Final Words & Conclusion
Final Words & Conclusion
The Seasonic Vertex GX-1000W is an excellent product. The size is relatively compact (160 mm in length), so you won’t need a bigger chassis to make it fit without a problem. The exterior looks good (in all black), 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 disable. The unit comes with a 10-year warranty. It’s an 80 Plus Gold 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 1000 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 W power draw (in games).
On the quality side, all is great, and the stability tests also went well. Load regulation is very good for a mid-tier PSU, 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 80% load, so there’s no reason to complain. You get typical accessories in the package, including mounting screws, a power cord, cable ties (also the Velcro type), a sticker, and a manual. The provided cables come in a solid, flexible braided casing to neatly and beautifully place inside the PC case. There’s a 12-pin Gen 5 PCIe-compatible cable (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 Vertex GX-1000W (ATX 3.0) is over 93% (at 230 Volts). In the case of this particular unit, half of the maximum wattage is 500 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 Gold PSU like the Seasonic Vertex GX-1000W is an excellent and ultimate solution. The price is $ 199,99 / € 239,00 for the 1000 W variant, which is not extremely expensive 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 1000 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 Vertex GX-1000W approach with modular cables lets you plug in only the necessary leads, improving your build’s looks. The Vertex GX-1000 case looks nice; its finishing makes it look solid. 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 Vertex GX-1000W retails at $ 199,99 / € 239,00, which is rather steep, but you pay for the fantastic performance and the ATX 3.0 compatibility. The unit looks rather attractive and has compact dimensions (160x150x86 mm). 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 definitely more than satisfactory. The Seasonic Vertex GX-1000 offers great acoustics (as it becomes audible only above 80% load) and solid build quality. According to the standards, the efficiency is like it should be for the 80 Plus Gold award. You also get a 10-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. This PSU deserves the “Recommended” award for the ATX 3.0 compatibility and low noise under typical operating temperatures.
