My last computer (an old pre-built from Acer) had it's PSU die, the new PSU I got for it turned out to be the first piece of the rig I'm building now.
When I got it I told myself I wouldn't do any over-clocking or SLI/Crossfire, so I figured 500 Watts would do me fine. It's a nice gold+ rated LEPA and everything. But I did some searching on google and found this calculator that worries me. http://support.asus.com/powersupply.aspx
With the following...
Core i5 2500K,
GTX 560 Ti,
4 dimms of DDR3,
1 hard drive,
1 DVD drive,
no USB peripherals,
and 5 fans (I actually have 6 in my case but I only have cables to power 5 of them).
The minimum recommended power peaks at 550W... If I want to throw in an extra HDD or some external USB hard drives the needed power jumps up to 600W. I'm... very surprised at this, because I was sure you didn't need this much unless you started playing with multiple graphics cards. I looked it up and the i5 peaks at 131 W, while the 560 Ti supposedly requires 170... I'm not sure where he's getting the other 300 watts.
Is this caluclator exaggerating? Or is 500 W really not acceptable for my situation?
