Cold Test Results (~22°C Ambient)

For the testing of PSUs, we are using high precision electronic loads with a maximum power draw of 2700 Watts, a Rigol DS5042M 40 MHz oscilloscope, an Extech 380803 power analyzer, two high precision UNI-T UT-325 digital thermometers, an Extech HD600 SPL meter, a self-designed hotbox and various other bits and parts. For a thorough explanation of our testing methodology and more details on our equipment, please refer to our How We Test PSUs - 2014 Pipeline post.

Most manufacturers target their designs to meet the 80Plus certification requirements with an input voltage of 115 VAC due to the lower standard requirements. The XPG Fusion 1600 does meet the 80Plus Titanium requirements with an input voltage of 115 VAC, reaching a top efficiency of 94.7% and an average nominal load range (20% to 100% of the unit's capacity) efficiency of 93.5%. Switching the input voltage to 230 VAC does increase its average efficiency to 94.1%, but the improvement is not substantial enough to meet the 80Plus Titanium standard thresholds. Nonetheless, the XPG Fusion 1600 undoubtedly is highly efficient, especially when the load is very low, which is crucial with a product with that high a power output.

The stock cooling profile of the XPG Fusion 1600 is well-balanced between performance and acoustics, albeit a bit aggressive at higher loads. We can see that the fan turns on and spins slowly, practically inaudibly, as long as the load is low. It is very impressive that the fan hardly speeds up at all while the load is below 50% and that, in this case, is an output of 800 Watts. Any typical gaming PC would not be capable of forcing the XPG Fusion Titanium to substantially increase its fan speed. When the load is higher than 800 Watts, the losses are enough to warrant a faster fan speed, with the control circuit speeding up the fan as the load increases. The profile is programmed to shoot the fan at maximum speed, even though the temperature readings do not warrant that. Users can also adjust the cooling profile via the software.

    It's unfortunate that it is so long as it prevents use in many if not most PC cases.

    What century are you from? "most" cases LMFAO. Most PC cases today are gigantic and can easily handle a PSU like this.

    Woulda been nice to see a comparison against my older Corsair AX1600i. I'll keep this one in mind for my next build.
  • E.Fyll - Thursday, March 30, 2023 - link

    I intentionally avoided that because the AX1600i is not ATX 3.0 compliant. A basic comparison can be done though by cross-checking the two reviews.

    Mining is back with Kaspa, so big PSUs are still a nice thing to have for those that mine. Outside of mining, having PSUs over 1Kw are also becoming a necessity. New Sapphire Lake-X CPUs are power monsters, The RTX 4080 and 4090 are monsters.
    I have an overclocked i9-10920X and RTX 4090, as well as a few NVMe drives, a several 10TB HDDs, and a bunch of fans, and I hit over 1200w during both gaming and creative workloads. My EVGA 1000w PSU is a beast though, and my KiloWatt meter sometimes shows a draw up to around 1250w from the wall during the heaviest draws without ever hitting OCP.
    Makes me want a PSU rated for around 1300-1600w.

    Soon people will be tripping breakers.

    You're only allowed to pull 1,440 watts from a 120V 15a breaker over any period of time, so this PSU is not safe to run on a 15A outlet which is what >99% of people will have available to them in the USA.

    The sooner governments start making cryptocurrency unprofitable the better.
  • PeachNCream - Tuesday, April 4, 2023 - link

    I am reluctant to encourage government intervention, but in the case of cryptocurrencies I agree. They're used by criminals to hide transactions and gullible people tag along for a variety of poorly thought out reasons, enriching criminal enterprises and equipment sellers scamming delusional miners.
  • pistonsmatter - Tuesday, April 4, 2023 - link

    Keep in mind you cannot pull more than 1,440 watts from a 15a breaker in the USA or it will eventually trip, don't forget things like your monitor use as much as 200 watts in some cases.
