ATX Network for Desktop PCs | c’t

Who stood out to Watt in PC-Netzteil?

Who knows who has found an ATX network for my individual desktop PC configuration?

The principle is one of the following: Add the maximum capacity of the PC components and switch it between 50 and 150 watts reserve. If the practice is in practice, it is a challenge to find most components that are not so light, which may well be in the Spitze jewels.

There are a few Vereinfachungen given. The larger processors are usually a main processor (CPU) and – fall – the graphics card (GPU). I think the hardware of all other components with working memory (RAM), mass storage (SSD/Festplate) and motherboard chipset are in weight. If you have one or two SSDs with up to 64 GB RAM, you can use a break of 20 Watts.

If the CPU cable is compatible, the maximum nominal power – generated Thermal Design Power (TDP) processor Base Power (PBP) – is no longer suitable for the Schätzung. Modern processors from AMD and Intel can last longer than ever before. With Intel processors of the 65-Watt class, there are 28 devices up to 200 Watt. With the 125 Watt type, the maximum turbo power is above 250 Watt. You can only use a power of 300 Watt to run the CPU. Heavy welding this extreme in BIOS setup could lead to motherboards, but this is not possible (Stichword: Configurable TDP). Furthermore, the calculation power drops slightly. It is also a fact that a power supply does not work more than a power of 350 Watt.

With the graphics card it is a fact that many repairers can use their own jewelry products. You can make a reservation for a reservation. More manufacturers of ATX network parts present on their websites Dimensioning calculator prepared (PSU Calculator, see ct.de/yvkt). There can orient themselves.

If you use the tipp, ATX networks are no longer dimensionable, you can save energy. Most PCs work with a larger part of the learning time and maintenance of the computer. But that is only gold with Einschränkungen. If an ATX network is efficient, it takes longer than 10 to 20 watts, but it depends on the ability of a person to charge it.

Who needs a 250 Watt power supply anymore?

My frugal office PC is supplied with 200 watts of its own power. If I now find an ATX network with 350 watts of power in online trading – what?

In the market of desktop PCs, notebooks dominate. All mini PCs with mobile devices are reliable. If you have a classic desktop PC in ATX design, you can use a graphics card and use a large network. A 500 Watt power supply costs around 25 Euro. While most people pay attention to the eighth prices, the vulnerability sinks after the schwächeren of the Internet.

Meaning of the Apprenticeship

If you are doing the energy partipp, it is all possible with desktop PCs to get the learning experience. Will my PC be used when I play my part?

Modern PC processors are sliding the inside of the seconds bridges, when they are no longer suitable. If the text transmission is over a longer period, the CPU core can increase the taste of the taste, for example if these tips. The middle value of the performance requirement lies with the typical PC-Nutzung which is not in the learning value as maximum.

If you have used a computer for 230 days a year for your 10 hours – also 365 days of extra weeks and 30 days of vacation -, then it is 2300 days ago. At 15 watts in learning capacity, 34.5 kilowatt power (kWh) corresponds to 30 watts on 69. The difference sums up at 30 cents per kWh to more than 10 euros annually, also to around 50 euros over five years of useful life. Compound: A gaming PC, under the last 200 watts freshest. If you can play for 10 hours and put in your sons, a year 520 kWh changes for 156 euros. In addition to the gaming PC, it also took more time, because the roads are not proportional to the electricity costs.

12VHPWR and ATX 3.0

Is my gaming PC a network with ATX 3.0 specification and with 12VHPWR cable?

That depends on the desired graphic card. Cards are rewarded with a prize of 550 Euro – a purchase at Nvidia GeForce RTX 4070 – a purchase for 12VHPWR plug. Many people lie about the adapter for the PCIe power plug with two or eight poles in.

If the network is strongly developed, the graphics card is opened with stable adapters. There can be a Drahtverhau option: Manchen High-End cards, the über 400 Watt fressen, lie Adapter for four eight-pin PCIe cable at. It is a crazy construction that can count on a network with 12VHPWR outputs and ATX 3.0 in the fall. Please note, it is important that the impulse loads are lifted.

Length of the power cord

Should I buy an ATX network on the long low voltage cable?

Yes, it is best if you use a relatively large amount of ATX devices. When the network has a new setup or the Main-Power-ATX connector of the motherboards, the platform is no longer suitable, so the cable length when using the power supply is no longer possible. I think the motherboard is a problem and can show the correct cable length before you get a network damage.

Network components with DC-DC technology

Have you ever used DC-DC technology on ATX networks and was it even available?

If there are ATX network transformer towers, the Wicklung can perform more functions on the unused voltages of 12 volts, 5 volts and 3.3 volts. With this switching technology, the latter situation can be a certain voltage range and the tolerance limits are of plus or minus 5 beziehungsweise 10 percent rated.

ATX power supply with DC-DC technology can be applied on the main rule: you can use a strong 12 volt wall charger and a DC voltage (direct current, DC) on 5 and 3.3 volts on switched wall chargers. In practice, the ATX network technology is so heavily loaded that the theoretical advantages of the DC-DC technology can simply be implemented.

ATX12VO technology

There are very few desktop PCs that use the ATX12VO specs – and few components have been found. Gibt es die nog?

With “ATX 12 Volts Only” (ATX12VO) mains protections 12 volts and other voltages with 5 and 3.3 volts are nice. Therefore you need special ATX12VO power parts as well as compatible motherboards. It is not that everything does not work.

Black gibt is one of the larger PC brands devices with jewel-like properties of 12-Volt-Technik, which is also often less frugal. If you use a new device, there are no power parts and motherboards with ATX12VO on the market. For a normal ATX power supply, an adapter cable can be used – but then the own ATX12VO fork falls away, without a view of the adapter sockets for 5 and 3.3 volts.

If there is a more economical desktop PC, then mini PCs with mobile devices are no longer suitable. Daher is the market niche for ATX12VO small.
