Final Words & Conclusion

The FSP Hydro PTM X Pro is a very good product. It’s not the first FSP’s ATX 3.0 compatible PSU, so there was no surprise that it performed as expected. Despite delivering 1000 W power (there are also 850 and 1200 variants), it is very compact (130 mm in length). You don’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. The inside has a coating against dust/stains and humidity. You can find the fanless mode here (active till ~30% load, so here it’s 300 W), which you can turn off. The unit comes with a very long, 10-year warranty. It’s an 80 Plus Platinum certified PSU, and that’s an excellent choice for even the high-end systems 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 650-700 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 120 mm fan does well when it’s supposed to spin. It becomes audible at nearly 70% load, so there’s no major reason to complain (but it cannot be silent enough for some). You get a very decent bundle of accessories in the package, including mounting screws, a power cord, and a manual, but also velcro ties and forced start connectors. There is one 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 FSP Hydro PTM X Pro 1000 W (ATX 3.0) is nearly 94% (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) will rarely 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 Platinum PSU like the FSP Hydro PTM X Pro can be an over-the-top solution for most consumers. The price is ~245 USD for the 1000 W variant, which is a decent offer for such a high-wattage PSU, especially since it’s very compact (usually, the competitors are 5-7 cm longer.

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 FSP PSU looks nice with its all-black cabling. The FSP Hydro PTM X Pro approach with modular cables lets you plug in only the necessary leads, improving your build’s looks. All connectors are ribbon-like except the classic sleeve on the PCIe 5.0 12WHPWR cable. The HYDRO PTM X PRO 1000 W case looks nice. 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 FSP Hydro PTM X Pro 1000 W retails at ~245 USD. It is a reasonable price for a very compact, high-end product (130 mm in length) with 100% Japanese brand capacitors. The unit looks good; the chassis has textured paint (which should be resistant to fingerprints). The inside has a coating against dust/stains and humidity. Speaking of looks, 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 as expected. The FSP HYDRO PTM X PRO offers good acoustics (as it becomes audible only above 70% load) and a very good build quality. According to the standards, the efficiency is as good as it should be for the 80 Plus Platinum 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. The FSP HYDRO PTM X PROTX-1300 is a nice option for not only hardcore FSP fans. Still - thanks to its very compact size (130 mm long), it stands out in the market. We think that overall - this PSU that has ATX 3.0 compatibility deserves the “Silver” award.
