Graphics card and PSU Needed

[Skud]

Buddy recommended smps for 6770 is 450w. Check properly. Also 6790 is way better than 6770 but also have higher power requirements. For your monitor 6770 is more than enough.

HD 6770 requires one 6-pin PCIe connector whereas HD 6790 requires two. VX450 has only one 6-pin PCIe. If you get HD 6790, you will also need Molex to 6-pin converter.

SO...Making 6770 my Final.....which the retailer says will cost 7500 in Kolkata.

Should I take the risk of the 6790 with my 450 watt PSU? or should I stick with 6770? Would It be safe to take with my VX450?

VX450 can handle even a 6950...
U are completely safe....

New problem....one of the retailer told me that 6790 is available at Rs.7950....whereas 6770 is not available, but the other retailer who have 6770 is charging Rs. 7500 for 6770...

If I go for 6790, am I taking a risk with my VX450 as the AMD site tells me that it requires 500watt PSU with two PCIe 6 pin connectors whereas VX450 is a 450 Watt with only 1 PCI e 6 pin connector.

I read that VX450 can operate with 570W max voltage and Crosair has given a minimal rating of 450, it can even be termed very well as 500/550 watt PSU.

have a look at this too..

The other problem is with the connectors, does every 6790 card comes with a molex -> 6pin PCIe adapter cable ..??

Waiting for reply. Thanks in advance.

Better save 500 bucks and get the 6770. Bargain with the other retailer for some discounts.

there's is not a major difference in performance between 6770 and 6790
however the latter is power hogging unit

6770 is better here in terms of performance per watt value
