I have a 550w power supply and my current system is:
-ASUS P8H61-M LE
-Intel Core i5 2400
-Asus ENGTX 560 TI
-A mediocre optical disc drive
-Western Digital WD10EZRX 1TB 7200 rpm SATA 6 HDD
550w power supply is enough for my current system but I want to replace my motherboard with an ASUS Sabertooth z77 motherboard. My question is when I change my motherboard to sabertooth will my power supply be enough to run the system?
