One of the vital perks of normality in large part returning to the PC parts marketplace now that the crypto mining bubble has popped has been a large growth in element availability. Video playing cards had been after all the most important trade there – although costs on the newest technology stay upper than many want to see – however crypto farms had been additionally absorbing the whole lot from CPUs and RAM to chronic provides. So after a length of just about two years of high-powered PSUs of all flavors being onerous to come back via, the PSU marketplace is, finally, additionally returning to commonplace.

The cave in of crypto mining and underlying growth of electronics parts has additionally supposed that high-power PSU designs have reverted, in a way, to a extra balanced portfolio. PSU distributors are in spite of everything making some contemporary investments in high-end, high-efficiency designs – PSUs that crypto miners would have by no means paid the top rate for. Particularly with the release of the brand new ATX 3.0 usual and its 12VHPWR connector, there’s a possibility for a brand new technology of PSUs to make their mark whilst powering the newest video playing cards.

There are few chronic provides the place that is extra obvious than XPG’s new Fusion Titanium 1600. The only real member of its elegance to this point, the Fusion is a real flagship-grade PSU with the electronics high quality to check. Constructed via Delta Electronics, the XPG Fusion makes liberal use of Gallium Nitride MOSFETs as a way to ship a monstrous 1600 Watts of chronic at 80 Plus Titanium ranges of performance. All of the whilst this can be probably the most first high-powered ATX 3.0 chronic provides, providing two 12VHPWR connectors – making it appropriate to power two high-end video playing cards – which isn’t any small feat given the ability tour necessities that include the ATX 3.0 specification.

To that finish, nowadays we’re totally exploring the whole lot that makes the XPG Fusion stand proud of the gang. From its outsized chassis to its nearly absurd voltage law high quality, it’s an influence provide that few consumers will ever want, however surely makes its mark around the PSU design ecosystem.

Packaging and Package

We won the XPG Fusion in a big cardboard field that in an instant hints on the dimensions of the sizable PSU. The art work is fairly elementary, however the placing purple colour does no longer cross not noted. Fundamental efficiency and compliance data is imprinted on the facets and rear of the field. Within the field, the PSU is safe between thick packaging foam.

XPG, for the ones unfamiliar with the corporate, is the gaming emblem of ADATA Era, probably the most trade’s main PC portions providers. That gaming lineage (and anime mascot) makes for one thing of an atypical pairing for this explicit PSU, since in this day and age multi-GPU programs are nearly at all times skilled graphics and AI programs – the demise of SLI manner there is not any wish to pair up GPUs for gaming programs. Nonetheless, as ADATA’s gaming emblem, XPG has earned a name for turning in upper high quality merchandise than the ADATA emblem itself, so it makes numerous sense to make use of it to promote this top rate chronic provide. And studying issues rather extra cynically, it does not harm that for deep-pocketed players who can manage to pay for to construct a device that spares no expense, the Fusion offers XPG one thing to upsell the ones consumers on.

Bundled along the XPG Fusion, we discovered six cable straps, 4 mounting screws, and an AC chronic cable. The package deal could be very frugal for a manufactured from this worth vary however consideration must be given to the AC chronic cable, which has an IEC C19 connector as a substitute of the average IEC C13 connector. XPG was once compelled to make use of the C19 connector because the enter present of the PSU can surpass the rated present capability of the C13 connector.

Expectedly, the XPG Fusion is a completely modular design, bearing in mind the removing of each DC chronic cable, together with the 24-pin ATX connector. All the cables are totally black, with ribbon-like black wires and black connectors. Simplest the 24-pin ATX cable differs, which is sleeved. The Fusion Titanium 1600 is the primary PSU we’ve got noticed with two 12VHPWR connectors.

At this level, we will have to additionally point out the presence of a small “OC Hyperlink” cable. That cable can be utilized to daisy chain more than one XPG Fusion gadgets in combination, permitting them to perform concurrently. This clearly isn’t a function maximum customers will probably be fascinated by however one thing to attract the eye of customers development rendering and/or mining farms.

The XPG Fusion Titanium 1600 PSU

Exterior Look

In an technology the place each producer targets to design the smallest PSU conceivable, the XPG Fusion Titanium 1600 is almost profane.  The monstrous chassis is 210 mm lengthy and customers will undoubtedly need to double-check the clearances in their case to verify compatibility. Without reference to the scale of the case, standard ATX gadgets are 60-70 mm shorter, so there is also an obstruction that forestalls the set up of this sort of lengthy PSU.


