Reddit user DallasGrave, who recently soldered a dual 8-pin board<\/a> to an RTX 5090’s 16-pin header, is back with a more ambitious take on the same idea. The new “Quad 2×8 Header Conversion” mounts four 8-pin PCIe connectors right on the card, tapping the contact points of the 12V-2×6 header, so the 16-pin connector can either stay in use alongside it or be skipped entirely. Each 8-pin carries three 12 V conductors, which spreads the load over twelve wires instead of six.<\/p>\n

According to the modder, current per conductor is “almost perfectly halved” compared to the native connector, landing at roughly 4.1 to 4.4 A per wire at 600 W, with wire temperatures dropping by around 20\u00b0C. The sense pins are set for 600 W, and the board has apparently been tested up to 800 W on a shunt-modded card, where the PCB itself reportedly sat at about 45\u00b0C. Videos covering installation, live current data, and a 24-hour sustained load test are apparently being shot now, and custom backplates are in the works to make the mod look more factory-made. Versions for nearly every card, Founders Edition included, are also going into production.<\/p>\n

\"\"\/<\/a> \"\"\/<\/a> Modding efforts like this one continue to be made as reports of the 12V-2×6 connector melting pile up, whether on a reviewer’s RTX 5090<\/a> or during DLSS 5 testing<\/a>. Modders have also gotten the RTX 5090 running purely on 8-pin connectors<\/a>, while off-the-shelf safeguards haven’t fared much better. MSI’s yellow-tipped “safety-oriented” connector has shown burn marks<\/a>, and ASUS’ $50 ROG Equalizer cable<\/a>, sold specifically to prevent these burns, also reportedly burned. Even ASRock’s TempGuard failed to stop a meltdown<\/a> on a $15,000 RTX PRO 6000 rig.<\/p>\n","protected":false},"excerpt":{"rendered":"Reddit user DallasGrave, who recently soldered a dual 8-pin board to an RTX 5090’s 16-pin header, is back…\n","protected":false},"author":2,"featured_media":648845,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[6],"tags":[85,46,125],"class_list":["post-648844","post","type-post","status-publish","format-standard","has-post-thumbnail","category-technology","tag-il","tag-israel","tag-technology"],"_links":{"self":[{"href":"https:\/\/www.newsbeep.com\/il\/wp-json\/wp\/v2\/posts\/648844","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.newsbeep.com\/il\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.newsbeep.com\/il\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/il\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/il\/wp-json\/wp\/v2\/comments?post=648844"}],"version-history":[{"count":0,"href":"https:\/\/www.newsbeep.com\/il\/wp-json\/wp\/v2\/posts\/648844\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/il\/wp-json\/wp\/v2\/media\/648845"}],"wp:attachment":[{"href":"https:\/\/www.newsbeep.com\/il\/wp-json\/wp\/v2\/media?parent=648844"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.newsbeep.com\/il\/wp-json\/wp\/v2\/categories?post=648844"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.newsbeep.com\/il\/wp-json\/wp\/v2\/tags?post=648844"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
