On top of that, the built-in Smart Zero Fan (750 W&850 W: 92 mm; 1000 W: 120 mm) makes absolutely no noise at all when running under 30% load. The Toughpower SFX series features low ripple noise, strict voltage regulation, and extended hold-up time. Firstly, from 0% to 100% load, ripple noise produced from 12 V, 5 V, and 3.3 V are consistently under 30 mV, bringing extensive lifespan and overall superior protection for your system. Secondly, the Toughpower SFX series promises ±2% voltage regulation compared with Intel's standard +5%, -7%, and ±10% for -12 V. Last but not least, the 17 ms hold-up time will prevent your system from rebooting and makes sure the system still runs perfectly even with a brief interruption. SFX power supplies always have to make sacrifices in regards to fan noise, and thankfully Corsair have taken some clever steps forward to alleviate this potential headache. They have adopted a larger 90mm rifle (normally 80mm) bearing fan inside this supply, and thanks to Corsair's Zero RPM system, it does not spin at all under lower or even normal load situations.

Phanteks has just launched its all-new Evolv Shift XT expanding ITX chassis and Revolt SFX series power supplies. The Evolv Shift XT takes a fresh approach to small form factor builds with its adjustable height. Three configurations are possible depending on the amount of cooling you need or desire.

However, the good news is that most of Quiet PC’s PSUs implement a system known as Active PFC which involves some clever electronics. This means that their power factor (PF) can be as high as 0.94 or 94% (at full load), while harmful harmonic frequencies are reduced to well below legal requirements. So by using our products, you can be happy in the knowledge that you are doing your bit to save the planet! 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. The Evolv Shift XT’s innovative design allows the chassis to extend its height to tailor the cooling performance to your need. In “Compact” mode, the Evolv Shift XT can house systems with up to 324mm long 3-slot GPUs and 72mm tall CPU coolers that have direct access to fresh air. In “Air Boost” or “Liquid Cooled” mode, the height can be increased from 32mm to 60mm respectively for further hardware compatibilities like adding 2x 120/140mm fans (Air Boost) or a 240 AIO Liquid Cooler (Liquid Cooled) for the best possible performance. 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.

The Corsair SF750 is an SFX power supply – and not one of the many extended units we have seen in recent years – its only 63mm x 125mm x 100 mm (HxLxW). Electrolytics: 1x Nippon Chemi-Con (4-10,000 @ 105°C, KY), 2x Rubycon (3-6,000 @ 105°C, YXG) Polymers: Nippon Chemi-Con (G61B, G8, G84R, G84G, G85F), 6x Nichicon (LG) Oct 16th 2023 Thermaltake Unveils Its First Ever Bumblebee-Colored Product in The Tower 200 Mini Chassis Series (19) SF Series power supplies give you 80 PLUS Platinum efficiency, excellent electrical performance, and virtually silent operation in a SFX form factor. With 105°C Japanese capacitors and Zero RPM fan mode, they’re a great choice for high performance small form factor PC’s where reliability and low noise are essential. AN UNPRECEDENTED 750 WATT SFX PSUIf you are interested in being “green” and saving the planet, you might like to read a short explanation of how our power supplies can save energy using Active PFC (Power Factor Correction), not to be confused with Power Conversion Efficiency which is also very good in most of our PSUs. “Power Factor” is a measure of how efficiently electrical power is consumed. Ideally, Power Factor would be 1 (or 100%) and known as unity. Corsair are keen to point out that lowering noise is one of their key focus points with the SF750. Many small form factor power supplies are equipped with a tiny 80mm fan, which are typically known to generate a lot of noise. By moving to a 90mm fan, they are able to spin the fan slower while producing good levels of airflow – all while reducing noise emissions. They also state that due to careful component selection that coil whine will not be a problem. I will test this out later. Next we want to try Cross Loading. This basically means loads which are not balanced. If a PC for instance needs 500W on the +12V outputs but something like 30W via the combined 3.3V and +5V outputs then the voltage regulation can fluctuate badly. Cross Load Testing 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.
