  Non-Standard Interactions (NSI) between neutrinos and matter affect the
neutrino flavor oscillations. Due to the high matter density in the core of the
Sun, solar neutrinos are suited to probe these interactions. Using the $277$
kton-yr exposure of Super-Kamiokande to $^{8}$B solar neutrinos, we search for
the presence of NSI. Our data favors the presence of NSI with down quarks at
1.8$\sigma$, and with up quarks at 1.6$\sigma$, with the best fit NSI
parameters being ($\epsilon_{11}^{d},\epsilon_{12}^{d}$) = (-3.3, -3.1) for
$d$-quarks and ($\epsilon_{11}^{u},\epsilon_{12}^{u}$) = (-2.5, -3.1) for
$u$-quarks. After combining with data from the Sudbury Neutrino Observatory and
Borexino, the significance increases by 0.1$\sigma$.
