A 750W PSU takes more power than 600W?

Hello,

I have a crap Huntkey 600W PSU. I'm looking to buy a Corsair HX/AX 750 PSU soon since it would make it futuristic and also I'm afraid my crappy PSU might blow anytime..

Will the new PSU take more power than the one Im using now?

    It's more efficient, so it'll use less power and deliver cleaner, less ripply power, too.

    Your PSU will only use what your PC asks for.

    how much power i needed...
    processor : 3770 k i7
    motherboard: Asus P8z77 vpro
    gpu: gtx 660 2gb zotac
    ram: 8 gb corsair veng/1600
    hd : 1tb
  5. If you're planning to add a second GTX 660 in SLI later on, a 750W power supply would be a good idea. If not, 550W would be sufficient.
  6. thanks for your answer..i dont want SLI so i ll use 550 w psu and one more thing is it necessary to have a cooling kit for i7 processor withot o/c

    Need? 500watt.

    Should get? 750watt+

    My recommendation if you don't want to spend much: http://www.newegg.com/Product/Product.aspx?Item=N82E16817139006
  8. thanks....what about cooling kit..is it necessary to have cooling kit with I7 3770K..No o/c

    There's no reason to get the K version if you aren't overclocking.

    No, you don't need any special cooler to run it perfectly fine at stock.

    Hmm..A CPU cooler is a must in hot countries like India.. My temps were like touching 80's and 90's with stock intel heatsink(temps were like 60-90) non OC and with reapplied thermal paste with normal case(having 3x80mm fans). A good airflow case (Corsair 500R) only could reduce temps to around 50-78. A hyper 212 EVO ultimately proved a big difference with temps 39-62 degrees at max.

    Though same cant be said for all countries..It depends on the temps and ofc the airflow in the case.

    Woah. How hot was it in your house? lol

    That is actually far, far too high for that CPU. Ivy runs very cool on stock voltage. I'm guessing the heatsink was installed incorrectly. You'd need to have fire around the case to get that sort of temp :P

    As long as it isn't 50*c in your house, the stock fan is perfectly fine.
    Ivy Bridge runs much cooler on stock voltages than past Intel CPUs.

    Around 40-45 degrees at day and around 35 at night. The stock fan is seated perfectly. I re-applied the thermal paste twice correctly to check and it was no changer. Though my gig is 2 years old, I never used to monitor my temps from a long time though. (checked once a month back and was like WTF). I immediately changed my case and bought Corsair 500R+CM Hyper 212 EVO+Arctic Cooling MX4. Still my temps are 39-62 degrees with non-oc.

    Although, same cant be said for ivy bridge. X58 platform is normally hotter, also, many guys had the same problem (many more had, just googled some):
