i only need 400 - 430 watts to run my system so i was looking for a 500w psu, i dont want to spend much more than GX

Got a CM GX650W 80+ B...(Not the lite version)
Well, it is said about that the only weakness they got is the 3,3v not stable at one point.

GX is the second version for this model from Cooler Master and tend to be better. Of course those are still average PSU for affordable prices.

Looks quite stable for me as i have some high & low voltage efficiencies issues at home due to some others electronicals not plug on ground in that old country-side house where i'm leaving actually.

GX got also active PFC/PWM combo and the fan suppose to be one of the best (Adda).

GX 650W v2 Review

PS: My Motherboard have a onboard anti-surge protect as the GX has it also in his specs

i use the extreme power calculator and after including everything it always adds up to 400w to 430 w on different configurations

Why not do your own research on what each component uses?

The online calculators vary widely. What does that tell you?

The average hard drive uses 6 or 8 watts.

You can google what a video card uses with accuracy.

RAM power usage also. DVD drives also.

CPUs also.

Calculators typically assume that the owner of a system that actually uses 250 watts under a full load is dumb enough to buy a no-name PSU of 600 watts rather than a good PSU of 400 watts.

The calculator designer must allow for the fact that a dumb-ass might buy a bad 400 watt unit that can only put out 250 on a good day. So they recommend 600, hoping that it will put out an honest 400.

Get the picture?

Calculators designers are quite good to use but those Websites have a little tendency and may not rate the same value for the same configuration you try to apply.

I'll suggest to make two or three of those Websites and try to evaluate yourself with all the results given.

I do things a little more simple.
1. If you are on a tight budget we understand. A power supply isn't the place to skimp on. Everything working in a computer depends on enough of quality power.
2. As far as I'm concerned those power supply calculators are Bull Droppings.
3. Until one is sure of the video card picking a power supply is iffy. Unless you just pick one of high wats and amps, 850W with 65 amp or higher.
4. Their is no such thing as a cheep quality power supply.
5. My preferred brands are Antec, Corsair, Seasonic.
6. Power supplies are like any other component in a computer. You must do your research to decide which ones to buy.
7. I will give guidance and suggestions but I will not do your research homework. I did many,many ours of research just to pick my power supply.
Hope this helps.
