Will a 550 watt power supply support this build till I can upgrade?
Asus Rampage II Extreme Motherboard
Intel Core i7 Extreme Edition I7-975 3.33 GHz Processor
Corsair Core i7 Dominator 6GB PC12800 DDR3 RAM
and
VisionTek - ATI Radeon HD 4890 Overclock 1GB GDDR5 PCI Express Graphics Card
or
BFG - NVIDIA GeForce GTX 285 OC 1GB GDDR3 PCI Express Graphics Card?

You're Unlikely to upgrade soon.
And unfortunately that PSU won't handle it even at stock without upgrades :(

My PC just died, it's extremely outdated. My wife's PC is a Core2 Duo, but I find it really slow. I don't want to buy another for another several years. It's either buy the minimum higher end parts to build one off of the one that died or buy a new Velocicty Micro System from Frys.

If my calculations are correct such a system would cost you like $2000+!
So my advice is start a new thread to get recommendations on it as this thread would get ignored due to wrong placement and "non-interesting" title.

New system build seemed appropriate to me, as for cost.
I7 975 = $700 Ebay
Cooling fan for it $40 Ebay
Rampage Extreme = $370 from Newegg
Corsair Core i7 Dominator 6GB PC12800 DDR3 $212 from Newegg

BFG - NVIDIA GeForce GTX 285 OC 1GB GDDR3 PCI Express Graphics Card $269.99 + Tax Bestbuy
or

New! XFX - ATI Radeon HD 4890 1GB DDR $199.99 Bestbuy

The 850 watt PSU I'd have to look into.

Again I recommend to open another thread and we'll be able to cut its cost in half (Hopefully :D  )

I also agree with psycho, but only on one thing, to open a new thread regarding the components and cost. However a 550watt PSU will power that machine with room to spare.

Proof here. http://www.tomshardware.com/reviews/geforce-gtx-275,226... Add ~100watts to account for a CPU under full load. By doing so the GTX285 machine is pulling 357watts (257+100) from the wall. The Computer itself is using less then that from the PSU. On average a decent PSU is about 80% efficient. 357x0.8=285.6 That means the computer itself is only using 285watts, whilst the rest is wasted as heat. Not much eh?

He needs a better PSU for future safety.
If he's NOT going to OC then why the i7 965 (not 975 if he needs!)?!
If he's not planing a top of the line graphics then why the GTX285 without SLI and/or OC'ing?!
He said that he used an EXTREMELY outdated PC before he thought of upgrading and his wife's PC is a C2D seeing it slow doesn't mean he needs an i7 (And EXTREME! :p  )
He absolutely doesn't need a Rampage II Extreme if he's not trying to break the world record! (I need some of its features so it's a different case ;)  )

From what i understand he already has the 550watts PSU from his original build. This is an assumption. It shouldn't have a problem supporting his new build until he get's a new PSU. Although, factoring in capacitor aging and stuff, the older PSU could be running close to maximum capacity. Couldn't hurt to try though.

It might be advantageous to us to know what make and model this 550W PSU really is... (Not all PSU's are equal)

hmm you should save your money and just by a pc in the mid range. you do not need a killer pc for today gaming or programming. anyways, you will need to get a psu of 900watts or more.

well enjoy flushing your money down the drain.


later.

I agree with croc...you need to find out how many amps it has and how old it really is.

You might want to look towards the "sweet spot" of bang for your buck. Bleeding edge is past the point of diminishing returns. I wonder if one would notice the difference between the i7 920 and 975. (save $300) Or the difference between the Asus Rampage II Extreme and the ASRock x58 Extreme. (save $200)

But what do I know, I'm a cheapskate.

a c 248 ) Power supply

I normally don't come over to this section. I usually answer questions in the psu & case mods section of this forum. I decided to have a look because of the title of this thread.

The general rule of thumb is that a high quality 500 to 550 watt power supply with sufficient current (amps) on the 12 volt rail(s) can easily handle an overclocked system with any single video card.

As for the OP's list of components, Lucuis was the only one who gave a reasonably accurate answer. In addition to the Tom's hardware guide, there are other respectable web sites that also test system power consumption. Their results fully support the general rule of thumb.

The only thing left to determine is whether the 550 watt power supply the OP mentioned is a high quality unit and what the OP meant by upgrade.

Why dont you go buy the 920 and save 400 dollars?

Yeah, thats better, then mildly OC it to 3.3GHZ, and bam, you have a less that half of the price i7 975. And if your paying so much for it, why not just get a new PSU? Corsair HX 620, 650 or 750 will do fine, if you dont want modular, get the TX line...
Simple :) 

Cya.

EDIT- Get the ATI 4890, way better value than the GTX 285, or wait for the new 58XX series.
