In Figure 15, you can see the power supply label containing all the power specs. We don't know when or if this item will be back in stock. The S12II series comes in four different wattages: 330, 380, 430 and 500. [nextpage title=”Transient Filtering Stage”]. Since each output can have a slight variation (e.g., the +5 V output working at +5.10 V), the actual total amount of power being delivered is slightly different than the calculated value. Für Versand nach Österreich, besuchen Sie bitte Seasonic S12II-430 Bronze. It presented efficiency between 83.2% and 86.3%, which is outstanding for an entry-level unit with the 80 Plus Bronze certification. The Seasonic ECO series is very popular for entry level users or for basic computer builds. Basically the same as OP's, but with a beefier CPU: AMD FX 6300. S12III Series.

The 80 PLUS® Bronze certification guarantees greater than 82 %, 85 % and 82 % efficiency at 20 %, 50 % and 100 % operating loads, respectively. 620 W / 520 W / 430 W. POWER DISTRIBUTION. The Seasonic S12II-Series achieves 80 PLUS® Bronze. As you would expect from a PSU cooled by a 120mm fan, the S12II series has a honeycomb mesh at the back of the unit along with a standard sized power switch. I basically want a good quality PSU without breaking the bank, these are really the top dollar I can give out for a PSU. Seasonic Eco Power 300 at 20~90W output, 23 dBA@1m: One meter; Seasonic S12II-380 at up to ~200W output, 21 dBA@1m: One meter S12II Series The S12II Bronze Series is available in the standard ATX Form Factor and in wattages that are most common for a PC system. The intelligent thermal circuit feature is designed to find the optimal balance between the necessity to cool the components and the need to run the power supply in the most silent manner possible. This bridge supports up to 8 A at 100° C. So, in theory, you would be able to pull up to 920 W from a 115 V power grid. They are extremely reliable and generate considerably less operating noise and heat than ball bearing fans. The +3.3 V output uses another MBR30H30CTG Schottky rectifier. The Seasonic S12II-Series achieves 80 PLUS® Bronze standard of providing at least 82 %, 85 % and 82 % power usage efficiency at 20 %, 50 % and 100 % operating loads, respectively. Buy Seasonic S12II 430 Watts PSU only for Rs. Curiously, on the product box and on the manufacturer’s website, this unit is correctly listed as having a single +12 V rail. Assuming 80% efficiency, the bridge would allow this unit to deliver up to 736 W without burning itself out. Seasonic S12II 430 2. Completed Builds Using SeaSonic S12II 430 W 80+ Bronze Certified ATX Power Supply Tento zdroj poskytuje maximální výkon 430W a má pěkné černé provedení.

Interestingly, the S12II-380 is not our first look at this new series of power supplies from Seasonic. All cables are protected with nylon sleeves that come from inside the unit. JavaScript seems to be disabled in your browser. The maximum ripple and noise levels allowed are 120 mV for +12 V and -12 V outputs, and 50 mV for +5 V, +3.3 V and +5VSB outputs. The Seasonic S12II Bronze 430 W uses a regular design in its secondary, with Schottky rectifiers. Inside the unit, all yellow (+12 V) wires are connected to the same point, and the power supply doesn’t implement over current protection (OCP), which is required to create individual +12 V virtual rails. © 2020 Sea Sonic. [nextpage title=”Ripple and Noise Tests”]. For shipping to the United Kingdom visit this page Seasonic S12II-430 Bronze. This gives us a maximum theoretical current of 21 A or 71 W for the +3.3 V output. Let’s find out. Figure 8: Transient filtering stage (part 1), Figure 9: Transient filtering stage (part 2). According to the power supply label, this unit has two +12 V rails. (See Seasonic S12-430: Beyond the Super Tornado and Seasonic S12-330 PSU, new sleeved version). The maximum theoretical current each line can deliver is given by the formula I / (1 – D) where D is the duty cycle used and I is the maximum current supported by the rectifying diode. Are the above protections really available? This should certainly help to keep the three rows of mosfets attached to heat sinks fairly cool. It has a 1050 TI and a Pentium G4600 with 1 SSD and maybe at most 2 HDD/1 optical drive. The electrolytic capacitors that filter the outputs are also Japanese, from Chemi-Con, and labeled at 105° C, as usual. The lubrication of the bearing surface reduces friction and vibration and therefore lowers overall power consumption. These transistors present a maximum 265 mΩ resistance when turned on, a characteristic called RDS(on). Currently this series contains only one model, the 430 Watt unit, which has great features that make it a good choice for people who are looking for an efficient and reliable, good value Seasonic power supply.

The active PFC circuit uses two FDP18N50 MOSFETs, each supporting up to 18 A at 25° C or 10.8 A at 100° C in continuous mode (see the difference temperature makes) or 72 A at 25° C in pulse mode. In my country those 2 are basically the same price. Seasonic is a premium brand manufacturer of consumer and industrial power supplies with extensive experience in creating the highest quality products. My PC doesn't need a lot of power, probably around 250~300W. If you add all the powers listed for each test, you may find a different value than what is posted under “Total” below. Let’s discuss the ripple and noise levels on the next page. The number of connectors is outstanding for a 430 W power supply, allowing you to install a high-end video card that requires two auxiliary power connectors without the need for adapters. Clicking noise from my 2-years-old PSU (Seasonic S12II-430) Not due to fans... Maybe capacitors? All voltages were closer to their nominal values during all tests (3% voltage regulation), making the S12II Bronze 420 W a “flawless” power supply. First we tested this power supply with five different load patterns, trying to pull around 20%, 40%, 60%, 80%, and 100% of its labeled maximum capacity (actual percentage used listed under “% Max Load”), watching the behavior of the reviewed unit under each load. Figure 1: Seasonic S12II Bronze 430 W power supply, Figure 2: Seasonic S12II Bronze 430 W power supply. The +12 V output uses two SBR30A50CT Schottky rectifiers (30 A, 15 A per internal diode at 110° C, 0.55 V maximum voltage drop), giving us a maximum theoretical current of 43 A or 514 W for the +12 V output. In the transient filtering stage, this power supply is flawless, with one X capacitor, four Y capacitors, and one coil more than the minimum required. Figure 13: The +12 V, +5 V, and +3.3 V rectifiers. As a participant in the Amazon Services LLC Associates Program, this site may earn from qualifying purchases. The lower the number the better, meaning that the transistor will waste less power, and the power supply will have a higher efficiency. We consider a power supply as being top-notch if it can produce half or less of the maximum allowed ripple and noise levels. (The power supply’s EPS12V connector was installed on the +12VB input of the load tester.).
