its just about at its max...
140w for the cpu.
20w for the ram
120w for the gfx
40 for the rom burner.
20 for the hdd.
5-10w per fan...
20+w for the motherboard if your overclocking the cpu if not then 5-10
yeah your very close... to close i would say... consider swapping to a 550w minimum.
Agree with HEXIT in addition i would add don't buy cheap PSU Cooler Master does not supply good PSU get this XFX Core Edition PRO550W (P1-550S-XXB9) 550W ATX12V 2.2 & ESP12V 2.91 SLI Ready CrossFire Ready 80 PLUS BRONZE Certified Active PFC Power Supply http://www.newegg.com/Product/Product.aspx?Item=N82E168...
not true some of there psu's are very good. they use different manufacturers some better than others. same as thermaltake. i have a toughpower 850w and its just as good as a seasonic but there 550w is a fire hazard.
Cooler Master isn't well know for their PSU, however, they do have some gems. This is not one of them. If you have the option I would upgrade to a solid 500W. However, yes that PSU will work fine with your build you just don't have much room to grow with it. If you upgrade your graphics card you really don't have much headroom.
Your power supply is the single item you should NEVER cheap on. It powers all your components and if it doesn't have certain power protections it would take out multiple components if it experiences a failure. I'd see this happen first hand a few times and you don't want that. If you are in the US I would recommend the below. The Antec Earthwatt 500W is my go to PSU for entry level builds. Newegg has $15 off right now for the 500 and 650w versions. The 650w also has a $10 MIR which makes them both $55 in the end. The 500w alone is enough to power a system with most video cards.
