Whats the wattage this PC needs?

post #1 of 17
Thread Starter 
Hi,

I would like to know how many watts does my power supply gonna need to have in order to sustain this pc:


Intel Core i5-3330
Corsair Vengeance Red 8GB (2x4GB) DDR3 2133 MHz (PC3 17000)
XFX ATI R7850 CORE EDITION 1GB DDR5
GIGABYTE GA-Z77X-UD3H
2 TB HARD DRIVE



Is 750watts enough for this setup?.. Please advice which would be the best wattage to aim for.

thanks.

All that's needed is a quality-made 400W power supply - and that's not the minimum either.

Ummmm 650W would be overkill for that... biggrin.gif
post #4 of 17

I'd like to qualify my information before it's too late:

 

http://www.guru3d.com/articles_pages/amd_radeon_hd_7850_and_7870_review,7.html

 

With one 7850 under full load in their system, their PSU pulled 256W from the wall outlet.  Their CPU was idling, so I have to add 77W for the i5-3330.  Adding 77W makes the PSU pulling 333W from the wall outlet.  So if the PSU is 85% efficient while pulling 333W from the wall outlet, then that means the system is only pulling 283W from the PSU.  Your actual gaming load will be closer to about 225-250W.

 

The only reason I recommended a quality-made 400W PSU is due to what's commonly available on the market.  In other words, it's going to be significantly easier to get a quality-made 400W power supply for your system than a 300-350W unit.

wow... this really surprises me..
for my old q6700 ati4890 i needed 500-600w and for this new pc 400 its enough? I thought the power consumption would always be higher for a new pc compared to a 4 years old pc but i guess im wrong. Is this pc considered somewhat good? Is it gonna run every new game for a couple of years?.. I know its not the best pc i could buy but in my country a pc like this cost 1000 bucks so its kind of the maximum i can spend on a pc..

Thanks for all the answers, and sorry for my bad english!

what's your budget and what country are you in?

there's a couple of things "wrong" with that setup...if you are interested in overclocking, then you need to get a K processor - if you are not interested in overclocking, then you don't need a Z77 motherboard; a B75 or H77 would be better suited.

i can put together a list if you gimmie a budget....and as others have said, you'd be fine with a ~400w psu.
be quiet!

Each new generation of CPUs and GPUs requires less power than the previous.  ;)

 

Anyway, I don't know one way or the other how your build rates.  I'm too far behind with that stuff.

Agreed with this. Also the RAM? No noticeable improvement over 1600MHz.

All of these things considered means more budget for GPU or SSD, either of which would be a noticeable upgrade.

If you could do that it would be great ! smile.gif
I live in Uruguay, and my budget is 1000-1400 USD.
Here is the webpage from the company im buying the parts and building the pc myself.

You can see the prices in USD in that page, and its translated using google translator.
the budget must include a good quality "computer case " ( i dont know if thats how its called, hopefully you will understand what that means)
Thanks in advantage.

First off, that's a huge variance in budget, certainly $1400 will buy you a better rig than $1000.

Do you want to overclock the CPU?

http://www.banifox.com/Gabinetes/Cooler-Master-Haf-912/flypage_images.tpl.html U $ S 98

http://www.banifox.com/INTEL-CPU/Intel-i5-3570K-Core-3.40GHz/flypage.tpl.html U $ S 334

http://www.banifox.com/DDR-3/8GB-kit-4GBx2-DDR3-1866-MT/s/flypage.tpl.html $78

http://www.banifox.com/Socket-1155-Intel/Asus-P8Z77-M/flypage.tpl.html U $ S 190

http://www.banifox.com/Solidos/Sandisk-Extreme-SDSSDX-120G-G25/flypage.tpl.html U $ S 190

http://www.banifox.com/Fuentes/Fuente-Antec-HCG-520/flypage.tpl.html U $ S 118

http://www.banifox.com/ATI/Radeon-HD-7870-GHz-Edition-2GB-256-bit-GDDR5/flypage.tpl.html U $ S 401

Total $1409

You could spend less on a motherboard and swap the SSD for a mechanical drive if you wanted. But this will give you a good idea of the top performance for your $1400 budget.

or there is AMD

http://www.banifox.com/AMD-CPU/AMD-FX-8320/flypage.tpl.html $257
http://www.banifox.com/Socket-AM3/Asus-M5A97/flypage.tpl.html $156

saves $111

The pricing of some things are crazy tongue.gif
