What Poer Supply calculater to trust ?

AdGo · Apr 14, 2015

My PC specs-
Intel core i5 4570
Sapphire AMD/ATI Radeon Dual-X R9 270X with Boost OC 2GB DDR5 Graphics Card
Corsair Vengeance 8 gb ddr3
1 cabinet stock cooler 120mm
Gigabyte GA-B85-D3H Motherboard.

I tried many calculators like Cooler master one, extreme.outvision, etc.
But each one is giving different answers.
Can someone PLEASE help ?

I use http://extreme.outervision.com/psucalculatorlite.jsp

But for your build, a 500W PSU should be the go - mainly due to the graphics card. See the card spec for a power supply.

If you're not planning on overclock your GPU at all you'd be fine with this

Otherwise I'd go with something closer to 500W, of quality, as noted above

i7 Baby,
I saw my GPU specs on sapphitetech.com and the recommended was 500w and 600w for crossfirex

2 x 270Xs in crossfire need 700W per RealHardTech

Either the 520 or 550 Seasonic, XFX 550 or Antec HCG 520M
