Default 700W PSU for new build?

Hi there.
Iím about to put together a new build and am wondering whether my current PSU, a 700W Cooler Master Silent Pro M, will suffice to power the system. The components are as follows:
i7 870 CPU with a dual fan CM Hyper212+ cooler
Nvidia GTX 470 GPU
Asus Maximus III Extreme motherboard
4Gb GSkill Ripjaws 1333MHz CL7 RAM
1 WD 300gb hard disk drive
1 WD 500gb hard disk drive (for archives)
1 WD 160gb external hard drive (for work-related files)
1 DVD-CD RW drive
Cooler Master 690 case with five 120mm fans
The PSU is about six months old. It is SLI-ready and works fine with my current system. I had planned to buy a new PSU, but am now keen on cutting my spending a little, if at all possible.
Thanks for your help.

Your PSU will be fine :) any 700W should do fine with that setup, you'll even have some headroom.

What's your budget?

The psu will do fine if your just going for a single card setup, but if you want an SLI setup, your better off getting a new psu like the Corsair HX or AX 750 units for 4x PCI-E 8pin connectors.

I would also change the CM hyper 212+ to the V6GT as its a newer and better cooler than the former.

Everything else is fine, good luck with your build

he won't need to upgrade anything at all :o heck I've seen a review on a triple GTX 480 Setup with a Enermax Rev85+ 850W .. I believe it was TechPowerUp. If that's a quality PSU he might even be able to pull of SLI on his current PSU. That way he won't need to spend more money on his rig.

xlilmissmjx, thats a whole bunch of terrible advice.
You could SLI 470s with a 700W PSU - stop being a fanboy of Corsair, there are other good PSU makers other than the one company.
A Hyper 212+ with dual fans is perfectly fine for overclocks 3.6-3.8Ghz.. anything past that you would need watercooling anyways.

You will be ok for 2+ years I would think. (I think capacitor degradation/aging may start becoming a factor then)

If you choose to SLI you SHOULD be fine too. You could do SLI 470 and be ok.

I was only pointing out the difference between the number of connectors on his unit verses Corsair. It only comes with 2x PCI-E 6+2 connectors verses Corsair's 4x 8pin connectors. I know I'd personally rather get a unit that has all the connectors rather then get one that doesn't and have to get converter cables for it.

I'm allowed to be a "fanboy" if I so chose, it's called brand loyalty and there are plenty of other members here that feel the same way as I've seen quite a few who will only recommend certain ones and to stay away from others.

As for the hyper 212+, its a great cooler with dual fans, I just like V6GT better due to the performance of the 2 stock fans it comes with verses the 1 stock for the hyper 212+.

yeah, im in a bad mood today. I really shouldn't be.. it's Friday!

Anywho, the reason I jumped on the post was he only has one vid card.. recommending a new PSU seems illogical to me. It's an 80+, single rail, modular PSU. More than overkill for his current needs. If you upgrade to an SLI system in the future, be sure to budget for a new (actual SLI ready) PSU.

I also don't see the need to jump to a $60 HSF from a $22, when most 'normal' overclocks would be fine.. especially when he's looking to cut spending. :)

Like every one say, 700W would work just like a charm. I have not a good trust in CM PSU unit but your complete system will draw less than 400W so you have plentyyyy of room to play with.
