SAMA P1200 Platinum Power Supply vs Lian Li SP850 V2 Gold 850 Watt SFX Form Factor Power Supply

Overview

When comparing the SAMA P1200 Platinum Power Supply and the Lian Li SP850 V2 Gold 850 Watt SFX Form Factor Power Supply, both units offer fully modular designs, but they cater to different power needs and efficiency ratings. The SAMA P1200 is priced at C$164.99 and provides a substantial 1200W output, while the Lian Li SP850 V2, priced at C$194.23, offers a lower 850W output. This article will delve into their specifications, efficiency, cooling solutions, and more to help you make an informed choice.

Power Output

The SAMA P1200 boasts a significant power output of 1200W, making it an excellent choice for high-performance systems, especially those with power-hungry components like next-gen GPUs. In contrast, the Lian Li SP850 V2 provides 850W, which is suitable for mid-range builds but may not suffice for heavy-duty gaming or workstation setups. This difference in wattage can be crucial depending on your system's demands, especially if you plan to upgrade to more powerful hardware in the future.

Efficiency Rating

The SAMA P1200 is certified with 80 PLUS Platinum and Cybenetics Platinum ratings, delivering over 92% efficiency at typical loads. This high efficiency not only reduces energy waste but also minimizes heat output, contributing to a cooler operating environment. On the other hand, the Lian Li SP850 V2 holds an ATX 3.1 certification and, while efficient, does not match the SAMA's Platinum rating. The SAMA P1200's superior efficiency can lead to lower electricity bills and a more stable performance under heavy loads, making it a more future-ready option.

Cooling Solutions

Cooling is a key consideration for power supplies, and both the SAMA P1200 and Lian Li SP850 V2 incorporate advanced fan technologies. The SAMA P1200 features a 140mm fluid dynamic bearing fan that operates in a near-silent mode below 60% load or 55 degrees Celsius, achieving a LAMBDA A+ noise rating. In comparison, the Lian Li SP850 V2 uses a 92mm fluid dynamic bearing fan designed for low noise and efficient thermal management. While both units are built for quiet operation, the larger fan in the SAMA P1200 may offer better cooling capabilities, particularly during intense gaming or heavy usage.

Build Quality

Both power supplies utilize high-quality components, ensuring long-lasting performance. The SAMA P1200 is built with 100% Japanese 105°C capacitors, which contribute to its reliability and stability under load. The Lian Li SP850 V2 also employs high-quality Japanese electrolytic capacitors for stable power delivery. However, the SAMA's emphasis on premium materials and a robust design, coupled with its ten-year warranty, underscores a commitment to longevity and performance that may appeal to enthusiasts who prioritize durability.

Compatibility

In terms of compatibility, the SAMA P1200 is ATX 3.1 compliant and supports PCIe 5.1, making it compatible with the latest hardware and capable of handling extreme power excursions of up to 235% of its rated load. It also features dual 12V-2x6 connectors, delivering up to 600W directly to your graphics card without the need for adapters. Conversely, the Lian Li SP850 V2 is also ATX 3.1 certified and designed to support PCIe Gen 5.0 but offers a single 12V-2x6 connector. This makes the SAMA P1200 a more versatile choice for users looking to integrate the latest technology into their builds.

Size and Form Factor

The size and form factor of a power supply can significantly impact its installation. The Lian Li SP850 V2 is designed to fit within the official ≤63.5mm SFX size specification, which allows it to be used in compact builds. The SAMA P1200, while a bit larger, also features a compact 150mm depth, making it suitable for tight cases. If your build prioritizes space efficiency, the Lian Li’s smaller form factor might be more advantageous. However, if you require higher wattage, the SAMA remains a compelling option despite its slightly larger size.

Warranty and Support

When considering warranty and support, the SAMA P1200 offers a notable ten-year warranty, which reflects the manufacturer’s confidence in their product's longevity and reliability. The Lian Li SP850 V2 also comes with a ten-year hardware protection plan, providing peace of mind for users. Both models offer substantial warranty periods, but the SAMA’s robust build quality may give it an edge in terms of long-term reliability.

Which should you buy?

Choosing between the SAMA P1200 Platinum Power Supply and the Lian Li SP850 V2 Gold 850 Watt SFX Form Factor Power Supply largely depends on your specific needs and system requirements. If you are building a high-performance machine that requires more power and efficiency, the SAMA P1200 at C$164.99 is a superior choice, offering 1200W output, Platinum efficiency, and excellent cooling features. However, if you are focused on a compact build with moderate power needs, the Lian Li SP850 V2, priced at C$194.23, offers a robust option with a smaller form factor and still solid performance. Ultimately, weigh your power requirements, system compatibility, and budget to make the best decision for your setup.
