7770 on 400W psu?

[asdjei]

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.
Thanks

I think it's going to be fine, but I recommend you to not try OC'ing at all. I know you don't want to but I am warning you again.

You'll be fine. Cooler Master PSUs are generally of average quality.

The i5 is a 77 watt part. The 7770 is a 110 watt part. 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.

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?

I use Cooler master extreme power plus 600 watt with gtx 650 ti ASUS and no problems
