Cold Test Results (~22°C Ambient)

For the testing of PSUs, we are using high precision electronic loads with a maximum power draw of 2700 Watts, a Rigol DS5042M 40 MHz oscilloscope, an Extech 380803 power analyzer, two high precision UNI-T UT-325 digital thermometers, an Extech HD600 SPL meter, a self-designed hotbox and various other bits and parts. For a thorough explanation of our testing methodology and more details on our equipment, please refer to our How We Test PSUs - 2014 Pipeline post, as well as our addendum on ATX 3.0/12VHPWR testing.

The FSP Hydro G Pro 1000W manages to reach efficiency levels that would grant it an 80Plus Gold certification regardless of the input voltage. This is rare, as most manufacturers aim to meet the certification requirements with an input voltage of 115 VAC, where the required efficiency figures are lower. It has an average nominal load range (20% to 100% of the unit's capacity) efficiency of 91.8% when powered from a 230 VAC source, which drops down to 89.3% when powered from a 115 VAC source. The efficiency gap between the two input sources is quite high, suggesting that the design has been optimized for an 230 VAC input. Nevertheless, this design has very good low and high load efficiency, which also suggests that minor tweaks could easily have it reaching 80Plus Platinum levels with an 115 VAC input voltage.

We ran our tests with the Eco mode disabled, meaning that the fan began spinning instantly when the PSU was powered on. The fan runs at very low RPM while the load is up to 400 Watts, which also is most of the range that the Hydro G Pro could operate without relying on its fan at all (enabling the Eco mode will keep the fan from spinning until the load reaches 300 Watts). However, when the load is greater than 450 Watts, the speed of the fan keeps increasing alongside with the load, reaching figures above 50 dB(A) while the PSU is operating at maximum capacity. The internal temperature of the PSU remained very low at all times, suggesting that the designer favored reliability over acoustics.

    Crmaris, pretty much the guys who is making most of the PSU reviews lately on many sites like Tomshardware, provided a good review on Hardwarebuster. You can find the screenshot there of the latest chart of the ATX 3.0 offering. Overall, the FSP Hydro is not a great PSU at all. I made a good summary and on a post, and so far it seems that Be Quiet Dark Power 13 will be the only obvious choice.

    Anyway, the offering is sad if you are looking for an ATX 3.0 PSU.

    FSP Hydro is the worst of the ATX 3.0 offering so far
    MSI ai1300p is overpriced like hell
    Thermaltake GF3 is noisy like a turbo jet
    Silverstone Hela 1200R is also noisy and only offering 5 years of warranty
    Seasonic Vertex is between a Focus and a Prime
    Be Quiet Dark Power 13 only offer up to 1000W

    Just so you know, the image you linked displays an image that says, "Stop, this image was hot-linked," instead of whatever chart you intended. Once again, websites break peoples' attempts at educating others.

    Just go on Hardwarebuster and compare the latest ATX 3.0 chart from the Siverstone Hela 1200R review at the bottom of the page. The FSP PSU is last.

    97.16% isn't so far from 100% that I'd call something "the worst." If it meets the AXT 3.0 spec, and it does, then I'd say it's a valid offering.
  • DanNeely - Thursday, January 19, 2023 - link

    Agreed. Also the 100% score is for a platinum model; and you'd expect those to score slightly higher than more affordable gold models.

    This offering seems pretty squarely aimed at mainstream ATX 3.0 given the design and where it falls short. Everything I've seen on the market so far seems to cost a fair bit more (at regular prices at least) in the 1000W category with ATX 3.0.

    This dude making stupid claims, implying the PSU are "Worst" out of all psu in existence, pretending like this PSU unusable, even cramaris says This PSU are good enough not "OMG UNUSABLE" like your comment implying.

    @Anandtech: I've noticed this in every article now, but always thought it was something on my end. When scrolling through the articles, every once in a while, all of the text will become bold. It makes it nearly unreadable. Sometimes scrolling back up fixes it, sometimes a refresh, sometimes highlighting some text also brings it back to normal. The reason I know it is NOT me, is because before this was occurring on Chrome on my old computer; and now it is happening in Edge on a *brand new* computer.
  • ballsystemlord - Thursday, January 19, 2023 - link

    Give them the version number of your Edge browser and MS windows installation. They'll need that to try and reproduce the problem. Likewise with your Chrome install if you still have that.
  • NextGen_Gamer - Thursday, January 19, 2023 - link

    It was Windows 10 2H22, and now Windows 11 2H22. Every Chrome and Edge version from 104 or so onwards.
