the new 750 power supply

Recommended Posts

I cant seem to get a reply anywhere, even emailed Cooler Master on this, and my video card manufacturer, but I recently through Newegg purchased a new system, including the new 750 Watt pro power supply. Will this be adaquate voltage for a sli setup of to 8800GTX video cards, and all the normal additions, such as 4 gb ram, 3 sata drives, X-Fi audio card, Asus Striker Extreme Mobo? Reviews on the power supply are positive, but when I look at Nvidia's website it only lists the 850 as adaquate, and I wasnt sure if that was due to the fact that the 750 is a new model. Any help would be greatly appreciated.

BTW, love the new Stacker Case. It arrived a day before my other components and it is Begging me to finish itself tonight.

The Real Power Pro 750 will power up one 8800 video card, but not two. Each video card requires 2xPCI-E connectors and this power supply on has 2.

It should be enough, don't know if the cables are all the same thow.

here's a calculator if you want: http://www.extreme.outervision.com/PSUEngine be sure to take more than it says, cause thats more like the minimum, 750W should be good I think.

EDIT: ts_123 got faster then me...and as you see, there is the cable problem.

Well, it is SLI capable, but only with cards requiring only 1x6pin connector, which gives 2 in SLI. 8800GTX needs 2, so 4 in total for SLI.

The real power 850 serie and above have 4x 6pin cables.

on a review i just got thru reading it has 2 x 6 pin pci-e and 2 x 8 pin pci-e plugs . this psu i believe will power twin 2900's easily enough as it falls under ATI's quidlines for crossfire 750 watt psu , 4 x 6 pin plugs ( 2 x 4 pin + 2 x 8 pin recommended ) . i do know cm power supplies are good and not a elcheapo i do believe it can power a couple of gtx's if you can convert the 2 8 pin pci-e's to a couple of 6 pin pci-e's ...

Well, it does has 8pin connectors, but they're on the same cable as the 6pin connector ( image ) so I don't know if you'll have enough power for both connectors when using at the same time.

Two 8-pin PCI-Express connectors and two 6-pin PCI-Express connectors. These are spread out over two cables like the one shown below; the top connector is the 8-pin and the bottom is the 6-pin.

yes you are correct but i belive the purpose of the psu ( as most the RP's are ) sli capable or crossfire capable @ 750 watts rating ( continuous ) maxing @ round 825 - 850 watts is more then capable of handling such a task . it may require some fiddling with the cables ( put one 6 pin connector on #1 card and the 8 pin on card 2 then put the other cable as 8 pin on card 1 and 6 pin on card 2 ) to evenly distribute the amps , if your card has 2 Pci-e connectors . but depending on type of card's he is running if its a ultra or 2900 Xt i would recomend the 850 watter , again i think the 750 be more then capable

edit: just to add that listing i dont think has been updated latly as the 750 and a couple others from cm are fairly new ...

I went ahead and RMA'd it with NewEgg as they wanted it before I opened it, so not sure if it would have done the trick or not. Did end up getting the 1k Cooler Master, so should have no worries now.

Now I have my system built, with the CM Stacker and ready to go once I get the power supply. What an easy case to work with. I know this is for another area of the forum, but I just love the case. Only thing I couldnt figure was where to put the CM Stackers audio and mic jacks, as I am not using Intel Audio, but rather a creative X-fi. I guess best thing was just to tuck that cable away and not use the jacks. The Thermalright cooler BARELY fits the box though, so beware, I had to remove one of the fan holders in the side door to make it work. cant wait to power it up.
