is a 650w power supply good enough for a R9 290X or is a 750w better?

my complete build is:
Processor: i5-3470 3.2ghz
RAM: 8GB
HDD: 1TB
SSD: 128GBx2

650W is enough to power your system and a single 290X, assuming your PSU will provide at least 33A on the 12V+ rails.

If the psu is of good quality, then 650w is fine.
If the psu is a cheap unit, do not buy it at any wattage.

Quote:
Here is Guru3D's power supply recommendation:

AMD R9-290X - On your average system the card requires you to have a 550~600 Watt power supply unit.
AMD R9-290X Crossfire - On your average system the cards require you to have a 800 Watt power supply unit as minimum.

If you are going to overclock GPU or processor, then we do recommend you purchase something with some more stamina.

Would these be fine? Cooler Master GXII 750W 80 Plus Bronze Power Supply or Cooler Master G650M 650W Semi-Modular 80 Plus Bronze

I wouldn't recommend them, have a look at something from xfx, antec, seasonic or an evga b2 or g2 power supply.

Coolermaster is not highly regarded as a quality psu.
Look for Seasonic, XFX, or antec.
Here is a list to help:

Would this be good then? EVGA SuperNOVA 750 B2 80 Plus Bronze

While I would say brand name is a reason not to buy, brand name should never be a reason "to buy" a PSU. Because very manufacturer who makes good or great PSUs also makes some pretty crappy ones.

For example:

Corsair AXi / HX 650 - 850 = almost perfect
Corsair TX V2 = very good
Corsair RM = Some decent / some bad
Corsair HX 1000 - 1050 = less than desirable
Corsair CX or C anything = to be avoided

Antec HCG / HCP = Good

Seasonic X Series = Perfect
Seasonic M12 = Almost perfect
Seasonic S12 = Very good

EVGA SuperNova G2 / P2 = Almost perfect
EVGA SuperNova B2 = Adequate

XFX Core Editon = Very Good
XFX Pro / Black / XX = SOme almost perfect / some very good.

well adequate is good enough for me if it breaks I can just by another brand I currently have a xfx 550w but with the new gpu I needed to upgrade it. also I am trying not to spend to much but thank you for the information will keep in mine when I buy it.
