Power Supply Compatibility HX850W

post #1 of 17
Thread Starter 
Aside being fairly new to building computers, I'm taking a bit of a leap and jumping into the seat of building a gaming machine that should meet my personal gaming requirements. This is my first build from scratch.

I'm unsure if the following three products will be compatible with each other, it's the Power Supply that's my main concern.

From what I've read an 850W PSU (In this case HX850W) is more than though to power a machine matching the description below, but compatibility is an issue I'm unsure how to come to a conclusion on.

I've already got myself the computer case, but this is my shopping list for the time being. I would just like some confirmation that the build would be appropriate to start building a machine with i7-960/970, 6-12GB Ram (Corsair Dominator?), 1TB HDD SATA and 2-way Crossfire Graphics)

Shopping List:

Antec Twelve Hundred V3 £137.26
ASUS Rampage III Extreme £245.00
Corsair Professional HX850W £99.00

whats your budget for your rig, that 850 is a solid psu but depending on gpu setup and oc id say a 1000w would be better.
what store you looking at to buy from

Well... yes, it's compatible, but you only need a 850W PSU with the most power hungry video cards out there.

I also strongly recommend against going with an LGA1366 build with LGA1155 out and beating almost every LGA1366 CPU in almost every most benchmarks.

I also also strongly recommend against Corsair Dominator. The prices on those are a bad joke.

Figure out what video card you want and go from there, the decision on a PSU hinges mainly on your choice of video card.

What are you trying to figure out with "compatibility"? Are you wondering if it will fit in your case? If it will power on your system? 850w should be more than enough power for most people, and the HX850 would certainly work with your parts

As for the above poster, there's really hardly any reason that you would go for a 1kw PSU unless you have something similar to my sig. rig or above

1000 watt would be extreme overkill unless he was going with a dual/tri 580 setup.

the 850 will be more than enough for anything you're planning on doing with your new build. The only concern I would have is that the 1200 is a pretty large case, and you might have some cable management nightmares if you don't opt for some extensions.

Everything you listed is 'compatible' but as others have said, if this is a new build, I might consider some other (newer) parts.

Thanks for the very quick feedback guys!
I am looking for LGA1366 in terms of CPU, I will probably be clocking it to between 3.3-3.6ghz.

I've not set out on what graphics I'm looking for just yet, but I am looking to run 2-way Crossfire and will possibly looking to run 3-way in the future. Any suggestions on that too would be very much appreciated. :-)

If you're looking at overclocking an LGA1366 to 3.3-3.6, that tells me that you're looking at the lower-end LGA1366, e.g. Core i7 930 or 950. Those are systematically outperformed by the newer Core i5 2500K and i7 2600K. Is there a reason you wish to stick with the dying X58 platform?

I was considering buying the i7-960 or i7-970. I haven't yet looked deeply into this but I wouldn't need any more than 3.5Ghz clock speed.
