Using 2 PSU has CLoD kicking it in high gear!

Thanks for the info Druid.. I only have a 600w PSU and hope that is going to suffice for now..

Another thing to think about is some cheaper psu have far less output than what they claim to have. Also cheaper units can have power surges that can at best crash a game and at worst wreck your computer. The power can drop then spike due to things like the fridge starting.
I am a novice at best when it comes to building computers so I did alot of research in every component. One thing I learnt in my latest build was the psu is as important as any other component. In fact most builders will tell you to use a psu much bigger than you need as chances are you will add components to your pc at a later time.

Well, I've been to the shops and the best I could do was a OCZ 700w off the shelf (patience was never one of my virtues).

Will fit it tonight and run some tests on the Black Death track and see about performance change.

I have plenty of Fraps benchmarks on file from the old psu, so I'll do some comparisons.

Having said that, it won't bother me if there's no change as I'll still need the Psu if I upgrade the card.

We shall see!

PSU must be able to maintain regulation under load, my recently replaced 750W dipped to 11.5V when launching missions in CoD and the GPU would not render correctly.

I tried it as an additional dedicated GPU supply but the rugulation is fubarred. The replacement coolmaster provides good steady 12V regualtion under load.

If you have two known good PSU's (and space to fit) I don't see why you shouldn't connect them in tandem to share load, just make sure that the common rails are tied together (usually most PSU's 0v is connected to the PSU casing and if both are bolted to the steel casing both PSU's should have a common ground 0v).

The only concern I would have are possible effects of having some 12V and 5V rails being present at slightly different times during switch on (unless you can get the mobo to switch both on at the same time).

Interesting thread.
