The Hydro G Pro is the upgrade of the popular Hydro G series from FSP and as a Hydro G 650W user myself, I’m actually really looking forward to this. We manage to get our hands on the Hydro G Pro 750W this time for a quick overview, so let’s see what FSP has to offer and will it be able to handle our usual test system with a GeForce RTX 3080.

Unboxing

The packaging design is very similar to the Hydro G series but with a slight change to the product presentation on the box. Features of the power supply, as well as the connectors of the cables included, can be found at the back of the box. Though the one that really caught my attention is the warranty period, which is now 10-year long as compared to the 5-year warranty on the previous Hydro G series.

Inside the box, you’ll find the FSP Hydro G Pro 750W, label stickers for the power supply in case you don’t like the plain look on the stock label stickers, and all the cables you need for your build.

The overall design is pretty simple but I do appreciate the brought surface texture, which I am personally very fond of as compared to those smooth surfaces. If you have previously seen the Hydro G series fan grill design, you can immediately tell the difference here, which covers more area on the opening for intake.

The power output as according to the label has an impressive +12V rail that can output 62.5A, which will suffice for quite a lot of high-end graphics cards of the current time, notably the GeForce RTX 3080 and Radeon RX 6800 XT.

While it’s still a fully modular design power supply just like its predecessor, we can see that the FSP Hydro G Pro 750W now has two sockets for CPU instead of one, which is great for the newer motherboards with more than one 8-pin EPS connector to supply more power to the CPU.

At the back of the power supply unit, you’ll find the familiar-looking 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.

User Experience

CPU Intel Core i9-11900K @5GHz
Motherboard ASUS ROG Maximus XIII Apex
Memory Teamgroup T-Force Dark Z FPS
Graphics Card NVIDIA GeForce RTX 3080
Power Supply FSP Hydro G Pro 750W
Primary Storage Kingston KC2000 1TB NVMe SSD
Secondary Storage WD Black 6TB
CPU Cooler ASUS ROG Ryujin II 360
Chassis Cooler Master MasterFrame 700
Operating System Windows 10 64bit

We started off with the basic synthetic stress test with various stress test utilities such as FurMark GPU stress test tool, ROG RealBench, Cinebench R23, Prime95 for 1 hour each. The total system power draw observed during the tests is around the range of 530-560W and the FSP Hydro G Pro 750W seems to be able to handle the load pretty well. The average temperature of the unit is around 47ºC most of the time during load, which is within the safe range as seen in the technical specifications. The fan noise is somehow audible at some point during the load test but it won’t be an issue if you’re a headphone user.

Moving on to long hours of stress tests and actual usage, the Hydro G Pro 750W did really well throughout the test period and we have yet to notice any signs of failure or hiccups at the moment. Even for some stress tests which we just left the system running for the entire day, the highest temperature observed on the unit is at about 48ºC.

Verdict

Despite its higher price tag at RM 519, the Hydro G Pro 750W performs remarkably on our test system. We can’t say it’s going to be the same for heavier tests with high-precision hardware that is specially made just for power supply load test but at least it didn’t give us any issue throughout our basic tests. The only downside for the Hydro G Pro 750W is probably the limited PCIe power socket of two, which can be an issue for some users with a graphics card that requires more than two PCIe power cables.

As for the more common system setup, the Hydro G Pro 750W is a pretty reasonable choice for most use cases. The flat cables and fully modular design, insanely long 10-year long warranty are some of the features FSP has to offer with this power supply, and honestly, I don’t have many negative comments for the  Hydro G Pro 750W.
