¿how many watts does my computer need?

[shakuganTV]

i was thinking to buy this:
CASE: cooler master storm enforcer
Power supply: cooler master 750 W(it is good enought? or i need more power)
Processor: AMD FX 8150 Black edition
Ram: crosshair vengeance 4x4(16GB) 1.6 GHZ
Motherboard: Asus formula V of republic of gamers
GPU: 2 X EVGA GTX 570 superclocked
H100 cooler for the processor
seagate 2TB 7200RPM sata 6 GB/S

so, 750 watts are good enough or i need more?

if i use only 1 GPU how much i will need? and also if i use 2?


thanks

you wont need more than 750 watts .

Check out the Radeon 7xxx graphics cards instead of the GTX 570

What cooler master 750 W unit are you thinking of getting? I would stay clear of the GX, there were some critical design flaws in them which make them really bad units but they still get sold for the same price as the good units.


If its a good 750 W unit, it can power 2 GTX 570s in SLI without an issue. If you only use one a good 500W unit can power the system.

Get a 3570k or a 2500k if you haven't bought that 8150 yet. It will perform better and use less power.

750 W is plenty for two GTX 570s, but im a bit more concerned about the quality of the PSU, i haven't seen reviews for the Enhance built GX series like that one is but the Seventeam built units had problems once they were over 50% load. Where are you buying from? Im sure there is a better option.
