A bag specifically for storing the modular cables is also included. In addition to the standard AC power cord and four mounting screws, the CyberCore II PSU from XPG comes with a number of cable ties and a sheet of stickers for decoration purposes. The ATX, EPS, PCI Express, and 12VHPWR cables are all black and covered in nylon sleeving. In contrast, the power cables for Molex and SATA are just black wires that resemble ribbons.

Finally, the wires are rather lengthy, particularly the ATX and EPS ones. As I expressed my concern in my previous review of XPG Core Reactor II 1200W PSU for using hard-sleeved cables, the same is the case with CyberCore II 1000W! XPG should really stop using such cables that are extremely hard to route in tight spaces.

WARNING: The sleeved cables may pose challenges during cable routing and management, particularly in compact or crowded PC cases.


From the outside, the XPG CyberCore II is subtle due to its understated matte all-black appearance and lack of flashy additions. Its 160 mm chassis length is somewhat longer than the standard ATX design rule of thumb, but that’s normal for a standard high-output PC PSU and surprisingly small for a unit with that much juice.

On the top side of the chassis, you can see a big label that XPG applied, that includes the unit’s electrical characteristics and certifications. On each side of the chassis, located between two punched triangle shapes, you can find simple decorative stickers with the manufacturer and series logos.

The CyberCore II PSU back side is simple, with just the standard on/off button and the standard IEC C14 power connection. There is an empty space that can accommodate a sticker or something, but thus, nothing has been put in.

Even in their most compact form factor, all configurations have managed to attain ETA PLATINUM grade while maintaining a LAMBDA A- rating for noise. This is their official statement that they would provide their PC users with the highest possible performance since the highest quality standards set by Cybenetics have been approved for the XPG CyberCore II series.

PRO TIP: Regularly clean the PSU and surrounding components to prevent dust buildup, which can impede airflow and increase operating temperatures.

Cable Connections

In an effort to accommodate as many connections as possible, the unit’s front side has a remarkable number of modular cable connectors. Where EPS and PCI Express connectors take up over half of the available space. Since there wasn’t much space for a legend, XPG simply painted several headers on the chassis and organized the connections together using simple lines.

The 24-pin ATX connection and all of the DC power cables are detachable thanks to the XPG CyberCore II 1000W PSU’s completely modular design. There are twelve SATA connections, eight 4-pin Molex connectors, two EPS connectors over dedicated cables, six PCIe 6+2 pin with the same number of cables, and one 12VHPWR set at 600W.

There is a great deal of 4-pin Molex and SATA connections. At 150 mm, the spacing between all of the peripheral connections is adequate. Since it comes with a 12VHPWR (12+4 pin) connection, it is compatible with the most recent high-end graphics cards.

Typically, high-output PSUs have fans measuring approximately 135 mm in size. However, the fan in the XPG CyberCore II 1000W II 1000W PSU is rather smaller. But the XPG CyberCore II 1000W’s 120 mm fan is a top-tier XPG VENTO PRO 120 PWM Fan from Nidec, a world-renowned manufacturer known for its outstanding cooling efficiency, quiet operation, and 60,000-hour lifespan at 60℃ thanks to its Dual Bearing and proprietary design.

It attempts to control airflow by partly covering it with a plastic shield and reaching an extremely high maximum speed of 2150 RPM. Because of the plastic shield and ball-bearing engine, the PSU can make more noise when it’s loaded. However, considering XPG’s 10-year warranty, it’s clear that long-term dependability was a priority.

Its intelligently engineered fan curve extends the life expectancy and minimizes the noise of the XPG CyberCore II series. The PSU has an admirably low noise level for its capacity, earning a Cybenetics A-(25-30 dB[A]) noise certification, all thanks to the top-of-the-line fan from Nidec.

Teardown & Component Analysis

XPG CyberCore II 1000W is based on an updated platform from CWT that was previously used in older CyberCore PSUs from XPG. CWT has tuned up its existing CTT platform to meet Intel’s ATX3.0 specifications. Its major improvements are due to CTT’s Semi-digital design, which not only significantly improves voltage regulation but also has much greater efficiency figures. I still wish to see a fully digital PSU, and I strongly believe XPG is among the very few manufacturers that can achieve this engineering marvel in the near future. So I am hoping for the best.

We first meet with Interleaved PFC on the primary side instead of conventional Active PFC. A dedicated MCU from Texas Instrument controls the workings of Interleaved PFC, making it much more efficient during different load combinations. Full-Bridge & LLC converter makes up for conversion losses when high voltage DC gets chopped off into lower 12V DC via Synchronous Rectification.

On the secondary side, the 12V rail is controlled by a second MCU from Texas Instrument. Though this could also be achieved by using a conventional Analog Controller, the Digital Controller will always remain superior due to its exceptionally fast response time and when I already have very demanding ATX3.0 specifications that allow modern PSUs to maintain their voltage regulation even when the PSU goes up to 200% of their rated power during power excursions, such Digital Controller designs have now become quite essential.

12V rail transformer uses direct solder connections on a vertical PCB that houses 12V rail MOSFETs. A few OEMs solder these MOSFETS on the opposite side of the PCB which causes huge stress on the MOSFETS due to not being able to receive proper airflow, so this approach is always good to see in OEM design.

Furthermore, a dedicated DC-DC daughter board is responsible for converting minor 5V & 3.3V rails. I don’t see hefty heatsinks in this platform because it doesn’t really need them, thanks to its Platinum efficiency and adequate spacing on the PCB coupled with Nidec’s superior quality fan that makes this PSU cool and quiet.

XPG CyberCore II 1000W uses all Japanese high-quality 105℃ capacitors. The electrolytic capacitors are provided by Rubycon and Nippon Chemi-Con, while the polymer capacitors are sourced from FPCAP and United Chemi-Con.

How Did We Test?

At Tech4Gamers, we do things differently when it comes to testing PSUs. Because we are not providing any specific certifications to the PSUs, instead we actually put PSUs through real-life challenges. We’ve created our own special PSU tester based on DC Loading MOSFET modules, that’s designed to measure how well a PSU performs under different stress conditions accurately.

Our main focus is on figuring out how well PSUs handle the demands of gaming computers. We look at things like how stable the voltage is, how efficient the PSU is, how hot it gets, and how much noise it generates in both electrical (voltage ripple) and audible terms. This way, we can give people all the information they need to pick the right PSU for their gaming setup, whether they’re building a top-of-the-line rig or trying to stick to a budget build.

PSU Load Testing

12V & Minor Voltage Rails Regulation

I tested the PSU by gradually loading up the 12V rail at different percentages: 20%, 50%, 80%, 90%, and finally, 100%. Meanwhile, I keep the minor rails, which are the 5V and 3.3V, constant at a combined power of 25W. This is because the minor rails mainly power less-demanding components like HDDs, SSDs, RAM, and other minor parts on the motherboard, so they don’t need as much stress testing. The 12V rail, on the other hand, powers the most power-hungry components like the CPU and GPU, so it undergoes more rigorous testing.

Load in %            12V        5V          3.3V
20%       12.05V 5.05V 3.29V
50%       12.02V 5.04V 3.29V
70%       12.00V 5.04V 3.29V
90%       11.97V 5.04V 3.28V
100%    11.97V 5.04V 3.28V

The voltage regulation is outstanding, largely thanks to the implementation of digital controllers. I anticipate that more manufacturers will adopt this design for their PSUs, particularly considering the heavy load on the 12V rail imposed by ATX3.0 specifications and the significant power demands of modern systems.

An essential powerhouse for today’s demanding PC!

PSU Efficiency

Efficiency is really important when it comes to PSUs because it affects how much energy gets wasted as heat. The more efficient a PSU is, the less energy it wastes, which means lower electricity bills and better longevity for your PSU’s internal parts, especially the capacitors. So, paying attention to efficiency can save you money in the long run and help your PSU last longer.

Load in %            Power Factor    Efficiency
20%       0.952 92%
50%       0.965 94%
70%       0.971 94%
90%       0.985 94%
100%    0.988 93%

The use of interleaved PFC and digital controllers has greatly boosted the efficiency of the XPG CyberCore II 1000W, making it effortless for it to reach Platinum efficiency.

Voltage Ripple Performance

This test will show how good a PSU is when it comes to handling minor or extreme overclocking. A PSU with better voltage ripple performance means it’s made with high-quality components. PSUs produce direct current (DC) output voltages. Ideally, this DC signal should have zero frequency, but because it’s generated from alternating current (AC) signals, there’s always some AC voltage present, known as voltage ripple. High voltage ripple can shorten the lifespan of electrolytic capacitors and cause issues like system crashes (BSODs) when overclocking.

Load in % Voltage Ripple
20% 8.8mV
50% 9.6mV
70% 13.6mV
90% 14.4mV
100% 16mV

The ripple performance is quite good, ensuring stable performance even during extreme overclocking.


With the fan switched off at fewer loads, the XPG CyberCore II 1000W’s thermal performance becomes complicated, leading to somewhat high temperatures. But the temperature never gets too high, which would shorten the lifespan of the PSU, and the fan will turn on whenever the thermal control circuit says it has to, no matter how much stress it’s under.

At low to medium loads, the fan is inactive as the load is less than 50% of the unit’s capacity at room temperature hence, there is almost no noise. But, the fan can generate a bit of noise when the load is heavy and continues for a long time. Regardless, it has exceptional noise performance overall.

12VHPWR Cable Performance On Max Load

12VHPWR cable sustained the load of 600W without breaking a sweat at the voltage level of 11.88V.

Final Verdict

Thanks to its use of premium active components and electrolytic and solid-state Japanese capacitors, the XPG CyberCore II 1000W has an admirably sturdy construction. The design and quality of the assembly are top-notch. Along with the exceptionally reliable twin-ball-bearing engine, the NIDEC 120mm fan is a great addition that keeps the PSU cool and increases its durability. Of course, the MSRP is a bit high, but there isn’t a cheap semi-digital power supply on the market.

The XPG CyberCore II series’ electrical performance is perhaps its main selling feature. The voltage regulation it provides is quite tight. The PSU energy conversion efficiency is outstanding; it effortlessly meets the standards for 80Plus Platinum certification irrespective of the input voltage. The CyberCore II unit can run passively with loads up to 600 Watts because of its great efficiency, which means it doesn’t need a cooling fan at all when the load is low.
