Processor: Athlon 2 x3 445 (can unlock to x4, just needing a new heatsink)
Video Card: 5670 512 sapphire

Conclusions:

To wrap up I'll characterize this one as a solid build for those who want high energy efficiency and not looking to spend over US$75 which is the average retail price on it. I bought mine through ATXpowersupplies.com though which has it for $55, which I feel makes it a much more attractive option then it does when comparing it against units in the $75 range. The Delta made Antec Earthwatts 650W reviewed here sells for around $75 and offers better capacitor brands, independent voltage regulation, better power distribution across three rails, a quieter 120mm cooling solution and of course 150 more total watts---100W of which come from an extra 8A on the 12V combined rating---all at the sacrifice of a few percentage points of efficiency though. Personally, I'd spring for the EA650 between these two choices in a heartbeat because if I wanted to save a few dollars on my electricity bill I'd keep my bathroom light off at night instead of on like I do just so I can see down the hallway when I get up to pee in the middle of the night.

What I like:

• Solid well built Delta construction
• High energy efficiency


What I don't like:

• Only one cable sleeved
• Mediocre ripple and noise suppression
• Failure to pass ATX hold-up time due to inadequate primary capacitor sizing
