Phenom x4 965 @ 3.8GHz + Sapphire 7970 OC PSU

Get the highest wattage PSU you can afford. Might as well, the higher the wattage the less it has to work when powering that system. It also makes room for upgrades later on, you could use an 850 watt PSU on your next build provided it still works fine, and as its a corsair PSU, it will.

A 750 w would be more than ample for your system you would be lucky to see it draw 450w at the wall, also have you got a decent cooler on that 965 ? as you should be able to push it to 4.0ghz, also what mobo are you using.

wow,what a terrible avdice.

@OP,as uther said,a quality 750w will do just fine-

I'm downgrading to a 7950 as the 7970 is overkill for 1080p. My old PSU has 4 x 12V rails with 18 amps each, its a 650w Xigmatek model, forget the exact model. Its 2 yrs old, should I chuck it and replace it with a TX 750 or keep on using it?

the xigmatek NRP series is a hit or miss, but im in assumption even though it can be a miss, the total power consumption of the whole thing still wouldn't stress the psu as much


if you plan on a single card build, you can easily get away with a good ~600w psu and have a healthy amount of room if you add more things like HDD's and other pci-e cards outside of a gpu.

should I chuck it and replace it with a TX 750 or keep on using it?

yes chuck it, but replace it with the TX650.

yes chuck it not that great of a PSU.


a 500 - 550 watt will do.

If the Xigmatek model is working ok, it'll be ok. It's a reliable enough model, but obviously the Corsair model is a higher quality component.

These articles both say that the Xigmatek model that you have is just fine. Only upgrade if you want to.

you related to that "get the highest wattage" guy?



nevermind . . . .

I'll chuck it. That Xigmatek was from my first gaming build and even though its been flawless I don't trust a $400 GPU on it. I'll replace it with a Corsair TX 750, which I can certainly reuse if I upgrade later on, taking into account capacitor aging.

Yeah, that Raidmax PSU was given to me as a gift, I would have never bought it if I had been using my own money.  

You've not been listening have you ?

The TX750 is a waist of money even the TX650 is overkill for your system, so get it and save yourself some cash.

thanks for not being offended at me poking you in jest.

granted we are not talking about a flaming brick such as a diablotek, however it would benefit the OP to use most any excuse to upgrade the PSU and keep the xigmatek in the closet for an emergency.

Oh no offense taken  
And it's always time to upgrade in my opinion.

I almost spit tea on my laptop at the flaming brick comment.
