The XPG Fusion Titanium 1600 PSU Evaluation: Outrageous Energy, Excellent High quality

One of many perks of normality largely returning to the PC elements market now that the crypto mining bubble has popped has been a return to regular as regards to element availability. Video playing cards had been after all the most important change there – even when costs on the most recent technology stay larger than many want to see – however crypto farms had been additionally absorbing every thing from CPUs and RAM to energy provides. So after a interval of virtually two years of high-powered PSUs of all flavors being laborious to come back by, the PSU market can be returning to regular.

The collapse of crypto mining and underlying enchancment of electronics elements has additionally meant that high-power PSU designs have reverted, in a way. PSU distributors are lastly making some recent investments in high-end, high-efficiency designs – PSUs that crypto miners would have by no means paid the premium for. Particularly with the launch of the brand new ATX 3.0 normal and its 12VHPWR connection, there’s a possibility for a brand new technology of PSUs to make their mark whereas powering the most recent video playing cards.

There are few energy provides the place that is extra obvious than XPG’s new Fusion Titanium 1600. The only real member of its class so far, the Fusion is a real flagship-grade PSU with the electronics high quality to match. Constructed by Delta Electronics, the XPG Fusion makes liberal use of Gallium Nitride MOSFETs so as to ship a monstrous 1600 Watts of energy at 80 Plus Titanium ranges of effectivity. All of the whereas this can even be one of many first excessive powered ATX 3.0 energy provides, providing two 12VHPWR connectors – making it appropriate to drive two high-end video playing cards – which isn’t any small feat given the facility tour necessities that include the ATX 3.0 specification.

To that finish, at present we’re completely exploring every thing that makes the XPG Fusion stand out from the gang. From its outsized chassis to its nearly absurd voltage regulation high quality, it’s an influence provide that few prospects will ever want, however actually makes its mark throughout the PSU design ecosystem.

Packaging and Bundle

We acquired the XPG Fusion in a big cardboard field that immediately hints on the dimensions of the sizable PSU. The art work is comparatively fundamental, however the placing purple colour doesn’t go unnoticed. Fundamental efficiency and compliance data is printed on the perimeters and rear of the field. Contained in the field, the PSU is protected between thick packaging foam.

XPG, for these unfamiliar with the corporate, is the gaming model of ADATA Expertise, one of many business’s main PC elements suppliers. That gaming lineage makes for one thing of a pairing for this particular PSU, since nowadays multi-GPU methods are nearly at all times skilled graphics and AI methods – the dying of SLI means there is not any must pair up GPUs for gaming methods. Nonetheless, as ADATA’s gaming model, XPG has earned a fame for delivering larger high quality merchandise than the ADATA model itself, so it makes loads of sense to make use of it to promote this premium energy provide. And studying issues barely extra cynically, it would not damage that for deep-pocketed players who can afford to construct a system that spares no expense, the Fusion provides XPG one thing to upsell these prospects on.

Bundled alongside the XPG Fusion, we discovered six cable straps, 4 mounting screws, and an AC energy cable. The bundle may be very frugal for a product of this value vary however consideration must be given to the AC energy cable, which has an IEC C19 connector as a substitute of the widespread IEC C13 connector. XPG was 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, permitting for the elimination of each DC energy cable, together with the 24-pin ATX connector. All the cables are utterly black, with ribbon-like black wires and black connectors. Solely the 24-pin ATX cable differs, which is sleeved. The Fusion Titanium 1600 is the primary PSU we’ve seen with two 12VHPWR connectors.

At this level, we also needs to point out the presence of a small “OC Hyperlink” cable. That cable can be utilized to daisy chain a number of XPG Fusion items collectively, permitting them to function concurrently. This clearly isn’t a characteristic most customers might be involved with however one thing to attract the eye of customers constructing rendering and/or mining farms.

The XPG Fusion Titanium 1600 PSU

Exterior Look

In an period the place each producer goals to design the smallest PSU potential, the XPG Fusion Titanium 1600 is virtually profane.  The monstrous chassis is 210 mm lengthy and customers will certainly must double-check the clearances of their case to make sure compatibility. Whatever the dimension of the case, typical ATX items are 60-70 mm shorter, so there could also be an obstruction that stops the set up of such an extended PSU.


