Is my PSU enough for GTX 770

[Questionable]

I bought a GTX 770 and while I wait for new drivers to come out since I read the new ones suck I thought I would ask if my PSU is ok for the card. This is my PSU:

I know it isn't the best PSU but it was what I could afford at the time. Also any power supplies you could recommend if it isn't enough? My price range is $100-$200. Also my case is a CM Storm Trooper so I need the cables to be long enough.

They don't give enough informations about the wattage. What I can say is that it's not 80+ certified and that's not good and it seems like the 12v rail doesn't have a lot of wattage. Change it as soon as you can. For 80$ you can get something way better than that.

You don't need to spend $100-$200 to get a better PSU. In fact, significantly better PSUs are *less* expensive than the $79.95 that Ultra is listed at the link. Unless you're SLIing, you don't need 750 and can get a Seasonic-made XFX 550W for aroundd $62 at last check. If you do need 750 to SLI later, you wouldn't trust the Ultra anyway and can get a Corsair TX750 for $90, and either Rosewill Capstone (a good Rosewill, made by Super Flower) or the XFX 750 for $100.

As for your current question, you could very well be OK - a lot of pretty lousy PSU can stay within ATX specs when you treat them lightly relative to the promised specs, but you're gambling and it's not a recommendation I could put my name behind.

Ultra is a mixed bag, the Ultra X4 1200 gets a 6.5 rating, the 1000 watt X3 gets a 9.5 over on jonnyguru

As for wattage ... nVidia says

http://www.geforce.com/hardware/desktop-gpus/geforce-gtx-770/specifications

Graphics Card Power (W) = 230
Minimum Recommended System Power (W) = 600W

For warranty purposes, I'd not go less than 600W for a single GPU and 850 for SLI (assumes overclocking)

Here is Guru3D's power supply recommendation:

http://www.guru3d.com/articles_pages/geforce_gtx_770_review,5.html

GeForce GTX 770 - On your average system the card requires you to have a 550 Watt power supply unit.
GeForce GTX 770 2-way SLI - On your average system the cards require you to have a 750 Watt power supply unit as minimum.
GeForce GTX 770 3-way SLI - On your average system the cards require you to have a 1000 Watt power supply unit as minimum.

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

As a minimum .....

1st tier, in order of preference .... Corsair HX850, Seasonic X Series 850, XFX Pro or Black Editions, Corsair AX850
2nd Tier, in order of preference .... XFX Core Edition, other Seasonics, Antec HCP or HCG, NZXT Hale

Does anyone recommend PC Power and Cooling? The lowest I was willing to go in terms of wattage was 650w but closest I could find was 600w http://www.newegg.com/Product/Product.aspx?Item=N82E16817703036
they also have a 750w
http://www.newegg.com/Product/Product.aspx?Item=N82E16817703038
I like them both because they are modular. Any recommendations between the 2? I also never plan on SLIing. And my 770 just got delivered...

Modular smodular

It's kinda silly to pay extra for a 100% modular PSU and then 100% of the time you must connect the 24 pin cable, you must connect the EPS cable, you must connect a SATA cable..... so why did you just pay extra for 3 extra connectors, introduce 3 potential failure points and in increase resistance and reduce efficiency ?

The hybrid modular design from most enthusiast PSU suppliers offers the best of both worlds w/ the absolutely necessary cables hard wired and all the rest modular.
