Final Words & Conclusion

The FSP Hydro G Pro 1000W (ATX 3.0) is a good product. The size is compact (150 mm in length), so you won’t need a bigger chassis to make it fit without a problem. 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. You can find the fanless mode here, which you can disable, and it would still be a quiet power supply unit. 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 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 120 mm fan (from Protechnic Electric) does well when it’s supposed to spin. It becomes audible close to 75-80% 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. 

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 FSP Hydro G Pro 1000W (ATX 3.0) is a bit over 92% (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) 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 Gold PSU like the FSP Hydro G Pro 1000W (ATX 3.0) is an excellent and ultimate solution. The price is about 190 USD for the 1000 W variant, which is not so expensive for a high-wattage PSU. 


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.


This FSP PSU looks nice with its all-black cabling. The FSP Hydro G Pro 1000W (ATX 3.0) approach with modular cables lets you plug in only the leads you need, improving your build’s looks. The HYDRO G PRO 1000W (ATX 3.0) case looks nice; its finishing makes it look very solid. 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 FSP HYDRO G PRO 1000W (ATX 3.0) retails at 190 USD, which is not a steep price; it’s relatively good for a higher-end product designed for overclocking and gaming enthusiasts. The unit looks rather attractive and has compact dimensions (150x150x85 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, FSP has made the platform, and the results are more than satisfactory. The FSP HYDRO G PRO 1000W (ATX 3.0) offers very good acoustics (as it becomes audible only above 70-75% 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. We think this PSU deserves the “Approved” award.