The chassis of the Fusion Titanium 1600 is completely customized. It’s sprayed with a satin black paint that may be very easy and delightful but in addition liable to fingerprint marks. The fan finger guard is part of the chassis itself. Embossed geometrical shapes and patterns could be discovered on each the underside and sides of the chassis. Ornamental stickers cowl half of every facet and the sticker with the unit’s electrical certifications and specs covers a part of its prime facet.

A typical on/off swap could be seen on the rear facet of the unit, beside the facility connector. The ability connector is an IEC C20 as a substitute of the generally discovered IEC C14. The entrance facet of the unit is plagued by the connectors for the modular cables. There was not a lot room left for a legend so XPG painted fundamental headers straight on the chassis and subsequent to every group of connectors.


Inside Design

The fan liable for the cooling of the XPG Fusion Titanium is the Hong Hua HA13525H12SB-Z. Hong Hua is a longtime producer of high quality followers, however we discovered no data on-line about this explicit mannequin. Nonetheless, we established that it has a most pace of about 2450 RPM and it contains a twin ball bearing design. These designs should not the quietest however they’re essentially the most dependable, and XPG couldn’t take dangers after backing up the unit with a 12-year guarantee.

XPG overtly advertises that the XPG Fusion Titanium is the end result of their collaboration with Delta Electronics, a extremely respected OEM with a long time of expertise in energy electronics. Though we hardly ever see their designs in consumer-grade PC PSUs, Delta Electronics has been round for over 50 years and so they at the moment are one of many largest corporations within the discipline, with R&D places of work and factories worldwide.

A mere look on the insides of the XPG Fusion Titanium 1600 PSU is sufficient for anybody with a fundamental grasp of how typical PC PSUs are designed to understand that this unit is vastly completely different. Very like each different PC PSU, we begin with a filtering stage that consists of six Y capacitors, two X capacitors, and two filtering inductors and results in a twin enter rectifying bridge configuration. The rectifying bridges should not the everyday variations that we normally discover connected to a heatsink, however quite two Infineon IPDQ60R010S7, that are considerably extra environment friendly that typical bridge rectifiers. They’re positioned on a vertical board with no heatsink in any respect, just because their losses are so low there isn’t a want for a heatsink.


The APFC circuit is also completely different than what we normally encounter. As a substitute of two MOSFETs and a diode, there are 4 MOSFETs and no diode (Totem Pole topology). Two large 450V/820μF capacitors from Rubycon and two giant encased coils kind the passive elements of the APFC. The energetic APFC elements are on a second vertical daughterboard subsequent to the sting of the unit with an aluminum heatsink connected on to them. The heatsink is actually touching the facet of the unit so the airflow might be extraordinarily restricted however we suspect that the APFC MOSFETs (Gallium Nitride, Infineon IGT60R070D1) hardly want any cooling in any respect.


Shifting forward, the design will get ever extra distinctive. The first inversion facet is a comparatively typical LLC resonant circuit, with the most important distinction being the usage of 4 extraordinarily high-efficiency Gallium Nitride FETs. These feed the spotlight of this platform, the planar transformer. We won’t be seeing planar transformers used on different platforms anytime quickly as they’re patented by Delta Electronics. Their major benefit over conventional transformers is the extraordinarily excessive energy density, as planar transformers can deal with the identical output inside lower than 1 / 4 of the house required by typical transformers. This might be very helpful if Delta Electronics resolve to develop very high-density items, however it arguably was not a lot of a bonus right here, because the Fusion Titanium 1600 got here out extraordinarily lengthy anyway.

After the planar transformers, typical energy MOSFETs generate the 12V line. There is just one main output, with the a number of 12V traces being the product of a number of OCP protections. The present restrict per line could be set by way of software program, or particular person OCP protections could be disabled in favor of a single huge 12V rail. As anticipated, the secondary 3.3V and 5V traces are generated by way of DC-to-DC circuits. Giant bars switch the facility from the principle PCB to the PCB holding all the connectors. All the secondary facet capacitors are solid-state and are offered by Nippon Chemi-Con.
