If it was a cheap case, the power supply was cheap, too.

By the time you add a pair of high-end graphics cards (SLI), a
high-end processor (high clock speed, multi-core), and lots of
hard-drive capacity (like a RAID configuration), it's possible to
push average power consumption to 600W or more. An 1100W supply is a
BIT over the top, but the more margin, the better-- as long as the P/S
is efficient and has a low power factor.
High-power supplies have more drive connectors-- and usually have
multiple +12V supplies internally to split up the load. Mass
quantities of hard drives draw a LOT of peak current when they first
start up...
