Introduction

We would like to thank FSP for supplying the review sample.



FSP is one of the largest PSU OEMs with close ties to some of the major PSU companies, including be quiet! and EVGA. Their latest release is the Hydro G series consisting of three members with capacities of 650 W, 750 W, and 850 W. According to FSP, these PSUs are mostly for gamers and modders because of their exchangeable side stickers and nice externals. The Hydro G models use a high-end platform with Japanese capacitors and an FDB (Fluid Dynamic Bearing) fan. All of these also feature 80 PLUS Gold efficiency, come with a fully modular cabling design, and a semi-passive option, which will help keep noise output low at light and mid loads.

The HG750 will be on our test bench today. This unit belongs to a highly popular wattage category strong enough to feed a powerful gaming system equipped with two VGAs. Its capacity also allows it to offer good efficiency at light loads, an area where higher capacity units usually aren't as efficient. High-end GPUs were very demanding until only recently and could, as such, only be run with high-capacity PSUs, but that changed with NVIDIA's Maxwell GPUs that consume much less than previous high-end GPUs or most of AMD's current offerings. The HG750 will be enough for a SLI system with two GTX980s and a strong CPU that won't bottleneck the system. Only should you decide to build a strong Crossfire system will you need a PSU with a capacity of 1 kW or more ; that is, if you plan on overclocking those cards.

Specifications

The HG750 is 80 PLUS Gold certified, Haswell ready, and capable of delivering its full power continuously at up to 50°C. Every protection feature is present, and it has a high quality FDB fan that is backed by a semi-passive operation for less noise output at light loads. 17 cm deep, this PSU is a little larger than usual, but it weighs very little without any cables attached. FSP also provides a decently long warranty, although its MSRP is quite high, which puts the HG750 into the same category as such offerings as the EVGA SuperNova 750 G2 and Corsair RM750x. The competition is very strong and the HG750 had better perform very well overall in order to be a competitive alternative to such offerings.


With 62.5 A maximum current output, the +12V rail is strong enough for a gaming system. At 150 W maximum combined output where most PSUs in this category deliver only up to 100-120 W on these rails, the minor rails are very strong as well. Capable of 3.5 A output, the 5VSB rail is also quite strong. It is nice to see PSUs with beefy 5VSB rails, especially since modern tablets need lots of juice to charge.

Cables & Connectors, Power Distribution

Cable length is satisfactory, and the distance between peripheral Molex connectors is good enough. However, some would prefer less space between the SATA connectors. The HG750 has a large number of peripheral connectors, including twelve SATA and six 4-pin Molex connectors, and its four PCIe connectors are enough for its capacity. Our only complaint here is the single EPS connector as you will have to use an adapter with a motherboard that has two EPS sockets or an EPS and ATX12V socket. All the cables mostly use 18AWG wires, which is the standard.

Since this PSU features a single +12V rail, we do not have anything to comment on when it comes to its power distribution.

Packaging

The box sports a nice graphics design and is strong enough to provide good protection. At its front, FSP showcases the changeable stickers, and there are a series of icons in the bottom-left corner for the 80 PLUS Gold efficiency, semi-passive operation, fully modular design, and Japanese caps. In the opposite corner are the capacity description and five year warranty icon, and another icon that most likely stands for the PSU's compatibility with Intel's Broadwell CPUs.


A scheme on this side describes all available connectors. Unfortunately, there is no information on each cable's length, which would be useful, especially to us reviewers.


The power specifications table can be found here, along with two graphs for the efficiency and fan-speed curves.


FSP has an app for Android OS devices. They should make one for iOS devices as well.


There is an interesting scheme of the PSU's internals on the back of the box, providing information on the technologies used. There is also a pretty long features list on this side.

The contents inside the box are protected very well.


A small box includes the bundle consisting of the modular cables, two Velcro straps, a set of fixing bolts, two sets of stickers, the user's manual, and another leaflet.
