The ATX 3.0 PSU standard has been here since last year and while PCI-SIG has released the new ATX 3.1 specifications, the good thing is that they will be compatible with the existing designs. As such, we thought about giving you a tour of two brand-new ATX 3.0 PSUs from Enermax and XPG that we recently got our hands on and might just be a perfect build for your new PC. More details on the ATX 3.0 and ATX 3.1 standards can be found here and here.
Enermax Revolution D.F.X 1050W 80 Plus Gold PSU Specifications
So starting with our first unit, we have got the Enermax Revolution D.F.X 1050W 80 Plus Gold unit which is an 80+ Gold design with a power rating that should be more than enough for today’s high-end PC components. It’s a fully modular design like the rest of the Hydro series units we tested and comes in the standard 140x150mm form factor with a hint of RGB.
Coming to the specifications, the Enermax Revolution D.F.X 1050W 80 Plus Gold unit we got offers a maximum DC output of 1050 Watts. It’s an 80 PLUS Gold unit with efficiency rated at greater than or over 87% at 100% load. The PSU is fully compliant with Intel’s C6 & C7 power states and has an operating temp of up to 40C. The PSU has an input voltage of 100-240V and an input current rating of 13-6.5A.
Some protection features that you get on the FSP Hydro Ti Pro series PSUs include:
- Over Voltage Protection
- Under Voltage Protection
- Over Power Protection
- Over Temperature Protection
- Over Current Protection

According to Enermax, the D.F.X ATX 3.0 PSUs come with less than 200ms power-on time and can sustain 200% power excursions on the latest hardware. That’s a 1200W power excursion when taking into account up to 600W designs for some RTX 4090 GPUs but we have seen in reality that the card doesn’t hit power spikes that high and mostly averages around 400-450W in gaming workloads.
The cooling is provided by a top-mounted dust-free rotation fan which measures 120mm. The fan comes with a high-pressure blade design and also offers a semi-fanless mode where the fan will only spin if the PSU load exceeds 20% or goes over temperature. There’s also a 6-pole motor inside the fans with 3 phases that provide minimal vibration for silent operation.
Some main features of the Enermax D.F.X ATX 3.0 PSU series include:
- Intel ATX 3.0 & PCIe 5.0 Ready
- Fully Modular 80 PLUS® Gold Certified
- Native 600W PCIe 5.0 / Gen 5 12+4 Pin 12VHPWR Cable
- Extra Dual PCIe 8 Pin to 12+4 Pin 12VHPWR Cable
- Up to 200% Power Excursion and Instant Power-on Time
- 6-pole Motor Fan Inside
- RGB Control Button for ON/OFF and 14 lighting Modes
- Dust-Free Rotation Tech. for Ultra Cleanness
- Semi-Fanless Tech. for Absolute Silence Under 20% Load

XPG Core Reactor II 850W 80 Plus Gold PSU Unboxing & Close-Up
The XPG Core Reactor II comes in a large red-colored package with a picture of the PSU on the front along with the XPG brand ambassador, Mera (an anime character).
The back side also offers a list of features which we have detailed above. You can see the various cables and connectors that come with the package along with its specifications.
Opening the package reveals the PSU itself, along with a pouch that includes all the cables and connectors, and case stickers.
The PSU itself is packaged in a plastic cover.
This is a 140mm chassis which makes it really small and easier to manage within crammed-up PC cases. The exact dimensions of the PSU are 140x150x86mm.
Keeping the design simple, we get the power-in plug and the power on/off switch at the back. The large exhaust vents are also here to push hot air out of the PSU chassis.
Now depending on how you use the PSU, the bottom panel reads the specifications and power ratings. The PSU is rated to output a maximum of 70.8A and 850W through the 12V rails.
The sides of the PSU have the XPG Core Reactor II labels.
Coming to the connectors, there are 1 PCIe 12+4 (12VHPWR), five PCI-e 6+2-pin connectors, an ATX 24-pin (14+10 pin) connector, and two 4-pin Molex connectors.
The cables within the packaging pouch include the ATX 20+4 pin, a Gen5 connector, two 8-pin CPU connectors, 4 PCIe 8-pin connectors, and 3 Peripheral connectors.
Lastly, we have the 120mm fan which has various profiles that enable it to run in quiet mode when the load is low and ramp up the fan speed when required.
Impressions
Both Enermax and XPG have some nice ATX 3.0 PSU offerings out now which are available in various wattage options. With prices of $124.99 US for the XPG Core Reactor II 850W & $179.99 US for the Enermax D.F.X 1050W, these two are decent options for your new PC builds which feature a 10-year warranty. Knowing that PSU is one component in PC builds that generally lasts the longest without the need to upgrade, it’s better to invest in something that will stick with you for a couple of years.
The ATX 3.0 standard may not be a requirement now but considering where things are headed with power usage, it’s better to invest in something that’s more future-proof.
