Hi, im getting my new rig in 9 days and i want to ask. I got a 5850HD a 3570K a coolermaster HAF X case some 1600Mhz ram an SSD a 640GB hdd an Arctic cooling freezer 13 pro and i thought a coolermaster 600W pro gold series would be fine. Was i right? I mean 600 doesnt sound enought now that i look at it. I am also going to buy a 7870 or 7850 on christmas will the PSU be enought?

More about : 600w

Easily. You could even crossfire any of those three cards on the SPG 600W.

However I don't really like the SPG series because they all have rather high ripple and noise on the +12V rail. On full load it is just about in spec, so it shouldn't be that much of a problem. I just don't recommend it because I would not buy a unit like that for myself.

so its going to be a lot of noise under stress? Other than that its enough for both an upgrade and the rig as it is?

Yes to all those questions.

More then enough. You might be able to make it work at 500 but why risk it?

dweet thx cos i was kinda worried....btw just a question.. What would happen if i had the same specs but i had a 15000W PSU. What happens with all that unused power

yes a 600w will work
keep in mind you want to loud a psu around 60~75% for best use
so 600~650w will do grate

my last question is if it will allow me to do everything on my rig. I have an ssd and a hdd i want to OC my CPU and my graphics card comes OC'ed from the box im getting a windforce 3X 7870 can i do all those at the same time with my PSU?

The computer only draws how much it needs to from the power supply.
So if your comp needs 435W from the PSU, it will only take 435W from the PSU, the comp isn't forced 'the power'.

Another question... I might go for a 7950.... Its 650W recommended i got a 600 pro gold? Wrong choice huh? cant use a 7950 Oc the cpu use an ssd and a hdd

Oh btw im getting the double D edition from XFX

it also says in the coolermaster webpage that the power output capacity is 600W but the maximum is 720 what does that mean?

Even with that, your computer likely still won't break 500W.

The question is how well your PSU will age after hundreds of hours at that load level.

The SPG 600W is still more than enough for a system with a 7950, and will be so for the life of the PSU.

The SPG units use good quality capacitors (mostly Japanese and most 105C rated, there are some 105C rated Teapo capacitors, which while not as good as good Japanese caps are still very good quality).

I think the 720W figure is how much can be drawn from the SPG 600W before it will shut down to protect itself.

600w will definitely be enough...

last question just to be sure. i did this in the coolermaster site and it said 650 W PSU. i selected my parts. 5 casing fans inc 4 20mm a 7950 an ssd a caviar black sata 2 a dvd RW drive an OC'ed 3570K and 2 sticks of 4GB 1600mhz DDR3 and an arctic cooling freezer 13 pro. hows that for a 600W SPG

At least you're not a few hundred watts out; 50W is nothing to be concerned about.
August 28, 2012 4:47:12 PM

what do you mean concerned.... It will work above its normal output and will be loud cos its fully loaded and its life will be shortened right?

I said to not be concerned.
Cooler Master is recommending a 650W PSU for the system you put into their calculator, they do not mean that the system you inputted will consume 650W.
