CommanderCrazy Posted November 7, 2011 Posted November 7, 2011 Question: Does it have to be a card of the same type? (EG: Can i use a GTX470 for Main, and a GTX260 for PhysX)Also, does it need to be in a main PCI-e slot?
AxelDominatoR Posted November 7, 2011 Posted November 7, 2011 The card may be different from the main one (yes you can use a 470 main and 260 for physx). Being in a main PCIe slot is not required (better to put the main card in the main PCIe slot).
CommanderCrazy Posted November 7, 2011 Author Posted November 7, 2011 Well, i did it, but it was drawing too much power. Started frying my power supply (that smell :/ )In for a new one now.
AxelDominatoR Posted November 7, 2011 Posted November 7, 2011 Ouch! How much wattage had the burned one?
CommanderCrazy Posted November 8, 2011 Author Posted November 8, 2011 (edited) It was a 650w (720 Peak), im now getting a 900w. No harm done, i chucked in a spare (without the second card) and all parts seem to be working fine. K. I found an 850w that is better. Sticking with this one: http://www.pccasegear.com/index.php?main_page=product_info&cPath=15_305&products_id=13052 Edited November 8, 2011 by CommanderCrazy
HellsMaster Posted November 8, 2011 Posted November 8, 2011 Dual Card set up (SLI, Crossfire, Hybrid PhysX) require a huge amount of power. Your old PSU (650) is right on for your single card but you risked a lot when you put a 2nd card in there. 850w is quite good but I would have suggested to go for 900+ still in any case.
CommanderCrazy Posted November 8, 2011 Author Posted November 8, 2011 The problem is, at the 2 stores i looked at none of the sales rep's recommended the 900w ones they had in stock. They were either not 80+ little chinese things, or strangely cheap.
AxelDominatoR Posted November 9, 2011 Posted November 9, 2011 They recommended you well. Cheap ones are not really suitable for sustained 900W, but only can withstand brief peaks of it.Moreover, if your PSU is not stable with voltages, you risk frying other components. Better to play it safe.
CommanderCrazy Posted November 11, 2011 Author Posted November 11, 2011 Well crap. Ive now got a 1000w, 2 new graphics cards, 4gb more RAM, and a RevoDrive. :facepalm:
