The Seasonic S12II Bronze 430 W is a flawless power supply. As we have mentioned in other articles and reviews, the first place we look when opening a power supply for a hint about its quality, is its filtering stage. Radeon R9 280 + a standard ATX mobo, 2 sticks of RAM, and a 7200rpm HDD Let’s discuss the ripple and noise levels on the next page. The objective of this test is to see if the power supply has its protection circuits working properly. Make sure this fits by entering your model number. Basically the same as OP's, but with a beefier CPU: AMD FX 6300. Do you think a 430W Seasonic S12II (about 7 years old, but still working just fine in another PC) would be enough to power this system? We conducted several tests with this power supply, as described in the article, “Hardware Secrets Power Supply Test Methodology.”. 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. This power supply uses one GBU806 rectifying bridge, which is attached to an individual heatsink. Figure 12: Active PFC/PWM combo controller. On the next page, we will have a more detailed discussion about the components used in the Seasonic S12II Bronze 430 W. On this page we will take an in-depth look at the primary stage of the Seasonic S12II Bronze 430 W. For a better understanding, please read our “Anatomy of Switching Power Supplies” tutorial. https://www.newegg.com/seasonic-s12-ii-ss-430gb-430w/p/N82E16817151033 Please read our “Anatomy of Switching Power Supplies” tutorial to understand how a power supply works and to compare this power supply to others. The lubrication of the bearing surface reduces friction and vibration and therefore lowers overall power consumption. cTUVus, TUV, Gost-R, UkrTEST, CB , BSMI, Semko, CCC, CE, FCC, C-tick, 1 x 100 mm - end connector of the peripheral cable, Dimensions: 140 mm (L) x 150 mm (W) x 86 mm (H). The electrolytic capacitors that filter the outputs are also Japanese, from Chemi-Con, and labeled at 105° C, as usual. You won’t regret it.

The herringbone shape of the groves helps to efficiently channel the lubricant and avert leakage. During this test, both inputs were connected to the power supply’s single +12 V rail. Your email address will not be published. Privacy Policy. The S12III Bronze Series is available in the standard ATX Form Factor and in wattages that are most common for a PC system. Only Genuine Products. Currently unavailable. Published: 29th November 2007 | Source: Seasonic | Price: £45.00 | Author: James Napier. 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. If you add all the powers listed for each test, you may find a different value than what is posted under “Total” below. As the S12II series is effectively cooled "bottom-up" by a 120mm fan, Seasonic have also taken the liberty of designing the heatsinks in a way that will create turbulence in the airflow thus providing more effective cooling. (See Seasonic S12-430: Beyond the Super Tornado and Seasonic S12-330 PSU, new sleeved version). The Seasonic ECO series is very popular for entry level users or for basic computer builds. The Seasonic S12III-Series achieves 80 PLUS® Bronze standard of providing at least 82 %, 85 % and 82 % power usage efficiency at … As an exercise, we can assume a duty cycle of 30 percent. 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. They are extremely reliable and generate considerably less operating noise and heat than ball bearing fans. 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 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 is 5.5” (140 mm) deep, using a 120 mm ball-bearing fan on its bottom (ADDA AD1212MB-A70GL). The following information has been taken directly from Seasonic's recent press release and Nanopoint's (Seasonic's UK Distributor) website: The S12II series is made up of 330, 380, 430 & 500 watts units. The specifications for these transistors were already discussed above. In summary, you can buy this power supply with your eyes closed. 620 W / 520 W / 430 W. POWER DISTRIBUTION. The Seasonic S12II-Series achieves 80 PLUS® Bronze. Voltages at the power supply outputs must be as “clean” as possible, with no noise or oscillation (also known as “ripple”).

The Seasonic S12II Bronze 430 W is 5.5” (140 mm) deep, using a 120 mm ball-bearing fan on its bottom (ADDA AD1212MB-A70GL). 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. And, to top it off, the price is more than right for all the features this power supply brings. The S12II 430 Bronze Series is available in the standard ATX Form Factor and in wattages that are most common for a PC system. The S12II series comes in four different wattages: 330, 380, 430 and 500. This should certainly help to keep the three rows of mosfets attached to heat sinks fairly cool.
