The electrical performance of the XPG CYBERCORE II 1300W PSU is very good, although not in any way extraordinary for a unit of this class. It displays very tight voltage regulation on all voltage lines, at about 0.7% on all of its major voltage outputs, which is very good for such a powerful unit. Voltage filtering is fair, with a maximum ripple of 44 mV on the 12V line under maximum load, which technically is very good and less than half of what Intel’s Design Guide dictates, yet not an excellent result for a unit of this class and higher than what the previous version of the CYBERCORE could accomplish.

As part of our standard testing, we test the primary protections of all PSUs we review (Over Current, Over Voltage, Over Power, and Short Circuit). All of the protections of the XPG CYBERCORE II 1300W PSU engaged normally. Even the OCP and OPP protections, which are frequently set a bit too high on ATX 3.0 compliant units to avoid issues with the high power excursion requirements, kicked in quite quickly, immediately shutting down the unit at less than 115% of the unit’s rated electrical figures.

Conclusion

In terms of quality, the XPG CYBERCORE II 1300W demonstrates commendable build quality, incorporating high-quality Japanese electrolytic and solid-state capacitors alongside high-performance active components. The layout and assembly quality is excellent. Additionally, the inclusion of the NIDEC 120mm fan with its highly reliable dual ball bearing engine ensures its cooling and enhances the unit's long-term reliability. The OEM/ODM for the XPG CYBERCORE II is Channel Well Technologies (CWT), the same manufacturer as the previous generation. The second generation CYBERCORE units are based on a platform similar to the first but it has been significantly upgraded to fully comply with ATX 3.0 requirements.

Electrical performance is perhaps the primary selling point of the XPG CYBERCORE II series. It delivers very tight voltage regulation, whereas the filtering is fair but not high for a unit of this class. Its trump card lies with the energy conversion efficiency, where the unit easily meets the 80Plus Platinum certification requirements regardless of the input voltage. The high efficiency allows it to operate without having to rely on its cooling fan at all while the load is low, having the CYBERCORE II unit operating passively with loads as high as 600 Watts.

The thermal performance of the XPG CYBERCORE II is a bit complex – as the fan is disabled at lower loads, the temperatures will get high. Nevertheless, the temperature never reaches dangerous figures that would immediately impact the longevity of the unit, and the thermal control circuitry will force the fan to start whenever that is necessary regardless of the unit’s loading. Users that may find the operating temperatures uncomfortably high should consider that XPG covers the CYBERCORE II units with a 10-year long warranty, a warranty period that they'd have a tough time meeting if there was any significant thermal stress occurring. Noise levels are practically zero at low to medium loads, thanks to the fan remaining inactive when the load is below 50% of the unit's capacity at room temperature. However, under heavy and prolonged loads, the fan will become loud. Nevertheless, the overall noise performance is outstanding for a unit with that kind of capacity.

Overall, the XPG CYBERCORE II presents a well-built and reliable power supply option, offering good power quality, efficient thermal management, and highly competitive noise levels. Although not yet available in the US/EU markets, the XPG CYBERCORE II 1300W unit is expected to be released here at an MSRP of $319.99. But looking at retailers over in Asia, where the PSU is already available, the price is closer to $280 at current exchange rates; if XPG can do better than their official MSRP and match those prices here, then they'll have a hot commodity on their hands with a reasonably priced option for those seeking a high-end ATX 3.0 PSU. But even with its expected pricing, the CYBERCORE II is priced very competitively for high-end 80Plus Platinum designs, making it poised to become a compelling choice for users demanding high-end performance from their ATX 3.0 power supply units without breaking the bank.

    Wow, a power supply with a Gentle Typhoon in it.

    Reevaluation of your life choices might be a better idea than scrimping coin on a "cheaper" 1300W PSU. If you feel you genuinely need something that can deliver that much power to provide yourself with amusement there's absolutely a problem and it has nothing to do at all with computer components.

    Considering cases and PSUs have the longest retention, a PSU could see several generations of computer evolution where power requirements could go up. Never mind new uses, from personal AI, to VR/AR.

    Nevermind the fact that people are unlikely to demand that much from a single wall outlet on the average household circuit with homes easily 40 to 100 years old and no significant change in wiring. So new uses that add additional devices of that sort of demand are unlikely. Adding various energy costs and associated power-demand increases on the grid from growing numbers of electric vehicles that will spike costs - Yeah I'm going to say that's not well thought out reasoning.

    I read the conclusion as "less expensive" rather than "cheap." The voltage regulation is better than any other unit they tested, and the build quality is "commendable." In the conclusion's final paragraph he states "... presents a well-built and reliable power supply option, offering good power quality, efficient thermal management, and highly competitive noise levels.

    Doesn't really seem to be anything "cheap" about this power supply. It's just a good value for people who would need more power. Gamers wouldn't buy this, someone building a workstation would.

    Concur, which is why I said "cheaper" rather than "cheap" which implies lower price not bottom-of-barrel quality. The point remains though that there's few situations in which 1.3kW would be necessary and all of those situations reach well into "I'm a frantic idiot" territory.

    I just want a boring PSU with this build quality and that fan at half the watts for <$100. It seems most PSU's really cheap out on fans and when they are loaded, the noise output of whatever fan they have is likely drowned out by the rest of the system anyway.
  • hennes - Saturday, July 15, 2023 - link

    I also want the world for free, or for cheap. So maybe < $100 is not that realistic.

    But a well build platinum plus PSU, with no fan noise under normal operation and lasting multiple builds is something I am happy to pay for. No need for 1300W though, even with todays GPU power explosions a 800W is plenty.

    (and just to confirm that, I now have a 850W, nmo fan till 40% load, platinum plus unit with good specs, though at over twice the $100 you mentioned)

    It's hard to find good quality 650-700w PSU's anymore. My last two had poor quality fans and both needed replacing after a few years, and they were expensive PSU's. My other complaint is ATX 3.0 PSU's with the PCIe 5.0 connector all seem to be high output (1000w+ models) even though many cards on the market with a PCIe 5.0 connector are sub-300w cards (like the 4070Ti) with CPU's that are often in the 125w TDP range. A 650w PSU is perfectly matched to that spec.

    It's pretty easy to do a fan swap mod on a PSU.
