Definition

The ripple voltage of the outputs shall be measured at the pins of the output connector when terminated in the load impedance specified in Figure 1. Ripple and noise are measured at the connectors with a 0.1uF ceramic capacitor and a 10uF electrolytic capacitor to simulate system loading. Ripple shall be measured under any condition of line voltage, output load, line frequency, or operation temperature.

FAQs Silverstone Strider Plus Series ST70F 700W Power Supply

How dependable are SilverStone power supplies?

Since SilverStone like high-power-density PSUs, it’s not surprising that they went with a small platform. The CSZ platform from CWT may be little, but it offers great performance and is extremely dependable. Due to this, several well-known companies make use of it.

How does SilverStone Strider perform?

In summary, the Silverstone Strider Platinum 650W power supply performs well and lives up to its claims. It oscillates at a low voltage and has a high efficiency. Additionally, even when the power supply is strained, the 120mm fan in use is silent.

Is SilverStone a quick course?

Since holding the first Formula 1 World Championship round on May 13, 1950, the Grand Prix Track layout has undergone numerous alterations to create a difficult and quick circuit.

Who makes SilverStone power supply products?

Most of their products are produced by Sirtec, FSP, or Enhance. Silverstone is a respectable brand all around.

How good is SilverStone Decathlon?

Although the price is a little more than that of comparable PSUs made by lesser-known firms, Silverstone offers value for the money. From top to bottom, the Decathlon DA750 is a PSU of the highest caliber.

Is Deepcool’s PSU quality?

The Deepcool PX1200G is one of my top selections for ATX v3.0 & PCIe 5.0 power supplies. With many pertinent products in its portfolio, Deepcool has a strong position in the PSU market in addition to a lengthy experience in cooling devices and chassis.

Why is Silverstone its name?

‘Farm/settlement of Saewulf/Sigewulf’ is likely what the village’s name denotes. The British Grand Prix is currently held at the Silverstone Circuit, which is close by and divides the counties of Northamptonshire and Buckinghamshire.

What is the purpose of Silverstone?

The Northamptonshire villages of Towcester, Silverstone, and Whittlebury are close to the English motor racing circuit known as Silverstone Circuit. It serves as the host of the British Grand Prix, which was first held there in 1948.

Why is Silverstone such a challenge?

Silverstone presents more than only incredibly quick and energetic corners like the Maggotts and Becketts complex. The harshest compound is needed for the British circuit, one of the toughest on the calendar. Drivers must concentrate on the tires’ thermal control.

What makes SFX and SFX L different from one another?

An SFX-L PSU, the bigger version of the SFX, typically measures 125 x 125 x 63.5mm. SFX-L power supplies are made to be compact and can yet fit in cases as small as a micro-ATX. In a manner similar to SFX, SFX-L PSUs are frequently fully or partially modular, allowing you to just use the cables you require.
