 reinforces their growing status.

Additionally, as we would expect in this price point, the SF750 is a fully modular power supply featuring very high Platinum efficiency certification. This is a standard sized SFX chassis too – its not one of the extended length versions we see from time to time from other companies. Our test setup focuses on four components small enough to fit into every chassis format. This allows us to compare the impact case size and cooling have on a modern system. Each of the four measured components is connected to a REED Instruments SD-947 Data Logging Thermometer with K-Type sensors that have been placed as closely as possible to the benchmarked areas of the CPU, GPU, M.2 SSD, and motherboard chipset. A fifth sensor is used to monitor the room temperature for an accurate delta T result. While the data provides us an accuracy of one decimal point, it is still dependent on human placement of the sensor as well as small variance in things like automatic disk activity in windows for example. The systems is air-gapped, so that no automatic software updates can trigger an unwanted workload on any of the components. There are a total of eight individually sleeved modular cables in the box and there are plenty of connectors to cater for the majority of enthusiast system builds. We can see that the 750W version also ships with 2 4+4 Pin EPX/ATX12V connectors, a great addition to see. The cables are quite short, intentionally, to ensure system builders are not dealing with very long cables inside a small form factor case. It is worth noting this however if, for some reason you are intend on using this power supply inside a larger chassis. Other compromises include a rifle-bearing fan, a semi-modular PSU design, and a relatively short five-year warranty. None of these are deal-breakers, but they definitely reflect the BM2’s budget price. Bronze efficiency isn’t great either, but acceptable in this price range. The voltage regulation, more strict than Intel's standard +5%,-7% for major rails and ±10% for -12 V, is set to no more than ±2% for major rails, providing steady clean power through exceptional voltage stability.Primary side: Half-Bridge & LLC Resonant Controller Secondary side: Synchronous Rectification & DC-DC converters As the power consumption of graphics cards has increased, so has their demand for power. The SFX series is designed to support NVIDIA and AMD graphics cards, ready to supply the graphics card according to their different ways of connections. With its super compact SFX form-factor combined with high power output, the Revolt SFX is the perfect match for small form-factor chassis. Its length of only 100 mm frees up space for easier cable management and improves the overall building process. An Unprecedented 750 Watt SFX PSU: Harness 750 continuous watts in SFX form, perfect for the most power-dense small-form-factor PCs. We take the issue of noise very seriously at KitGuru and this is why we have built a special home brew system as a reference point when we test noise levels of various components. Why do this? Well this means we can eliminate secondary noise pollution in the test room and concentrate on components we are testing. It also brings us slightly closer to industry standards, such as DIN 45635.
