need help picking a power supply

djcrow · Jun 27, 2013

I'm having trouble picking out the right power supply for this build.

List on PC Part Picker
cpu: Intel i5-4670
mobo: Gigabyte GA-Z87MX-D3H
ram: Corsair Vengeance 8GB
hdd: Seagate Barracuda 500GB
gpu: EVGA GeForce GTX 650 Ti Boost
case: Corsair 350D
optical: Lite-On iHAS124-04

I know I need a minimum of 500W, that's about all.

Check out corsair on newegg if you have a brand perferance then let people know I have had awesome luck with corsair myself.

This build is for a friend. I myself have a seagate in my current build that is great. I don't really lean towards certain brands. I have had people tell me that corsair isn't the best thing to go with as they fail more often than others. I'm not exactly believing that as a few of them haven't had personal experience with corsair (i.e. fanboys).

For a system using a single GeForce GTX 650 Ti BOOST graphics card NVIDIA specifies a minimum of a 450 Watt or greater system power supply that has a maximum combined +12 Volt continuous current rating of 24 Amps or greater and that has at least one 6-pin PCI Express supplementary power connector.

For a system using two GeForce GTX 650 Ti BOOST 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 33 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!!! Total Combined Continuous Power/Current Available on the +12V Rail(s) rated at 45°C - 50°C ambient temperature, is the 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.

The XFX Core Edition PRO550W (P1-550S-XXB9), with its maximum combined +12 Volt continuous current rating of 44 Amps and with one 6-pin and one (6+2)-pin PCI Express supplementary power connectors, is more than sufficient to power your system configuration with a single GeForce GTX 650 Ti BOOST graphics card. It is also more than sufficient to power your system configuration with two GeForce GTX 650 Ti BOOST graphics cards in 2-way SLI mode.

Based on what you said, I picked out a few others as well. This build is Micro-ATX so I'm leaning towards a modular psu. would any of these get the job done and last a while? (I'm also including the XFX you suggested.)

XFX Core Edition PRO550W
Rosewill CAPSTONE-550
CORSAIR CX600M
SeaSonic S12II 620 Bronze
SeaSonic G Series SSR-550RM

You've only listed two semi-modular PSUs. The Corsair CX600M and the Seasonic G-Series SSR-550M.

I wouldn't go with the Corsair CX600M because of the low quality parts used in its manufacturing and the use of a low end CWT (Channel Well Technology) platform. Corsair also hasn't verified whether or not it's Haswell compatible (i.e. so far only the CX700 has been verified).

Seasonic has not said that the Seasonic S12II 620 Bronze is verified as being Haswell compatible. The only 80 PLUS Bronze Certified PSUs that Seasonic has confirmed as being Haswell compatible are the M12II Bronze Series SS-650AM, SS-750AM and SS-850AM models. The Seasonic G Series SSR-550M in your list is Haswell compatible.

You'll need to remove the XFX Core Edition PRO550W from your list too since it hasn't been verified as being Haswell compatible. All of XFX's PSUs are made by Seasonic so they should be following Seasonic's Haswell compatibility list.

Some Haswell compatible semi-modular or full modular PSUs:
Rosewill CAPSTONE-550M
Seasonic G Series SSR-550M
Seasonic M12II 650 SS-650AM
XFX P1-650X-XXB9
CORSAIR Enthusiast Series TX650M
Seasonic SSR-650RM
CORSAIR HX series HX650
