Under compatibility on the EVGA PowerLink product page.
It is listed as an 11G-P4-2389-BR.
(Got it as a refurb from EVGA so mine actually ends with RX.)
Unless your packaging actually has 2389-BR, you're in trouble.
If yours says "RX", it's not on the compatible list.
If EVGA goofed and gave you a different card..Well...A bit late at this juncture. And kinda pointless for a purely cosmetic issue.
