Seasonic Focus SGX-650 Power Supply review

We put the new Seasonic Focus SGX-650 power supply on our test bench today. It’s an SFX-L version of the Focus series, which has already become one of the most recommended PSUs on the market (even though it has had some compatibility issues with certain GPUs). The Seasonic Focus SGX-650 is a small form factor (SFX-L) power supply, but it’s still possible to install it in ATX systems. It has 80 plus Gold certification, which means that it’s 90% efficient at 50% load @ 110V, and even 92% efficient @ 230 V. The SFX format makes this model an interesting one for people with HTPC chassis. It seems that Seasonic has brought users an efficient, powerful, and reliable solution.

It’s a fully modular PSU, so even the motherboard connectors are not attached permanently (but you still have to use them, right?). This feature is not really necessary, as an increasing number of cases are now fitted with a power supply shroud, but it’s still easier to manage cables this way. The fan works in hybrid mode (semi-passive), so you should be able to achieve a very nice acoustic experience. What is quite surprising, is the size of the fan. It’s 120 mm, whereas the entire power supply measures just 125 mm. It’s the smallest PSU with this type of fan. It uses FBD bearings, and it’s controlled via a temperature sensor. The SGX-650 is built with 100% Japanese 105℃ capacitors, and they're a great choice for high-performance PCs where reliability is crucial.

There is also a variant with less power - a 450 W one. They’re both Gold Certified as well, which indicates at least 90% efficiency at 50% load (92% at 230 V). This is important, because the energy consumed does not go to waste (at least not in a significant amount), and this has an impact on your energy bill.

Seasonic’s Focus SGX-650 is backed by a 10-year warranty. This is a very good offer, as for example Corsair also offers 10 years for their higher-end series, whereas Seasonic itself provides even twelve years of warranty for their Prime series. MSRP Is about 130 EUR. Ok, let’s check this SFX-L 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.
