post #1 of 13
Thread Starter 
Hi, I have a corsair gs800 psu that is new. I have a fx8120 clocked at 4.6 at 1.44 and a hd7870 with a factory oc and a little bit more. I want to buy another hd7870 to xfire. would my psu be ok? lot of innacurate power draw info on the web and rather seek the knowledge on this forum. thanks in advance

those psu apps ar a bit lossely configured at best and there are some pretty bad horror stories relating to fx power draw when overclocked so just wondered if I may have to plug into the national grid.

plenty

Although I would not run xfire on an amd cpu.

can see where this discussion would lead ha. I read all the info about bottlenecks regards single higher end gpu with my chip and decided to take the gamble with the 7870. no bottleneck in any game, 100% useage. will another bottleneck just because of some widely reported benches from variable sites. I cant say because not seen any benches to prove it by owners so I will let you know when I find out. I put my neck on the line and say there will be no bottleneck. Bit off topic but thanks for the input anyway ha....... to be continued in another thread

Ha fine I have not looked at the level of gpu. Personally I came from a 1090T and HD6950s xfire to an i52500k. Difference was day and night.

Anyway, your PSU be grand, good luck with the build thumb.gif

Thanks for the input. was just real worried having seen some synthetic power draw charts. I think my gpu uses 175w at max x that by two and was worried about the headroom with my cpu overclock

To give you an idea... I would feel comfortable crossfiring 7870's on my HX650, granted my 2500K sips power compared to an 8120 @ 4.6.

Yeah, two 7870s really don't draw too much power. You can CF with a 650W no problems. Also, with a cpu overclock
