First of all, we need to separate the terms and standards before we should even think about buying a new ATX 3.0 power supply. And to bring it right at the beginning times to the point: Panic buying is completely out of place and more or less intentional marketing! Or to put it more casually: in principle, no one needs the whole thing yet [...]

Thermaltake Toughpower GF3 1200W ATX v3.0 PSU Review – True 12VHPWR connector for NVIDIA’s big GeForce cards
Since the launch of NVIDIA’s top ADA models and the tiresome wrangling over the 12VHPWR connection, many enthusiasts are looking for potent power supplies according to the new ATX 3.0 standard. Thermaltake offers a real ATX v3.0 power supply with Toughpower GF3 1200W, which could be a serious alternative for many owners of a GeForce RTX 4090 [...]
Even though many enthusiasts are currently looking for potent power supplies according to the new ATX 3.0 standard (and hardly find anything on the market) after the launch of NVIDIA’s ADA top models and the tiresome wrangling about the 12VHPWR connector, the Corsair HX1500i together with the additionally offered cable including the 12-4-pin [...]
ATX 3.0, PCIe 5.0 and the new 12VHPWR Connector – Mistake, Misunderstanding or lazy Compromise with Backdoor?
It is well known that the specifications for ATX 3.0 and PCIe 5.0 are closely intertwined and many things have also found their way into each other’s standardization. Also the many articles I already wrote about the 12VHPWR connector, i.e. the 12+4 pin, already gave a lot of insights there. It can also be assumed that the new, powerful [...]
The new ATX 3.0 standard brings many innovations, especially since some things can’t be completely separated from the PCIe 5.0 standard. But even though they are different consortia, there is a lot of overlap that then finds its way into the other specification as well. After all, it’s basically about the same thing and of course you [...]
Cybenetics ATX v3.0 Spec Power Excursions Calculator – Freeware tool for power supply calculation according to Intel’s specifications for load peaks | Download
We have already discussed the topic of load peaks with the upcoming graphics cards including PCIe 5.0 as well as the new ATX 3.0 standard and Intel’s statements on this topic in detail several times. But since in the end no one really knows what to do with all these standards and theory in their own practice, my friend Aris (Dr. Aristeidis [...]
Seasonic Prime Fanless TX-700W – Innovative power supply, very solid components and a hidden design problem
The Seasonic Prime Fanless TX-700 is a new but quite expensive passive power supply bursting with superlatives. And yet there is a seemingly fundamental design problem that the layman cannot detect in this way and that can nevertheless lead to consequential damage to the connected hardware. Of course, I don’t want to anticipate the detailed [...]
Insights into ATX v3.0, ATX12VO v2.0 and PCIe 5.0 – When resource waste becomes the new standard | Investigative
The race for ever faster CPUs and above all GPUs is now producing such blossoms that even existing standards have to be softened or modified for the new energy waste offensive that soon every end consumer will have to save up for a portable nuclear power plant if they don’t want to be in debt with the energy supplier well into old age. To [...]
Who doesn’t know it, that moment of unbridled hatred when the power generally goes out. So when not only the fuse does its work, but the whole place suddenly goes dark? Storm or no storm, it doesn’t even have to be a direct lightning strike, which then gives the domestic electronics the final neck break. This is exactly what happened [...]
Having assembled quite a few PCs already, I’ve always wanted to build a mini-I-X system for everyday use. So it came as a call that my work colleague asked me for a new PC, well, the help to build him something tailor-made. After a short information gathering regarding the application of the PC as well as the budget, it was only a few mouse [...]
View behind the factory backdrops: This is how a power supply from Be Quiet is created! at the contract manufacturer (OEM) | Documentary
Since I’d like to go to the factories of the contract manufacturers and always try to take a look behind the scene, but just the cute little Corona virus lurks grinning behind every Far Eastern corner and i’m hämisch with a hearty “You can’t pass”, it must direct an older collection of images. The production is [...]
Bang frog, China-Böller, widowmaker – for the range of selected cheap cruelties from the Far East there are many harmless paraphrases. But that this electronic waste is literally fire-hazardous, I had to learn (once again) first hand during a short experiment. But trial makes you smart and so I didn’t let what I wanted to do without [...]
What is the real amount of work and know-how that goes into a modern computer power supply? We know the finished products, test and compare them – but that’s all. The forums are full of open questions and often enough the necessary transparency of the providers is missing. I was first allowed a semi-official look behind the scenes of a [...]
Corsair RM850x W (2021) PSU Review – Suitable gold piece for Rocket Lake and thirsty graphics cards?
After almost three years in production, Corsair has finally decided to update its popular RMx line to better suit the needs of today’s graphics hardware. There are again five models with capacities ranging from 550 W to 1000 W. All are fully modular and the OEM is still Channel Well Technology, as before. And since I’m not always just [...]
Detailed Test: Intel Core i9-11900K – power consumption and hidden load peaks – warning and all-clear for the PSU
We already know since my launch article “Intel Core i9-11900K, Core i7-11700K, Core i5-11600K and Core i9-10900K against Zen3 – Last man standing in silicon” that Intel’s 11th generation doesn’t act particularly squeamish at the power supply. But also not detailed enough, because there was one thing I couldn’t [...]
Special adapter with caps on the PCIe socket of the graphics card against load peaks – snake oil or miracle cure? | Practice
Load spikes that can cause even nominally adequate power supplies to suddenly shut down are all the rage right now, especially since the launch of NVIDIA’s current Ampere generation. It is also undisputed that this leads to the creation of legends and, of course, the accessories industry. But is there any point at all in placing a capacitor [...]
Is a 500 W PSU really enough? An AMD Radeon RX 6800 and a NVIDIA GeForce RTX 3070 against a be quiet! Pure Power 11 500 W | Practice
You’ve seen a lot of things, even on YouTube. For example, a 500 watt power supply miraculously survives even a GeForce RTX 3080, while exactly this card even forced a 1300 watt Platinum behemoth to give up in the lab before the Ampere launch. Well, NVIDIA has meanwhile defused the boost and thus also the load changes, but that should still [...]
Fireworks in the PC and purchase warning: Gigabyte’s current P750GM power supplies affected by total losses
The reports about failures of Gigabyte’s current P750GM are piling up and also my friend Aris Mpitziopoulos has already tested this power supply and, analogous to what you could read in the social networks, already had to dispose of it professionally with a capital complete failure and, after an also visually remarkable firework. The power [...]
Office and gaming in one PC? We build a gaming-ready office computer and marvel at Ryzen and Radeon | PC-Praxis
If you are in urgent need of a new computer, you have to put up with the extreme prices on the one hand and the limited availability of the components on the other. It’s annoying, but it’s not likely to change anytime soon. Because you can’t always choose the time of an upgrade, or the conditions never really fit 100% anyway [...]
When miners are mining, of course, really fat wattages come into play for the power supplies as well. Better efficiency in the masses is of course really fun and also generates a monetary added value. That's probably what the manufacturers of the China firecracker sold in the USA thought, too, as they gave their firecracker a snazzy 90-plus [...]
