With the 12VHPWR connector now compulsory for the newer NVIDIA RTX 40 series graphics cards, users are kind of being forced to embrace the new connector if they’re going for the upgrade. While NVIDIA and the partners did include an adapter together with the card so you can still use your existing power supply to power up the new RTX 40 series cards, the extra cables that are connected to the adapter can be a pain to deal with.
Users who prioritize cable management for the clean look will either have to opt for a custom-made cable for the power supply they’re using or just a brand new ATX 3.0 power supply that comes with a dedicated 12VHPWR cable. The FSP Hydro G Pro ATX 3.0 1000W that we have here today is one of the new ATX 3.0 power supplies that are ready for the new RTX 40 series cards you can get in the market. So without any further ado, let’s see what can we expect from the new FSP Hydro G Pro ATX 3.0 1000W.
|Input Voltage||100-240 Vac|
|Dimension||150 x 150 x 86 mm|
|Fan Type||FDB Fan, 120mm|
|Efficiency||80 PLUS Gold (90% at typical load)|
|Protection||OCP, OVP, OPP, SCP, OTP|
|Cable Type||Flat (except for 12VHPWR cable), All black|
As a new model that supports the 12VHPWR connector on the new NVIDIA RTX 40 series graphics cards, FSP specifically highlighted that on the box so you wouldn’t miss out on this important information while considering a purchase. For the Hydro G Pro ATX 3.0 1000W, you can expect it to full fill pretty much all the requirements to run any RTX 40 series cards, especially the RTX 4090 which can draw up to 600W+ if needed.
Aside from the 12VHPWR support, the Hydro G Pro ATX 3.0 1000W also features a fully modular design, an Eco switch that toggles the fan operation to achieve almost zero noise, and a complete series of protection that you can expect from a good power supply.
Inside the box, you’ll find the Hydro G Pro ATX 3.0 1000W, a power cord, a bunch of power cables, screws, and velcro straps. Among that bunch of power cables, you’ll find two of the standard 12V EPS cables, an ATX 24-pin cable, three PCIe 6+2-pin cables, a 12VHPWR cable, and five SATA power cables with two of the cables that have a mix of 4-pin Molex connector on it.
Now for the Hydro G Pro ATX 3.0 1000W, the design didn’t really change much and at first glance, it immediately reminds me of the Hydro G Pro 750W we’re currently using in one of our work systems. As the fan grill screws don’t have that warranty sticker on them that prevents you from doing an annual cleaning, it’ll be much easier to get rid of those dust chunks that have accumulated throughout the year if you know what you’re doing.
From the specs details label sticker, we can again see the capabilities of the Hydro G Pro ATX 3.0 1000W to support the latest NVIDIA RTX 40 series cards and probably other future graphics cards that use either the 12VHPWR cable or the other three PCIe 6+2-pin cables.
Moving on to the connectors, we can see that the layout is actually almost exactly the same as the Hydro G Pro 1000W except for second the PCIe 6+2-pin connector on the first row, which is now a 12VHPWR header. We also notice that FSP decided to tone down on the printed model name this time, ditching the slightly exaggerated design finally.
At the back of the power supply, you’ll find the standard honeycomb grille design for exhaust, and a switch to toggle the semi-fanless eco mode if you want the keep your system noise to the minimum during idle. Enabling eco mode will suspend fan operation until the load has exceeded 30%, a very useful feature for those who are into low-noise PC builds, allowing you to achieve virtually zero noise during low-load operation.

For basic usages such as light gaming, web browsing, and some basic entertainment, the total system power draw never really exceeds 300W. The highest temperature recorded on light usage is at about 48°C and you can barely hear any fan noise coming from the power supply fan, but then again, other moving parts in your system will probably make louder noise than the power supply fan by the time it finally starts spinning.
We have also done a series of tests using benchmark suites such as the ROG RealBench, Cinebench R23, Prime95, 3DMark, and Procyon to have a better look at what the Hydro G Pro ATX 3.0 1000W is capable of during load. Throughout the tests we have conducted, the total system power draw observed during the tests is around the range of 660-740W, which is still within what the Hydro G Pro ATX 3.0 1000W is capable of and we still have a pretty comfortable headroom right there. The highest temperature observed during load is at about 67°C, which is within the safe range as seen in the technical specifications.
While the Hydro G Pro ATX 3.0 1000W is technically an upgraded version of the Hydro G Pro 1000W, it’s not really easy to justify the RM 829 price tag if you don’t really need the 12VHPWR support. As both power supplies have the same 80 PLUS Gold rating and the most notable difference now is the 12VHPWR support which is still optional as of today because AMD still releases their new graphics card with PCIe 6+2-pin. And if you prefer the Radeon RX 7000 series cards over the GeForce RTX 40 series cards, I’d say the Hydro G Pro 1000W is still a better option because of its lower price which is in the lower RM600 range.
Don’t get me wrong here, both the Hydro G Pro ATX 3.0 1000W and Hydro G Pro 1000W are very well designed by FSP but because the 12VHPWR has yet to become mainstream, I will still recommend the Hydro G Pro 1000W to those who don’t need the 12VHPWR connector. As for users who are eager to upgrade to the GeForce RTX 40 series graphics cards, especially the RTX 4090 which I consider the most powerful consumer graphics card to date, the Hydro G Pro ATX 3.0 1000W is one solid power supply I wouldn’t even hesitate to recommend.
