  1. yeah. no worries. Even if you overclock the hell out of the 750k it still is plenty of power for a 650ti boost. You could even get a 660.
  2. Geforce GTX 650Ti Boost - requires 24 Ampere and a 450W PSU minimum. But it will depend on the make/model of PSU, so what's yours ?
  3. This is it here: Ultra LSP Series V2 450-Watt Power Supply - ATX,4x SATA, PCI-E, 20/24-PIN,Thermal Controlled, 135mm Fan, Single +12V Rail, Short Circuit, Over-Voltage and Thermal Protection, 3-Year Warranty, http://www.tigerdirect.ca/applications/SearchTools/item-details.asp?EdpNo=7850411&CatId=1078

  6. wait..Do you own the PSU already? or are you thinking of buying one?
  7. Sorry, yeah, already have it, do I have anything to lose by trying it? If it doesn't cut it, I can always stick my 8600GT back in until I get a bigger PSU (which I would be getting at some point anyway, eventually I want to OC the CPU)
  8. Best answer
    What would happen if your PSU can't cope with the load:

    •bad 3D performance
    •crashing games
    •spontaneous reset or imminent shutdown of the PC
    •freezing during gameplay
    •PSU overload can cause it to break down

    Sorry to say your PSU is not a trusted one, so replace it ASAP, to protect your components. Its a Tier 5 PSU. Not Recommend for stressful situations. May not be able to put out full rated power above room temperature, and may slightly fail to meet ATX specs.
