CORSAIR SF Series, SF750, 750 Watt, SFX, 80+ Platinum Certified, Fully Modular Power Supply

Product Information

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. Load regulation proves to be very good, holding within 2% of the recommended guidelines. Corsair SF750 SFX 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.

high quality Japanese 105°C/221°F capacitors provides great durability as well as offering the highest stability, while remaining reliable.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 At 788 watts, the efficiency level measures 91.6%. Not a practical situation to be running 24/7, but worth noting. 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.

isn't SFX, it's SFX-L. None of the other SFX and SFX-L makers stoop to this level of bullshit marketing, TT. No other company does this "well technically it's all officially SFX" because they understand that the extra 25mm makes or breaks SFF builds.Yep, this is pretty terrible marketing wise. Looks like a good PSU (though of course that can't be judged from specs alone), but being clear about its form factor is a pretty basic requirement. Then again, this is Thermaltake. Their slogan might as well be "There is always something wrong with our products". Zero RPM Fan Mode: The fan stays off until it’s needed, for silent operation at low and medium loads. 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.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. Not cheap actually... just high margin, larger sizes does make life easier on BOM costs.Honestly, SFX-L is perfectly reasonable even at that cost for 1000W. It is possible to make a 1000W SFX unit, but it would take pretty much the best possible components today, and would still struggle with cooling and having sufficient bulk capacitance to support ATX 3.0 power excursion specs. Sep 7th 2023 Thermaltake Reveals Matcha Green Lineup: Ceres 300 TG ARGB Mid Tower Chassis & ARGENT E700 Real Leather Gaming Chair (8) Today to test the power supply we have taken it into our acoustics room environment and have set our Digital Sound Level Noise Decibel Meter Style 2 one meter away from the unit. We have no other fans running so we can effectively measure just the noise from the unit itself. 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.

The 90mm fan is hidden behind a metal grill on the top of the unit. We will get a closer look at this shortly when we open the power supply.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. 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. On the software side, the test setup includes Windows 10 Pro with Furmark and Prime95 both running at the same time to put the maximum load on both the processor and the graphics card. 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.

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. 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.

An Unprecedented 750 Watt SFX PSU: Harness 750 continuous watts in SFX form, perfect for the most power-dense small-form-factor PCs. PLUS Platinum Certification: Ensures ultra-high efficiency operation for less excess heat and lower operating costs. 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.
