I am looking for someone to advise with regards to PSU wattage needs. :] Current build: Coolermaster HAF 932 Full Tower Case Asus P8P67 Pro (Revision 3) Intel i7 2600k Sapphire HD6870 Coolermaster Silent Pro Gold 800W Corsair Vengeance 2x4GB 1600Mhz 2x WD 500GB 7200RPM SATAII 2x DVD+RW 22x SATA PCI Wireless-N Adapter Any response would be much appreciated, Pinny~ :> More about : crossfire psu wattage anort3 April 23, 2011 10:57:37 PM You should be fine to add a second 6870 with an 800w PSU. Granted it's not the best 800w unit available, but it should be fine. pinlope April 23, 2011 11:05:25 PM anort3 said:You should be fine to add a second 6870 with an 800w PSU. Granted it's not the best 800w unit available, but it should be fine. I am also considering overclocking the 2600k (to around 4 Ghz) alongside the new GPU, would this sway your opinion any on purchasing a better PSU? Also, I'd be very grateful if you could list a couple of PSU manufacturers and product lines that are better recommended.

With that setup you have I would trust a quality 750w unit from one of the manufacturers I listed. Maybe go 750-850w just to give you plenty of headroom. anort3 April 23, 2011 11:17:26 PM Here are a few nice 850s. http://www.newegg.com/Product/Product.aspx?Item=N82E168... http://www.newegg.com/Product/Product.aspx?Item=N82E168... http://www.newegg.com/Product/Product.aspx?Item=N82E168... http://www.newegg.com/Product/Product.aspx?Item=N82E168... pinlope April 23, 2011 11:23:08 PM Wow. Thank you very much Anort. :]]] Your responses have been quick and useful. Now I just need to find a modular one. jyjjy April 23, 2011 11:29:42 PM Cooler Master in general is not a particularly good brand but the unit he has is high end, 80 plus gold certified and more than enough for his needs even with everything fully OCed. There's no reason to replace it. anort3 April 24, 2011 12:04:50 AM I said that in my first post. It's plenty for what he has listed. dhicks19 April 27, 2011 9:57:34 AM +1 the psu you have currently will be fine iam2thecrowe April 27, 2011 11:08:01 AM http://www.hardwaresecrets.com/article/Cooler-Master-Si... <- review Can't find your answer ?
