Closed 7770 on 400W psu? Tags: Graphics Cards Intel Graphics Last response: March 3, 2013 2:10 AM in Graphics & Displays Share asdjei February 28, 2013 6:28:58 AM Hello everybody, I have a system with a Cooler Master RS400W PSU. Is that sufficient to handle a Radeon HD 7770? My system specs are : Intel Core i5 3470 Intel B75 Mobo 4GBx2 RAM 22" Samsung 1080p monitor Will this PSU be able to handle the added load of the 7770? I'm not planning to do any sort of overclocking whatsoever.

I know you don't want to but I am warning you again. jaguarskx a c 353 U Graphics card a c 106 å Intel February 28, 2013 1:05:38 PM You'll be fine.

Add in 50-75 watts for the board and drives and all the other parts and your at around 250 watts. You should be good. asdjei March 2, 2013 1:18:37 PM are you sure? I've asked around, some people are saying that cooler master isn't the best manufacturer of PSUs... also, could this handle a 7850/6850 or a 650Ti? sam1911 March 2, 2013 1:26:47 PM asdjei said:are you sure?
