One of the standout features of the XPG Core Reactor 750W PSU is its compatibility with a range of setups. Whether you’re building a gaming powerhouse or a content creation workstation, this PSU has you covered. With an ATX version and adherence to Intel ATX 12V v2.52 standards, the XPG Core Reactor seamlessly integrates into various PC configurations, providing a reliable power source for your components.

Performance and Certification

The 80 Plus Gold certification speaks volumes about the efficiency of the XPG Core Reactor 750W PSU. Delivering a commendable 90% efficiency at 50% load, this PSU ensures that power is utilized optimally, contributing to a stable and reliable system. The Cybenetics LAMBDA/ETA certifications further underscore its performance, placing it at the forefront of efficiency and noise control within its category.

While the XPG Core Reactor 750 delivers commendable performance, it falls short of surpassing the benchmarks set by both the Corsair RM750x and the more contemporary RM750. Although the Core Reactor 750 introduces alternative sleep mode support and achieves super-high efficiency at light loads, those indifferent to these features may find the RM750x a more budget-friendly alternative. In comparison to the RM750, the XPG unit incorporates more reputable components, yet both power supply units (PSUs) promise a minimum of 10 years of longevity, accompanied by robust 10-year warranties.

A notable advantage of the XPG Core Reactor 750 is its absence of in-cable caps, a boon for users as it simplifies cable routing and management processes. The quantity and length of cables, as well as the spacing between peripheral connectors at 145-150mm, meet satisfactory standards. Most electrolytic caps belong to the high-quality Chemi-Con, KY line, ensuring prolonged reliability. However, it’s worth mentioning that a single Chemi-Con KZE, noticeably inferior to KY members, and three Nichicon caps are also present. Additionally, CWT incorporated a substantial number of polymer caps in this platform.

Alongside the Corsair RM750, the XPG Core Reactor 750 stands as the second power supply in this wattage category that adheres to the rigorous requirements outlined by the ATX spec. These specifications demand efficiency higher than 70% with 2% of the max-rated-load (15W) and a Power-Ok delay within 100-150ms, coupled with a Power-on time lower than 150ms. Fulfilling these demands necessitates significant hardware adjustments, contributing to the higher cost of PSUs fully compliant with the newest ATX spec.

The XPG Core Reactor 750 not only boasts high performance but also operates at very low, often silent levels. Loaded with an abundance of modular cables and connectors, including two EPS, six EPS, and twelve SATA, compatibility concerns are virtually nonexistent. Moreover, the PSU effortlessly delivers its maximum power without significant voltage drops. The exceptional build quality is evident as XPG has employed top-tier, expensive components, such as an FDB fan and fully Japanese capacitors, ensuring the PSU easily outlives its extensive warranty period. In summary, the XPG Core Reactor 750 stands as a reliable performer in the PSU realm, striking a balance between performance, features, and longevity, making it a compelling choice for discerning users.

Intelligent Cooling with FDB Fan

The Fluid Dynamic Bearing (FDB) fan in the XPG Core Reactor 750W PSU takes center stage in maintaining an optimal temperature. Operating at 2400 RPM, the 12cm fan strikes a balance between cooling efficiency and noise reduction. The intelligent fan curve ensures near-silent operations, kicking in at a low 3.3v and 660 RPM ± 10%. This thoughtful design choice not only keeps your system cool but also extends the lifespan of both the fan and the power supply unit.

Connectors Galore

When it comes to connectivity, the XPG Core Reactor 750W PSU doesn’t disappoint. The inclusion of an ATX 24 Pin Connector, EPS 8 (4+4) Pin Connectors, PCI-E 6+2 Pin Connectors, Molex 4 Pin Connectors, and SATA Connectors ensures compatibility with a wide array of components. Whether you’re powering a high-end graphics card or multiple storage drives, the XPG Core Reactor has the connectors you need.

Japanese Capacitors for Enhanced Reliability

The XPG Core Reactor takes reliability seriously by incorporating high-quality Japanese capacitors. Renowned for their superior performance and longevity, Japanese capacitors play a pivotal role in maintaining stable DC voltage within ±2%. This not only reduces ripple and noise by up to 35% but also ensures enhanced dependability, crucial for the longevity of your components.

Protections for Peace of Mind

In the unpredictable world of computing, protection features are indispensable. The XPG Core Reactor 750W PSU comes equipped with a comprehensive set of protections, including OCP (Overcurrent Protection), OVP (Overvoltage Protection), UVP (Undervoltage Protection), OPP (Over Power Protection), SCP (Short Circuit Protection), OTP (Over Temperature Protection), NLO (No Load Operation), and SIP (Surge and Inrush Protection). These safeguards ensure that your components are shielded from potential electrical hazards, providing peace of mind during extended gaming sessions or resource-intensive tasks.

For gaming enthusiasts, the XPG Core Reactor 750W PSU is a reliable companion. The robust power delivery and stable voltage output contribute to a smooth gaming experience. Whether you’re engaged in fast-paced FPS games or exploring expansive open-world titles, the XPG Core Reactor ensures that your system remains steadfast, delivering the power your components demand.
