PSU good enough?

December 6, 2009 at 03:15:15
Specs: Windows 7
Will the following psu be good enough for my

thats the psu i plan on getting, will it power the

AMD phenom ii x2 545 or the Athlon x4 620.


Apacer 2gb RAM ddr3 / will get another 2gb

XFX ATI Radeon 4850 512mb ddr3 or XFX 4870

500gb Hard Drive

Now thats all i think, but the motherboard that
i got can run xfire, so if it happens that i might
get another 4850 / 4870, will i need to get a
new psu? or will this one be good enough?

And the last 2 things i want to know, which is
off the topic of the psu, Will the Raidmax
Tornado pc case fit all this in? cause im
looking to get a new case. And is the Radeon
4850 good for modern games? cause i got a
friend which said his one cant even play cod4
moder warfare 2 with out crashing.

thnx in advance, and sorry to ask these
questions, cause i dont now much about psu
and what they can handle so i dont want to
make a mistake.

Hd 4850 can play cod modern warfare 2 maximum settings in 1680x1050.and instead of buying 2 hd 4850 or 2 hd 4870 better buy 1gb hd 5850. Between hd 4850 & hd 4870, hd 4870 is a better card.The psu u select has low efficency 70% multiple rails and i can't find how much amps each 12v rail have.How much did you pay for that psu?

the price difference between 2 hd 4850 / 4870 is much less than
the hd 5850, and on the plus side i will be buying it from my
friend who is selling 1 of each at quarter of the original price.

And i wish i could tell you the price, but im taking it stay in the
US, my currency in Rands. i paid R564, i think its around 80$
but i may be wrong

That PSU is NOT gonna do the' doen't have enough amperage on the +12v rails. One rail is solely for the CPU, the other is for the rest of the system. You're not gonna be able to run 2 x HD4850's with just 16A.

See response 15 & 16 in this thread:

Look for a PSU with a single +12v rail with high amperage....this 650W Corsair w/52A for example:

i got a basic idea now of whats needed thanks to that thread
with response 15 & 16.

Unfortunately as much as i would like to have a Corsair psu (
since everyone thinks it the best when going into quality and
performance) there's only one pc shop close by to me that
sell corsair psu, and because of that its price is a joke, way
to expensive for my liking.

I have access to the following brands:

Premium (price very high)

thats all that is sold at a reasonable price, close by to meso im thinking, what about the following cpu's, will they be
good enough?

thats a Coolermaster one at about 113$, there is 2 makes of these i think, this one linked below if the cheaper of the 2 i think, here's another from another brand

thats a Gigabyte one at about 130$, i think its only sold where i live, since
every sight i go on shows its price only in Rands :P

Which will be better? and which one will work with my pc?

I'm not gonna go to the Proline (never heard of them), Gigabyte or CoolerMaster website & check the specs of every single PSU that they sell. You know what you need to look for...a PSU with a single high amperage +12v rail. If you're not willing to invest in a decent PSU, don't even consider running two cards in crossfire.

ok well i took a look at the gigabyte sight about the 720w psu,
its got 4 rails but i dont know how to figure out its total amps,
how do i now its total amps as there's many places where it
shows A

then the coolermaster one has been certified to handle SLI
systems, to what limits i dont know and at the coolermaster
sight i could not find how many rails it has, and i dont now
how to work the total amperage on it, but here's the link as

Could you also explain how i work out the total amperage of a
psu? cause i was thinking that i should just add all the
numbers which have A next to them.

I feel Cooler Master RS550 is pretty good.

I'm sorry but the Cooler Master RS550 is garbage for using it for gaming. I mean only 16amp on both 12v rails? That's budget psu amp specs there.
