Seasonic X-1250 (SS-1250XM2) 1250W Review
Cada computadora siempre tiene un propósito diferente, por lo tanto tendrá distintas formas y características, lo que resulta en un consumo energético que varía considerablemente. Aclarado eso podemos concluir que no existe una fuente de poder universal, sino que hay que escoger una que tenga la capacidad de alimentar el equipo de manera satisfactoria. Un sistema promedio puede sobrevivir con una unidad de baja capacidad sin duda. Pero cuando se trata de equipos de alto rendimiento, que disponen de varios procesadores o tarjetas gráficas, es otra historia. En casos extremos como estos, utilizar una unidad de gran capacidad tiene mucho sentido y resulta en una sabia elección.En el presente la Seasonic X-1250 (SS-1250XM2) es la fuente de poder con mayor capacidad que existe en el portafolio de la marca. La SS-1250XM2 es capaz de entregar la impresionante capacidad de 1250W además de contar con una certificación 80PLUS Gold, pisándole los talones a las unidades con certificación 80PLUS Platinum. La unidad actualmente forma parte de la Serie X de Seasonic, que ha sido renovada con una plataforma cuidadosamente actualizada. Estas nuevas unidades se diferencian de los anteriores por la leyenda «XM2» presente en sus números de modelo.

Una Mirada Más Cercana
La portada de la caja luce un fondo oscuro con acentos en dorado. Una imagen parcial de la Seasonic X-1250 se encuentra en la esquina inferior derecha junto con el logotipo de la certificación 80PLUS Gold. Logotipos propios de la marca, la Serie X y capacidad del modelo están presentes también.
Desplazándonos a la parte posterior de la caja, se nos presenta una imagen del interior de la fuente de poder. Seasonic ha se ha esforzado por explicarnos algunas de las características más importantes de la misma.
Descubrimos varios accesorios que nos facilitaran la instalación de la unidad, así como la administración de los cables. Tenemos varios cinchos, organizadores de velcro y tornillos. También hay un manual de usuario y una calcomanía a modo de decoración.
Como es de costumbre en los modelos de gama alta, un estuche atractivo alberga todos los cables modulares que se utilizan con la fuente de poder. Los cables tienen un diseño plano para facilitar su manejo dentro del gabinete. Solo el cable ATX tiene un diseño redondo por su grosor.
Una base gruesa fabricada con hule espuma tiene la importante tarea de proteger la Seasonic X-1250 contra cualquier percance que pueda ocurrir durante su manejo.
Aparte de la base de hule espuma, la Seasonic X-1250 esta guardada en una bolsa negra de terciopelo que tiene grabado el logotipo de Seasonic en dorado. Esta pequeña bolsa asegura que la fuente de poder llegue al usuario final libre de rayones y polvo.
Las unidades con capacidades mayores a 1000W suelen venir en tamaños más grandes por los componentes internos adicionales que conforman su fabricación. Por lo mismo la Seasonic X-1250 mide 190mm de largo, 150mm de ancho y 86mm de alto. El cuerpo tiene un acabado negro mate con acentos dorados. La ventilación de la unidad es apoyada por un ventilador de 120mm en la parte inferior.
En uno de los lados, se puede apreciar el logotipo de Seasonic y otro de la Serie X en tonos dorados.
En el lado opuesto, encontramos una etiqueta grande que nos especifica los detalles técnicos de la Seasonic X-1250W.
La Seasonic X-1250W es una unidad completamente modular por lo tanto tiene un panel donde se ubican todos los conectores modulares para conectar los cables. Estos conectores están ordenados en filas. Cada uno tiene su señalamiento respectivo para que el usuario sepa cual cable va en cual conector. Por último, vemos un interruptor para elegir el modo de control de ventilador.
A través del interruptor, el usuario puede elegir entre el modo S2FC o el modo S3FC. El modo S2FC mantiene el ventilador en operación todo el tiempo mientras el modo S3FC mantiene el ventilador apagado hasta que la carga sobrepase cierto porcentaje de la capacidad de la fuente de poder. A esta nueva característica, Seasonic le ha denominado “Hysteresis” que consiste en un circuito integrado que controla con qué frecuencia se prende y se apaga el ventilador. Asumiendo que la unidad se encuentre en un entorno con una temperatura ambiental de 25°C, el ventilador se prende cuando la carga sobrepasa el 30% de la capacidad de la unidad y se apaga cuando la carga disminuye abajo del 20%. De esta manera, el ventilador se prende y se apaga con menor frecuencia que da resultado una reducción de la pérdida de potencia en el modo sin ventilador o modo silencioso.
