FSP Hydro G Pro 1000W ATX v3.0 Power Supply Review

FSP Hydro G Pro 1000W ATX v3.0 Power Supply Review

The FSP Hydro G Pro 1000W has top-notch build quality and it is ATX v3.0 and PCIe 5.0 ready.

The FSP Hydro G Pro 1000W has top build quality and compact dimensions. Its performance is decent, and the native 600W 12VHPWR connector will come in handy if you invest in a new NVIDIA GPU.

The FSP Hydro G Pro 1000W is among the few Gold PSUs in this capacity category featuring ATX v3.0 and PCIe 5.0 compatibility. Its performance is decent, but it isn’t high enough to allow it to earn a place in our best PSUs article. Competitors like the Corsair RM1000x and the EVGA 1000 G7 achieve notably higher overall performance scores.

The Hydro G Pro with 1000W max power belongs to the new generation of PSUs, featuring ATX v3.0 and PCIe 5.0 compatibility. There aren’t many choices with native 12VHPWR connectors in the 1000W Gold category, and FSP was among the first to introduce a related product.

Significant players, including Corsair, EVGA, and Seasonic, haven’t released something on the market, yet. Thermaltake, with the Toughpower GF3 1000W, and Silverstone, with the DA1000R Gold, are two other choices in this category, meeting the ATX v3.0 spec for PSUs with 12VHPWR connectors.


With 150mm depth, the Hydro G Pro 1000 has compact dimensions. Nonetheless, FSP has the smallest, in dimensions, 1000W Gold platform, which is used in the EVGA 1000 G7, with only 130mm depth! Compact PSUs are easier to install, especially in smaller chassis, but the over-populated PCBs don’t help airflow, hence noise output is usually increased.


Moreover, it is not possible to install large enough cooling fans, with 135mm or 140mm diameter, in small PSUs, and smaller fans have to spin at higher speeds to offer the same airflow, producing more noise. The Hydro G Pro uses a 120mm, high-quality, fan, featuring a fluid dynamic bearing.

The cables are long, and the amount of connectors is satisfactory. The single 12VHPWR connector can deliver up to 600W. According to Intel’s test plan, a 1000W ATX v3.0 PSU should be equipped with a 450W 12VHPWR connector, but most brands don’t pay attention to this and use 600W connectors to make sure that the NVIDIA RTX 4090 graphics cards can go all the way up to 600W. Not all 4090s have such high maximum power limits, though.

The small PCB is equipped with equally small heat sinks. Except for the transient filter, the other circuits have enough space between electronic parts to allow for decent airflow. It is good to see the filtering caps on the secondary side being on the clear, without anything blocking airflow to them.

Typically, for an FSP platform, we find some potentiometers on a vertical PCB, which might look tempting to adjust, but you should not do it! The build quality is high, and all parts that FSP used are of high quality, too. FSP is among the few OEMs using bulk caps rated for 3,000h @ 105°C. All other brands use 2,000h @ 105°C bulk caps
