What Power Supply for GTX 660 (non Ti) Sli

[JamesCrimson]

ok so here are my specs

i5-3470 3.2 ghz
gtx 660
CX500 PSU
Gigabyte Z77 DS3H

I wanna buy a new mobo, another gtx 660, and a quality power supply. its recommended to get a 700watt or so psu. I found this 850 watt psu for 50 bucks and it sounds great but the low price has me thinking is it good.......http://www.ebay.com/itm/NEW-850W-SLI-Silent-140mm-Fan-ATX-Gaming-Power-Supply-EPS-12V-SATA-PCIe-UL-Cord-/251506367552?pt=PCA_UPS&hash=item3a8ef29c40

750 watts (or higher) Corsair HX or AX series - Seasonic is also fine.

Pick one from this list: http://www.newegg.com/Product/ProductList.aspx?Submit=ENE&N=100007657%2050001459%2050001697%2050001669%20600014093%20600014094%20600014095%20600014097%20600473536%20600473331%20600473332&IsNodeId=1&name=Ready

I will check the one you listed and report back.

I have a simple rule about PSUs.
Step 1:
If you want 500W - don't pay less than 50 bucks
If you want 600W - don't pay less than 60 bucks
If you want 700W .... etc, etc.
(Except if there is a wild promo or something)

Step 2:
Best brands and models that I can immediately think of - Seasonic, XFX (made by Seasonic), Corsair (TX RM HX AX AXi or worst case - GS if you are really on a budget), Be quiet!, Rosewill Capstone series and few others I can't remember now. Stick to those brands and models and you will be happy.

Based on this I would stay away from this one and buy the Corsair HX or AX series. http://www.newegg.com/Product/ProductList.aspx?Submit=ENE&N=100007657%2050001459%2050001697%2050001669%20600014093%20600014094%20600014095%20600014097%20600473536%20600473331%20600473332&IsNodeId=1&name=Ready

I have this one: http://www.newegg.com/Product/Product.aspx?Item=N82E16817139011 in one gaming computer running for over 4 years.

Corsair AX 850 similar to this one: http://www.newegg.com/Product/Product.aspx?Item=N82E16817139044 on another gaming computer running for 18 months.

This is your best bet. For under 85 - you can't get anything descent. Better pay 20-30 bucks more and let it last for 3-4 years, then to get a 1-2 year time bomb. Cheers and good luck.

For a system using two GeForce GTX 660 (non-Ti) graphics cards in 2-way SLI mode NVIDIA specifies a minimum of a 600 Watt or greater system power supply that has a maximum combined +12 Volt continuous current rating of 36 Amps or greater and that has at least two 6-pin PCI Express supplementary power connectors.

Total Power Supply Wattage is NOT the crucial factor in power supply selection!!! Sufficient Total Combined Continuous Power/Current Available on the +12V Rail(s) is the most critical factor.

XFX TS Series 550W (P1-550S-XXB9 / XPS-550W-SEW)
• OEM: Seasonic
• maximum combined +12 Volt continuous current rating of 44 or 45 Amps <===== More than sufficient for your intended system configuration
• one 6-pin and one (6+2)-pin PCI Express supplementary power connectors
• Modular Output Cables: No
• Official Intel Haswell Compliance: Yes
• 80 PLUS BRONZE Efficiency Certification
• 5 Year Limited Warranty

ko888........are you sure? 550 watts doesnt seem like enough. Will it cover the two 660s barely or will it have a little more room for expansion?

Absolutely sure. Take a look at the following system power consumption graph. You will see a heavily overclocked Intel i7-3960X Extreme Edition 130 Watt TDP CPU with two, what I assume to be, MSI GeForce GTX 660 Twin Frozr graphics cards in 2-way SLI mode. The total system power consumption is 482 Watts for that system. Most of it is drawn from the +12V rail(s).

Your system configuration will definitely draw a lot less power since you're using a stock clocked 77 Watt TDP CPU and a less power hungry motherboard.

You can move up to this one if you want more spare capacity, since it's still within your budget:

XFX Pro Series Core Edition 650W (P1-650S-NLB9 / XPS-650W-SEW)
• OEM: Seasonic
• maximum combined +12 Volt continuous current rating of 53 Amps
• two 6-pin and two (6+2)-pin PCI Express supplementary power connectors
• Modular Output Cables: No
• Official Intel Haswell Compliance: Yes
• 80 PLUS BRONZE Efficiency Certification
• 5 Year Limited Warranty
