One thing to note on that PSU, is it doesn't have PFC. And no.. that doesn't mean it's not a Private First Class. It means it doesn't have Power Factor Correction.
In not my own words...
| Quote: | Power Factor Correction (PFC) allows power distribution to operate at its maximum efficiency. There are two types of PFC, Active PFC and Passive PFC. All of our power supplies are either Active PFC Power Supplies or Passive PFC Power Supplies.
Active PFC
The preferable type of PFC is Active Power Factor Correction (Active PFC) since it provides more efficient power frequency. Because Active PFC uses a circuit to correct power factor, Active PFC is able to generate a theoretical power factor of over 95%. Active Power Factor Correction also markedly diminishes total harmonics, automatically corrects for AC input voltage, and is capable of a full range of input voltage. Since Active PFC is the more complex method of Power Factor Correction, it is more expensive to produce an Active PFC power supply.
Passive PFC
The most common type of PFC is Passive Power Factor Correction (Passive PFC). Passive PFC uses a capacitive filter at the AC input to correct poor power factor. Passive PFC may be affected when environmental vibration occurs. Passive PFC requires that the AC input voltage be set manually. Passive PFC also does not use the full energy potential of the AC line.
Non-PFC
Non-PFC power supplies are no longer recommended. In fact, in Europe, power supplies are now required to have either active power factor correction or passive power factor correction

I will try to read some reviews for reference. Perhaps, I will buy a new PS with my private stash of cash 
I may even change out the cooling fan on the side and front of the tower as well for good measure. The one on the side, though free spinning, seems to be making some sporadic humming vibration every now and then. I think it is a 80mm. Any recommendations on brands of cooling fans I should buy and/or avoid?

Three here plus an independent testing of my Antec PSU.

I've recently read some reviews on the Antec NeoPower 480W PSU, and it is awesome. I'm planning on buying it soon.
A good PSU costs a lot, that's a fact. |
They sure do.
I love Antec, ever since I've started using them. They were great when my voltages were fluctuating too. They RMA'ed w/o question! (The best part is, I think I broke it by allowing a molex connector to short-out a few times on the side of my metal-case)...... DOH!
