Hi there,

Western Digital WD Blue WD3200AAKS 320GB 7200 RPM 16MB Cache SATA 3.0Gb/s 3.5" Internal Hard Drive -Bare Drive

and the power supply is:

I want to buy a gtx 760.

I will not do a SLI in a future, also I will not overclock the GPU or the PSU!

so, is the PSU good enough?
 
Solution


Short answer, is...


Short answer, is no. The min requirements for that are 500w. You would be taking a real chance with your current PSU trying to run it.

Time for an upgrade if you want the card.

ok, what if I get the gtx 660ti, is 450w ill be good enough?

 


+1. 450 watts is absolutely ample, but if you try to get anywhere near the rated power from a bad quality PSU then it'll die. I bought a Thermaltake PSU a couple of years ago (using 300 watts less than it was rated for!) and even then it died after six months.
 


Yes. GTX 760 shows a total draw power of 170W. The remaining system components you've listed would require roughly the same amount of power combined.



No. Would not recommend. It has a split 12V rail @14 and 13 amps a piece.

Get a quality unit with a single rail and 450W would suffice, provided you don't plan on major expansions to the system.
 
Im running a evga gtx 760 on a 450 watt silverstone sfx psu, No issues. 760 doesn't draw that much power. Read up
