Seasonic (Finally) Enters The Titanium Efficiency Club, Outs Several New PSUs


From now on, Seasonic's flagship line will be the Prime, which includes three families of products with Titanium, Platinum and Gold efficiency certifications. Seasonic was rather late to the Titanium efficiency club, but it's better to be late with a good product in hand. Without a doubt, Super Flower is pushing hard in the high-end category, and this means that Seasonic, along with the rest of the OEMs, has to carefully plan its next steps. However, we believe that competition is good for consumers because it pushes R&D teams to create better and less expensive products.
 


The Titanium Prime line consists of four members with 850W, 750W, 650W and 600W capacities. The smallest of them uses a passive design, meaning that it doesn't have a cooling fan, offering the lowest possible noise output. To the best of our knowledge, this the only Titanium fanless PSU available on the market. With 600W capacity, the fanless Prime unit will enable a super-silent build that also performs for gaming. The newest GPUs promise low energy consumption, meaning that you don't need a monstrous PSU to power two high-end graphics cards and a potent CPU--at stock speeds, at least.

The Platinum Prime line includes three members with 1.2 kW, 1 kW and 850W max power, and the Gold Primes feature exactly the same capacities.

As you can see, Seasonic decided to offer up to 850W Titanium units; that decision might seem strange considering that Super Flower has a 1.6 kW Titanium unit in its portfolio.


Besides the high-end Prime models, Seasonic also revealed the Focus series, which is more price-focused according to the company. The Focus line includes three sub-lines that consist of fully modular, semi-modular and non-modular members.

Seasonic also introcued a Platinum Focus line, consisting of two sub-families with fully modular and semi-modular members. Their technical specifications and most important features are listed below.

The Focus lines include 20 members with Gold and Platinum efficiency certifications and all possible cable design configurations. This is hands down Seasonic's largest family of products.




Seasonic's new Air Touch unit features Platinum efficiency, a fully modular cabling design and 850W max power along with appealing external looks. This PSU also uses a 135mm Fluid Dynamic Bearing fan featuring a hybrid digital RGB fan control with a five-mode smart control interface. According to its manufacturer, the fan's speed and the RGB LED lights can be easily personalized through software. Only one touch of the user's finger is enough to set the desired fan speed and the ambient lighting color, which provides an indication about the fan's operational mode (red: turbo; yellow: high; green: mid; blue: low; white: silent). Finally, the Air Touch PSU is backed-up by a seven-year warranty.

    A powerful line up nonetheless!

    "As you can see, Seasonic decided to offer up to 850W Titanium units; that decision might seem strange considering that Super Flower has a 1.6 kW Titanium unit in its portfolio."

    Only if you've bought into the ridiculous idea that only (increasingly rare) tri and quad GPU setups need or want high efficiency PSUs. Or, of course, the even dumber idea of buying ridiculously overpowered PSUs. That fanless 600W unit could probably run dual GTX 1080s in SLI with a <100W CPU, although it'd be getting close to max output when GPU power spikes (Tom's' own testing showed stock clocked 1080s averaging 173W under gaming loads, but spiking to ~300W). After all, what's the point of Titanium with its improved 10% load efficiency if that 10% is way beyond the idle power of your PC? Building a modern PC exceeding 1000W at non-power virus loads is really, really difficult.

    PC components are making huge strides in efficiency. It's time the PSU industry got it's foot out of its a** and keep up. Lian-li's new SFX-L PSUs seem like a good evolution - smaller PSUs with decent efficiency and low noise are a must for modern form factors. Proliferation of low output, high efficiency PSUs are a huge step in the right direction too.


    For me, the star of this line-up is the 450W Focus Platinum unit. From what I've seen, it's the first platinum efficiency unit offered at that low power - perfect for a high-end mainstream setup with a single GTX 1070 or 1080 (and probably Vega too), not to mention mainstream setups with R9 480s or GTX 1060s.

    I really hoped to see a 450W titanium model but I guess I asked for too much
