The XPG Fusion Titanium 1600 PSU Review: Outrageous Power, Outstanding Quality

Now that the cryptocurrency mining bubble has burst, one of the perks of sanity that has largely returned to the PC component market is the return to normality in terms of component availability. Video cards have been the biggest change, of course, even if prices for the latest generations have remained higher than many would like, but crypto farms have also absorbed everything from CPUs and RAM to power supplies. So, after almost two years of hard-to-find strong PSUs of any flavor, the PSU market is also returning to normal.

The collapse of cryptocurrency mining and the underlying improvement in electronic components also means that, in a way, high-power PSU designs are back on track. PSU vendors are finally making new investments in high-end, highly efficient designs. This is a PSU that cryptocurrency miners never paid a premium for. In particular, with the launch of the new ATX 3.0 standard and its 12VHPWR connection, there is an opportunity for the new generation of his PSU to turn heads while powering the latest video cards.

Few power supplies are more obvious than XPG’s new Fusion Titanium 1600. The only member of this class so far, the Fusion, is a true flagship-grade his PSU that matches the quality of the electronics. Built by Delta Electronics, the XPG Fusion makes extensive use of Gallium Nitride MOSFETs to deliver a massive 1600 Watts of power at 80 Plus Titanium levels of efficiency. All the while, it was one of the first high power ATX 3.0 power supplies, offering two 12VHPWR connectors. This makes it suitable for driving two high end video cards. 3.0 spec.

That’s why today we’re delving into everything that makes XPG Fusion stand out from the crowd. From the oversized chassis to the almost ridiculous voltage regulation quality, it’s a power supply most customers don’t need, but it’s certainly made a name for itself throughout the PSU design ecosystem.

packing and bundling

I received the XPG Fusion in a large cardboard box with the dimensions of the large PSU readily apparent. The artwork is relatively basic, but the striking red color doesn’t go unnoticed. Base performance and compliance information is printed on the side and back of the box. Inside the box, the PSU is protected by thick packing foam.

XPG is the gaming brand of ADATA Technology, one of the industry’s leading PC component suppliers. That gaming pedigree goes something like this particular pairing for his PSU. Because modern multi-GPU systems are almost always professional graphics and AI systems. The demise of SLI means you don’t need to pair a GPU for your gaming system. Still, ADATA’s gaming brand, XPG, has a reputation for offering higher quality products than the ADATA brand itself, so using XPG to market this premium power supply makes a lot of sense. It is fulfilled. Reading a little more cynically, for wealthy gamers who can afford to build a system they’re willing to pay, Fusion wouldn’t hurt to give his XPG something to upsell to those customers.

I found 6 cable straps, 4 mounting screws, and 1 AC power cable that came with XPG Fusion. The bundle is very spartan for a product in this price range, but we should note his AC power cable, which features an IEC C19 connector instead of the common IEC C13 connector. XPG was forced to use a C19 connector because the PSU’s input current could exceed the rated current capacity of his C13 connector.

As expected, the XPG Fusion is a fully modular design, allowing all DC power cables to be removed, including the 24-pin ATX connector. All cables are completely black with black ribbon-like wires and black connectors. Only the sleeved 24-pin ATX cable is different. The Fusion Titanium 1600 is his first PSU with two 12VHPWR connectors.

At this point, I should also mention the existence of a small “OC Link” cable. This cable can be used to daisy chain multiple XPG Fusion units to work simultaneously. This is obviously not a feature that most users will be interested in, but it is of interest to those building render or mining farms.

In an era where all manufacturers aim to design the smallest PSU possible, the XPG Fusion Titanium 1600 is effectively blasphemy. The huge chassis is 210mm long and users should double check the case clearance to ensure compatibility. Regardless of the size of the case, a typical ATX unit is 60-70mm shorter, so there may be obstacles preventing the installation of such a long PSU for him.

The Fusion Titanium 1600 chassis is completely custom. It’s sprayed with a satin black paint that’s very smooth and beautiful, but prone to fingerprint marks. The fan finger guard is part of the chassis itself. Embossed geometric shapes and patterns are found on both the bottom and sides of the chassis. Decorative stickers cover half of each side, and stickers with the unit’s electrical certifications and specifications cover part of the top surface.

A typical on/off switch is on the back of the unit next to the power connector. The power connector is IEC C20 instead of the common IEC C14. The front of the unit is littered with connectors for modular cables. There wasn’t much room for a legend, so XPG painted basic headers directly onto the chassis and placed them next to each group of connectors.

internal design

The fan responsible for cooling the XPG Fusion Titanium is the Hong Hua HA13525H12SB-Z. Hong Hua is an established manufacturer of high quality fans, but I couldn’t find any information online about this particular model. I have confirmed that These designs aren’t the quietest, but they’re the most reliable, and XPG couldn’t take a risk after backing the unit with his 12-year warranty.

XPG openly touts the XPG Fusion Titanium as the result of a collaboration with Delta Electronics, a highly respected OEM with decades of experience in power electronics. While their designs are rarely seen in consumer PC PSUs, Delta Electronics has been around for over 50 years and is now one of the largest in the field with R&D offices and factories worldwide. Enterprise he is one.

One look inside the XPG Fusion Titanium 1600 PSU, and if you have a basic understanding of how a typical PC PSU is designed, you’ll notice that this unit is very different. Like all other PC PSUs, it starts with a filtering stage consisting of 6 Y capacitors, 2 X capacitors, and 2 filtering inductors, leading up to a dual input rectifier bridge configuration. The rectifier bridge is two Infineon IPDQ60R010S7 instead of the typical version usually mounted on a heatsink and is significantly more efficient than a typical bridge rectifier. They are placed on vertical boards without any heatsinks at all, simply because they have very low losses and don’t need heatsinks.

APFC circuits are also different from what we usually see. Instead of two MOSFETs and one diode, there are four MOSFETs and no diodes (totem pole topology). Two huge Rubycon 450V/820uF capacitors and two large cased coils form the passive components of the APFC. The active APFC components are on a second vertical daughterboard at the edge of the unit, with aluminum heatsinks attached directly. The heatsink literally touches the sides of the unit, so airflow is very restricted, but the APFC MOSFET (Gallium Nitride, Infineon IGT60R070D1) seems to require little cooling.

As we move forward, the designs become more and more unique. The primary inverting side is a relatively typical LLC resonant circuit, the main difference being that he uses four very efficient gallium nitride FETs. These feed the highlight of this platform, the planar transformer. Patented by Delta Electronics, soon you won’t see planar transformers used in other platforms. The main advantage over conventional transformers is their very high power density. A planar transformer can handle the same output in less than a quarter of the space required by a typical transformer. This could come in very handy if Delta Electronics decides to develop a very high density unit, but the Fusion Titanium 1600 has been out for so long that it probably doesn’t offer much of an advantage here. bottom.

After the planar transformer, a typical power MOSFET produces the 12V line. There is only one primary output and multiple 12V lines are the result of multiple OCP protections. Per-line current limits can be set in software, or individual OCP protections can be disabled in favor of a single massive 12V rail. As expected, the secondary 3.3V and 5V lines are generated through DC-DC circuits. A large bar transfers power from the main PCB to the PCB that holds all the connectors. All secondary capacitors are solid state and made by Nippon Chemi-Con.
