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 [...]
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 [...]
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 [...]
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 [...]
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 [...]
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 [...]
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 [...]
Cybenetics was founded four years ago with the goal of introducing new efficiency and noise certification standards for AC-DC power supplies (PSUs) through its ETA and LAMBDA ratings. In these four years of being in business, nearly 800 power [...]
I have talked to Aris for a long time about this topic, because I also receive many mails every day with inquiries whether this or that power supply with configuration X, Y or Z would really work safely. Due to the lack of a wider range of suitable [...]
In the last few weeks I have been able to talk to some manufacturers who are all complaining (ok, it must always be like this) and try to hoard as much copper or semi-finished copper products as possible for current and future production. Of course [...]
2020 was actually a first-class year for technological innovation, but it will probably also go down in history as the year of the ultimate frustration of discouraged consumers, when the target group will end up not being able to buy what has been [...]
Who doesn’t know the great 80-Plus logo on most power supplies? This label suggests a certain efficiency and contributes not insignificantly to image building. 80 Plus Platinum? This just has to be good! Or maybe not so really? A document that [...]
The idea of testing power supplies not only synthetically on the chroma, but simply once in the usual setting of a possible user, is actually not even that absurd, but usually fails because of the amount of test objects. And where do you get these [...]
Well, that sounds more dramatic than it might be, although… The devil is in the test setup as usual. The MSI GeForce RTX 3090 Gaming X Trio (OC), MSI GeForce RTX 3080 Gaming X Trio (OC) and MSI GeForce RTX 3070 Gaming X Trio (OC) are tested on [...]
The discussions about what current flow various 6-, 8- or now even 12-pin sockets can survive are as old as these sockets themselves. But while over the years one could see the odd experiment or two, the 12-pin Micro-Fit 3.0 connector is new. This [...]
Since the new 12-pin sockets are so well known and one of the NDAs has fallen in the meantime, one should also clean up some of the rumours, mistakes and confusion. In the end, only a small communication lapse led to half of the power supply [...]
Who measures a lot measures crap. This rule applies as long as one does not actively deal with the circumstances and requirements and is not prepared to invest a lot – mostly private – time in its exploration. I started working more [...]
Almost 9 years ago, EuP and ErP were on everyone's doorstep, also in terms of power consumption in stand-by mode. That is why, as "Hilmar Brenninger", I had more or less investigatively thrown myself into the turmoil and checked [...]
The previous practice of real-time measurements (even over longer periods of time) only with the oscillographs is certainly not bad and it also allows deep insights into the switching behavior of graphics cards and CPUs due to the high resolution [...]
