CORSAIR SF750 CP-9020186-NA 750W SFX 80 PLUS PLATINUM Certified Full Modular Power Supply

Pros: High Quality Power for a SFX PSU. 750W is more than enough for just about any small form factor PC. Fully Modular Corsair warranty and brand quality. Quiet

Cons: It's not cheap. But that doesn't mean it isn't worth it either.

Overall Review: When small form factor PCs became all the rage and SF and SFX PSUs came along, I didn't think we'd see wattage ratings much higher than 500-600. So it's nice to see that there are good quality options coming on to the market that are fairly priced. So you can run a pretty high end machine and do so quietly with this little gem. I'm pretty excited I was able to review this model. It's going to stay in my machine for awhile.

Pros: When I opened the box I couldn't believe how small this thing is, about half the size and weight of my current ATX PSU, yet still supplying more than adequate power with a Platinum rating. It installed like a charm in my Fractal Define R4 mid tower case after I attached the mounting plate. Note: This was only possible as it was replacing (for testing purposes) a Corsair RM850X, which has long enough (and more importantly, pin-out compatible) cables to reach the motherboard headers and peripherals in that case. The supplied cables are designed for a small form factor case and are short enough to route neatly in such a situation. They are also individually sleeved with no ugly capacitors, giving them a very nice appearance, though the sleeving is quite narrow, somewhat like CableMod aftermarket cables. On testing, it ran silently due to its passive (or Zero RPM) fan mode. My system includes a 4790K, a 980Ti, three hard drives, two SSDs, three fans, and several USB peripherals including a TV tuner. I would probably have to run SLI graphics cards to trigger the fan to turn on, but in a small form factor build this would not be an issue anyway. There was zero coil whine and the unit barely got warm, even after running benchmarks like Unigine Valley, and games such as Shadow of the Tomb Raider and Far Cry 5.

Cons: Not cheap, but considering its 80 Plus Platinum rating and 750 watts in such a small package, this is not unexpected. Minor gripe: I had to supply my own screws (6) to fit the mounting plate to the PSU, but in a SFF case you would probably attach the PSU directly to the chassis. There is no way to turn off passive fan mode, although in my testing it was never necessary.

Overall Review: The SF750 was supplied to me by Newegg for the purposes of this review. I can't think of any reason to deduct any eggs. It has run flawlessly since installation three days ago - if this changes I will revisit this review.

Pros: This high-end SFX power supply checks all the boxes: Modular Quiet (including silent mode) 750W is more than enough Compact Platinum efficiency rating Shorter cables for less clutter in a compact case High quality power delivery with great voltage regulation Overall a great choice for any high-end small form factor build.

Cons: The higher price reflects the feature set and form factor. If you don't need all the power, the compact size, etc - there are cheaper models available.

Overall Review: As this is designed for small form factor PCs the cables are a bit shorter - so be aware. It does come with a SFX-to-ATX bracket though if you want to install it into an ATX case.

Pros: Corsairs SF750 SFX Power Supply is a Small Form Factor power supply with ATX pin compatible in reduced dimensions. This is a nice unit and is Platinum +80 rated. It does not have those horrible flat cables. They are braided, individually sleeved cables. It also incorporates a zero RPM fan mode that does not come on till 40% load. Even under load its whisper quiet. According to the reviews it has excellent voltage regulation along with very good AC ripple suppression at full load. 7 year warranty on this beauty, they used Japanese caps and included a SFX-to-ATX mounting bracket. It has a 2x 400mm CPU power 8 pins and PCI-E cable with two 6+2 ends. The fit and finish is suburb and it just looks good sitting in a SFF case. I had no issue installing it and it work perfectly. I believe it’s manufactured by Great Wall power supplies and they have been know for 9.9 JonnyGuru rated reviews on other models. I measured all the voltage rails with a fluke and all were well within specs even under load.

Cons: Could not find anything I didn’t like about this power supply.

Overall Review: Ideally this is meant for a high end Small Form Factor build with a powerful graphics card. This would power any single GPU card out there right now. I wouldn’t even be concerned about having enough. It can also work in a full size case and power any build with a Single Graphics card.

Pros: Modular Quiet running Plenty of power Looks good Decent size Easy install

Cons: There are none....except maybe a bit pricey.

Overall Review: I would highly recommend these Corsair modular power supplies. I have been using them in my home network computers for the last few years and have had zero issues with them. The modular aspect of these PSU's is fantastic. Use the cords you want, save the rest for something else. They run super quiet. My PC: i7 cpu, 16 Gigs of RAM, 2 GB Gaming card, 2 external drives, 3 internal drives, a printer, scanner, 2 monitors and PC speakers. They are costly, but are the best power supplies I have found yet.

