650W or 750w psu?

[peti446]

Hi,
I Have an Intel I7 2600 (3.4Ghz), 8Gb DDR3 Ram (2x 4GB DDR3), GTX 750Ti, an 7200rpm sata Hard drive and 8 usb port.
So is 650W enough for my pc or do I need to aim for a 750W psu (Both from the Corsair RM serie 80 Plus gold)?
Thx for all!

550Watt is more than enough.

A 300 Watt power supply unit is sufficient for that build.

System Power Supply Requirements for a single GeForce GTX 750 Ti
• NVIDIA specifies a minimum of a 300 Watt or greater system power supply. (Minimum system power requirement based on a PC configured with an Intel Core i7 3.2GHz 130 Watt TDP processor.)
• the system power supply must also have a maximum combined +12 Volt continuous current rating of 20 Amps or greater
• the system power supply should also have at least one 75-Watt 6-pin PCI Express supplementary power connector for some of the non-reference design cards (e.g. ASUS GTX 750 Ti OC 2 GB [GTX750TI-OC-2GD5], EVGA GeForce GTX 750 Ti FTW w/ EVGA ACX Cooling [02G-P4-3757-KR]).

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

This. Unless you're overclocking your CPU, worry more about your amps and whether you'll have enough to power your GPU. You'll be more than fine with the linked PSU.

Hi,
Thx for all the answers!
I was looking and find this one EVGA 500B 500W Power Supply (https://pcpartpicker.com/part/evga-power-supply-100b10500kr) would that be ok this one has 40A on a single rail?¿ or do i need 550W

i would get 750w just for future. in case you want to add another gpu e.t.c and for overlocking.

That'll do, but i would recommend the XFX 550W unit over the EVGA unit, because XFX has a better reputation at making PSU's.

This would already be fine.

Looking from where you came from,the rm series looking at their price,could you also look at this one,

Another quick question:
I have MSI B75MA-E33 B75 Socket 1155 VGA HDMI 8 Channel Audio Micro-ATX Motherboard as moderboard nad it says that it need 4-pin ATX 12V power connector, for example the Corsair CXM 500W Hybrid Modular Power Supply comes with a 8pin CPU +12V so it would not fit in the board no? (I will need to look for a 4pin or 4+4pin right ?)
Thx for all the help!

That's the same with this psu.
