Every time I hear about Sparkle PSU, I cringe and get mad. I got one of their 350W models and that thing was a piece of crap. It would work fine until you turned the machine off. After that, you had to pray to God and offer a virgin sacrifice to get the thing to turn on again.
Probably just a dud. But then I tried to RMA it and the frickin company shipped it back, said that there was nothing wrong with it, and charged me the shipping.
Sold the thing to a friend and the same thing happened to him. Now it is nothing but a good door stop.
Sorry, just had to express my experience.
But BigBen, it looks like your best bet is to get 3 300W PSU and just do it. At least then you can sleep well at night knowing that if one fries, it wont take the system with it.
And yes, I am a college student so I KNOW all about the "no money" situation
EDIT: How about this; college student with Child Support due every month. Can we say POOR BOY HERE!!!
