  1. Gamemax GX-850 PRO: блок питания, который не стыдно поставить в дорогую сборку

    Когда ко мне в руки попал Gamemax GX-850 PRO – мощный, в белой расцветке, да еще и с поддержкой ATX 3.1 и PCIe 5.1, – я сразу вспомнил старые истории о "китайских БП, которые взрываются" . Но... решил дать шанс, тем более что на данную модель дают 10-летняя гарантию аки на какой-нибудь Corsair. Да, и потом..., у каждого производителя бывают удачные модели и не очень. Давайте разбираться, что же внутри этой коробки и стоит ли доверять ей свой компьютер.

  2. Bei diesem Standard sind wohl sämtliche Tests während der Entwicklung ausgeblieben.

    Immer schön, wenn Kunden als Tester verwendet werden. Quasi Bananen-Hardware, die beim Kunden reift.

    Bin mir sicher, dass mein Konnektor gerade genug verlegt ist um das Problem der erhöhten Widerstände zu umgehen...

    Schätze, ich werde es irgendwann herausfinden.

  3. computer PSUs need a new higher voltage rail to deal with e.g GPUs and other high power devices.

    It may sound weird but a 50v rail would make things more efficient AND safer, AND would allow for further expansion more easily.

    Because the thing that melts those 12v HPWR connectors isn't voltage. It's amps.

    if we'd increase the voltage by 4x we decrease the current by 4x. Cable and connectors would get much less hot.

    And it's easier to design efficient GaN power conversion

  5. It's 202(1,2,3,4,5,6) and NVIDIA's greatest innovation is convincing people that having a fire hazard so prevalent there is now an aftermarket of cable failure monitors is the pinnacle of a gaming PC build.

    I am continuously befuddled by people spending the equivalent of several months of wages to potentially burn down their home.

  6. PC prediction, slightly going out on a limb: with 12VHPWR / 12V2x6 connectors still melting, PC power supplies and high-end GPUs will switch to using a higher voltage to feed the extremely power-hungry beasts. Probably 24V, but they could go higher.

    With the cards already doing DC-DC conversion down to much lower voltages for the GPU and memory, there's no need to stick with 12V, and doubling the voltage will allow them to cut the current needed in half -- and since it's the high current levels that is causing all the thermal issues, it's an obvious fix.

  8. Jensen Huang would rather do this monstrosity than admit his 12 volt high failure connector needs to go to hell (or seek therapy).

  9. Как правильно подключить разъемы 12VHPWR и 12V-2x6, чтобы видеокарта не сгорела и не оплавилась

    История с печально известными разъемами 12VHPWR, которые начали плавиться на первых RTX 4090, казалось бы, должна была уйти в прошлое. Новое поколение видеокарт, обновленные стандарты питания – и проблем больше нет, так? Не тут-то было. На форумах до сих пор регулярно появляются истории несчастных обладателей топовых графических ускорителей, которые обнаруживают у себя расплавленные коннекторы. А с появлением RTX 5000-й серии и разъемов 12V-2x6 ситуация, похоже, только усугубилась. Давайте разберемся, почему это происходит и что нужно сделать, чтобы ваша новенькая видеокарта не стала очередной жертвой некорректного подключения.

  12. Langsam k... es einen an, dass #nvidia mit ihren Spezifikationen so hart an den Grenzen zur Gefährlichkeit hantiert, dass selbst korrekt und voll eingeschobene #12VHPWR (12V High Power) Kabel mangelhaften Kontakt haben können, dadurch auf einzelnen Adern Temperaturen von 100°C und mehr möglich sind und es in den eigenen Karten (Founders Edition) keine elektrische Absicherung dagegen gibt. youtube.com/watch?v=puQ3ayJKWd

  13. I think they should ban the 12 VHPWR connector due to being too dangerous. Can't have the card be powerful enough without it? Too bad! Increase efficiency.

  15. As per youtu.be/MWsVbYZcZ4U Gamers Nexus are doing a survey about GPU power cable (not only 12Vhwpr) hardware issues -> geni.us/gpupwr (redirects to a Google Form).

    You can fill this out even if you've never had any issues, I haven't.

  17. Schmorende Stromanschlüsse bei den GeForce-Grafikkarten der RTX-4000-Serie sollen primär an falsch eingesteckten Kabeln beziehungsweise Adaptern liegen.
