A 750W supply doesn't increase server stability - that's what redundant PSUs 
are for.
Plus: there are sh!tty 750W-PSUs otu there as well - numbers mean jack.

Yes? What about that? All tech questions regarding file servers and raid 
setups on Linux. Don't see how I go about how my Radeon makes the 10k barrier 
in 3Dmark.

Nuff said.
