Sapphire Radeon HD 7770 OC Vapor-X 1GB Graphics Card Review
The card from a first look is damn sexy, with a mish-mash of silver and black, with a hint of blue upon the dual fans, and bottom corner of the card. The card includes a dual fan design, with Vapor-X branding, and underneath we get a first glimpse of the vapour chamber design heatsink with twin heatpipe technology which spans to each end of the heatsink.
On the top of the card, the plastic shrouding wraps around the top and includes Sapphire branding upon it. The plastic cooler cover covers the whole card from top to bottom, from back to front and the two fans sit flush with the shrouding to give maximum airflow, with the quietest noise output.
On the end of the card, we find a single 6-pin PCI-Express power connectors. If your power supply doesn’t include the relevant connector, Sapphire bundle in a Molex to six-pin PCI-Express connector cable for you.
Moving to the top of the card, we find a single CrossFireX connector, for use with pairing this card with another HD 7770 for multi-GPU technology.
The rear I/O on the 7770 OC Vapor-X has been changed slightly from the reference design. We now find two dual-link DVI ports instead of just one, the HDMI port still remains, but instead of two mini DisplayPort connectors, we find a single full-size DisplayPort output connector. The rest of the rear I/O is taken up by ventilation slats where possible.
I dont understand why they recommend a 450-500 watt PSU when this card + entire machine clearly doesn’t eat up more than 192 Watts….
Marketing gimic ? plz explain ..
its a complicated mix of what other components you are likely to use, what kind of amps each rail of your PSU can deliver and whether your PSU is peak or continuous. Generally, manufacturers will give themselves enough of a safety net to make sure even if you have a rubbish 450W PSU it would still work.
