Regardless, you ended up with the right answer that a 660W is way too high and a 400W is still too high. However, the Platinum-rated PSU is still probably gonna be the most efficient - it's very difficult to get platinum-rated and it's gonna have some very efficient internals. As you get overall more efficient the point of peak efficiency widens a fair bit - not that it's really that different to begin with.

A PSU's rating is maximum wattage, and depending on the unit in question typically 50-100w below rating is what the unit is capable of 24/7. If you have a Gold or Platinum unit anywhere between a 400 and 500w system would be perfect for your machine to be running full load 24/7.
This does not account for overhead because we are talking 24/7 usage. Take note, I'm taking your heat into consideration from our previous convo.
To finalize, how much wattage you pull is how much wattage you pull. The end result will be the same on any decent PSU regardless of usage percentage unless you kept them cold because they will already be hot.
Yami and PPM,
Ok, thanks for the info. I am still not sure which way to go.
I cannot find a 400 Watt Seasonic hybrid Platinum anywhere that has a half way decent price [most are over $175].
I am looking for a good deal on a 400 watt Platinum hybrid, but I must have this security rig up and running within one week.
Here's what I have on hand:
CORSAIR CX430M Bronze
PC Power & Cooling Silencer Mk III 400W Bronze [sent off the broken one yesterday, hope to have the new one asap.
Seasonic 660XP Platinum
I think I have changed my mind on my computer build. I would like to use an Intel i7-3770k instead of the Intel g2020. So here's the components I would like to use:
Cooler Master Elite 120 Advanced - Mini-ITX Computer Case
Intel i5-3570k or Intel i7-3770k
ASRock DDR3 1333 Intel - LGA 1155 Motherboards (B75M-ITX)
Corsair Vengeance RAM 1600 8GB
2-Scythe Gentle Typhoon 120mm x 25mm Fan - 1850 RPM case fans
2-Coolermaster fans 120mm and 70mm.
Modified ARCTIC COOLING A7P-75000023 92mm CPU Cooler [will shave/mill 5/8" off the top]
Intel 160GB SSD
Seagate 4TB HDD or WD Red 3TB
So what would be the best way to go for now [hopefully later I can find a good deal on an excellent 400 Watt Platinum Hybrid.
