Final Words & Conclusion

The Seasonic Prime Titanium is an excellent product. But should it be a surprise, considering it was done based on Seasonic’s best platform? It’s Seasonic’s first ATX 3.0 compatible PSU, delivering 1600 W power while not too compact (210 mm). You would need a bigger chassis to make it fit without a problem. The exterior looks great (in all black, with silver fan grill), but the thing is that most of the chassis nowadays have a PSU shroud, which would hide this piece of art behind a metal. You can find the fanless mode here, which you can turn off. The unit comes with a very long, 12-year warranty. It’s an 80 Plus Titanium certified PSU, and that’s a great 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 1600 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 4090) rarely exceeds 650-700 W power draw (because this RTX has a 450 W power limit).

On the quality side, all is great, and the stability tests also went smoothly. Load regulation is great, and there was no noticeable droop on the +5V and +12V rails. Ripple suppression is safely within tolerance. The 135 mm fan 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 great bundle of accessories in the package, including mounting screws, a power cord, and a manual, but also velcro ties, zip ties, and angled ATX 24-pin adapter. There are two 12-pin Gen 5 PCIe-compatible cabless (capable of delivering 600 W).

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 1600W (ATX 3.0) is nearly 96% (at 230 Volts). In the case of this particular unit, half of the maximum wattage is 800 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) 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 is an over-the-top solution for most consumers. The price is ~530 USD for the 1600 W variant, which is high even for such a high-wattage PSU, but you get one of the best (if not the best) products in the market.

Stability
There isn’t much to say about stability. The voltages hold, and this doesn’t change under higher loads. The 1600 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-1600 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. Also, you get cable combs to make them look even better. Additionally, this makes the installation process relatively simple. The PRIME TITANIUM TX-1600 case looks very nice; its finishing makes it look very premium. Still, the PSU shroud 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 retails at ~530 USD. It is a steep price, but remember, 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-1600 offers excellent acoustics (as it becomes audible only above 85-90% load) and great build quality. According to the standards, the efficiency is as good as 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 cables for powering up to 600 W GPUs. The SEASONIC PRIME TITANIUM TX-1600 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. We think this PSU that has ATX 3.0 compatibility deserves the “Golden” 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) and due to the large dimensions (210 mm may not fit in a significant part of the chassis).
