    Corsair 18AWG Cable for 8pin to dual 6+2pin power supply

    ONSA Plus | 22.03.2023 |
    Corsair 18AWG Kábel pre zdroj 8pin na dual 6+2pin
    Dobrý deň, nie, nejedná sa o origninál. Kábel má však rovnaký pinout (type 4), teda pasuje na zdroj a dá sa bezpečne používať. Je dôležité overiť kompatibilitu s Vaším zdrojom na stránkach výrobcu.

    spoľahlivo funguje už viac ako 4 roky. v nastaveniach sa da krásne nastaviť podmienky. dobre funguje aj s 6x1kw špirálami, zapojenými paralérne. po zapojení si sám zmeria špirály. od marca do novembra mam dosť teplej vody ak nepoužívam bazén. menič najpr dobije baterie a potom dáva prebytky do akumulacky.
