Seasonic Connect 750 W PSU review

We’re putting the new Seasonic Connect power supply on our test bench today. It was introduced to the market on the 4th of March, after a long wait (they first presented it two years ago, at Computex 2018). It’s a brand new approach to the desktop PSU idea. Why’s that? Because this time you don’t receive everything integrated into a single unit, but two “modules” instead. One is a Seasonic PRIME 750 W 80 PLUS Gold certified power supply, and the other is the CONNECT device, which is essentially a backplane that is mounted to the PC case with magnets to provide connections for all the components. You need only two cables to link these segments together. The Seasonic Connect is an 80 Plus Gold power supply, which means that it’s 90% efficient at 50% load @ 115 V, and even 92% efficient @ 230 V. This is important because the energy consumed does not go to waste (at least not in a significant amount), and that affects your energy bill. The Seasonic Connect is an ATX power supply (but not a typical one, as I’m sure you’ve realized by now).

It’s a fully modular PSU but in a far different way than what you might be used to from other products. Even the motherboard connectors are not attached permanently to the housing, but you still have to use most of them anyway. Nearly all cases have a power supply shroud now (at least ATX-sized ones do), but that’s not really needed in this case, as the whole cable management process takes place behind the motherboard tray. This time, the most important aspect is the amount of space on the “dark side”. So far, there are no other variants than the 750W (SSR-750FA). This one should be enough for most users, but we still hope that this series will be expanded. The fan is a 135 mm Fluid Dynamic Bearing one (it should be long-life). The unit can work in fanless (hybrid) mode until 40% load, so it should stay totally passive even with loads up to 300 W (and that is the power consumption of something like a Ryzen 5/Core i5 + RTX 2060/RX 5700), but there’s also a mode in which the fan spins continuously.

The Connect is built with Nippon 105℃ capacitors that provide enhanced reliability and durability. The main unit itself is quite small, measuring 150 mm x 85 mm x 140 mm. On the other hand, the Connect module is 328 mm x 20 mm x 63 mm, which might create some compatibility issues for a big percentage of PC cases available on the market because you need to have 28 mm clearance behind the motherboard tray. Seasonic’s Connect is backed by a 10-year warranty. This is a great offer, even though this brand provides as many twelve years of warranty for their Prime series. The best part is that, at 169.99 USD, the reviewed product is not much more expensive than a regular Prime Gold PSU (the difference is only about 20 USD).

But sure, let’s check out this innovative PSU from Seasonic, shall we?

Seasonic Vertex GX-1000 - 1000W ATX 3.0 PSU review
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.
