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. 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. 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. 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.
Oct 16th 2023 Thermaltake Unveils Its First Ever Bumblebee-Colored Product in The Tower 200 Mini Chassis Series (19)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). 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.
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. 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. At 788 watts, the efficiency level measures 91.6%. Not a practical situation to be running 24/7, but worth noting. If 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. 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.Ferrum MasterLegally their Toughpower SFX Series is mentioned everywhere, it doesn't mean that those have compliance with the SFX sizing.
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. The Revolt SFX Power Supply will be available in 650 W/750 W 80 Plus Gold and 750 W 80 Plus Platinum. 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". 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.It is not usually practical to reach unity, i.e. Power Factor 1, and it seems that most electricity supply companies accept consumers having a Power Factor as low as 0.94 (94%) without imposing a surcharge. Unfortunately most of the cheap (and not so cheerful) PSUs tend to have a Passive PF as low as 0.75 or 75% which in a large office can lead to a PF surcharge.
