Final Words & Conclusion

Final Words & Conclusion

The Seasonic Prime Titanium TX-1300 is a great product. The size is not compact (210 mm in length), so you’ll need a bigger chassis to make it fit without a problem. You can find the fanless mode here, which you can disable, and it would still be a quiet power supply unit. The exterior looks very nice, but the thing is that most of the chassis nowadays have a PSU shroud, which would hide this piece of art behind a metal. The unit comes with a 12-year warranty. It’s an 80 Plus Titanium certified PSU, and that’s a typical choice for even the high-end systems (maybe a bit more) from the consumer’s point of view (in terms of efficiency/price of the unit). The 1300 W variant offers a massive power output that should be enough for most users, even the most elaborate gaming setups, with a single graphics card in their system. A PC like the one used in this test (i9 13900K + Geforce RTX 3080) rarely exceeds 500-550 W of power draw.  On the quality side, all is great, and the stability tests also went well. Load regulation is excellent, and there was no noticeable droop on the +5V and +12V rails. Ripple suppression is safely within tolerance. The 135 mm fan (from Champion ) does well when it’s supposed to spin. It becomes audible close to 85-90% load, so there’s no reason to complain. You get a lovely set of accessories in the package, including mounting screws, a power cord, and a manual (so a rather typical set), but also, there are velcro straps and chassis stickers. The provided cables come in a solid and flexible braided casing to neatly and beautifully place inside the PC case. There’s a 12-pin Gen 5 PCIe compatible cable with 16-pins (12+24), which should support even a 600 W GPU power draw.  

A word about efficiency

Like with any other power supply, 50% of the maximum load is where the device is most efficient. The sweet spot of the Seasonic Prime Titanium TX-1300 is a bit under 96% (at 230 Volts). In the case of this particular unit, half of the maximum wattage is 650 W. The average gaming PC with a single graphics card (at least those usually spotted in Steam hardware polls) won’t exceed this value under normal conditions. Don’t overestimate the savings (on your electricity bill) that you can make by going from 80 Plus Bronze to even Titanium. You can assume that the build quality of more expensive PSUs will be higher, but the differences in efficiency are not that significant. So, summing it up, an 80 Plus Titanium PSU like the Seasonic Prime Titanium TX-1300 is an excellent and ultimate solution. The price is about 460 EUR for the 1300 W variant, which is expensive, even for a high-wattage PSU.

Stability

There isn’t much to say about stability. The voltages hold, and this doesn’t change under higher loads. The 1300 W version should be enough for a single GPU (who uses the dual-GPU these days, without SLI support?) like an RTX 4080/4090, even with an Intel Core i9 13900K.

Aesthetics

This Seasonic PSU looks nice with its all-black cabling. The Seasonic Prime Titanium TX-1300 approach with modular cables lets you plug in only the leads you need, improving your build’s looks. All connectors are individually sleeved cables, including the SATA and Molex cables. Still - in the sample, we got the 12VHPWR cable with a braided sleeve (in the ones sold now - it should be with a braid pattern). Also – you get cable combs, so you can make them look even better. Additionally, this makes the installation process relatively simple. The PRIME TITANIUM TX-1300 case looks very nice; its finishing makes it look very premium. Still, the PSU shroud that you’ll usually have or the compartment for the power supply at the back of the motherboard tray wouldn’t help. A few chassis will allow the appropriate presentation. 

Final words

The SEASONIC PRIME TITANIUM TX-1300 retails at 460 EUR, a steep price, but you need to remember that it’s a premium-level product designed for overclocking and gaming enthusiasts. The unit looks attractive (typically for the Prime series). Speaking of which, it’s a pity that you won’t even see the PSU in most of the chassis, as it would be hidden behind the shroud or at the back of the motherboard tray, so in most cases, that effort wasn’t so much needed. As for the power delivery itself – there’s no reason to be worried, Seasonic has made the platform, and the results are fantastic. The SEASONIC PRIME TITANIUM TX-1300 offers excellent acoustics (as it becomes audible only above 85-90% load) and great build quality. According to the standards, the efficiency is like it should be for the 80 Plus Titanium award. You also get a 12-year warranty, which you would expect in that price range. You also get the 12+4-pin PCIe 5.0 compatible cable for powering up to 600 W GPUs. One remark here -> in the sample, we got the 12VHPWR cable with a braided sleeve (in the ones sold now - it should be with a braid pattern). The SEASONIC PRIME TITANIUM TX-1300 is a great option for hardcore Seasonic fans, but you need to dig deep in your pocket, which is the biggest drawback. Still - thanks to its outstanding performance, it stands out in the market. It’s applicable, especially for the noise (or lack of it in most scenarios), but not only. You can find the PSU tester in the bundle, the cable combs, and even a 65W USB Type-C charger! We think this PSU deserves the “Top Pick” award, but not for everyone due to the pricing (and not everyone would need it, especially when not possessing GPUs like RTX 3090Ti/4080/4090), lack of (official) ATX 3.0 compatibility, and due to the large dimensions (210 mm may not fit in a significant part of the chassis).
