Hi everyone, can someone please tell me if a corsair rm550w can run theseparts flawlessly or should I get the 650w, here are the parts:

CPU: AMD FX-8350 4.0GHz 8-Core

CPU Cooler: Scythe Mugen 4 79.0 CFM

Motherboard: Asus M5A99FX PRO R2.0 ATX AM3+

Memory: G.Skill Sniper Low Voltage Series 8GB (2 x 4GB) DDR3-1600

Storage: Seagate Barracuda 1TB 3.5" 7200RPM

Video Card: EVGA GeForce GTX 760 2GB Superclocked ACX

Case: Corsair 500R Black ATX Mid Tower

Optical DriveSony DDU1681S-0B DVD/CD Drive

Now I know that I can calculate the wattage online but I'm too paranoid to trust myself, so if you can please tell me if a corsair rm 550 would work perfectly or if I should switch to 650, and thank you in advance

get the 650 its best to have headspace than to have underpowered components and unwanted problems in the system

Like this previous answer, I would highly recommend getting the 650 watt psu. especially if you are going with an 80+ bronze rating, if you get a higher efficiency like 80+ gold, it will be better, but the 650 should be good to give you headroom. I checked the TDP of the gpu and it said ~170, but the overall will be roughly 60-80% or more of the 550 watt and at only bronze efficiency that doesn't leave much headroom.

Basically go with the 650Watt. a corsair axi should fit the bill, expensive though. here is the psu tier list. http://www.tomshardware.com/forum/id-1804779/power-supp... pick from the tier 1 or 2A or 2B try to avoid lower tiered. your gpu while it is not the newest, it is still expensive so you want a good clean power and reliable psu. I am working on upgrading mine aswell to a coolermaster v series. $150 might seem a lot, but a cheap one can destroy your system.

For a system using a single NVIDIA Reference Design GeForce GTX 760 graphics card NVIDIA specifies a minimum of a 500 Watt or greater system power supply that has a maximum combined +12 Volt continuous current rating of 30 Amps or greater and that has at least two 75 Watt 6-pin PCI Express supplementary power connectors. Your non-Reference Design EVGA GTX 760 SC w/ACX Cooler card requires two 150 Watt 8-pin PCI Express supplementary power connectors. Minimum system power requirement based on a PC configured with an Intel Core i7 3.2GHz 130W TDP processor.

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.

Overclocking of the CPU and/or GPU(s) may require an additional increase to the maximum combined +12 Volt continuous current ratings, recommended above, to meet the increase in power required for the overclock. The additional amount required will depend on the magnitude of the overclock being attempted.

Corsair RM Series RM550 - 550 Watt (SKU# 75-001935 / CP-9020053)
• OEM: CWT (Channel Well Technology)
• maximum combined +12 Volt continuous current rating of 45.8 Amps
two (6+2)-pin PCI Express supplementary power connectors
• Full Modular Output Cables: Yes
• Official Intel Haswell Compliance: Yes
• 80 PLUS GOLD Efficiency Certification
• 5 Year Limited Warranty

The RM550 is more than enough to power your system configuration.
