The sides of the power supply are decorated with angular shapes stamped into the metal casing. The power supply is … Ripple suppression overall is excellent. For example, barely anyone needs above an 850W supply, so why spend the money? Below this, the fan never spun at its maximum speed and, , though in this aspect the EVGA 450 B3 does. Below this, the fan never spun at its maximum speed and spun at its lowest speed most of the time. Because PSUs are so important and should last for the long term, they. Then add a bit extra for security, and in case you plan on updating other components to something more power-hungry later. This product is the first of its kind, and we are expecting more Connect models in the near future. It was just 30dbA at full load at 46°C, compared to the Seasonic SSR0750PX which reached 45dbA. Most users will be more than happy with the stellar Corsair RM750x, a great all-round performer with enough juice for everyone. These worked well, as ripple suppression on all rails was top-notch.

It didn't take us long to install the PSU and its backplane into a Phanteks Evolv X case, which offers ample space, but it doesn't have much clearance behind the motherboard's tray. Thanks to the Connect module, installation is easy, and most important of all, the shorter cables increase airflow inside the chassis leading to lower operating temperatures. Testing can tell you exactly how efficient it is at different loads, compared to competitors. Even at 100% load and over 46°C, the noise was below, . However, testing by third parties has shown it to be even better at. However, noise-wise, it has a LAMBDA-A- noise certification. In fact, KitGuru found this model’s ripple suppression to be in the top, , a rarity on fanless models, 6 SATA, and 5 Molex. And finally, it comes with a nice 5-year warranty. Up to 270W, it’s only 28dbA, which is just above a whisper. 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. The build is excellent. 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. However, testing by third parties has shown it to be even better at 96% at 50% load, and 93.5% at full load. as well, which is a definite plus when spending long hours gaming. Those two parts are connected through a thick cable, which transfers the afore-mentioned rails to the Connect module. This is due to its excellent build. Please refresh the page and try again.

There’s a 135mm fan with a rifle bearing and microcontroller, which reduces noise. It’s got an 80 plus Gold efficiency rating, which is impressive for the price. will be best off with Bitfenix BF450G, if they can get away with the lower wattage. . One of its main competitors at this price point, Seasonic’s SSR-750FX 35, was almost double at 35dbA. The latter provides temperature data to the over-temperature protection circuit. The converters mentioned above are on the Connect module. SeaSonic even included a basic PSU jump-start adapter for users to test their PSUs without having to connect a system.

It’s semi-modular, with 2 PCIe connectors and 2 SATAs. , helped by high-grade 105c Japanese capacitors throughout. The +12V rail can handle a stellar 50A, and the 5VSB rail an average 2.5A. Besides electrolytic caps, which are provided by Chemi-Con, there is also a high number of polymer caps. For the inrush and surge protection, Seasonic used an NTC thermistor along with a bypass relay and an MOV. Check what connectors the PSU has, and make sure you’ve got the cables to match, with the right power supply. you can buy. Seasonic SS-300TFX can really deliver its labeled power at high temperatures. The PCIe and EPS connectors are powered by dedicated rails. , which makes cable management a bit difficult, but you can’t expect too much at this price point.

There are 3 heatsinks and the entire thing is vented to allow maximum airflow. This means a 94+% efficiency level at 50% load, and 90% at 100% load. Again though, there’s only 10cm distance between these, which is less than ideal. Seasonic thought that it would be better, for cable management purposes, if it broke down the PSU into two parts: one is the main power supply generating +12V, -12V and 5VSB and the second part is a cable-hub backplane, which is mounted on the chassis through strong magnets and it is completely hidden behind the mainboard's tray.

With the provided magnets, you can quickly hook up the backplane in any place that allows for all cables to reach the corresponding sockets. Well, modern systems don't heavily utilize those two rails, so the thermal loads remain low. We will update if a solution is found. On this side of the PCB, you will also find the supervisor IC. 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. who need a bit more capacity for that power-hungry GPU should go for its big bro, the Corsair RM850x. Again there’s 2 EPS connectors, 6 PCIe ones, and lots of peripheral connectors, including 8 Molex connectors.
