The SF750 Platinum delivers power at up to 92% efficiency, lowering energy consumption, noise, temperatures, and your power bill. JAPANESE 105°C CAPACITORS 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) 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. 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. 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.

Ferrum MasterLegally their Toughpower SFX Series is mentioned everywhere, it doesn't mean that those have compliance with the SFX sizing. 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. Compatible with both the latest Intel SFX 12V 3.42 and ATX 12V 3.0 standard and designed with native PCIe 12+4pin modular interface.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. 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".

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) 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. 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. Zero RPM Fan Mode: The fan stays off until it’s needed, for silent operation at low and medium loads. Investing in one of the best 750 W PSUs will ensure that your computer runs smoothly and efficiently without issue. These power supplies offer enough juice to power upper-midrange components while still being affordable enough for lower-powered rigs that want to upgrade headroom. So it’s a great sweet spot for many users.Load regulation proves to be very good, holding within 2% of the recommended guidelines. Corsair SF750 SFX Toughpower SFX series is fully compatible with Intel ATX 3.0 Specifications which supports up to 200% power excursion, reaches 70% low load efficiency and complies with required power supply timing standards. 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. The Revolt SFX series power supplies are available with two gold-rated models of 650 Watts and 750 Watts and a platinum series PSU at 750 Watts. These small form factor PSUs feature a 92 mm fan that remains at 0 RPM below a 30% load to reduce noise while idle. Manufactured by Seasonic, the Revolt SFX power supplies ensure quality and dependability. Below is Phanteks press release. PHANTEKS LAUNCHES EVOLV SHIFT XT ALONG WITH REVOLT SFX POWER SUPPLIES 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 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.DC-DC Converters: 4x Infineon PSMN2R0-30YLE (30V, 100A @ 100°C, 2.8mOhm @ 100°C) PWM Controller: APW7159C

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. 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.

This helps to reduce the losses in the electrical supply to that equipment. Power Factor Correction capacitors are normally used to reduce induction in an electrical load, which minimises wasted energy and hence improves the efficiency of a company and reduces electricity costs.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.
