GTX 285 SLI with Corsair 750TX

[Eluros]

Greetings, all,

So, I'd like to know if a Corsair 750TX would be able to power two GTX 285's running in SLI. I've found a bunch of different-- and largely contradictory-- answers online, and am not sure whether this PSU could support it.

My PC is an i7 rig, and has only a single hard drive and two DVD drives-- everything else is standard.

Thanks! If you're claiming from experience, thanks-- please say so. If you're claiming based off figures you've read online, please give me a link for my own future reference.

Much appreciated!

It will probably work. What are your future plans? If it is just to run it like this for a while before near future upgrades or if you don't Fold and just game on occasion, go for it. If you were hoping to get several years out of it and will be stressing your system (gaming/Folding all the time) then you may want to consider saving up for a higher wattage replacement. While good PSUs like the Corsair should be able to handle 100% load, it is stressful on the PSU for long-term use. HardOCP does an 80% "torture test." For longetivity I'd say use it or go higher capacity based on the durations you expect to be stressing your system.

Thanks... this clarifies why I have been finding contradictory information (some said it would work, others said it wouldn't).

I don't plan on any folding, but I do plan on lots of heavy-duty gaming. I already have (and am using) the PSU, and I'm not looking to get another one. I'm getting married in about a year, so this will be my last major PC purchase for awhile... therefore, I want to invest right for the long-term, but need to save as much as possible. I need a decent price-performance, but my funds will be *much* less liquid quite soon, so I'd rather pay an up-front premium for long-term performance.

The PSU has a 5 year warranty, based off my understanding. So, worst case scenario, I can't imagine it'd last longer than 5 years if it was going to die on me...

Would you be comfortable giving me an estimated probability of it working without a problem? Additionally, if you (or anyone else) were to recommend a step down in terms of power requirements but would still offer great performance and high resolutions for a long time, what would it be? a 295? 4870x2? I prefer to stick with EVGA and thus nVidia, but am willing to do what I need to do.

Thanks!

i7 with 285 sli... probably never pulls more than 550 watts. When you do happen to be gaming/whatever you're probably not at 100% system load either, so likely closer to 500w as an average usage while loaded. On a quality 750w unit like that, theres no reason to expect it to fail early, even if its stressed at 500w (actually around 400w DC out of 750) often

285 draws 183w according to wiki. add ~150w for cpu and you are barely over 500w. Add some drives and accessories and I doubt it would ever go over 600w. the 750tx claims it can supply 720w on the 12v rail so it should be plenty sufficient.
btw, buy.com is $10 cheaper than newegg.