The chassis of the Fusion Titanium 1600 is solely customized. It’s sprayed with a satin black paint this is very clean and lovely but additionally vulnerable to fingerprint marks. The fan finger guard is part of the chassis itself. Embossed geometrical shapes and patterns can also be discovered on each the ground and facets of the chassis. Ornamental stickers quilt part of each and every aspect and the sticky label with the unit’s electric certifications and specs covers a part of its best aspect.

A regular on/off transfer can also be noticed on the rear aspect of the unit, beside the ability connector. The ability connector is an IEC C20 as a substitute of the regularly discovered IEC C14. The entrance aspect of the unit is suffering from the connectors for the modular cables. There was once no longer a lot room left for a legend so XPG painted elementary headers immediately at the chassis and subsequent to each and every crew of connectors.


Inner Design

The fan chargeable for the cooling of the XPG Fusion Titanium is the Hong Hua HA13525H12SB-Z. Hong Hua is a longtime producer of high quality lovers, however we discovered no data on-line about this actual fashion. However, we established that it has a most pace of about 2450 RPM and it includes a twin ball bearing design. Those designs don’t seem to be the quietest however they’re essentially the most dependable, and XPG may no longer take dangers after backing up the unit with a 12-year guaranty.

XPG overtly advertises that the XPG Fusion Titanium is the end result in their collaboration with Delta Electronics, a extremely respected OEM with many years of revel in in chronic electronics. Despite the fact that we hardly ever see their designs in consumer-grade PC PSUs, Delta Electronics has been round for over 50 years and so they these days are probably the most biggest firms within the box, with R&D workplaces and factories international.

An insignificant look on the insides of the XPG Fusion Titanium 1600 PSU is sufficient for any individual with a elementary seize of the way standard PC PSUs are designed to appreciate that this unit is hugely other. Just like each different PC PSU, we begin with a filtering degree that is composed of six Y capacitors, two X capacitors, and two filtering inductors and ends up in a twin enter rectifying bridge configuration. The rectifying bridges don’t seem to be the standard variations that we most often in finding connected to a heatsink, however slightly two Infineon IPDQ60R010S7, which might be considerably extra environment friendly that standard bridge rectifiers. They’re put on a vertical board with no heatsink in any respect, just because their losses are so low there’s no want for a heatsink.


The APFC circuit is also other than what we most often come across. As a substitute of 2 MOSFETs and a diode, there are 4 MOSFETs and no diode (Totem Pole topology). Two large 450V/820μF capacitors from Rubycon and two massive encased coils shape the passive parts of the APFC. The lively APFC parts are on a 2nd vertical daughterboard subsequent to the brink of the unit with an aluminum heatsink connected immediately to them. The heatsink is actually touching the aspect of the unit so the airflow will probably be extraordinarily restricted however we suspect that the APFC MOSFETs (Gallium Nitride, Infineon IGT60R070D1) rarely want any cooling in any respect.


Shifting forward, the design will get ever extra distinctive. The principle inversion aspect is a fairly standard LLC resonant circuit, with the main distinction being the usage of 4 extraordinarily high-efficiency Gallium Nitride FETs. Those feed the spotlight of this platform, the planar transformer. We will be able to no longer be seeing planar transformers used on different platforms anytime quickly as they’re patented via Delta Electronics. Their number one benefit over conventional transformers is the extraordinarily excessive chronic density, as planar transformers can maintain the similar output inside not up to 1 / 4 of the distance required via standard transformers. This might be very to hand if Delta Electronics come to a decision to increase very high-density gadgets, but it surely arguably was once no longer a lot of a bonus right here, because the Fusion Titanium 1600 got here out extraordinarily lengthy anyway.

After the planar transformers, standard chronic MOSFETs generate the 12V line. There is just one main output, with the more than one 12V strains being the manufactured from more than one OCP protections. The present prohibit consistent with line can also be set by means of tool, or person OCP protections can also be disabled in choose of a unmarried large 12V rail. As anticipated, the secondary 3.3V and 5V strains are generated by means of DC-to-DC circuits. Massive bars switch the ability from the principle PCB to the PCB protecting all the connectors. All the secondary aspect capacitors are solid-state and are supplied via Nippon Chemi-Con.
