I need to ask i just orderd a new cpu to my computer, a Phenom II 1055T and the rest of my system is:
ATI 4870 1GB
3 GB DDR2 800 @ 960 mhz (2x1GB + 2x512mb)
3 HDDs two in raid0
1 DVD /RW drive
And currently a Phenom x3 8400 @2.52ghz. new next week
Asus M4A78 Pro motherboard.
(also have a new cpu cooler named NorthQ 3580) water cooler.
I have an all most unknown PSU brand named "LC TITAN POWER" and i just want to ask the 12v rails goes to the CPU/GPU right? and two 12v rails with 18 ampere is that enough power, to power both the CPU and GPU? im thinking of overclocking the cpu..?
And how can i messure the 12v rails if there even comes 18 amps out of them?
Assuming decent quality (doubtful with that brand), the PSU has enough capacity to run your system.
I have a similar system in terms of power demand: (GA-EP45-UD3P | Q9550 OC'd to 3.6 GHz (425 MHz X 8.5) | 4 GB RAM | 3 HD's | GTX260 (close to same power requirements as a 4870)). It pulls 300 watts from my TX750 PSU. So you should be all right.
Without some fairly expensive equipment, it is almost impossible to load test a PSU at home.
