TOP 5 power supplies for GeForce RTX 4090 and Radeon RX 7900

be quiet! System Power 10 850W is a long-awaited update of the younger series of power supplies from the eminent German brand. At a consistently moderate price, the novelty has received a number of pleasant improvements. Cables are still modular, but now flat and soft, which helps them to be neatly laid inside the PC case.

Capacitors remained Taiwanese Teapo, but now belong to the high temperature series 105 degrees Celsius. But the manufacturer of the electronic filling has changed: instead of HEC, CWT is used. Thus, be quiet! unified its circuitry for one OEM partner. Recall that earlier there were be quiet! still based on FSP.

An efficiency factor of 85 percent results in an 80 PLUS Bronze energy efficiency certificate. The Yate Loon fan was replaced by the branded be quiet!, albeit on a simple plain bearing. But up to 50% of the load on the PSU, the turntable is not audible at all, and even at full 100% it is much quieter than its competitors.

2E Gaming Extra Power 850W is a power supply unit of a young Ukrainian brand with a solid 80 PLUS Gold energy efficiency certificate, which means efficiency up to 92%. And the reactive power compensation factor Active PFC is completely equal to the maximum possible 99%. The cable design is fully modular.

Even the main wires are removed: 24-pin for the motherboard and 8 + 8-pin for CPU. There are a couple of video card cables, each with two 6 + 2-pin connectors. This allows even a bunch of CrossFire, SLI or NVLink video cards to be powered. Or one flagship vidyuhi, for which you need three connectors at once.

The circuitry is progressive DC-DC Single Rail, that is, with a powerful solid +12 V line and independent voltage stabilization of +5 and 3.3 V. The capacitors are made in Taiwan, and the 14 cm fan is based on a durable hydrodynamic bearing. All possible levels of electrical protection are implemented: from short circuit, overload along the lines, surges, and vice versa, voltage drop in the outlet.

Zalman TeraMax 1000W is a fully modular, kilowatt power supply with a gold energy efficiency certification from a South Korean brand. And when the PC is turned off, but connected to the outlet, the power consumption of the PSU does not exceed 0.5 W. In addition to the generally accepted electrical protection, overheating protection is also implemented.

However, the power supply will certainly not overheat, thanks to the 12 cm fan on the FDB bearing. The manufacturer claims a fan uptime of at least 50,000 hours. Increase the durability of the PSU and one hundred percent Japanese capacitors, both high-voltage holding and low-voltage filtering.

There are three power cables for video cards, each with two 6 + 2-pin connectors. Able to work PSU with input voltage from 100 to 240 volts. In theory, this means support for European and American 115 and 230 V power grids, respectively. But in practice, it helps to cope with strong input voltage drawdowns, which especially often happens in country houses.

SeaSonic Vertex 1000W - a series of gold and platinum models from the main innovator in the power supply market. In the second case, the efficiency reaches an impressive 92%, and the voltage deviations along the lines do not exceed 3%. The warranty is, not much, not a little, 10 years. Based on SeaSonic's proprietary circuitry.

The cooling system is hybrid: up to 30% of the PSU load is cooled passively, that is, completely silently. Then the fan turns on and gradually increases speed as the load on the PSU increases. But even with a 100% load, the noise level does not exceed 20 dB, which does not stand out from other PC components. There is a switch button for constant active airflow in the summer heat.

The fan bearing with a diameter of 13.5 cm, of course, is hydrodynamic, and the input voltage range is wide 100-240 V. The cables are modular and there is already a modern 16-pin connector that allows you to connect video cards of the GeForce RTX 4000 series without adapters. This new PSU standard is called ATX 3.0.

Chieftronic PowerPlay 1200W - a platinum power supply with more than a kilowatt power and at the same time with a compact size. The length is only 16 cm and this is already taking into account the modular wire connectors. Chieftronic is a gaming sub-brand of Chieftec. It is based on the older modification of the CWT platform, the traditional partner of Chieftec (although alternative High Power and Sirfa are sometimes found).

The power supply unit weighs a gigantic 3.5 kg, which is explained by the presence of large radiators that provide passive cooling at low load. For better stabilization, electricity is supplied to the processor and video card via two separate lines + 12V1 and + 12V2. As many as four pieces are available for powering video cards.

Simply put, on the basis of such a PSU, you can assemble a super-powerful gaming PC, a workstation for 4K video editing or 3D modeling, and even a small mining farm. Japanese capacitors minimize current ripple. And extra cables are offered to be stored in a convenient fabric bag closed with Hook-and-loop.
