I bought an MSI RX460 4GB to use on my Lenovo H50-50 with 280W stock PSU. I've read before on forums and sites that "all PCI-E slots supply 75W as standard". There are no markings on the motherboard itself. GPU-Z 2.9.0 displays "Board Power Limit: 48 W" on advanced tab. I run tests and consumption does not exceed 48-50W even when GPU seems under %100 load. Does that mean my PCI-E slot can not, will not in any case provide 75W? Will I be able to benefit fully from this video card? Should I return it? Thanks in advance.
