An Even Closer Look:
In terms of overall aesthetics, the Fatal1ty B85 Killer resembles quite a lot with its bigger brother; Fatal1ty H87 Performance. They both share same kind of size and even the heatsink design. There are two heatsinks on the board; one for the CPU VRM while the second for the B85 PCH. Both the heatsinks have a very elegant black brushed aluminium finish.
It comes with a 6-phase power delivery for the CPU which gets its power from the 8-pin EPS connector. The power delivery circuitry obviously isn’t very powerful and robust as expensive boards but it should do fine with normal overclocking.
In terms of third party chips, the Fatal1ty B85 Killer doesn’t come with much. Right next to the bottom PCI slot, we’ve the ASMedia ASM1083 controller which is responsible for providing the legacy PCI slots. As the Z87 doesn’t support legacy PCI natively, this controller provides these slots by taking one PCIe x1 lane.
Moving to the left edge of the motherboard, we’ve the Nuvoton NCT6776D super I/O chip which provides the motherboard with hardware monitoring abilities and the PS/2 port present on the back of the motherboard. Right on the top of the super I/O chip, we’ve a little shield with Purity Sound logo on top. It’s actually an EMI shielding for the Realtek ALC1150 chip present under it. This chip is accompanied by two TI NE5532 amplifiers; one of which acts as differential amplifier while the other one as the headphone amplifier. According to ASRock, this configuration supports headphones with up to 600 ohms of impedance. This is quite an impressive sound solution for a motherboard belonging to this price bracket.
Near the CPU VRM heatsink, we another metal shield with Killer E2200 logo and it obviously hides another important feature of this board; the Killer E2200 gaming NIC. Near the HDMI port on the back I/O, ASMedia’s ASM1442T TDMS level shift chip is present which brings the HDMI port of the motherboard.
CPU pulse width modulation (PWM) is done by the Intersil ISL9582 controller present near the CPU socket. It controls and protects the integrated voltage regulator present inside the Haswell processors. As per its specifications sheet, it’s a low-cost 4-phase solution with hybrid digital design. This exact same controller is present in the Fatal1ty H87 Performance motherboard.
