I'm building a budget gaming rig for my younger brother, max I can spend is $550 (Aud) not including mouse, keyboard or monitor.
Here's what I have come up with so far, I will be purchasing parts in a couple weeks time.
CoolerMaster Elite 341 with 420W PSU - $59
Intel Core i3 2100 - $115
ASUS GeForce GTX 550 Ti 1GB DirectCU - $129
WD Caviar Blue 500GB - $79(!)
Corsair 4GB RAM 2 Dimm 1333MHz CL9 - $29
ASUS P8H61-M-LX-V3 - $65
Wireless PCIe card - $19.50
My question is, will that PSU (Coolermaster TM-420-PMSR 420W) have enough amperage to be able to handle that setup? Apparently it only has 16A on a single 12v rail (as opposed to 53A on a TX650 v2 which I have). That's quite a difference and I'm worried the computer won't run well or the PSU will die.
If not, could someone tell me what the minimum amperage is that I should go for in that setup? I want to keep cost to a minimum hence why I chose the case/psu combo in the first place, but if I have to get a different psu I will get a cheaper case and as cheap as possible psu.
