Summary

The SAMA P1000 presents itself as a technically solid and exceptionally efficient ATX 3.1 platform for its price class, which is well above what is generally expected in the mid-range in terms of both electrical measurements and acoustic performance. The combination of LLC resonant converter, synchronous rectification, high-quality primary capacitors and a well-tuned PFC stage enables ETA Platinum and 80 Plus Platinum certification, which is reflected not only theoretically but also practically in very high efficiency levels over a wide load range.

The ripple values remain consistently low, the voltage regulation is tightly controlled and the transient response shows that the platform works reliably even under heavily fluctuating GPU loads. In addition, there is a sufficiently dimensioned hold-up time, standard-compliant signal timings and a full range of protective circuits that allow the power supply to be operated safely both in everyday operation and at the limits. A particularly positive aspect is that the noise development remains extremely low over large parts of the load curve and the power supply is almost completely silent in the range of typical gaming or workstation loads.

The internal workmanship is solid for an RSY design and the component selection is pragmatic, but not arbitrary. The FDB fan ensures a quiet and durable operating profile, the modular cables are extensive and geared towards the requirements of modern systems. The scope of delivery with cable bag, Velcro straps and classic accessories corresponds to the standard of this class. All in all, the SAMA P1000 positions itself as a device that shows its strengths not through marketing, but through electrical data and acoustic quality.

The SAMA P1000 is aimed at users who are looking for a powerful and quiet power supply without having to pay the price of the absolute premium devices. This power supply is particularly suitable for gaming systems with powerful GPUs, for productive workstations with high partial loads and for users who value high efficiency in continuous operation. The high electrical stability makes it a solid basis for future GPU generations with extreme load transients, while the quiet operation enables a pleasant system profile in everyday use.

Pros and cons

Price comparison and recommendation for savers

Compared to established premium series such as the Corsair RMx Shift series, the Seasonic Focus PX or the ASUS ROG Loki/Thor family, the SAMA P1000 offers very similar electrical performance, but at a significantly lower price. Premium manufacturers score points with longer warranty periods, more advanced material standards on the secondary side and sometimes even better fine-tuning of the fan curve. Those who prioritize these aspects and are willing to pay the corresponding surcharge will find what they are looking for.

For price-conscious buyers, however, the SAMA P1000 is an extremely attractive alternative. Its efficiency is on a par with top-class Platinum appliances, noise levels are often even lower in the practical range and the electrical measurements are consistently impressive. Although the warranty period is shorter, the risk for long-term operation is limited in view of the measured values and the very low thermal load.

This makes the SAMA P1000 particularly suitable for users who are looking for a technically high-quality, quiet and future-proof power supply, but do not want to pay the extra price for well-known brands. Those who value maximum warranty and absolutely consistent premium components should still opt for the more expensive alternatives. For everyone else, the SAMA P1000 offers excellent value for money and is therefore a clear recommendation for those looking to save money without compromising on performance.

Finally, I would like to thank Aris from Cybenetics and hwbusters.com once again for their usual precise and excellent cooperation. The detailed series of measurements and the complete technical protocol from Cybenetics form the basis for an objective and reproducible evaluation of this power supply unit and make it possible to classify even the finer technical aspects in a transparent and reliable manner. The power supply unit tested here was provided by the manufacturer. However, no influence was exerted on the content, evaluation or focus of this article. Similarly, the test was not paid for or prioritized in the editorial process. The selection of products is based solely on reader demand and current market dynamics.
