Ok, my gaming rig and my media rig need new power supplies (which they seem to always need). I decided to NOT go the el cheapo "Hey, look what Pricewatch has for $14" route this time and head over to Newegg. I see this Coolmax one for $30 and this Thermaltake one for $40. Now, I know these are some good brands despite the cheap price, but my concern is the power output.
Is 400w really that much output? I usually buy in the 550+ range just to be sure, but I've seen one of those "how much power" estimators and it had my gaming rig actually UNDER 300w (Athlon XP 3400, 1GB RAM, GeForce 6600 GT, MSI Neo4 board, single DVD drive). Are there any "dead on" estimators out there? Is my fear of this low wattage justified?
