Best PSU for new rig

Hi,


I'm building a new rig with these specs:

i7 3770K 3.5 GHz
Asus Maximus V Formula
Kingston HyperX Genesis 16GB DDR3 1600MHz CL9 Dual Channel Kit XMP
Antec P280
Asus Radeon HD7850 DirectCU II 2GB DDR5 256-bit v2
Noctua NH-D14 CPU fan
2x Western Digital 2TB SATA-III 7200RPM 64MB Caviar Black in RAID 1

I also have 3 other SATA2 HDDs from my old machine, and I'm thinking about purchasing an SSD sometime in the future.

The system is mostly used for storage and moderate gaming. Could you recommend a good PSU that will also be future proof?

I was thinking of something like Cooler Master Silent Pro M700 or Enermax Triathlor FC 700W.

Is 700W overkill - will a cheaper 650/680 PSU suffice?

Thanks.

Any decent 500W unit will be good enough.
Even some 430W units will be plenty.
I don't know why you're aiming for such a high wattage PSU.
Your PC is incredibly efficient.

Still if you want to have enough power for a second card and then overclock , you might need something more.

Thanks for the feedback.

The Seasonic S12II-620 model seems really attractive for its price points. However, since I'll be using my system for storage (will be adding HDDs along the way) I'd prefer something with 8 SATA cables (I'm planning on maxing out the mobo SATA ports.

Could you recommend something with more SATAs around the S12II-620 price point?

Thanks again.

The seasonic has 9 sata connectors.

He probably meant for some day if he wants a mid/high end card, a 400W psu won't cut it for 8 hdds, a high end gfx card(if he wants to) and other stuff, so for just a few dollars more he can get a quality psu with 9 sata power connectors, with 48A on its +12v rail, with two pcie connectors.

That's exactly what I meant. I'll probably upgrade the GPU sometime in the future and use all SATA ports I have available.

So far I've nailed it down between the SeaSonic S12II 620 Bronze 620W and it's modular version (the M12II-620).

I'd generally prefer the modular model because both have a lot of cables and the Antec P280 is a high-middle tower with not so great cable management.

Lastly, I'd like to clear something out. I've seen the M12II-620 speced on some sites as having 24A on +12v. However, the official specs list that it has a combined 48A because of the dual +12v rails - is that correct?

Thanks again for the help.

Yes, it has 48A, you might want to take a look on the capstone 650M, if you want a modular psu, it's a quality modular psu made by super flower, it's at 75$ after mir, it has 8 sata connectors.