Seasonic favorece el uso del diseño en forma de panal en su panel trasero de sus unidades porque brinda mayor eficiencia de ventilación y a la vez menor nivel de ruido. El interruptor de encendido y apagado tiene un tamaño grande para facilitar su uso.
Una vez abierta la unidad, podemos apreciar el modelo del ventilador de 120mm. En esta fuente de poder en particular, Seasonic implementa un ventilador Sanyo Denki San Ace que es muy conocido por su alta calidad, confiabilidad y flujo de aire. El ventilador con modelo 9S1212h503 utiliza rodamientos de bolas y consta de siete aspas para mover una cantidad grande de aire para enfriar los componentes internos de la unidad.
Seasonic ha elegido utilizar su plataforma insignia XP3 para la X-1250W. Y como siempre podemos observar componentes de alta calidad en su manufactura. La disposición de los componentes esta ordenada y el trabajo de soldadura es impecable.
La Seasonic X-1250 utiliza nada menos que tres capacitores japoneses primarios de alta confiabilidad. Al acercarnos a ellos, descubrimos que provienen de la marca Hitachi y están certificados a 390uF, 420V y 105C.
La parte secundaria está dotada de capacitores electrolitos y capacitores polímeros que son de Nippon Chemi-Con.
Los disipadores de calor están dispersos a través de la unidad. Se encargan de enfriar los diferentes áreas y componentes como los FETS, rectificadores, controladores.

We remind that we have a BEST PRICE GUARANTEE. This means that you can buy gypsum boards (GSP and GSPV) at the best price in Moscow!
Gypsum Particle Board (GSP) is an innovative, environmentally friendly building material for interior finishing of floor, wall, partition and ceiling structures. Composition : gypsum 83%, shavings 15%, moisture 2%. The high-tech and fireproof (G1, T1, V1, RP1, D1) material is significantly superior in quality and physical and mechanical characteristics to the well-known Gypsum cardboard (GKL), Gypsum fiber sheet (GVL) and other similar plate (sheet) materials used for interior decoration.
GSP slab is widely used in premises: social facilities, medical institutions, schools, kindergartens, sanatoriums, etc., as well as in residential, public, industrial, administrative buildings as:
— lining of internal wall surfaces, ceilings and partitions
— prefabricated floor base screeds for various finishing coatings
— fire-retardant lining of wooden and steel structures
Gypsum chipboard solves a number of problems in low-rise housing construction:
— strip foundation (fixed formwork)
— subfloor (two layers along the logs with offset seams)
— finishing for finishing the internal thermal contour of wall structures, ceilings, partitions
Exterior wall | Partition |
Interfloor ceiling |

DETAILS
Relatively recently, a new building material appeared on the Russian market — gypsum chipboards (GSP). It is a high-quality, environmentally friendly, durable and fire-resistant material, which is widely used in construction, from private residences to administrative public buildings. GSP slab is a kind of analogue to drywall and gypsum fiber, but a more innovative and high-quality building material.
The plate manufacturing technology is carried out by semi-dry method of mixing wet wood shavings and gypsum binder, this mass is placed on steel sheets, after which it is pressed and dried without heating to high temperatures. This manufacturing technology contributes to the strength of the plates, they are not subject to deformation, because. their humidity and ambient humidity is the same.
Gypsum boards were first developed in Germany and presented in 1982 at an international conference. Over time, this material became very popular throughout Europe.
In Russia, gypsum board has also gained immense popularity due to its excellent performance, such as:
• excellent sound insulation (gypsum itself is an excellent sound insulator)
the main connecting link in the composition of the boards is gypsum, which protects the wood shavings in the board from fire
• High strength
• Eco-friendly — no glue or resins. GSP stove is absolutely safe for human health!
It is very effective to use gypsum boards in damp rooms, because they have the ability to absorb it at high humidity and vice versa, when the air is dry, to release moisture, which allows you to create a comfortable microclimate. With prolonged exposure to moisture, the moisture-resistant plate does not change its properties and characteristics.
GSP slab structures are well suited for further decorative finishing, they can be wallpapered, painted, tiled and ceramic tiled. In addition, the surface of the plates makes it possible to use such finishing materials that require a perfectly smooth surface, for example, film coatings, etc.

