Need power supply advice

[gamer3d]

I am currently looking to build my third pc for my bro. These are the specs:
intel i7 2600 3.4ghz
500gb sata2 hdd
intel h61 chipset socket 1155 mobo
4gb 1333ghz ram
HD6950 graphic card


What i want to know is what is the minimum power supply could i have for all these components and what make and model psu should i buy. The power supply must have a 6pin and a 8pin graphic card power connector

For any new build today, get a SATA3 hard drive. If this means you need to change your motherboard and spend a little more money - do it. Completely worth it and will make a big difference once the drive is full with an OS and data.

Anyway.. going from that you will need around 400W-450W.
I'd say get yourself a 500W PSU so you know everything is covered, and if you add another hard drive or something down the line, you're not going to need a new PSU.

Hi, for that build and graphics card I would recommend a Corsair psu, either the 650w or the 750w psu, at least then you have ample power and room for future upgrades.

for instance: http://www.scan.co.uk/products/650w-corsair-hx-series-modular-80-plus-bronze-85-eff-sli-crossfire-eps-12v-120mm-fan

Dont buy a cheap make PSU, I have made this mistake before, I had a 900w psu that was very cheap, it blew up after 3 days and took one of my graphics cards with it!

Cheers

Yes..I agree buy BRANDS ONLY!
And also i would suggest you at least have a 850w psu with u.

 

[gamer3d]

are these good power supplys Corsair GS600 and the Corsair CX600?

 

[ghnader hsmithot]

Yes it looks if you dont want to upgrade to cf so that psu is enough for you

 

[gamer3d]

Some people say i might need a power supply that is around 500watt but some say i might need one as high as 750watt. I am very confused which one should i get?

 

[dhicks19]

Look, Ideally for that system you should get a PSU between 600 - 750w PSU. It really depends on your budget, if you can afford the Corsair 750w then buy that one

A quality 600-650W psu would be fine.
Corsair,XFX,and Antec provide that.
Either unit from Corsair you've mentioned would be fine.

Realistically ? A good quality 430 watt psu could power your components, but the minimum is not what you should be looking for.

Dude are you guys serious!? 650W, 700W and even 850W!? You have no idea..

The minimum that would run this system as delluser1 said is around 450W.
If you buy cheaply the most you'd need is a 550W, branded would need 450W-500W.

Even if OP put a second graphics card they wouldn't need what some of you are suggesting

I am under the impression that the 6950 needs two 6-pin connectors, rather than a 6 and an 8-pin. So, any 500W (or above) PSU with the required connectors that is a quality unit will be enough. The H61 chipset is not designed to support more than one graphics card, so there is no possibility of crossfire.

These links show that power consumption (with more power hungry systems overall than the one gamer3d specified above) barely goes above 300W:

You'd have to be running your system hot, overclocked and under load for extended periods of time to really justify more than 600W. Obviously more than 600W might be a good idea if there are lot of upgrade plans/desires in the future.

And I want not buy a Corsair CX600 for myself because of the comparatively low efficiency, lower internal build quality and lower temperature rating than a lot of units that aren't priced very differently from it.
