Gtx 670 work on my psu?

Solution
No, do not run a GTX 670 without a better power supply, you are a bit short on total wattage for being safe, and it only has a single 6 pin PCIE power connector. The GTX 670 needs two, and with the low quality power supply you have, it's is not likely that a power adapter will be good to use. There are some very cheap Seasonic models not out there, but depends on your area and local markets. This 620 watt unit is just $35 after a rebate https://www.newegg.com/Product/Product.aspx?item=N82E16817151096
