Will a 700w keep up with my new OC?

post #1 of 14
Thread Starter 
I just recently overclocked my Core i7 920 from stock 2.66GHz to 4.0GHz and my memory up to 1600MHz. Now, my current 850W power supply (here) seems to be handling the load just fine. However, that power supply is not modular, which is bugging the hell out of me. It is a mess inside my case. I'm looking to get a new modular power supply. I'm looking at the OCZ ModXStream Pro 700W (here). Someone who has good knowledge of this stuff has already told me that that power supply will handle the load just fine, but I just want to be sure. Given the recent changes to my system, will that 700W supply do the job? See other system specs below.

*EDIT*
Someone might want to put this in the PSU section. Sorry about that.

A quality 500w PSU could handle your rig with ease. why are you looking into 700 and 850 PSU's?

Unless your going for SLI in the future then a quality 650w PSU is more than enough.

This should be in the PSU section.

Thanks for the quick reply. There is always that potential that I will go SLI in the future and maybe even get more hard drives. I just want to make sure I leave pretty good room for options like that. Good, glad it will work.

you dont NEED modular power supplies, why does everyone rave about them,

only time it's needed is if you're pullin a 1000w with quad sli or something insane

Your 850 watt psu is better than the 700 watt psu you stated.

If you are 100% anal about modular and got money to blow (the TX850 is a good psu, one of the best in its price range so don't know why you are downgrading) You can look at something like these:

http://www.newegg.com/Product/Produc...82E16817139012

http://www.newegg.com/Product/Produc...82E16817194067

http://www.newegg.com/Product/Produc...82E16817553003

but if you want something in the OCZ price range:

http://www.newegg.com/Product/Produc...82E16817207007

its out of stock, but this one you can look around to see if you can find one in stock

650 watts is all you need, even if you want to SLI the GTX 560 Ti one day.

Objectively, going from a Corsair TX850 to an OCZ MXS 700W may be a downgrade. However, as all of you have stated, even the 700W is overkill. So, it won't make a difference except for the fact that my case will be neater inside since it is modular, and as it so happens, I am rather anal about the neatness of my case, and I'm not happy with the way it looks in there. It's also a real headache getting around all those extra wires when I have to get inside it for whatever reason. Thanks for the input, I will be going with the OCZ MXS.

The need for a modular power supply has nothing to do with power requirements. Modular power supplies are very popular because they allow for much cleaner setups (i.e., removing unnecessary cables).

I would go with the Corsair HX6560. The cables on that series are way better than the OCZ ones.
Plus the PSU is still better than the OCZ. I have both HX750 and HX650, just great PSU.
