Reading A PSU

[xtpacygax]

Hi,

I am going to get this Enermax PSU:

If you could look at the pictures, the second to last one, the one with the back of the PSU with all the power values. Can someone explain some of those values to me, as I do not understand what any of that means and I would wish to learn the meaning of those values.

Thanks,
Ted

All you need to pay attention to is the 12V rail and the total wattage. In this case there are 2 adding up to a total of 44Amps which is very nice. And the wattage is up to 620 which is very good aswell. You basically want to buy a power supply with 450 and above watts and around 25Amps and above.

Oh, I see. Also why is the wattage split up into different parts? Like there is 597.8 W under part of the values and 22.2 W under other values, adding up to 620 W all together.

Also I was wondering what active and passive PFC is. I think it is something that changes the incoming electricity to the right level or something so the computer doesn't get damaged, not exactly sure though.

amps x volts = watts

20 amps x 10 volts = 200watts.

It shows how much power each rail can do and then adds them up.

I have a recommendation. Its the OCZ GameXstream. Its got 4 +12V rails at 18A each (72Amps total). You can get a 600W or 700W and their around the same price as that Enermax. OCZ is a quality brand like Enermax too so you can trust them.

700W: http://www.newegg.com/Product/Product.asp?Item=N82E16817341002

i have the 600W and its awsome. like the corruptin advertisement of McDonalds says "I'm Lovin it"
O yea, they also have blue LEDs too if you like those

Those are cool PSUs, I think I am going to get that 700 W one. All excellent reviews. I can't believe I didn't see those. I know it says it has SLI support but how come it doesn't have the SLI logo thing?

 

[meefle]

Idk but it diffenantly does have enough power for SLI/CF. That might also hold you over if/when we ever see quad SLI/CF support, stuff like that.

The one thing I dont like about the PSU is that it isn't modular. How do you deal with all of the cables? I really want this PSU but I don't want to deal with a crap load of cables.

 

[meefle]

i put the all unused cables behind my mobo rack.

I hope I can do that with my case and motherboard.
