Need Help and advice on choosing the right PSU

post #1 of 8
Thread Starter 
So over the upcoming school holidays I have talked to Billy's mum about the computer build.
This is what we're looking at so far which is relatively the same as mine except for the case and the CPU is the i5.



My question is what Power Supply will suit us best for our build so far. Later on we will add a GPU seeing as the GPU exceeds the $1,000 limit....its not a urgent requirement.
Hopefully the onbaord graphics will run GTA SA SAMP "decently".

Sometime later we might add either a: 2TB WD Green Harddrive for storage (like my setup) or just get a 1TB portable. He will only have a 100GB harddrive that we are re-using from his current acer computer.

NOTE: THIS WAS IN ANOTHER THREAD only to keep those people interested in my friends build to assist us along the way but I haven't gotten a response yet so copied and posted it here.

Hello
An i5 3570k plus a gtx 680 at full charge require some 350W.
That said you might want to overclock the i5 and add another graphics card but even then it wont double the power draw. You'll be fine with a 700W.
And don't bother picking the unit because of its shinny silver/gold/platinum certification : As it comes with such a huge price raise that you won't be saving money on your elecricity bill for years.

Anything around a 450w PSU should be enough smile.gif Computer hardware today are very much energy efficient compared to hardware a few years ago. Just use this setup as an example from Utopia Computers:

http://www.vortez.net/articles_pages/utopia_computers_pandora_review,1.html

It has an i7-3770k + GTX TItan setup yet it only uses a SilverStone 450w power supply. Quite shocking at first but when you crunch the numbers, 450w is enough for the entire build. I remember the days of the AMD Phenoms and LGA 775 quad-core processors, you would need at least a 650 watt PSU for a typical build with a respectable graphics card. Anyway! just use that as your benchmark in selecting the right power supply. thumb.gif

max 550 watts for a single card system no reason to go over thats overkill

Think you sould look for a 500 watts unit if you can find any and want to spend moey on having a little extra

Yeah I know.
I gave you that number because it was the only one I'm sure of and because it gives a good idea on the power consumption of those components. A 660ti requires less so it's alright.

He said he planned to add on in the future so I figured it would be cool not to have to buy a second psu when it happens.

Also you want to aim at a power draw that is 75% of your total available to keep your psu cool and thus silent smile.gif

Ahhhh all good buddy thumb.gif

And yes silent is a nice feature of any Rig.
My rig has:
GTX660TI gigabyte sc
Kingston hyper x 120gb SSD for operation system and programs
2TB WD GREEN for storage
Intel 17 3770k with normal fan
Thermaltake overseer case - 3 fans
some gigabyte z77-udh5???? cant remember exactly
LG dvdv drive
and Kingston 8gb 16000mhz ram

and a thermaltake 800 watt PSU. It runs quite, but I can still hear. And the Case fans a 3-pin and the Motherboard only accepts 4-pin so they're just spinning........

well some PSUs completely deactivate fans if the temps are ok, find one that does. About your case fans, some motherboards can switch the fan control from PWM (4 pins) to Voltage (3 pins) in that case you'll be able to manage them. If not, you can get fan cable that reduces the voltage (often time from 12V to 7V) so they spin slower and make less noise. And you can always get a fan controler if you want to add more fans and keep control.

cheers
