PC Locks up

[pevergreen]

Pape-san, sorry to sound lazy but, I have an Intel Core i7 920, 2 GB DDR3 RAM, 4 hard disk drives and a 9500 GT and I'm thinking of upgrading to a non-SLI/Crossfire DX11 supported video card which will need to be powered additionally from in the inside by the PSU.

I currently have a Thermaltake 500W however I doubt it'll suffice when I make the change. Could you give any ideas about how much watts to go for and, if possible, a particular brand ?

I'd go 650W, maybe 700. Better higher than lower...

Interesting, just used the Antec Power Supply Calculator, said that system would be around 295W maxed out, with a new video card...don't know.

My current setup apparently drags 341W max. (2 WD Green HDD, 1 DVD RW, 1 Blu-ray Drive, 6 DDR3 sticks, 275 graphics card, i7 860.)

I have a 750W PSU...
