PSU gurus...I need you help.

post #1 of 14
Thread Starter 
Hey guys I am looking to upgrade from this crap PSU i currently have, but i am not gonna pose and talk as if i know alot about the PSU other than the basics (watts amps rails) that sort of thing.

So the new psu will power my current sig rig the only upgrade to that rig maybe a new graphics card, i was thinking about a pretty high end card, maybe a 580 or the new gtx 460 2win or possibly the 6990. I have asked around and some people say a 700w unit will be enough...others say a good 850 unit will do the job.

I was thinking more along the lines of 800+ cause i saw the specs on the 460 2win and it was pretty steep, 700w psu with 46amps on the 12v rail. Keep in mind i would like to have some extra juice just incase i decide to crossfire or sli down the road.

My budget is around $150 give or take $20 or 30. But i was looking at these units so far and i saw that they got good reviews from HardOCP:

1) Silverstone OP1000
2) Corsair HX, TX and AX series
3) Kingwin Laser gold

What do you guys think...and i am leaning more toward a modular unit...all of the extra cables really are a hassle.

You can't SLI the GTX 460 2Win. It's already two GTX 460s on one card, and you can only connect up to two GTX 460s together, so you can forget about the SLI idea since two GTX 460 2Win would mean 4 GTX 460s together. Not happening.
650W is generally the recommendation for a system with two 460s, so that's what I'd recommend in this instance.

Corsair TX750 v2, Seasonic X-750/760, Antec HCP 750W, XFX CE 750W are some of the better PSUs for the price.

To be honest, whenever I get a new PSU I check out this site just to back up my ideas of what I will be needing. Granted, this site is not 100% accurate and I always give myself 25% or so headroom for future builds or any issues that might arise. For just general purpose things like this, this site works great...at least in my experience.

Keep in mind that most GPU manufactures tell you that you will need much more power than is actually required to run the card because they dont know what other components will be in the case with their card and want to be safe just in case someone wrecks their system...its a liability thing.

For your system you wont need more than 750W, even with a large GPU (unless you have multiple large GPUs, thats a different story.)

Im sure someone will jump in here and give you better numbers than I can (Phead...however you spell his name, you all know who I am talking about.)

A card like the 6990 calls for a 750W or greater, so an 850 would be perfect (unless you crossfire them then you'll need 1000W or more). The 850 gives you a little wiggle room for OCing components, adding them, etc. My personal recommendation would be the Corsair HX 850 if you want modular. Has a mail in rebate right now also http://www.newegg.com/Product/Produc...orsair%20hx850

The Silverstone or Kingwin are both good options for 1000W in that price range, another one to consider would be this Antec http://www.newegg.com/Product/Produc...82E16817371036

It isnt one of their newer units, but it is still a great unit. It is just overkill for your system, but hey, if the shoe fits.
