Do I need a 850w power supply for my build?

[BenjaminoFree]

I recently got a MSI GTX 970 gpu and my build seems to be having problems since I installed it.
2 of my USB ports have lost power and the screen seems to be getting darker and fuzzier along with other strange effects when I play games, I was wondering if it had anything to do with my power supply (I'm not excellent with computers).

I currently have a 700w power supply, here is the rest of my build:
-GIGABYTE H61M-D2H-USB3 Motherboard
-Quad Core Intel i7 2600k 3.4GHz
-MSI GTX 970 4GB GDDR5
-8GB RAM
-64 bit Windows 7

If you could tell me any problems that you can see that would be great.
Thanks!

700 watts should be plenty. Who is the power supply built by?

Yeah definitely need to know the brand and model

Yep there's your problem. More than likely your power supply is slowly turning into a paper weight.

What exactly is the problem? It's just a bad overall supply?

Absolutely yes....definitely replace it asap

I would check the voltages before you replace it but I think the PSU is the issue. I don't even recognize that brand of PSU much less if the quality is anything good.

So would an 850 be better or should I just stick with a 700 but buy a better model?
PS: Thanks for the help guys!

Yes...try EVGA G2 Supernova...XFX or Seasonic

Thanks for all the help you guys, I'll get on this problem right away!

Buy a quality 550W-650W power supply. Rosewill Capstones are really nice (made by Super Flower) or anything made by Seasonic. XFX has a really nice 80+ bronze 550W power supply also (I think it's made by Seasonic).

850W or even 700W is total overkill for a 95W CPU and a 145W GPU. 850W is the high end of the recommendations for running GTX 970's in 2 way SLI.

Based on the advice from all of you I'm going for this one, I don't really mind spending the extra cash for a 750w just in case

I'm going to assume that it's just a bad brand and not really reliable, I've had this supply for about a year.

750W is overkill for a locked Haswell processor and a low power video card. Look for something Tier 1, 2A, or 2B from this list:

EDIT: Looks like that XFX Pro 750W is Tier 1, so it should be great. I'd only go that high if you're seriously considering SLI though.
