post #1 of 54
Thread Starter 
Good day ...


I am just wondering how good this PSU is ...

My rig is listed but I will be upgrading to a i5 760 (will definately be overclocking) and I am wanting 2 upgrade my GFX card to the GTX 580

I have never used ati but I am not against them so if ati is better than the GTX 580 please let me know ...


All information would be greatly appreciated ...

Kind Regards.

A TX650 will handle one GTX 580 easily.

As for the graphics choice, if it were me I would get two 6950's and unlock them to 6970's. They would destroy one GTX 580 and the prices are *quite* close.

The TX650 is a good quality and well built PSU. I've got one powering my rig right now, handling a 6950 with absolute ease.

I would always recommend a Corsair unit to anybody looking to buy a PSU.

Please excuse my ignorance ... but what do u mean unlock them ?? ...


And will the TX650W run 2x 6950's and the rest of the system (overclocked cpu)

Now I am stuck with the problem of Only running 1 High end card and not sli ... but seriously ... would anyone ever really need 2x GTX 580's ... it just sounds like extreme overkill

Having to "only run 1 high end card, and not sli" isn't a problem, it's a benefit. I'd consider my system inferior to someone running 1 580, even though I've yet to have problems normally associated with multi-gpu setups.

It should be fine, using the Extreme PSU calculator, it calculates that such a system would utilise roughly 452w, with a 500w+ PSU recommended. The TX650 will handle that fine for years.

As for unlocking the 6950's, there's a good chance that in reference cards you will be able to flash the BIOS to a 6970 version and unlock shaders and reach the performance of a 6970. Nice free performance upgrade there thumb.gif

PSU calculators are inaccurate and shouldn't be used.

You can unlock the shaders on a 6950 (must be the 2GB version) to run at 6970 speeds by flashing the BIOS. It's almost impossible to bork your card doing this as tese cards have a backup BIOS. And yes, a TX650 will handle two 6950's.

Edit: Even if you don't end up unlocking.... two 6950's > GTX 580

Well, I can see you're going to have a problem with everything I'm going to say however the calculator was just used to gauge the approximate usage we can expect from the OP's hardware.

Corsair deliver quality units and I'm yet to have a problem with any of them myself after years of usage, so if I wish to recommend them then I am free to do so. It's called an opinion, you don't have to like it but everyone is entitled to one.

Why would you say that your system is "inferior" ... as long as the sli config is holds greater performance than the single card ... that makes the sli system greater ... or am I missing something obvious ... confused.gif

Well that makes perfect sense ... I just never figured it was possible 2 do this ... are all cards that are based on the same architecture the same ??

Ok ... So if Corsair is the band wagon ... what do you use ?? ...
