Pros: Seasonics Syncro design Power supply has a modular cabling design that is completely new to the industry. This PSU is meant to be installed in the Seasonic Syncro upside down ATX Case with an aluminum body, tempered glass and it opens on the left not the right. So, if you need a case to sit on your desk on your left side then this is your case and power supply. The build quality is good, plastic modular piece and its laid out well enough. The finish is a strong powder coating or maybe anodized, the fit is good and everything goes together like its designed. Everything seemed to work as designed. It has a switch on the PSU for Eco-Friendly mode. I ran a voltage drop test with a fluke and all voltages were within specs.

Cons: The power supply is proprietary and will it is questionable whether it will work in other cases. There are some videos out that show using stickers and magnets to put the connect module in standard ATX cases.

Overall Review: I really like this case and power supply set up. It has a few small announces but the quality and build are superb. Im not a fan of preparatory hardware but I get the objective and appreciate the cable management. I dont think we will be seeing any Mini or ITX cases in this line up. Its kind of a one size deal. Because of the inverted design it may be optimal for a custom water-cooling loop leaving more room for radiators in the top and front. I just watched a video on how to install the modular in a standard ATX case using magnets over the standard cable routing holes. So I guess the Power supply can be used in some cases besides the Syncro

Pros: 1. Reverse-ATX Design: The motherboard mounts in the case upside down (CPU at the bottom, PCIe slots at the top). The motherboard mounts on the left (not the right) side of the case. The Tempered Glass Side Panel is on the right (not the left) side of the case. Seasonic offers custom PSUs for the case with a unique Power Distribution / Cable Management Cover (a.k.a. CONNECT Module Cable Management). 2. Very sturdy, thick metal, no exposed sharp edges. The Tempered Glass Side Panel has a steel frame, and full length Aluminum Handle that matches the Aluminum Front Panel on the front of the case. The Power and Reset buttons are solid. The Power LED is a White Line on the side of the Power button (towards the front of the case). See Cons #4. Dust covers for the top audio jacks and USB ports. See Cons #5. 3. Four included 120 mm fans. Three in the front (intake), and one in the rear (exhaust) of the case. See Cons #3. 4. Lots of Magnets, holding the Tempered Glass Side Panel closed, also holding the Dust Filters, Cable Management Cover, etc. 5. Well packaged in a sturdy oversized box. The case is suspended on both ends by thick foam. The case itself comes in a black fabric bag. Both sides of my box were damaged in shipping (by large punctures). Fortunately the case itself was not damaged. 6. Accessories come in their own cardboard box and includes: the users manual, a plastic "toolbox" of screws, a pair of fabric gloves, a soft cloth, and Velcro cable ties. 7. 10 YEAR WORRY-FREE WARRANTY on the PSU, 2 YEAR WORRY-FREE WARRANTY on the case.

Cons: 1. Expensive, unless you can find a Combo deal (i.e. Case plus PSU). Proprietary PSU. 2. Very Heavy (over 33 pounds with power supply). The Tempered Glass Side Panel alone weighs about five pounds. The PSU is over five pounds (depending on the cables used). The glass door is easy to remove, just swing it open by the aluminum "handle", and slide it upward off the two hinges. However, the glass door needs to be open almost 90 degrees to remove and replace (i.e. you need a lot of room). 3. The three front 120 mm fans come pre-plugged into a 1-3 PWM Fan Splitter Cable. The cable on the single rear 120 mm fan is very short. All four included case fans have "odd" four pin connectors. The polarity tabs are longer than normal. I was unable to connect the four included case fans directly to the PSU CONNECT Module Cable Management fan ports. I had no issue connecting the 1-3 PWM Fan Splitter Cable to the PSU CONNECT Module Cable Management fan ports. I had no issue connecting other three and four pin fans I own to the PSU CONNECT Module Cable Management fan ports. I had no issue connecting the four included case fans directly to my motherboard fan ports. 4. No HDD LED (which I miss). Stupid in my opinion. If you don't want an HDD LED, just don't plug its two wires into the motherboard. 5. The Audio and USB ports are on the top of the case, just waiting to be filled with dust (once the covers are removed). The USB-C cable is too close to the CONNECT Module Cable Management and does not lay flat as you close the Metal Side Panel. 6. The four thumb screws holding the Metal Side Panel and Power Supply Bracket to the case seem kind of cheap, and easy to strip the threads. I believe they are actually designed to remain attached to the Metal Side Panel and Power Supply Bracket when they is removed from the case.

Overall Review: 1. This first thing you need to do is remove the metal retaining bracket that holds the glass door closed. There a two tiny Philips screws, on the bottom of the case, holding the metal retaining bracket in place. I put the two screws back in their holes to prevent from losing them. I put the metal bracket in the accessories box to keep from losing it. 2. The PSU is smaller than a normal ATX PSU. It only generates 12 Volts. The CONNECT Module Cable Management converts 12 Volts into 3.3 and 5 Volts. The PSU attaches to a bracket (with four standard PSU screws). The bracket then connects to the case with two thumb screws. The CONNECT Module Cable Management attaches to the (outside) left side of the case with five small screws. 3. The PSU will not Power On unless all three cable bundle connectors are plugged into the CONNECT Module Cable Management. Its easy to dislodge the smallest connector (the one with no retaining clip); the PSU will NOT even Power On unless it is fully inserted. 4. No place to mount an Optical (CD/DVD) drive, but they are pretty much obsolete now. Conclusion: If you like the look and size, and don't mind the weight or expense, you will probably love it. It's a matter of taste. It wasn't really my thing, but it grows on you.

