Closed HD 7750 or 7770 Tags: Graphics Cards AMD HD Graphics Product Last response: September 16, 2012 10:00 AM in Graphics & Displays Share Alicek September 15, 2012 10:11:32 PM Hello, I'm uncertain whether to get the 7750 or 7770 Mainly because my PSU is a 400W LiteON http://www.ascendtech.us/liteon-ps-6401-3-400-watt-powe... I've seen some places say 420W for 7770 but the AMD site says 500 or greater. If this helps any http://www.newegg.com/Product/Product.aspx?Item=N82E168...

Angrynerds September 15, 2012 11:55:59 PM I believe the 7750 doesn't require an external power connector but the 7770 does.

So I could get an HD 6850 if I really wanted? Alicek September 16, 2012 4:28:17 AM Best answer selected by Alicek.
