Good Power Supply for 100$
Anyone knows a good PSU that can handle this Graphics card: R9 270X OC with boost for 100$?
XFX 550W PRO550W Core Edition $49.99 after mail in rebate.
Very high quality PSU, made by Seasonic, arguably the best PSU maker there is right now.
For $69.99 after mail in rebate you could jump up to a Corsair TX650W
But the xfx550W would be more than enough, including room for overclocks.
@OP: I think you are misunderstanding what the efficiency rating is referring to. I could be wrong.
I sent a PM to Ko888 (resident PSU guru) and he said:
At the full power draw of 550 Watts from the DC output the PSU operates at a conversion efficiency of 82% (from JonnyGURU.com's measurements during their review of the XFX550W). This means that the PSU will draw 550 Watts ÷ 82% = 670.7 Watts at its AC power plug.
The efficiency rating refers to how efficiently it draws power from the wall to achieve it's wattage. It is not referring to how much of it's rated wattage is actually being delivered.