Pros: This power supply provides shorter cables, and I love that its Modular so you can add the cables you need, and don't have all these extra cables in your case making it messy. Almost silent compared to other power supplies. I recommend only using this with the Seasonic Syncro Q704 case as its shape, and cables are all perfect for this case.

Cons: Can only use it with Seasonic Syncro Q704 case. Not really a con, but for some people that don't want to spend that kind of money on the case I could see this.

Overall Review: I would recommend this power supply to anybody going to Lan parties or the person who has OCD on how their computer case looks.

Pros: When paired with the SYNCRO Q704 case, cable management just got a lot easier! Sturdy, well built PSU from a reliable brand All the cables I needed were included, no fishing in my bin for something

Cons: This is intended to be paired with the matching case (SYNCRO Q704), so I do not feel calling it proprietary is a con. It would be if this was all that Seasonic made, but it is not.

Overall Review: As another had mentioned, I have never seen a PSU come with a tester. While it is a basic one, it was still a surprise when opening the box. As I mentioned above, when paired with the SYNCRO Q704, cable management is made easy with this PSU. That case has a spot dedicated to the Connect Module. I have never been mistaken as a cable management master in my past builds, but I did try my best. It got a lot easier with this combo though. No case door bulging on the back side or zip ties to pull a bundle out of the path of a fan. The 650W was enough to handle my build: 10900KF, RTX 3070, Z490 mobo, 32GB DDR-3200, 2 NVME's and a SSD. It has been awhile since I have used Seasonic and this Eggxpert opportunity was definitely brought me back to the brand again.

Pros: This is a nice power supply. 1. 850 Watts - powerful 2. Direct fit for Syncro Case Q704 - this installation is nearly seamless 3. Lots of special designed cables 4. The tunnel box has some power supply function, so very little wiring to the power supply itself. 5. Not overly long 6. Relatively quiet

Cons: You can only use this with the Syncro Case number Q704. Do not buy this power supply, unless you have the matching case.

Overall Review: This items should be needs to be used in the Syncro case. You could probably put together another case to work with it. However, you will need the long bar, so modding of the case is a must. This gives the average user no hope for it unless you use the Syncro Case. I like both, a lot. The performance of the power supply is goo. It has ample for panel for most users. The case that goes with is really a luxury item. However, the cable management in this case with the combined power supply is unique, and gives you options to have a really nice build.

Pros: This power supply is designed to work with the Seasonic Syncro Q704 case. The power supply could be used with a standard case I suppose but Im thinking some modifications would be required. Seasonic does sell 1 power supply that is the same design as the Syncro Connect but has a different module design that might work in a standard case. The 750 watt is one of three Seasonic power supplies that, as far as I can tell, are physically identical and all designed to work with the same Seasonic case. They consist of a standard box power supply with a single 12V cable attached and a special module that the cable connects to and then fits on the back of the case in place of the cable management cover. A series of modular cables fit into the module and from there into the motherboard. The result is a drastic reduction of cable mess. The basic power supply module mounts the same as a regular power supply. I mounted it down in the case because the dust filter was on the bottom so the fancy chrome fan grill wasnt visible. Then you remove the cable management channel supplied with the case and the module screws perfectly in place. Then you mount the cables the same way you would mount a regular modular power supply. There are (2) 8 pin auxiliary motherboard power cables and (4) single PCI-E video cables. The power module has lots of (4) pin PWM fan mounts as well as RGB conns. I cant find out anything about how they are supposed to work. The thin instruction manual doesnt mention them. But there are included cables that hook up to the module and then to conns on the motherboard so Im guessing these conns might be controlled by motherboard fan and RGB headers. Very clever, Seasonic. It all works well and is ingenious. While you are assembling this combo you cant help but wonder why somebody didnt come up with this before.

Cons: The why is that the power supply and case might be elegant but they serve a limited function. With modular power supplies, I dont hear a lot of complaining about cable clutter. And no doubt a standard power supply has to cheaper to manufacture then this one. Right now you are tying yourself into a single infrastructure because I cant see buying this power supply paired with a standard case. If there are more cases produced that utilize this type of power supply then it would be an easier sell.

Overall Review: This power supply is an engineering tour de force. Its well made and works beautifully. I commend Seasonic with coming up with the idea. But I fear that unless there are more cases in the same family, it will remain a niche product. Even so it is a beautiful piece of work.

Pros: This PSU was combined with a Seasonic SYNCRO Q704 Case. The Seasonic SYNCRO DGC-750 PSU is a remarkable twist on the same old modular designs. Cable management is simple and elegant. It comes with more than enough cables and ties. Fan control is easy. I am glad I went with PSU, if I had not I don't feel it would have come out so well. All cables are hidden and it looks great without a lot of headaches.

Cons: Not a con but I was a little confused with all of the cables

Overall Review: I made a remarkable build and I look forward to getting a new MB with features that will enable me to use the PSU and the case to it fullest
