With the ATX 3.0 period now effectively underway, we have been having a look on the first era of ATX 3.0 energy provides to hit the market. Introducing the 16-pin 12VHPWR connector, which may provide as much as 600 Watts of energy to PCIe playing cards, ATX 3.0 marks the beginning of what’s going to be a gradual shift out there. As high-end video playing cards proceed to develop in energy consumption, energy provide producers are working to meet up with these traits with a brand new era of PSUs – not solely updating energy provides to satisfy the height vitality calls for of the most recent playing cards, but in addition to raised deal with the massive swings in energy consumption that these playing cards incur.
For our second ATX 3.0 energy provide, we’re taking a look at a unit from FSP Group, the Hydro G Professional ATX 3.0. Not like a number of the different ATX 3.0 PSUs we have checked out (and might be taking a look at), FSP has taken a barely totally different method with their first ATX 3.0 unit: fairly than modifying its greatest platform or releasing a brand new top-tier platform, FSP went with an improve of its hottest platform, the unique Hydro G Professional. As such, the brand new Hydro G Professional ATX 3.0 1000W PSU does not have particularly spectacular specs on paper, however it boasts good all-around efficiency for an reasonably priced price ticket ($199 MSRP). That makes FSP’s platform notable at a time when most ATX 3.0 include an early adopter tax, with FSP clearly aiming to entice mainstream customers who could not presently want an ATX 3.0 PSU however want to personal one in case of future upgrades.

As a real Authentic Machine Producer (ODM) that designs, develops, and sells their very own PSUs, this type of iterative technique is one we have seen from FSP earlier than, and one which has historically served them effectively. For instance, virtually 9 years glided by between our evaluation of the Aurum PT sequence and the newer Hydro PTM sequence. As in that case case in addition to now with the Hydro Professional G, FSP likes to develop confirmed designs that they’ll supply to shoppers and downstream OEMs alike for a few years to return. All of which implies that when FSP does replace or overhauls a platform, it is for an excellent cause – and usually warrants being attentive to.
Packaging and Bundle
We obtained the FSP Hydro G Professional ATX 3.0 1000W PSU in a hanging cardboard field, with a further cardboard ribbon round it. The field may be very sturdy and, on the within, further packaging foam slabs and a nylon bag shield the unit from transport injury. A wealth of details about the unit and its new PCIe 5.0 12WHPWR connector may be discovered on each facet of the field, which goes to be very useful for brick-and-mortar prospects specifically in order that they’ll keep away from complicated this PSU with the unique (non-ATX 3.0) Hydro G Professional.
Contained in the field we discovered a bare-bones equipment bundle, a notable alternative contemplating that that is for a flagship-level PSU. The corporate provides solely a easy AC energy cable, 4 mounting screws, and a fundamental guide. There are additionally two units of facet stickers, one inexperienced, and one pink. The blue set is already glued to the unit. These stickers are everlasting and can’t be eliminated with out damaging them.
The FSP Hydro G Professional 1000W PSU is a totally modular design, permitting for the elimination of each DC energy cable, together with the 24-pin ATX connector. Almost all the cables are black, ribbon-like, with black connectors. The one exception lies with the PCIe 5.0 12WHPWR cable, which is also all-black, however it’s a traditional sleeved cable as an alternative.
FSP’s entrepreneurs have printed on the field that the 12WHPWR cable is rated for as much as “9.2 A per contact, with all 12 energy contacts”. Sadly, that finally ends up being deceptive alternative of phrases, because it implies that every one 12 contacts can ship present to the cardboard. Every of the ability contacts of the 16-pin connector is certainly able to dealing with 9.2 A, however there are solely six voltage and 6 floor contacts. Which implies that the cable has a most steady present supply capability of 6 × 9.2 A, which totally conforms with Intel’s design necessities.

The FSP Hydro G Professional ATX 3.0 1000W PSU
Exterior Look
The FSP Hydro G Professional ATX 3.0 1000W is fairly compact for a 1 kW unit, with a chassis that’s simply 150 mm deep. It’s technically not totally compliant with the ATX customary dimensions, which restrict the depth of an ATX PSU to 140 mm, however 150 mm mustn’t pose any issues in any fashionable ATX case. FSP sprayed the chassis with textured paint, which is aesthetically interesting and virtually proof against fingerprints. The fan finger guard is a separate however customized half, with the corporate emblem adorning its heart.
The sticker with the unit’s electrical certifications and specs covers about half the highest facet of the PSU. Ornamental blue-themed stickers are pre-applied on the edges of the unit, which may be changed with the pink or inexperienced stickers that FSP contains within the bundle. The draw back right here is that the stickers might be destroyed as soon as eliminated, making any alternative technically everlasting.
A typical on/off change may be seen on the rear facet of the unit, beside the ability connector. One other small change proper subsequent to it controls the “ECO Mode” of the cooling fan. When activated, the cooling fan will shut off whereas the load is beneath 300 Watts. The entrance facet of the unit is house to the quite a few connectors for the modular cables. A really delicate legend is printed beneath every group of connectors, sprayed instantly onto the chassis.
Inner Design
FSP as soon as once more entrusted the cooling of their PSU to Protechnic Electrical, a model we normally discover taking good care of the cooling wants of their PSUs. The MGA12012XF-O25 is a 120 mm fan with a fluid-dynamic bearing (FDB) engine and a particularly excessive most rotational velocity of 2700 RPM.
As we talked about above, there are not any hidden ODMs to find right here – FSP is each the designer and the producer of the Hydro G Professional 1000 Watt PSU. A swift have a look at it reveals that it’s primarily based on these days frequent topologies and tools, with the corporate clearly aiming for simplicity and reliability.
The filtering stage is textbook, with a complete of 4 Y capacitors, two X capacitors, and two filtering inductors resulting in a twin enter rectifying bridge configuration. Each of the rectifying bridges have their very own heatsink sandwiched in between them. The passive APFC elements are a big 450V/680μF APFC capacitor by Nippon Chemi-Con and a big filtering coil wrapped inside a protecting foil. The lively APFC elements are on an extended heatsink proper throughout the sting of the PCB.
Two transistors type a typical half-bridge inversion topology on the main facet of the unit, whereas six MOSFETs positioned on the underside of the PCB generate the 12V line on the secondary facet of the transformer. The three.3V and 5V traces are being generated through the DC-to-DC conversion circuits. All in all, it is a very typical configuration for an 80Plus Gold licensed unit. All the secondary capacitors, electrolytic and polymer alike, are offered by Nippon Chemi-Con and Rubycon, each Japanese producers.
