5 power supplies with a capacity of about a kilowatt

SilverStone Decathlon DA850R is a computer power supply that fully complies with the two new standards ATX 3.0 and PCIe Gen5. This means having a single 16-pin video card power connector instead of two separate 8-pin ones. For PCI-Express 4.0 video cards it is optional, while with the release of fifth-generation models it will become mandatory.

The power supply cables are completely modular, that is, every single one is removable, even those that power the processor and motherboard. Accordingly, you can leave only those necessary for your specific PC configuration in order to reduce the chaos of wires. The kit includes both a newfangled 16-pin video card cable and a classic 6+2-pin cable.

The power supply, although made in the full-size ATX format, is only 14 centimeters long, which makes it a suitable choice for building a Mini-ITX PC. The SilverStone company also specializes in compact computer cases, so it traditionally indicates in the power supply specifications the power in terms of the occupied volume - 471 watts per liter.

PCCooler YN850 is a power supply of an even more advanced ATX 3.1 standard. Compared to its predecessor, it received an improved 16-pin video card connector with more reliable contact. This eliminates the risk of damage to both the connector itself and the video card as a whole. Without exception, all electrolytic capacitors used in the power supply are manufactured in Japan.

All possible electrical protections are implemented: from short circuits, power surges, overload and overheating. The ventilation holes are made not in the form of the usual hexagonal honeycombs, but in the form of triangles, which looks fresh against the background of competitors of the same type. The Fluid Dynamic Bearing fan with an increased diameter of 13.5 cm does not rotate at all at low load on the power supply.

Semi-passive ECO cooling not only extends the life of an already durable turntable (up to 100 thousand hours), but also reduces noise and dust to zero. And even at maximum rotation speed the noise is very moderate. The high efficiency is confirmed by two certificates: 80 PLUS Gold and Cybenetics Gold, so that there is no doubt about it.

Zalman TeraMax II 1000W is a South Korean power supply, awarded with two prestigious certificates: 80 PLUS Gold and Cybenetics A-. The first means a high efficiency of 92%, and the second, on the contrary, a low noise level of 25-30 dB. The power supply also complies with the ATX 3.0 standard, which makes it compatible with GeForce RTX 4000 series video cards without any adapters.

There are black and white models to choose from, that is, for gaming and content creator PC builds. Moreover, even the modular cables are painted white, but the ventilation grille is always black. Excess wires will be stored in an elegant fabric bag. In the sleeping state, the power supply consumes only 0.5 W of electricity.

The progressive Active PFC 99% power correction method minimizes energy losses. Modern DC-DC circuitry separately stabilizes low-voltage lines +12, +5 and 3.3 V. Electrolytic capacitors are Japanese high-temperature capacitors up to 105 degrees Celsius, and solid-state capacitors are Taiwanese, which can withstand even higher temperatures.

The Thermaltake Toughpower PF3 1050W is a kilowatt power supply that is capable of delivering up to 600 W to a GeForce RTX 4000-series video card via a reinforced 12VHPWR cable. In addition, it has three 6+2-pin modular cables for the Radeon RX 7000 series. Also, the ATX 3.0 standard implies short-term double power surges, which the power supply must cope with.

Modern DC-DC circuitry is used with digital stabilization Load-Line Calibration and a solid Single Rail +12V line. All this ensures low ripple of up to 30 millivolts and high efficiency of up to 94 percent, for which the power supply was awarded an 80 PLUS Platinum certificate. But the acoustic comfort certificate is of a slightly lower level - Cybenetics Standard++, which means a noise level of up to 35 decibels.

But when the load on the power supply reaches 40%, the fan does not turn on at all. The Smart Zero Fan button allows you to switch between semi-passive and always active cooling modes. The fan has an FDB hydrodynamic bearing and an impeller with a diameter of 12 cm. Japanese high-capacity condensers provide a holding time of up to 17 ms.

be quiet! Straight Power 12 1200W is a German power supply with a premium Full-Bridge topology and an almost indistinguishable fan. A proprietary 135mm be quiet! Silent Wings with a funnel-shaped frame, aerodynamic grooves on the blades, 6-pole motor and hydro-dynamic bearing.

It is capable of operating in a wide range of 110 - 240 volts, so it can cope even with severe voltage drops in a household power outlet. All cables are modular, you can choose between 16-pin and 8-pin video card cables, and the processor cable is a full meter long. This allows it to be hidden behind the back wall even in a very large computer case.

The Platinum Energy Efficiency Certificate not only helps you save on your energy bills, but also minimizes waste heat generation at just 6%. And in standby mode, the power supply consumes a negligible 0.1 W of electricity. The use of the most durable Japanese capacitors allowed the manufacturer to provide a ten-year warranty on the power supply.
