Need PSU advice

post #1 of 14
Thread Starter 
I'm working on a new system where I plan on running 2 OC'd 560 ti's. And an OC'd CPU. According to most PSU calculators, my setup will need 600~630w. So the question is, should I be going with my original choice of a 650w, or should I be upgrading to a 750w or even 850w?

On top of that, I have little experience w/ PSU's, and could use some advice in choosing one, the FAQ lists a lot of good options, and I was hoping for some more specific recommendations? I think I want to go w/ a modular one.

Thanks for any help!

I myself planned on running 2 overclocked GTX 570s, plus I decided that if I was going to buy a reliable Seasonic PSU, I may as well buy one that will be able power almost any 2 card setup and opted for an 850W. I'd suggest a 750W for you though if you want even more headroom for potential future builds then you can always go for an 850W like I did. It depends on how many upgrades you want your PSU to be good for.

Do you have a budget in mind? I would recommend going for a 650W, as that is typically rated power and not peak power (usually peak power tends to be 100W higher) and you won't be using peak power much (if ever) unless your doing lots of F@H. I would look through the list of recommended PSU's and chose one that suits your needs, budget, and is modular (though you are paying a premium for modular).

650 to 700 would be fine as most good PSU's will be more than ample. Depending of course whether or not you planning on upgrading anything else that could cause more of a draw i.e. water cooling, fans, lighting, overvolting your GPU's.

I would suggest ta couple below:

http://www.newegg.com/Product/Product.aspx?Item=N82E16817151088 - $130

http://www.newegg.com/Product/Product.aspx?Item=N82E16817341018 - $90

http://www.newegg.com/Product/Product.aspx?Item=N82E16817371049 - $100


and furthermore. Decide of you want modular or not as well. Around 100 and 700-750w there is a multitude of good choices.

My budget is fairly open ended. I don't want to break the bank on a PSU, but I do want to make sure I am getting one of superb quality and reliability. Essentially, I am completely unwilling to skimp on a PSU, so the price really doesn't matter as long as its not crazy. To put an actual number on it, I'd say anything >~$150.

Here's the Corsair TX750 V2: http://www.newegg.com/Product/Product.aspx?Item=N82E16817139021&Tpk=corsair%20750%20tx

Here's the modular version if you prefer: http://www.newegg.com/Product/Product.aspx?Item=N82E16817139030

Corsair make some of the best power supplies around (also memory, water cooling loops, cases, yadda, yadda) though I suggest also taking a look at the Seasonic PSUs too.

Seasonic, Corsair, and any Antec High Current power supplies would fit the bill for what you're looking for. As for wattage I would say 700-750watt, but I'm probably off by 50 or so watts. Also good job on not skimping out on your power supply. I made that fatal mistake once, and never plan on doing it again.

Looking atm at the Corsair tx750M and the ax750. The ax is clearly a bit more expensive, but it's something I can afford. So is the Gold rating worth the price bump? I hear a lot of good things about the AX.

The AX has a higher efficiency, is fully modular, and has a slightly higher max output on the 12V rails (basically where most of your juice is needed). If you think the price gap is worth it then it's up to you.

It's all about peace of mind. People love the Corsair power supplies here but to be honest a good Antec High current or Seasonic (both of which can be had cheaper) will more than suffice and go far beyond that. Sometimes it depends on a theme you have for your build i.e. color or lights as well.
