I really wanted to love this PSU, and in the right case, I think it’s awesome, but I ended up returning it because it didn’t fit my new case layout. What I liked: • Genuinely innovative design. The EDGE’s signature L-shape relocates the modular connectors to make cable routing cleaner and easier specifically in dual-chamber cases (like the O11-style layouts) where the PSU is mounted vertically. • High efficiency + modern standards. It’s 80 Plus Platinum and ATX 3.1 / PCIe 5.1 ready with the newer 12V-2x6 support. Cybenetics testing backs up strong overall performance (Platinum efficiency, solid regulation/ripple, and good hold-up time). • Nice “premium build” extras. You get fully modular sleeved cables with cable combs, and there’s even a built-in internal USB hub (4 internal USB 2.0 headers) which can be super handy for Lian Li controllers/RGB/fan hubs. • Long warranty. 10-year coverage is reassuring. What to watch out for (why I returned it): • Case compatibility is the whole make-or-break. This PSU is optimized for dual-chamber vertical PSU mounting. In more traditional layouts, the “corner/ledge” can be awkward, and clearance can become an issue even if the wattage/specs are perfect. • Check dimensions + cable reach before buying. The unit is about 182mm deep (plus the L-shape geometry to account for), and Lian Li/retail listings also warn that in some non-dual-chamber builds, cable lengths/case size can become a problem. • Noise can be load-dependent. Some testing notes the fan becomes clearly noticeable around mid/high load due to the compact design and 120mm fan setup, even though overall averages test reasonably. If you have a dual-chamber case where the EDGE layout is meant to shine, this PSU offers great efficiency, modern ATX 3.1 support, and some genuinely useful quality-of-life features. But if your case is more conventional (or tight on PSU clearance), fitment can be a deal-breaker, it was for me.

Perfect, quality psu for my build, the angled connectors make life easier when building in a dual chamber build, but additionally the 1300 watts ensures anyone has headroom, whether it’s a 4090 or a 5090 with the latest amd or intel chips. It’s quiet, and additionally with the added USB headers, 5 of them I might add, you can add way more internal USB devices if needed. The built in new power standard connector for updated 4090 and 5090 gpus also is very nice, I unfortunately only have the base 4090 with the old header so I can’t take advantage of the more secure benefits, but the alternate colored header is nice as it’s supposed to be a visual indicator of secure fitting between the cable and the headers. Overall I’d recommend this pay to anyone needing the biggest, most stable, and generally easy to build psu possible, plus cable combs and modular design make it super easy to build with.

Love this PSU, matches the white O11 XL I have flawless, and the L shaped design really helps with cable management. Furthermore, the cables are all modular and are very high quality w/white sleeving & white cable combs. The built-in USB hub is really nice too, though I need to experiment with it more. the 12pin connector works great on my 5090FE, and i've ran it overclocked with no fire/melting issues as verified by a FLIR camera, also the bottom half is blue so it's very clear & obvious when it's not plugged in all the way. Noise level is inaudible, and efficiency seems par for the course as well. I spent about $230 on this PSU, and for how forward thinking this design is - i'd say this is a good value for reference, here's a list of other PSUs I have: EVGA 1600W T2 Corsair HX1200i Corsair AX1200i Seasonic Prime platnium 1300W Seasonic prime 850W and some generic 550w non-modular PSU

Amazing set up , took forever to get here because usps terrible customer service. Came working which is a plus , all the parts tell you which end goes in the psu which is good for a beginner, price vs performance is spot on. Cable length was a bit shorter than expected, especially if you have a dual chamber pc , it works, i just wish it had a few more inches . It's all white except for the powercord . It also includes extra USB hubs so if you have a mother board with one, they got you covered with 4 , French kiss for your pc build lol. It works with all components so theres no worry, it even has a extra cpu cord

I upgraded from an EVGA Supernova 1000 P5 because I wanted a PSU with a native 12VHPWR connector (ATX 3.0/3.1). This new PSU is effortlessly powering an RTX 5090 and a Ryzen 7 9800X3D. The 12VHPWR cable feels very high quality, and I feel much more comfortable using it instead of the goofy 3x8-pin adapter MSI tossed in with my GPU. The "edge" orientation of the power connectors on the PSU itself it great for my O11 Vision case, I have been able to quickly add and remove cables the couple of times that I've needed to do so. I've had zero issues with power using this PSU. Of note - use the cables that came with the PSU. I tried to be lazy when I installed this PSU by leaving the CPU power cables from my old EVGA PSU in place, but it just wouldn't work, even though the cables were identical. I swapped those out for the Lian Li cables and it fired right up. No shortcuts allowed, apparently. My only complaint is that the powered USB hub build into the PSU is only USB 2.0, and only has internal connections. It's very limiting to only have the old school USB 2.0 headers, but I did use it to add my Tryx Panorama AIO, figuring that a powered header from the PSU would be more stable than connecting directly to the motherboard for any odd power spikes that the AIO might have when cycling through my GIFs. I really would have preferred if this had a USB 3.0 header connection or a Type-C header connection to the motherboard instead, with breakouts on the PSU itself for 2.0, 3.0, and Type-C 3.x/USB4 with PD support, maybe with 2 or 4 internal headers and 1 or 2 external Type-C ports at the rear. Maybe in the near future, such a PSU will be made? If you have gobs of USB 2.0 devices in your PC, this is a great PSU for cable management and ensuring that you don't have power issues with those devices from overdrawing power from the motherboard.

I haven't noticed any noise coming from it, and it has a great assortment of cables with cable combs. Looks really good, and makes it easier to rout everything in my lian li lancool 207 case. (Yes, pc part picker says they aren’t compatible, but I have two PCs with this case and, and both have a lian li edge power supply. It fits fine.) Good build quality, pretty easy to install

Looks great, high quality build. Fan run super quiet, had to check to make sure it was running, I couldn't even hear it. The L connection ports are really helpful even in dual chamber cases, makes cabling your PC so much easier. the cables themselves are high quality braided, very soft and easy to manipulate. comes with cable combs to help keep things tidy. Awesome PSU!

High quality PSU with lots of power and built in USB hub. Runs my power hungry PC with no problems at all. The white looks good in my all-white build. Fan is quiet and it never runs hot. The only issue is with cable management. I am using it in a large, dual-chamber case (NZXT H9 Flow) and because of the orientation, the cables are sticking straight out towards the back of the case, and need to make a sharp bend in order for the rear panel to fit. This is making good cable management tricky. It is probably better suited to a traditional case with the PSU compartment at the bottom. That being said, I would still recommend it.
