2 psus

[mjsharma]

may b stupid.. but i was thinkin can v connect 2 psu to one comp?
some video cards draw hell lot of power and recommend 650w psu and all....in such a case can v connect one 450w psu just for gpu and rest powered by a 300w psu or something like that..??
cos 450w and 300w psu are really cheap as compared to higher ones...
so, can v run a comp like that?

Yes you can, but its generally a pain. There is a reason bigger ones are made. I've seen the Corsair on sale for $40 after rebate. Keeping in mind you can get one per household/person this means you'd need to spend ~$100 to get two. Why not just buy the bigger one?

yeah u r rite... y not go for a bigger one?
i live in india, here its like u ll get a 450 w corsair psu for 4k rs but a 850w corsair for 11k, 2 corsair 450 ll cost u only 8k rs which is 3k less than 850w corsair, so isnt it a better way?

There's a cable you need to be able to connect the two PSU's together, I can't for the life of me remember what its called.

Google it.

Problem is buying that cable in india. You could rig a momentary contact switch and start it manually. You'd wire it pins 14 I think and a ground. I think its pin 14 or a green one. If its powering your GPU and drives I'd start it just before you start the main PSU. If your good, you might even be able to wire both up to your case switch.
