PSU Dilemma

[ChuckleBrother]

So I am considering my i7 upgrade that I've been putting off for a while but I finally decided on my hardware:

Newegg.ca - CORSAIR Dominator GT 6GB (3 x 2GB) 240-Pin DDR3 SDRAM DDR3 2000 (PC3 16000) Triple Channel Kit Desktop Memory - Desktop Memory
Newegg.ca - Foxconn BloodRage LGA 1366 Intel X58 ATX Intel Motherboard - Intel Motherboards
Newegg.ca - Intel Core i7 920 Nehalem 2.66GHz 4 x 256KB L2 Cache 8MB L3 Cache LGA 1366 130W Quad-Core Processor - Processors - Desktops

I have an (old) 780watt OCZ Modxstream PSU that I've had for the better part of 2 years. I am thinking it's about time to upgrade but I'm not even sure if I NEED to.

My gpu is the 4870x2 and I WILL be overclocking my cpu as high as I can get it stable(hoping at 3.6Ghz minimum). I have absolutely no idea what the power requirements will be for this, I haven't really been following i7 or it's power draw requirements.


If I'm not fine, recommend me a good PSU! I'd prefer modular, and if I can find a 100% modular psu I would vastly prefer that to an evil tangled medusa that must be tamed. Preferred $250-300 as an absolute maximum for the price.

Help!

I cant comment on your PSU but dont buy that CPU from newegg. Save a few bucks and get it from Dell with free shipping.

Huh, hadn't realized that the Dom GT's had hit retail. Thought they were still Corsair-only. And on the board!!!

Personally, with that kind of cash being spent, get a new PSU. Seen way too many threads with those ModX's failing. You don't need a heavy 1kW pSU for it - a 750 will give you all the headroom you need for that processor and card, and you've got lots of good options to choose from. Seriously, if you can afford those memory sticks, you can afford a good PSU to power everything.

I will be perfectly honest:

I cannot afford that ram, I am buying it because

a) it will perform well
b) looks ridiculously sick

What is a good option for a PSU? Are any of the ~800watt Silverstone's good? I need something that is also fairly compact physically(will sacrifice modular design for size).

For the price I am considering this:

NCIX.com - Buy Corsair TX850W 850W CMPSU-850TX 12V 70A 24PIN AT Power Supply Active PFC 140M Fan Powersupply - CMPSU-850TX In Canada.

Fits my requirement for size(I mount my PSU weird), is there any better value out there?

I believe that's the best value for a 850W PSU.

Just make sure you price match to this: Buy CORSAIR [CMPSU-850TX] Corsair TX850W 850W CMPSU-850TX 12V 70A 24PIN AT Power Supply Active PFC 140M Fan Powersupply

I think I will be going with the Corsair, the Ultra looks nice with its full modular cables but...$100 less wins every time:)

You'll be entirely happy with the Corsair PSU. Its a great choice, with exceptional value!

As to your earlier question, yes, pretty much ALL of SilverStone PSU's are excellent, with the Olypmia, Zeus, and Decathlon being, oftentimes, best in class.

How much power would a Phenom II 940 OC'ed build with two 4890's need? 750 watts?

850W from corsair gets my vote, wouldn't touch the Ultra 1000 W psu with a ten foot pole.