Sergei Drobyshevsky Yesterday I finally tested the tent in winter conditions, spent the night in it in the mountains, in the forest area. В Viorel September 9, 2022 09:35 Competitor MSR The first time I used a Normal tent (rented) in Kamchatka, I was satisfied and therefore decided to buy my own. The choice fell on Elbrus 2 SI PU. Lightweight, spacious enough, good performance, easy to install, etc. I have been using it for more than a year, I tested it in different regions and at different times of the year. С Sergey Drobyshevsky May 30, 2022 23:22 Normal Elbrus 2 tent Great tent! A worthy competitor to the American MSR Nubba Hubba NX and HP. Not inferior to the «Americans» in comfort, but in terms of reliability and strength of materials, durability — superior. Excellent awning, inner tent, good durable mesh part, bottom. An excellent balance has been found between the strength of the tent and its weight (the maximum weight of the Normal Elbrus 2 tent is 2.5 kg ..). I have already learned from bitter experience that for the sake of low weight (ultralight, crazylight) one cannot sacrifice the strength and durability of the patty (make a thinner awning, thinner retina and bottom, less dense weave of threads in the fabrics from which the tent is sewn). V Vera October 17, 2021 15:48 Good tent Good afternoon! We go hiking all the time, but mostly in the summer. Our focus is hiking with a base camp, so there we live together in a 6-seater tent-palace with a hall, where we hold tea ceremonies and so on. And this summer I had to go for several days from the camp alone with the team and drag all my and other things on the back. Therefore, I began to look for and buy a light small tent. I took this Elbrus 2sipu. Cool size — I fit with a big backpack with a bang. She put shoes and a mug into the vestibule from the top awning. Inside, I put a watch on the upper grid, for example. Also convenient. Not very many times I personally assembled and set up tents, but I figured it out quite soon. Norm, convenient. I also like the top olive color, it mimics a forest)) and inside it is a positive yellow. V Vlad August 25, 2021 17:44 The first check of the tent Lived in a tent for 7 nights, no complaints, the material is light and durable One of the features is a very thin floor (maybe it is very durable, I did not check it, but it looks flimsy), you need to carefully choose and prepare a place for setting up a tent, or carry a bed under it with you In general: satisfied with the purchase, it seems that it is worth the money, it remains to be checked by time See all 8 reviews of Elbrus 2 Si / PU they require proper handling and storage.
Awning and inner tent The main thing that tents are afraid of is storage in a damp state and, as a result, the formation of mold during storage. Therefore, if the weather permits, dry the tent well before assembling and packing. If this is not possible, be sure to dry the tent at home as soon as you return. Frame When assembling the arches, pay attention to the joints of the tubes — there should be no gaps between the elements. Avoid getting dirt and sand on the connecting elements of the frame. Pegs Tent pegs must be attached only to the reinforced loops provided for this purpose, and not to loops for folding skirts, etc. The latter are not designed for wind loads and can be torn out with a strong gust of wind. When packing, sharp pegs should be stored in a tight bag so that they do not damage the tent during transportation. In a word, if you take care of your tent, it will reliably protect you from cold and dampness.
The outer canopy of the Normal Elbrus 2 Si/PU tent comes in two versions: for those who like bright colors — yellow, and for lovers of tranquility and asceticism — olive. The convenient case has a nice design, it is comfortable to carry in your hands and fits easily into a backpack. The cover has a drawstring on one side, a zipper with handles on top. In addition to the awning, frame, inner tent, the kit includes braces, pegs — 8 pieces of a classic shape, all this is in convenient cases. There are also repair bushings and clamps. The tent is a two-layer structure with a prefabricated frame and an independent inner tent. Quick assembly of the frame is achieved by connecting all the elements together with rubber cords and aluminum hubs. The tent is designed for three seasons: spring, summer, autumn. This tent is double, with two identical vestibules in front and behind, the width of the vestibule is 80 cm. The internal volume of the tent is 128 cm (width) by 210 cm (length). Under the awning at the entrance to the inner tent there is an anti-mosquito net equipped with a zipper with two locks. The zipper is two-way, works in different directions. If it became cool at night, then the grid can be closed completely or partially. The grid forms through ventilation. On the other side is exactly the same entrance. Let’s take a closer look at the inside of the tent. Here you can see a vent made up of mesh. On the opposite side is exactly the same. Below the ventilation are long pockets, which are also duplicated on both sides. These pockets are designed to hold small items such as documents, phones, etc. On top of the tent there is also a pocket in the form of a hanging shelf, if desired, it can be easily removed. Let’s talk about decoding and designations Elbrus Tent 2 Si/PU. When removing the awning, first loosen the braces at the bottom along the perimeter of the tent. Next, remove the mount on the transverse arc. There is also a guy line in this place, it is made for convenience — we just pull it towards ourselves and release the arc. To attach the frame, a small metal element is sewn on a sling at each corner of the inner tent. On the other side of the element, a sling is attached to fix the “inside” to the ground with the help of pegs. In conclusion Tourist tent Elbrus 2 Si/PU is designed for hiking, water and other types of trips where weight plays an important role. |