Pros: First impression is that this unit is a high quality piece, light years from those cheap, throw-away power supplies that we’ve all used at one point or another. The power supply itself comes in a black velvet bag and when you take it out it has the feel of an expensive, exquisitely piece of technology. It’s heavy and well built. I keep wanting to say ‘jewel-like’ but that may be going a bit too far. Included in the box is a bag of cables, a nicely made, heavy duty power cord and an adaptor plate so you can use the Sf750 in place of a regular sized power supply. There is also a thick and complete manual in 10 languages and a thin warranty booklet. There is also the usual assortment of tie-wraps, mounting screws, Velcro straps and a case badge. Let’s talk about the modular cables. They’re every bit as nice as the power supply itself. They’re individually sleeved in black paracord. These are well built, premium cables that you would pay a lot for if bought in the aftermarket. Looking at these cables begins to explain the premium price for the SF750 unit. The cables are short by regular ATX power supply standards. The main 24 pin cable is just under a foot in length and the two ATX 12 volt cables are just under 16 inches long. Notice I said there are two of the auxiliary 12V cables. This makes it possible to use this unit on high power builds that require two 8 pin cables. There are two 20 inch PCIe video card cables, two 17 and a half inch SATA cables with 4 connectors and a single 13 inch molex cable with 3 conns. I will admit to being a bit biased. I own one of these units. I have an SF650 in a small form factor build using a Phanteks Evolve Shift case. This is not a high power system, using a non-overclockable i5 and a GTX 1060 video card but I do use it for gaming now and again and I’ve never once heard the fan on the power supply turn on. I’m well happy with the SF600 in this system. The problem with using the SF750 in this system is that it wouldn’t even give it much of a workout so I’m going to test it in my main gaming system with an ASUS Maximus Gene XI motherboard, a core i7-9700K and a GTX 2080 video card. This build is in a micro sized Thermaltake Level 20 VT case so the short cable should work OK. Now I don’t have any sophisticated testing equipment so I won’t be able to create ay graphs or lists. All I can do is give you my impressions of the operation of the SF750. First off it works fine. I’ve had it running in my main gaming system for 4 days and it hasn’t hiccupped. I’ve played Far Cry 5 and Tomb Raider at 4K resolution and ultra detail and the fan in the power supply hasn’t turned on much at all. The unit is virtually silent most of the time and when the fan does run it’s inaudible. The short, individually sleeved wires make for a clean installation although you’ll need those tie wraps to get them into orderly bundles. The connectors fit into the power supply easily and don’t come loose. This is a platinum rated power supply so you should get above excellent efficiency. The end result is the SF750 was cool and quiet and performed perfectly.

Cons: It’s expensive. You could buy a regular 1000 watt modular ATX power supply for the same price. It’s almost overkill for most mini ATX systems and the short cable set limits its use in bigger systems. No RGB to impress your friends.

Overall Review: What Corsair has created with the SF750 is a niche product that is both beautifully crafted and way too expensive. It’s specifically designed for high power small form factor builds. It’s capable of running SLI video cards but few mini ATX motherboards have that capability. It’s a little gem of a power supply but the short cable set limits it use in full sized ATX chassis. I love it and I’m going to build a small Form factor system worthy of its capabilities. But I do recognize that not everybody needs a unit like this. Still, it is a quality piece of technology. Power supplies rarely get any glory in an enthusiast system. You don’t even see most of the time any longer. But I’ll know the SF750 is there and it will give me a warm feeling inside.

Pros: Until you're actually holding your old full ATX sized PSU in one hand and this SF750 in the other, you won't believe the difference, it's impressive. The appearance and quality is as expected from Corsair - excellent. And it's so quiet, even when under load. Being so used to hearing things spin up in my old rigs, when powering this one on I have to do a double take at it to see that the power light came on since this PSU's fan doesn't kick in until there's load.

Cons: I'd like to say price but I can't deduct any points considering they're able to pack 750 watts into a box that is less than half the size of my old 750 watt ATX PSU. It's worth it's weight. I haven't seen or read anywhere else mentioning the heat this thing puts out under load but this is the con and it's a bit concerning. I've experienced a few shut downs although I am unsure if it is due to the OTP or a problem with the power extension cable that was included inside my Node 202 case (the plug is not snug and has a very short contact depth) - when things get hot and expand the plug actually slides off just enough to lose contact with the pins. I'm still testing this but am curious if others also find theirs runs hot too. (*my PSU is pulling fresh air directly from outside the case)

Overall Review: I've just built a new SFF style rig and the PSU is the best part that I show off to everyone. I can't get over how small it is. Adding an additional fan is likely impossible or else it wouldn't fit in cases such as my Node 202 so more venting for passive cooling would be nice. Adding a temperature sensor would also be handy with a means of controlling the fan speed via auto/manual.

Pros: Fans are really quiet when they spin. The cables were really easy to work with. Comes with SFX-ATX Bracket. Really really small.

Cons: No option to disable 'ZERO RPM FAN MODE', I would have prefer to be able to choose a fan mode. It gets really hot and the fan doesn't spin until it meets a certain load. That heat ends up radiating in my case.

Overall Review: It is a great power supply in a very small package. I like that it is silent, even though I wouldn't mind the if the fan was always on. It is still very quiet even under load.
