I have the fallowing items in my system and I need to know how many watts I need for my PSU. Thanks in advanced. MOBO: GIGABYTE GA-990FXA-UD5 AM3+ AMD 990FX SATA 6Gb/s USB 3.0 ATX AMD Motherboard Graphics: ASUS GTX660 TI-DC2O-2GD5 GeForce GTX 660 Ti 2GB 192-bit GDDR5 PCI Express 3.0 x16 HDCP Ready SLI Support Video Card- In 3 way SLI mode. CPU: AMD FX-6350 Vishera 3.9GHz Socket AM3+ 125W Six-Core Desktop Processor FD6350FRHKBOX RAM: G.SKILL Ripjaws X Series 16GB (4 x 4GB) 240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800) Desktop Memory Model F3-12800CL9Q-16GBXL More about : watts power setup noobuilder1 May 21, 2013 2:50:34 AM Triple SLI 660ti's with a AMD FX 6350??? You may find a bit of a bottleneck right there.... Wow, but to answer the question minimum of 850w but I would push it to 900 to maybe even 1000w to be on the safe side. Good luck! fudoka711 May 21, 2013 3:24:17 AM Newegg has a simple rough wattage calculator. For the info you did not mention, I added in a DVD-RW drive and a 7200rpm HDD. Power supply requirement came out to: 824W You should get a power supply that supplies around 20% more power than that to be safe - so a 1000W PSU would be necessary. Are you sure you want to pair 3 660ti's with the fx 6350? I wouldn't get anything under the fx 8350 (or core i5-3570k) because I'm pretty sure you're going to have a heavy bottleneck while gaming.

I would also go for a minimum of a 1000w good brand PSU. OCZ/Corsair/Seasonic etc Can't find your answer ? Ask ! Publish Related resources How many watts do I need in my power supply for my setup?
