Computer keeps crashing when playing games

Hi so I just got a Zotac GeForce GTX770 and every time i start a game it crashes my computer. I think it's a problem with the PSU. I have an antec 650W PSU, and every time i play a game the fan speed increases until the system shuts down. Doesn't even bluescreen it just crashes. I originally thought it was the drivers (there seems to be plenty of problems with them), but the more I look into it I just think that i'm using too much power. My other specs are; intel i5 3350P 3.1GHz, mobo is MSI b75MA P45, 8GB of ram. I can't even get through a round of battlefield with this card. I'm really not very tech savvy so any advice would be greatly appreciated. Could somebody explain to me what I could have done wrong during installation? I've tried using different different pins from the PSU but as I said i'm new to this and nothing seems to be working. Thanks in advance for any advice

Right off the bat I'd probably say that your GPU is probably causing your power supply to overload.

I would have thought that 650 would have been more than enough to power this rig though?

Is it atleast bronze+ certified if not then its probably a power supply issue

How can I tell? There doesn't seem to be any stickers or anything on it that would indicate that it's bronze certified. That probably means it isn't right?

It would be on the box it came in. The 12v rail rating is important and is usually lacking on low end power supplies

Monitor your GPU temps while playing, and report back with results.

The stated wattage doesn't really have anything to do with how the power supply performs. For instance Cooler Master will advertise a power supply as being 460W, but in stress tests, it will really only put out about 420W, so a GPU would actually overload the power supply. It really has to do with the quality of a power supply and how it's really constructed. It could have a super high wattage, but if it's poorly constructed, it won't meet the advertised output. Distributors like Cooler Master lie all the time about the stated wattage on a power supply, but in real world tests they don't get the wattage advertised.

he isn't using a cooler master psu, he is using an Antec which are a very reputable brand, that's not to say the unit isn't faulty, happens to every prand every now and then.
Does When you say your pc crashes, does it actually power off? Have you plugged in the psu connectors properly to the gpu? not using molex double adaptors I hope? no power shorting out to the case, remove the components from the case and test on a bench. checked your voltages, cpu and gpu temperatures with hwmonitor? if a heatsink is not installed properly you could be on the verge of overheating already and loading the game pushes it over the edge. Lots of things to do to try and sort this one out before going to blow money on anything.

I was using that as an example. My point I was trying to make is that the cheaper a power supply is, the more likely it is to be poorly constructed, and the more likely the manufacturer is to lie on the label. No power supply manufacturer / reseller is immune from this, Antec included. Cooler Master is the best example of this, but the cheaper you go on a power supply the more likely it is to cause lots of problems.

It's not overheating. Not even close. I've double checked that. I'm using the molex adapters that came with the card, is that not good? And yeah it powers off, then restarts. As I said it doesn't even seem to bluescreen and bluescreenview doesn't log any of the crashes. Can somebody maybe give a step by step guide to how I should be powering the GPU from the PSU?

Your psu should have the connectors to power the gpu on it if not id consider getting a new psu to make sure atleast one u can borrow to test this

Yeah I think I see the problem. I got a Radeon 6670 with the computer which draws its power from the motherboard, so one of the one of two +12V rails is powering the motherboard in JPWR2. The other I put to the card and I had a +5V rail going to it, both going through molex adapters because the PCIe adapters were wrong. I see now that when I'm booting up games it's causing it to crash. Looking at the adapters on the other rails, there's no 4 pin PCIes to replace the +12V rail. Is it worth trying the get more molex adapters and trying to sort it out? Or what other solutions are available? Thanks again guys, i'm new to this and it's kinda making my head spin a little
