I was wondering what the best Power would be to easily support such a build. First, I should say that this is an entirely new build and that money is not a consideration. I also like my PSU's to be a bit overkill - I like a bit of headroom and don't want them anywhere near 100% usage.

My other question would be Modular or Single-Rail non-modular?

Components will be:

Case-------Cooler Master HAF X
Mobo-------Gigabyte GA-X58A-UD9
CPU---------Intel Core i7 980X Extreme
RAM---------Gskill PC12800 PI 12Gb DDR3 (6x2Gb) - F3-12800CL7T2-12GBPI (not sure yet)
Graphics---2x Gigabyte GeForce GTX480 1536MB GDDR5 with after-market air-cooling (GELID Solutions???). Possible use of a third card later on (new Fermi's coming in September-475/485????)

Other stuff:
- 2x Blue-Ray Recorders Plextor PX-B940SA Black
- 2x Western Digital RE4 2TB SATA 7200rpm 64MB
- An exhaust 3 fan radiator on top of the case, and a couple of other fans.

What PSU would you recommend for this stuff, and some other that I can't remember now?

Almost forgot: 3X Monitors (30" +). Don't know what I can find yet, I would like them to be same make/model and S-IPS...

Suggestions would be appreciated, specially concerning availability.

I just got Enermax Revolutions 1250w for a similar setup after reading lots of reviews.

Modular or non-modular?

Does the Bronze, Silver and Gold rating mean anything, or do some companies just not care (like Silverstone)?

Thanks for the replies.

the bronze, silver, and gold ratings are part of 80+, they tell you the efficiency range it falls into. More efficient units generate less heat so their fan can run less.

I agree with Obsidian in that the AX1200 would be a great fit for a build of that level once it comes out, but since its not out yet the strider 1500 and antec TPQ-1200 are the only other high quality ones i know of that will have sufficient power to support 3 GTX 480s, a 980X, and a water cooling setup

+1 for the Corsair AX 1200.. If you are somewhat skeptical on a full modular design, the Antec TPQ 1200 is worthy to consider..

Thats going to be wayy more than you need, and since its a SUN PSU its likely not compatible with an ATX system. The E10K appears to be a large server tower so its probably a redundant power supply and therefore wont fit in the space of a standard PS/2 PSU.

Thanks guys.
AX 1200 sounds like the best bet, unfortunately I would have to wait 2 or 3 weeks for them (in Portuguese time that would be about 2/3 months, or never...)

Managed to get my on an Antec TPQ 1200 (for only 155 Euros/$205USD) so I bought it.

Again, thanks so much for the feedback.

P.S. - Now to find those monitors...
