I'd go with the Corsair. The Antec is a decent PSU, but it's still definitely a budget unit and it's cut down quite a bit even from the Earthwatts line.Ok, I need some last-minute buying advice...
Corsair CMPSU-400 for around $54 with $22 MIR
Antec Basiq 550W for around $62.
(prices including tax and shipping)
I'm thinking I should go with the Corsair, but am not sure about the MIR.
Also... a little worried 400W won't be enough power.
