Will a gtx 770 run on a Cooler master GX 450w?

Hello, i've been looking around for a while on the internet trying to find a new graphics card, and the gtx 770 just came out and I thought it would be nice to buy it ^.^. But there is one problem tho, will it run on a gx 450w PSU?

Here are my specs:

PSU: Cooler Master GX-450w
MoBo: MSI MS-7641
CPU: AMD-FX 6100 @ stock speed 3,3 Ghz and 3,6 ghz boost (not planning OC)
GPU: ASUS GTX-550 Ti
RAM: 8 gigs corsair DDR3 1333mhz I believe, not sure

Here are the specs for the GPU:

Thank you for reading

*Note - Not planning any overclock on the GPU

  1. Definitely not. I'm sorry to be the bearer of bad news, but the 770 requires at least a 600W PSU. Further, it is recommended to have 42A on a +12V rail.

    Edit: that PSU has 35A on the +12V rail
  2. i wouldn't risk it, get a 550-600W one from Antec, Corsair, Seasonic or XFX
  3. Would you like me to recommend PSU compatible with that GPU?

    You're going to have trouble finding a high-end GPU compatible with that CM PSU because it doesn't have the PCIe connectors that the 760 or 770 require. You would have to use an adaptor. And frankly, I wouldn't feel comfortable using a $5 adaptor for a 300W $400 piece of equipment.

    Okay, thanks for the fast reply ^^, if you have any links to a good cpu (was going around 50-70 euro's/ 60-110 dollar)

    Hope you mean PSU, if you mean that get a CORSAIR TX Series CMPSU-650TX 650W

    Not nitpicking about the wattage, but the model. The GX 450w is actually excellent.

    i would go for the M version of that one
  8. What about a Geforce 670? It's surprisingly frugal with power, only needs 30 amps so should work fine.

    His PSU doesn't have the required PCIe connectors. 670 needs 2 6-pin. His PSU has 1 x 6+2-Pin. He would need an adaptor since his PSU is not modular.

    That was my first thought. Whatever PSU the OP goes with, he'll need 1x6-pin and 1x8-pin to power a 770.

    Thank you my friend! I will have a look at that!

    Exactly, that's my point, a PCIe power adaptor is, what, about £2 on Ebay? Far, far cheaper than buying a whole new power supply.


    Edit: looking at UK prices a Geforce 670 is around £280.

    A Geforce 770 + power supply is more like £400.

    I know which one I'd go for!

    hmmm is it smart to run a 2 pounds adaptor on a 280 pounds gpu?

    I don't really understand your point, it's just 2 inches of copper electrical wire, how much should it cost?

    Well, IF it breaks, what are the risks? I mean, its 2 pounds
  20. Break? It's just a wire, there is nothing to break:

    Let's say you somehow managed to cut the wire in 2 with scissors or a knife or something somehow, then the graphics card doesn't get any power and doesn't turn on, you get a black screen on your monitor. You then go and buy another cable and it all works again.

    But, you know, it's literally just a piece of copper wire that goes froms a 4 pin connector at one end into a 6 pin connector at the other.
