Hellsbells Posted March 2, 2009 Share Posted March 2, 2009 Hey guys, Is there any difference between a (6+2) pin PCI-E connector and a 8 pin PCI-E connector? I want to use my HX620 to power a graphics card which requires a 6 pin and 8 pin PCI-E connector. With the HX620, will I be able to use on of the (6+2) pin connectors as a 6 pin, and the other (6+2) pin as an 8 pin connector, to power this graphics card? Furthermore, my Lian Li 343B can house 2 PSU's. I have 2 HX620s in my case. Could I use one of the (6+2) pin connectors (as a 6 pin) from one of the HX620s and one of the (6+2) pin connectors (as a 8 pin) from the other HX620, to power the same graphics card mentioned above? I.e. in effect the graphics card will be powered by 2 HX620s, with each PCI-E connector having its own 12V rail. Thanks guys! Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted March 2, 2009 Corsair Employees Share Posted March 2, 2009 I would NOT suggest using 2 seperate PSUs to power the same GPU. Also, you can use a 6+2 pin connector as an 8 pin. That's the point, it's made to be flexible so it can be used as either type, 6 or 8 (6+2).

Hellsbells Posted March 3, 2009 Author Share Posted March 3, 2009 Thanks for the quick reply RAM GUY! Could I use 1 of the HX-620s to power the graphics card, hard drives and fans whilst I use the other HX-620 to power the motherboard and CPU? Cheers Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted March 3, 2009 Corsair Employees Share Posted March 3, 2009 That should be fine, you just do not want to plug in two different PSUs to any one hardware device. The voltages are regulated independently and you could cause a short if there are two separate 12v rails connected to your video card for instance.

Hellsbells Posted March 3, 2009 Author Share Posted March 3, 2009 Is there anyway that I could cause minor/major problems with any of my hardware by using 2 PSU's in the same computer? (Besides the shorting out described above) What would the effect be if this shorting out did occur? Would it kill my motherboard or GPU? The reason I am using dual HX-620's is because Im upgrading my computer, and its new power requirement exceeds what the HX-620 can provide. Rather than discard my HX-620 for a HX-1000, I thought that I could just house 2 HX-620s in the same case and make up the new required amount of power this way.

Corsair Employees RAM GUY Posted March 3, 2009 Corsair Employees Share Posted March 3, 2009 If a single component is getting two different voltages from the same rail, then it will short out, and the system will shut off. If everything is working the way it should be, then nothing will be damaged. Which PSU does our PSU Finder recommend for your system? Link to comment Share on other sites More sharing options...
Hellsbells Posted March 5, 2009 Author Share Posted March 5, 2009 It recommends HX-620, TX-650W, TX-750W and TX-850W. Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted March 5, 2009 Corsair Employees Share Posted March 5, 2009 It recommends HX-620, TX-650W, TX-750W and TX-850W. You should be fine with just a single HX620. There is some headroom built into the PSU finder, so I would not suspect you would have any problems. Link to comment Share on other sites More sharing options...
Hellsbells Posted March 5, 2009 Author Share Posted March 5, 2009 I think Ill do this; HX-620 #1 - Graphics Card - CPU - Motherboard HX-620 #2 - Hard Drives - Water Cooling Pumps - Fans - Optical Drives - Cathodes - Fan Controllers etc Does that sound as if It will work?

Corsair Employees RAM GUY Posted March 5, 2009 Corsair Employees Share Posted March 5, 2009 That should work just fine, although I'd probably only use a single HX620 if it were my system. I don't see the need to use both of them. Link to comment Share on other sites More sharing options...
Hellsbells Posted March 6, 2009 Author Share Posted March 6, 2009 I am concerned that I will overload a single HX-620. My system will consist of an overclocked quad core, 4 sticks of DDR2 ram and a graphics solution that will use in the vacinity of 250W at load. On top of that I have a water cooling solution consisting of 2 18W pumps, 10 high speed fans, 2 fan controllers, 2 optical drives, 3 hard drives and cathode lighting. I have used what is commonly refered to a reliable PSU calculator to calculate that my system should draw more power than 620W at load. Link to comment Share on other sites More sharing options...
Corsair Employees RAM GUY Posted March 6, 2009 Corsair Employees Share Posted March 6, 2009 Your HX-620 has more than enough power to run any single GPU solution made, including 299 GTXs and 4870 X2s. I see no need for 2 PSUs for the specifications you have listed. Link to comment Share on other sites More sharing options...
benniebeeker Posted April 21, 2009 Share Posted April 21, 2009 this thread might be a little dated, BUT here is what i run on a single hx620 e8600 4.4ghz single gtx 280 4x2gb sticks ram 4 hard drives 2 optical drives 6 120mm fans 1 200mm fan swiftech mcp655 water pump 2 sticks 12" cold cathode lights you have plenty of room on a single...
