corsair 700w(56amp 12v rail) with 2 gpu's?

post #1 of 5
Thread Starter 
ok i have a gtx 260 core 216 55nm (171 watt) on the pci-e plug and then a 8800gt connected via 2 molex with a converter note the only reason the 8800 is there is for monitor support so its completely underclocked down to 300mhz core clock (i am not worried about ruining this gpu at all seeing as its a cheap old used one that i already did a gpu bake on just to get it working again)
is this perfectly fine for the psu?

also i have another gtx 260 exactly like the one i have now (the core 216 55nm 171w) and was wondering if there is any way i could get away with both at once

power supply specs
700W total 672w on the +12v rail +3.3V@25A, +5V@25A, +12V@56A, -12V@0.8A, +5VSB@3.0A

http://www.newegg.com/Product/Product.aspx?Item=N82E16817139024&Tpk=corsair%20700w

if i added the second it would be with 2 molex to pci-e converters or 1 from the psu and 1 molex converter each

also online power supply calculator says it would take 556w with my current config (not including the 8800gt of course since it would be replaced with the 260) and 2 gtx 260 core 216's and thats with 100% load and 100% cpu tdp+oc

This would probably have been better off in the power supply section tongue.gif

I'm fairly certain a 700w PSU should be able to run all of this. A 750w PSU can power an overclocked 2600K and two GTX 580's. The GTX 260's use substantially less power than a GTX 580 (TDP for stock 260 is 182w, TDP for 580 stock is quite a bit over 200w). The 8800GT as PhysX and extra monitor support won't pull much either. The only thing I'm not sure about is the OC'd FX-4100. Bulldozer will pull quite a bit of power when OC'd.

I'm willing to bet your power supply can handle it. To make sure though, I'd recommend going to the PSU Calc Thread and checking in case you haven't already.

Hope I helped! thumb.gif

Thank you for that link this tool looks awesome tongue.gif and i was thinking that it should handle it since it seems to be a bit over qualified for only one gpu and ya i was thinking i should have posted there right after i had posted it

If you're going to get a new PSU, I would get one that actually has the proper PCI-Ex connectors, at least for your two main cards. If buying a new one, you might as well.

Even if you have to step down to a nice 650W unit to get them due to costs, you'd be better off w/that if it has the 4 needed connectors. Then run the 8800GT off of molex.
