Previous AMD announces the Radeon Pro W5500 and the W5500M workstation GPUs. around 100w), this model is silent. Finally, you’re going to want to make sure the PSU is actually compatible with your system, or you’re going to have major buyer’s remorse once you’ve unboxed it. It would work in some specific scenarios but it's almost like removing the benefits of the modular psu and making a nicer non-modular psu. And the most important question is, can you get more for your money elsewhere? The minor rails are too strong, with 150W maximum together, whilst the 5VSB rail has a maximum output of 3A. Now, what about the cooling of the DC-DC converters. The cables have decent length, though, and the ATX, EPS and PCIe cables include inline caps for improved ripple suppression. Well, modern systems don't heavily utilize those two rails, so the thermal loads remain low. The best streaming requires total silence, and that’s what you’ll get with this, . It gets the checkered flag without a single glitch. Editor's Note (4/26): Seasonic informed us that will look into the noise and EMI cons that we highlighted in the review. With power supplies, there’s a whole host of things you can measure, such as ripple measurements to measure ripple suppression, cross-load tests and infrared to measure temperature. . Seasonic is well known as a stellar power supply manufacturer with all power supplies in their lineup performing exceptionally. EVGA’s 850 G3 and Seasonic’s SSR-850FX are the main competition, and they don’t achieve the same noise rating (LAMBDA-S++). The problem is the 130mm HDB fan gets a bit overly aggressive, rotating faster than most at lower temperatures. Check the physical dimensions of the PSU to make sure it will. will be best off with Bitfenix BF450G, if they can get away with the lower wattage. The soldering quality is good enough. The above features give a good idea of quality, but to really compare one PSU against another, you’ve got to perform, Sure, there’s an efficiency rating of 80 Plus Gold, but that. . Time will tell whether the lack of active cooling in the Connect will be an issue for some users that might load more than the typical minor rails. The real beauty of this PSU is its volume; It’s average noise level (between 30-32°C) is just. Even within this, it tested over 89% efficiency, better than most competitors. The minor rails can deliver 22A combined. but i like the idea and do hope we get more and more of these. At 500W it’s around 33dbA. July 21, 2010. Seasonic | Power Supply for Computer JavaScript seems to be disabled in your browser. This is due to the Silencio FP 120mm fan, which has an LDB (Loop Dynamic Bearing) design with low vibrations and an ultra-low current. Seasonic Platinum 660W Power Supply. This cable could be modular as well, but Seasonic decided to make it modular for lower voltage drops since, through this cable, the PSU's entire output has to pass through, under full load scenarios. The main fixed cable, which connects the PSU with the backplane, looks short at 220mm, but there is no need for a longer cable, even with large chassis. Seasonic FOCUS Plus Platinum 550W PSU Review. an’t go wrong with the Cooler Master MasterWatt 650. The last thing you want is an inefficient machine due to poor power, especially after spending all that cash on the best components. The problem is that you add a modular connection, but if you use a short enough main cable to link the PSU to the Connect module with thick wires, this is not a significant issue. The main FETs are installed into a full-bridge topology, and as usual, an LLC resonant converter helps in lower the switching losses. The power might not be enough for some, but if you can swing 450w, this is definitely the best all-round choice. Nonetheless, this specific Prime model uses a design that is identical to Seasonic's Focus line, with the significant difference being the use of a larger, 135mm, fan. Short distance between peripheral connectors, It’s fully modular, meaning no messy cables. Seasonic SSR-750PX . It’s got the top Cybenetics noise rating of LAMBDA-A++, which promises silence. will definitely be enough for most people. The ATX cable has capacitors to help reduce ripple on the PSU’s outputs. On top of that, Seasonic uses a heat sink that's large enough to do a pretty good job. 3 +12V rails deliver 450w combined, and the 5VSB rail can deliver up to 2.5A. They wouldn’t give out 10-year warranties if they weren’t sure of a quality, long-lasting build. Most users will be more than happy with the stellar Corsair RM750x, a. . Up to 270W, it’s only 28dbA, which is just above a whisper. , which definitely can’t match the premium 750w models, but you get what you pay for. The warranty is 5 years too, which is very decent. The connectors include the popular 8 four-pin Molex connectors, though the distance between them is 10cm, which is a little tight. Moreover, if there were any reliability issues, Seasonic wouldn't provide a ten-year warranty to this product. By Aris Mpitziopoulos 25 April 2020 This isn’t the best, but it certainly doesn’t mean it’s ‘noisy’. . It’s 20mm shorter than its predecessor, meaning it’s more likely to fit into your build. It has an average noise of 27.31dbA. A long warranty also shows you the confidence the manufacturer has in its own product. For comparison, this is louder than Corsair’s similar models. Corsair AX1000 – if you need top-end power for things like 3D rendering, this is the best 1000W option. There’s less than 15cm between the peripheral connectors, which isn’t ideal, but it’s limited by its overall size. But at least Seasonic puts its money where its mouth is with a, If you want to game on a budget, look no further than this solid Cooler Master series. Rating: 9.0. Finally, those on a strict budget will be best off with Bitfenix BF450G, if they can get away with the lower wattage. Specifications and Part Analysis. . There are 2 PCIe connectors and 2 4-pin Molex connectors. The above features give a good idea of quality, but to really compare one PSU against another, you’ve got to perform real-life testing. Fortunately, we’ve ranked the best power supplies: overall, as well as for gaming, video editing and streaming, and budget options. Like the 750 model, there’s a 135mm rifle bearing fan. Ripple suppression is solid, helped by high-grade 105c Japanese capacitors throughout. you can buy. , or you’re going to have major buyer’s remorse once you’ve unboxed it. It’s a high-quality fully-modular build with an 80 Plus Gold rating, and as a bonus, it is very quiet. The +12V rail delivers all of the PSU’s capacity, the minor rails are perfectly capable, and the 5VSB rail can deliver a large 3A. Then add a bit extra for security, and in case you plan on updating other components to something more power-hungry later. If you don't take into account the single cable that connects the PSU to the Connect module, you can state that this is a fully modular PSU with ultra-short cables, thanks to the Connect technology, which takes away the need for long cables. It’s well-protected from voltage spikes and large inrush currents as well. Plus, higher wattage PSUs will mean a higher electricity bill and tend to generate more heat and noise. Compared to its predecessor, it’s 2cm shallower, has a second EPS connector, and more peripheral connectors, all of which is much more practical. The main PCB lacks a modular panel and the DC-DC converters that generate the minor rails, so there is lots of space among its components, which allows for increased airflow. It’s very quiet, with a LAMBDA-A++ certification, which again is surprising at this budget, and shocking since it doesn’t even have a semi-passive mode and a small 120mm fan. Sure, it’s not as exciting as graphic card shopping, but a PSU is the heart of your PC. Thanks for the thorough and comprehensive review, Aris!
