Seasonic Connect 750 W PSU review -
Final Words & Conclusion
Final Words & Conclusion
The Seasonic Connect series is a great addition to the market. It’s based on the revised Focus platform (although Seasonic calls it Prime), and is 80 plus Gold certified. It comes with a 10-year warranty. It’s also nice that 105°C-rated capacitors have been used. Seasonic introduced the Connect module here. Was it a good idea? It was a brave one, for sure. Well, the concept is very good and unique, and this solution should make it possible. All you need is to have more than 20 mm clearance behind the motherboard tray (it’s best to have 28 mm, which is not the standard). If that requirement is fulfilled, then the installation should go smoothly. Splitting the main unit from the connection module allowed Seasonic to achieve more clearance for the PSU's internals, which provides better airflow there. Even the 750 W variant should be enough for most users with a single graphics card in their systems. In reality, a setup like the one used for the daily testing (i9 9900K + Geforce RTX 2080 Ti) rarely exceeds 400 W of power draw.
On the quality side, all is good, and the efficiency (on par with 80 Plus Gold declarations) and stability tests went nicely as well. Load regulation is excellent, and there was no noticeable droop on the +5V and +12V rails. Ripple suppression is well below tolerance levels. The 135 mm fan does its job well. It becomes audible close to 75% load, so there’s some room for improvement there (maybe in another revision?).
You can clearly see that Seasonic engineers have done a tremendous job with this PSU, took full advantage of the concept, and really made it work as it should! As a bonus, you get a nice set of accessories, including mounting screws, Velcro straps, a bag for the cables, a manual, etc.
A word about efficiency
Same as with any other power supply, 50% of the maximum load is where the device is at its most efficient. At this sweet spot, the Seasonic CONNECT achieved a bit over 90% (at 230 Volts). In the case of this particular unit, half of the maximum wattage is 375 W. The average gaming PC with a single graphics card (at least the ones that are usually spotted in Steam hardware polls) won’t exceed this value under normal conditions. Don’t overestimate the savings (electric bill) that you can make by going from 80 Plus Bronze to even Titanium. You can assume that the build quality of a more expensive PSUs will be higher, but the differences in efficiency are not that significant. So, summing it up, an 80 Plus Gold PSU like the Seasonic Connect reviewed here is a perfect solution. The price is about 169.99 USD for the 750 W variant, which is really reasonable.
Stability
There really isn’t much to say about stability. The voltages hold even under higher loads. The 750 W version should be enough even for dual-GPU setups with cards like an Nvidia Geforce GTX/RTX 1070/2070 or single GPU like RTX 2080 Ti.
Aesthetics
The Seasonic PSU looks very nice with its all-black cabling. The Connect solution with modular cables lets you plug in only the leads that you really need, and this will certainly improve the looks of your build. Additionally, this makes the installation process is quite simple.
Final words
The Connect retails at 169.99 USD, which is a good price, and only a 20 USD premium over the similar Prime 750 W Gold model (although the internals of the Connect is actually closer to the Focus series, which is still good). It offers sleek looks, even though nowadays it’s most likely to be hidden inside a shroud, good acoustics (could have been a bit better at 75%+ load), and very good build quality. The efficiency is like it should be (80 Plus Gold). You also get a 10-year warranty and a nice set of accessories. Implementation of the Connect module leaves almost nothing to be desired, except maybe for slightly improved compatibility (a bit thinner module if possible). The fan’s RPMs also could use a bit of optimization for higher loads, as it becomes audible close to 75% of the rated wattage. Other than that, we do recommend this PSU. It’s an innovative, quality product at a good price. All things considered, remember to check the clearance behind your motherboard tray as you will need a bit of space..

Today we’re putting the new Seasonic Vertex GX-1000W power supply on our test bench. The company is mainly known for its PSUs (like the Prime series, which we checked, for example, the TX-1300) and the chassis (like the Arch Q503 or Syncro Q704). The Vertex series is a new one from Seasonic that was launched in September 2022, but with the availability specified for January 2023. It consists of 80 Plus Platinum or Gold efficiency and has the following wattage variants: 1200 W, 1000 W (which we’re checking in an 80 Plus version), 850 W, and 750 W.
Seasonic Prime Titanium TX-1300 (1300W PSU) review
Today we’re putting the new Seasonic Prime Titanium TX-1300 power supply on our test bench. The company is mainly known for its PSUs (like Connect or Focus SGX), but we also already checked their two chassis (Q704 and Q503). Still, the high-end offer in the power supply range is the Prime series. The series debuted in 2016, but the TX-1300 and TX-1600 were released in July ’22. Both are not ATX 3.0 compatible (this will come in mid-December with a Vertex PSU family). Still, one of the new things introduced in the Prime Titanium TX-1300/TX-1600 (but also the 80 Plus Platinum compatible PX-1300/PX-1600 models) is the PCI Express® 5.0 compatible 12+4-pin power cable. Although the TX-1300 is a new PSU featuring two 12VHPWR connectors, it still isn’t ATX 3.0 compatible. You get a 16-pin capable of providing up to 600 W (12+4). So what does it mean exactly? Geforce RTX 30xx/40xx Founders Edition will work with Prime Titanium TX-1300 PCIe Gen5 connectors simply because they do not need more than 450W. The other versions of RTX 4090 – can get more than that, which should work too.
Seasonic Arch Q503 chassis + Connect PSU review
Seasonic company is known mainly for its power supplies, including the Focus (available in ATX and SFX factor), Prime (with the 80 Plus certificate up to Titanium), or Connect series. But that’s not all, as we already had a chance to check out their first chassis last year – Syncro Q704 with a 750W power supply. It has earned a “Recommended” award. It was an inverted ATX case, but we got something more traditional this time. It’s a Seasonic Arch Q503, which was presented in May ’22. This model should be cheaper; however, it was also designed more conventionally. It uses a two-chamber structure, with the mainboard tray sitting on the right side of the case.
Seasonic Syncro Q704 chassis + Connect PSU review
Seasonic company is known for its great power supplies, including the Focus (available both in ATX and factor), Prime (with the 80 Plus certificate up to Titanium), or Connect series. Speaking of the last one, they’ve gone further by introducing a chassis containing this piece of hardware – it’s a Seasonic SYNCRO Q704. But that’s not all – according to the marketing information, it really fits together, literally and figuratively.
