assuming it is, can I swap the modular cables only at the PSU side or will the cables be different gauge wire? I currently have a custom water cooled rig with a Corsair SF600. I have gone with an SFX as space is at a bit of a premium with all the tubing and cable management. 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 SF750 will let you draw more than 850 watts without shutting down but I don’t think that’s such a hot idea. This is the first desktop PSU with fan failure protection I have come across. In other words, if the fan has a problem or the PSU doesn't detect it, which would happen if it isn't connected, the SPX-750 won't start. 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. Would i get another? I don't know, i know they're Seasonic OEM's... a majority of these SFX-L's are hence all sharing the same problems. I will do my research if i upgrade again and see which ones are OEM's from which manufacturer and decide from there on like i did with this one.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. So for 1973 Laverda’s 750 twin got the boost it needed, in the shape of the SF1. By this time sound level regulations were intruding so Laverda was faced with the conflicting difficulties of increasing gas flow and decreasing exhaust noise. Laverda achieved both ends with large diameter exhaust pipes (1.6-inch) interconnected by a transverse collector box, new style Dell’ Orto 36mm pumper carbs and a matching new camshaft. These mods lifted power to a claimed 66bhp at 7300rpm, and top speed rose accordingly to around 117mph. Last time, Dave Minton introduced us to Laverda’s 750 parallel twin. In the mid-1970s it got faster, lighter and more reliable… 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. Due to public requests we have changed our temperature settings recently – previously we rated with ambient temperatures at 25C, we have increased ambient temperatures by 10c (to 35c) in our environment to greater reflect warmer internal chassis conditions.

Depends entirely on the whole combination. Can get power hungry CPUs and power hungry 3090's / 3080Ti's that go well above FE at times when OC'd. I've put it though a few hours of testing and the highest complete system power I have managed to achieve is 620w. Thank you! Do you think then that even the 600 would be enough or should I definitely make the jump to 750? Most of my gaming is 1440p and I limit the frame rate to 144. I don't see the point in going over that when my monitor is 144Hz. I have many power pig cards and I found the single cable and pigtail combination works with cards want three PCIe cable connections.Sometimes I will game on the TV which is 4K 120Hz, but that's only for the odd controller oriented game My main concern is that 750W may be a bit close for such a high power system, especially with the addition of 7 QL120s, EK DDC pump, etc... Correctly testing power supplies is a complex procedure and KitGuru have configured a test bench which can deliver up to a 2,000 watt DC load. I am about to buy a new psu right now and it will be my first build after 15 years. I want to have a build as silent as possible. So i wonder which psu from Corsair should i choose?

Electrolytics: 1x Nippon Chemi-Con (4 - 10,000 h lifetime @ 105 °C, KY series), 2x Rubycon (3 - 6,000 h lifetime @ 105°C, YXG series) 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. The 90mm fan is not active when the power supply is running at lower power demands. We didn't hear any coil whine either, which is excellent. At higher loads, the fan does spin up a little more, becoming more audible when the load hits around 600 watts. At full load the fan is clearly audible, but it is only 90mm and we would expect this.Desktop: Intel Core i9-9900K | ASUS Strix Z390-F | G.Skill Trident Z Neo 2x16GB @ 3200MHz CL14 | EVGA GeForce RTX 2070 SUPER XC Ultra | Corsair RM650x | Fractal Design Define R6

Individually Sleeved, Fully Modular Cables: Flexible paracord sleeved cables make routing and cable management incredibly easy. I noticed the SF750 has 2x GPU cables and 2X CPU 8 pin cables which kinda make no sense for an SFX PSU. I don't understand why they would include 2 x 8pin CPU cables. I don't think i've seen an ITX board require more than 1 x 8 pin connector. Is it safe to connect the extra CPU 8 pin to the 3rd 8 pin connector on the 3080/3090? 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. Today we take a look at one of the newest power supplies from market leader Corsair – their new SF750 SFX Platinum. Previously the SF Platinum series shipped in only 450W and 650W capacities, so this new high model will appeal to the hard core enthusiast user looking for a high wattage small form factor supply. This supply also features a larger 92mm fan, rather than 80mm and it has a ‘Zero RPM Fan mode' to reduce noise output under lower load situations. I would power limit the 4090 to about 70–80% as a good start. Cyberpunk seems a good one to load up especially with heavy RT enabled.To my fellow SF750 owners, if anyone is getting an AIB 3x8 pin RTX 3080 / 3090, are you going to run the 2 x 8 pins from one rail and use the 2nd rail for the last 8 pin? Is this safe? Nvidia recommends using separate cable connections for each 8 pin connector, i was wondering if this was the same for Board partner versions. KitGuru says: If you are building a high end gaming system inside the SFX platform then this should be right at the top of your list.
