The XPG Fusion Titanium 1600 PSU Review: Outrageous Power, Outstanding Quality
by E. Fylladitakis on March 30, 2023 8:00 AM ESTHot Test Results (~45°C Ambient)
Typical PSU designs take an overall performance hit when they operate in hot ambient temperatures. The XPG Fusion 1600 almost was an exception to that rule, with the unit almost entirely unfazed by the >25C temperature increase. The average efficiency drop is less than 0.15% across the nominal load range, suggesting that the components were hardly affected at all by the higher ambient and operating temperatures. There is practically no effect even when the unit is loaded to 100% capacity.
The main component temperatures of the XPG Fusion Titanium initially seem to be in line with typical high-performance PSU designs but one needs to decipher these graphs closely. Comparisons need to be made at the same level of power output and the maximum output of this unit is 1600 Watts. At an output of 800-1000 Watts and with its large chassis and extremely high efficiency giving it a gigantic advantage, the XPG Fusion Titanium foreseeably maintains very low operating temperatures, significantly lower than most 800-1000 Watt PSUs. The temperature can climb at over 100 Celsius when the unit operates at maximum load but without any palpable consequence.
The very high efficiency of the XPG Fusion Titanium allows it to mostly maintain the same cooling profile, even in this adverse operating environment. There is little difference to the fan’s speed or noise when the load is up to 900 Watts, even though the ambient temperature is far greater than before. At high loads, where the temperature rises alarmingly high, the unit seems to be ignoring the stock cooling profile and shoots the fan at maximum speed a little sooner than before. The fan will be very loud in these conditions but no unit is efficient enough to operate silently inside a hotbox and still reliably output up to 1.6 kWs.

It's unfortunate that it is so long as it prevents use in many if not most PC cases.TheinsanegamerN - Monday, April 3, 2023 - link
What century are you from? "most" cases LMFAO. Most PC cases today are gigantic and can easily handle a PSU like this.hubick - Thursday, March 30, 2023 - link
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.https://www.anandtech.com/show/12645/the-corsair-a...

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.pistonsmatter - Tuesday, April 4, 2023 - link
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.DigitalFreak - Saturday, April 1, 2023 - link
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.
