Help...someone bought me a diff psu than i asked for

[mastermoirich]

i received a corsair builders series cx600 when i was hoping for a xfx 650w pro series...

i am getting a 7870 2gb, asrock z77 extreme 4, 120gb ssd, i5 3570k, Cooler Master Hyper 212 EVO 82.9 CFM Sleeve Bearing CPU Cooler, 8gb 1600mhz ram,

Will this psu be sufficient?

bc i also found a
Corsair 650W Power Supply (CP-9020039-NA) which is in the Tx series (which someone also told me was good)

and while i'm at it...is this ram decent?
Corsair XMS3 8GB (2x4GB) DDR3 1600MHz Desktop Memory (CMX8GX3M2A1600C9)

For a system using a single reference clocked Radeon HD 7870 GHz Edition graphics card AMD specifies a minimum of a 500 Watt or greater power supply. The power supply should also have a combined +12 Volt continuous current rating of 28 Amps or greater and have 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) rated at 45°C - 50°C ambient temperature, is the most critical factor.

You may find power supplies on the market that supply more than enough Wattage to run the system. However, some of them lack Sufficient Amperage capacity on the critical +12 Volt rail, which is necessary to properly power the critical components in the system (i.e. CPU and GPUs). This is the reason why graphics card manufacturers overstate the power supply wattage, usually by at least 50 Watts, to take into account those power supplies that have the weaker +12 Volt rail(s).

The Corsair Builder Series CX600 V2 (CP-9020048-WW), with its combined +12 Volt continuous current rating of 46 Amps and with two (6+2)-pin PCI Express supplementary power connectors, is way more than sufficient to power your system configuration with a single Radeon HD 7870 GHz Edition.

The CMX8GX3M2A1600C9 is 1.65 Volt memory modules. You need 1.5 Volt DDR3 memory modules.

Wow this was extremely helpful. Thank you very much. The ram voltage was confusing me because when i typed in the model # at newegg.ca and some of them say 1.65 and some say 1.5 all with the same model #. And frankly, bestbuy.ca gives minimal information.

Hi

Psu will be fine...

All the best Brett

I looked on Corsair's web site and the specifications for the CMX8GX3M2A1600C state that it is 1.65 Volts.
