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.

    I have the same problem on two computers with totally different hardware. Only in Chrome and Edge.

    Same for me, on desktop Opera (Chromium based).

    Thanks for the heads up, gang. I personally run Firefox and Safari as my daily drivers, so I'm not always seeing browser-specific issues.

    For those of you experiencing issues, could you please email me with more details on the browser you're using, screenshots, whether you're running any extensions, etc? I'd like to be able to replicate this so that we can properly hammer out a solution.

    I too have had this happen randomly, but only on my desktop PC (also using Chrome). It has never happened on my tablet or phone which is where I usually read AT.

    This PSU appears to fit into the category of "good enough" for OEMs and average consumers based on it's performance and price point. Since it seems to be "out of stock" most of the time they are probably just offering excess production to consumers as they achieve a higher profit margin by doing so.

    Depending on your needs this might be a suitable choice if you can actually buy it. It might be useful to compare costs of some of the high end PSUs along with warranty as they can typically offer better performance over a longer warranty period. Either way a quality PSU can pay dividends if you need reliability and PC performance because component life can last longer with better power quality.

    10yrs warranty, Good enough for your general usage, good pricing, eh i say there's no better choice atm.

    FSB continues to make solid power supplies for the price point. I have long used them in medium-end builds for others because they are reliable and not overpriced, though I use Seasonic in my own builds (without much apparent benefit).
