So I previously built my computer


  • Inferno Katana: Infernal LGA1156 Mainboard on Intel P55 Express Chipset from Foxcon mother board
  • ASUS HD7770-2GD5 Radeon gpu
  • 8 gb of ripjaw ram
  • intel i5 quad core
  • new zalman cpu fan
  • 750 watt thermaltake

so the thing is i recently fried my psu and i am not sure whether it was because my build uses too much power or just a bad psu so my question is what size should i get to replace it

Quantity of power as well as quality are most important when choosing supply

You can use this calculator http://extreme.outervision.com/psucalculatorlite.jsp

and this list to help http://www.overclock.net/t/183810/faq-recommended-power-supplies

You should be good with a 500w PSU

don't forget the 12 volt amperage ratings. that system should be fine with 50 amps or above.

Hi, based from the specifications supplied, the 700W Thermaltake power supply should have been easily powered your system but it could be due to just a bad power supply that caused the frying.
