Coolmaster 500W GX Lite PSU or XFX 450W Core Edition Pro PSU

[Pedroc1999]

Which one of these PSUs should i get, i know the XFX is good quality but i would like a bit more headroom for future upgrades so should i choose the GX

 

[ignatzatsonic]

Do you have any evidence the Coolermaster has more headrooom?

It's made by Seventeam, not high on my list.

Forget both and get Corsair psu.

The only advice that comes to mind for me is, to up your wattage for your psu to at least a 750 watt. I would also consider a fully modular psu. This will ensure you will have enough power for future add ons and upgrades.

what about this one, i done the math (12v x 45a) and it gives out 540 watts on its double 12v lines

OCZ 500W CoreXStream PSU | Ebuyer.com

also i done the other ones and the it added to under 410 on XFX and under 450 on cooler master

i am one a budget so i was sujested the xfx by ignatzatsonic but as i have changed my build a need a bit more headroom

The GX you mentioned is a single rail psu, so why would you want a dual rail ocz one? If you dont want corsair, get the Coolermaster gx 650, its great value for money, but like bassfisher said, rather try to go for the 750.

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

OCZ is average at best. They don't make anything. They use PSU manufacturers like Channel Well, Impervio, and FSP.

Not on my list.

If you have some good but as yet unexplained reason to believe the XFX 450 does not have enough power, get a higher wattage unit from:

XFX
Seasonic
Antec, certain models
Corsair, certain models

You are hampered by your budget.

You are better off with the XFX 450 than a random 600 watt unit built by who knows who.

As with all your other posts, you are better off not worrying about this stuff until you are a month away from buying---which will be next year some time, according to you.

Why do you think you need 400 to 430 watts to run "your system"---whatever that may be?

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

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

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.
