Intel C2D E8400 3.0GHz
Asus P5Q-E Motherboard
512MB XFX 9800GTX+ DDR3 256 bit Graphic Card
2X2GB Team Elite DDR2 800MHz RAM
500.0GB Seagate S-ATA harddisk 32MB
Silverstone Strider 560W PSU
Pioneer 20X SATA DVDRW 216BK
Cooler Master ATX Casing RC 690
3X12cm CMaster cooler fan
1X8cm CMaster cooler fan

is that my PSU enough to do Overclock?
if i added CPU cooler and added 2X2GB Team Elite DDR2 800MHz RAM
is that enough for overclocking my computer to highest performance ?

but 9800GTX+ GC use a lot of Wattage, do u think so ? is that really enough ?

Did anyone know that Gigabyte Ordin Pro 800 PSU specification and is that Real Power 800W PSU?
Is that this PSU suitable for overclocking ?
Is that good quality ?
If this PSU not good, any suggestion pls give me reply, thx
