Unhappy Cablu PCI Express 8-pin pentru sursa modulara?

salut! pe scurt:

sursa:

Super Flower Golden Green 800W cu alimentari pci-express:
- 2 x 8pin
- 2 x 6pin


placi video:

- GTX 1080 care necesita 1 x 8pin + 1 x 6pin
- GTX 1080 Ti care necesita 2 x 8pin

intelegeti problema, nu? am alimentat Ti-ul cu cele doua 8pin-uri, iar pentru 1080-ul simplu mi-au mai ramas doar doua 6pin-uri, cand eu am nevoie de un 8 si de un 6. bun, Ti-ul a venit cu un adaptor de 2 x 6pin --> 1 x 8pin, dar si asa imi lipseste o alimentare 6pin.

ce este frustrant e ca sursa este modulara si nu am folosit nici jumatate din sloturile ei... pentru ca nu mai am cabluri! as putea foarte simplu sa mai conectez un cablu 8pin direct in sursa, doar ca nu il am. stiti cumva daca pot comanda astfel de cabluri separat? sau chiar sunt fortat sa cumpar alta sursa?

multumesc!

PS: stiu ca sunt adaptoare SATA -> pci express 6-pin, dar din moment ce placa isi va trage toti cei 75W / 6-pin, nu e o idee buna adaptorul in acest caz.

thanks for being helpful

sursa e din 2014, este inca in garantie si ar duce lejer ambele placi, DACA ar avea cablurile necesare. dar multumesc pentru timpul / efortul de a face poza!

Adaptor de la 6 pin la 8 pin.
1080 poti sa il pui leger pe 6pin+6pin, ca nu sare de 225W.

intrebarea e daca merge si daca pun placa pe un pcie riser, cu adaptorul asta. pt ca imi consuma aprox 170W la mining. iar 2 x 6pin ii ofera 150W, nu? iar riserul va fi alimentat pe cablu de alimentare SATA care, din cate stiu eu, nu e conceput sa ofere mai mult de 20-30W. multumesc mult pt sugestie oricum, la asta nu m-am gandit!

Pusa in slot pcie x16 placa poate sa traga teoretic 75w prin slotul pcie si 75w+75w din 6+6 pin, adica 225w.
Despre risere si alte improvizatii nu ma pricep.

Ar trebui sa mearga fara probleme, iti trebuie 1.5mm^2 de cablu sa treaca 14A pentru placa video.

Mufele implicit cablurile alea is facute sa tina OC nu underclock/undervolt.
