MSI Radeon HD 7770 Power Edition review - Product Showcase

Connectivity wise the output connectors will vary per brand. MSI equips the card with a display port connector, HDMI and a Dual link DVI connector. So all the bases are covered. The R7770 has a power consumption of give or take 80~90 Watts. The boards overall power consumption from idle to load is excellent really. Expect an idle wattage of roughly 10 Watt and when the monitor goes into power save mode, the card throttles down even lower towards 3 watt.

Here we can also see the cooler a bit better. Heatpipe based with a fan(s) blowing over the aluminum heat sink. The cooler is performing nicely and the overall noise levels are non existent.

You will need to hook the 7770 up to your power supply with a 6-pin PCIe PEG connector. We recommend a 500 power supply to start with, with one card of course. You could opt to go with two cards in crossfire mode as there is one Crossfire connector available on the card.

The backside of the card reveals very little, a fairly simple  PCB design.

Here's the PCB with the cooler removed. Let me remove that thermal paste a little and zoom in at the GPU:

There we go, that's Cape Verde and it clocks in at a steep 1100 MHz on this model. But let's talk a little about the architecture for a minute, next page please.
