XPG Fusion 1600 Titanium: Platform-Powering Perfection?
The power supply industry doesn’t appear to move quickly until you look closely enough to see that its slow creep forward happens in tiny jumps. Efficiency and quality rating companies such as 80 Plus and Cybenetics are responsible for much of this movement as these certifications give buyers an inkling of marketing claim credibility.

While most reviews focus on the Fusion 1600 Titanium’s planar transformer and Gallium Nitride FET as manufacturer Delta’s new hybrid design, we’ve enough faith in the Cybenetics rating process that we’re really just interested in how well this model might fit into an upgrade strategy for our current internal component test platform: Its ability to support two 12VHPWR-powered graphics cards certainly puts it over the top, and its ATX 3.0 compliant 3670W power excursion (100μs) means that we’ll never want for power no matter how we load up our machine.
Big graphics support doesn’t end with the dual 12VHPWR connectors either, as the case includes six connectors for the now-legacy 6+2 pin PCIe supplemental power connector. And that’s without giving up either of the two 4+4 pin EPS12V/ATX12V cables. And, an included pair of splitter cables (center, below) allows builders to connect a pair of twin 6+2 pin PCIe connector cards to the power supply’s two 12VHPWR jacks, should they not have any cards that require the newer connector.
FYI: The “OC Link” connector (second cable from bottom) allows users to trigger the power on function of a second power supply from the main power supply, and the “Prime Port” header’s cable (bottom, below) feeds power supply data to XPG’s Prime ecosystem software via a motherboard’s 9-pin USB 2.0 internal header.
Like most power supplies that are rated past 1000W, the Fusion 1600 Titanium uses an IEC C20 connector rather than the more common C13. Often rated by cable manufacturers at 20A and 15A respectively, we were surprised to find that IEC only rates these as supporting 16A and 10A (we’re assuming IEC’s ratings include a rather large safety factor).
100% of the Fusion 1600 Titanium’s power is available through its 12V rails, and any power you send to 5V or 3.3V devices must be deducted from those rails.
Speaking of non-12V devices, our Fusion 1600 Titanium included two ATA to Floppy style drive power adapters, despite the web page stating it had only one “floppy” output. The four-pin power plug features a single 5V and a single 12V lead, in addition to two grounds.
Today’s test pits the XPG Fusion against the Dark Power Pro 850W we’re hoping to replace, in addition to the venerable AX860i of our cooler test rig and the XG 750 Plus Platinum of our case testing kit.

Here’s the rest of our build: We were amazed to see it pulling around 730 to 740 watts after ten minutes loaded, and didn’t want to run it too much longer at this high a stress level due to the 13900K’s tendency to die during extended use.

One thing to note was the that XPG Prime software appeared to be misreporting our power use, at least according to other instruments, by up to 4%. The voltage and thermal reports appeared accurate though, so take what you see here with only a pinch or less of salt (though we never got the unit hot enough to kick the fan to full speed).
All of our current test units are only 80 Plus Platinum rated, and you shouldn’t be surprised to see a Titanium-rated power supply that’s only running at around half-load to do so at higher efficiency than a fully-loaded Platinum-rated part. The most surprising result from its Platinum-rated competitors is that second place goes to the one stressed closest to its power limit.
You might have noticed that we didn’t do anything all that special here, because we don’t have the specialty equipment to challenge Cybenetics’ rating for the unit. The simple test we did run showed greater efficiency at 120V compared than Cybenetics reached at 115V, but our test conditions were also a bit gentler to the unit. And that efficiency, which exceeded 94%, deserves some recognition.

Unfortunately, the above description is all the extra recognition we can give the unit. It is, after all, no better a bargain than most of its competitors, and a 94% efficiency finding isn’t uncommon on Titanium-rated parts. That is to say, while the XPG Fusion 1600 Titanium is probably the perfect unit for our upgrade, its merely one of several products that you should probably consider before making so large a purchase.
