Trifire 7970's...1050w Enough? - Page 2

post #11 of 65
1050w is borderline. I vote that it will absolutely power them, but if you push your system hard enough then you will need some more juice thumb.gif.

anything past 1110 watts is overkill,heck even 1000 is already past what you will be using, unless you plan on quadfire and you want more headroom

Im seeing ~750w from the PSU with the rig in my sig.

That is with 6 harddrives, 12 GT-15 Fans and 2x Laing D5. Gpu's @ ~1.2v

Turn the Gpu's up to 1.3v, 20% Powertune and 1.6v on the cpu and i have seen it max @ 1100w but most of the time ~950w.

All numbers are running 3D Mark 2011.

So i would say that you could do it, but depending on how much other HW you have in there you will probably be limited on the OC.

But after spending 1700$ on the gpu's alone i would sell the 1050w (or keep it) and buy a good 1200w +

cpu will use ~107watts at 4.6ghz (according to my cpu-z and my i7 doing 4.6)
so ~932 MAX, fans+harddrives+mobo aren't much.
If it is the seasonic unit, i think it will be fine.
but then again, if you got the money for it, i think you should go for a 1200 unit as it isnt much of a price difference.
EDIT: I agree with WitchDoctor's recommendations, I would also second the Corsair AX1200 unit. Their Customer support is apparently amazing according to
everyone here.

You should not over look HDD's, fans and other stuff. They do not pull a lot of power individually but when combined there power need can be surprisingly high. HDD's are 10w a pop, the WC pump is 10-20w, I don't know how much the mobo takes by it self but I'm sure its more then just 1 or 2w's. USB peripherals can use up to 3w a pop (usually much less thou). The list goes on with fans 1-2w a pop add to that cold cathodes...

Bottom line all the little stuff can end up needing 40w or even more.

Ok but if I do snag a double wide case, and let's say a 400w PSU, can I just hook up a card and a few fans or other little things and stick with my 1050w? I despise selling these on Ebay, and people in my area don't use craigslist.

You're perfectly fine with the X-1050, ignore the naysayers.. if you're really concerned about it just buy a cheap wattmeter and get your facts straight.. should find something decent for 20$ or so.

I will be heavily overclocking though, and I'd like to be safe. As somebody said earlier, they will draw 825w max, and that leaves a very small amount for the CPU and other things. And can somebody please answer my question about adding a second power supply, this seems like the best option to me right now.

Adding a second PSU is never a good solution.. especially when you don't need it... either way, if you're set on ignoring good advice and going with the panicked mod, get an indy regulated unit or better yet, a unit with DC to DC minor rail conversion, this way you won't have to bother with minor rail loads on the second unit...

Go with a quality 1200w....trust me. 1050w is straight borderline, and with over $1500+ in GPU costs, you don't want to be riding on borderline.

I'd recommend either the Corsair AX1200, or Antec HCP (High Current Pro) 1200. They are at the top of their class and capable of outputting much more than 1200w continuous safely. Go with one of those and call it a day. thumb.gif

Congrats on succefully confusing me thumb.gif. I just listed the PSU on eBay, and I've got some time. If I still have it, I'll try it out. The general consensus is a AX1200, not that I think you're wrong, I'd just like to be safe.
