View Full Version : PSU overkill?
Why do people have such huggee PSU's?
E8400 @ 4GHZ
ASUS TRITON CPU COOLER
ASUS P5Q-PRO
OCZ 4GB 1000MHZ @ 10057
OCZ 900W MODXTREME PSU
BFG 9800GTX+ OC
SAMSUNG 1TB F1 HDD
SAMSUNG DVD-RW
ANTEC 900 CASE
I saw that in somebodies signature...surely that PC would be A-ok on 500W?
Yeah a decent 500w psu would power that ok i would have thought. Thing is some people like to think ahead, say he upgraded to a 280gtx for example then the 500w psu would probably need replacing too which means the £50 spent on that would have been wasted.
Maybe they are intending to go SLI at some point?
I have a 500w psu, which yes would do his system fine, but if i went to a bigger card, even to a 4870 i would be worried about consumption.
Recommended psu of my gfx card (on the nvidia website), is 300W (minimum), I use 210W absoloutly fine. Soo, I think there is some miss leading going on XD
Think its called covering ones backside ;) If they recommend a 200w psu and you have 6 hdd's or whatever and it didn't work on a 230w psu there maybe some unhappy customers out there.
:chairfall::chairfall: yer ok, very true =]
OCZ 900W MODXTREME PSU?
I wouldn't buy OCZ for sLI's, Crossfire's... or for high ed pc's which need GOOD/Powerful or with 700-1000W PSU
Be Quiet, Enermax, Corsair, Zalman...:thumbsup:
If i were to buy a psu for a top end pc it would be seasonic, silverstone, pcp&c, bascally anything with a BIG SINGLE 12v rail.

Concur +:thumbsup:
how bigs big...mines 12amps xD I'm guessing sumit around 24amps?
try 60 or 70amps :thumbsup:
yeah around 60amp on the 12v rail for a 700ish watt psu is "big"

Mine has 70A on the 12v rail.. :)
And its silverstone so gets the :thumbsup: from me ;).
70A WOW :P thats BIG/overkill ^^ what cards would 9800's should work fine on 24A (thats what i've read anyway)

not if gtx 260's are involved! :chairfall::chairfall::chairfall:
There's a link in the graphics card section showing how much certain graphics cards use at full load.
http://www.tomshardware.com/reviews/geforce-radeon-power,2122.html
From the rest of the data in that post, the system below draws at most 610 watts (with Dual GTX260's)
Now, that's a high draw CPU (65nm C2Extreme @ 3ghz)... running two GTX260s.
430watts whole system draw with a 4870 x2! FULL LOAD!
Going off that, I'd say a 600watt supply would be enough for just about any rig. Even if we allow for another two hard drives at 20W each (generous) and doubling the RAM, I cant' see actual draw being over 500W. Allowing another 100W for power fluctuations and I really think there's no need for a bigger supply. Maybe if you're running a heavily overclocked, watercooled 2x 4870X2 system with a stack of VelociRaptors in, you might need more. But I'd say 500W will be fine for most systems based on this.

And its silverstone so gets the :thumbsup: from me ;).
Anyone guess who I bought it from? :lol:
wild shot in the dark here...but was it mac :lol:
:lol:
Unsurprisingly, yeah.. ;) :lol:
Lol well i did seem to have an abundance of psu's at the time, iirc i had a 1kw Antec kicking around at the time too.
Well, it worked well all round.. :)
