Hi again,
I've recently made a purchase of a new Golden Field ATX-S628 550W peak power PSU that was being sold at a local computer shop I know for $38 CAD. It actually had some weight to it, along with a few other things that made it attractive to me at that price. I'll have it on hand as a backup PSU, in case my Antec PSU fails.
It appears to be a great PSU for the money I spent on it, as it has beefier heatsinks than normal cheap power supplies, has a 120mm fan, nice dark gray finish, and comes with a decent secondary side and a transient filtering stage (two Y caps, two X caps, and a coil). The caps in this PSU are BH brand, which I haven't heard anything bad yet about them (but they do look like cheap Taiwanese caps, IMO).
The complete package.
Three shots of this PSU.
This PSU has one 24-pin ATX connector, two P4 12V connectors (that can be joined together for EPS12V), one PCI-E 6-pin connector, three 4-pin peripheral (molex) connectors, and two SATA power connectors. This arrangement I believe will suit most basic computers.
A shot of the label. Note the "Oiliness Bearing Fan" remark.
Overhead shot of this PSU's internals. Notice that it is not completely gutless.
A shot showing the transient filtering stage, and the two primary caps.
The primary caps are two BH 680uf 200V.
The best picture I could get of the KBL406 4A 800V bridge rectifier. It being 4A, the most this power supply could draw from a 120V AC outlet would be 480W.
A shot of the primary side silicon. One CET CEF02N6A 600V 1.4A n-channel transistor, along with two 13009 NPN power transistors.
Three shots of the secondary side.
A shot of the secondary side silicon. The one on the left is an S20C45C 20A 45V Schottky rectifier, the one in the middle is an S30D40C 30A 40V Schottky rectifier, and the one on the right is a U20C20C 20A 200V power rectifier. I doubt that this PSU has two 12V rails, as on the label, since there is only one power rectifier for the 12V. Correct me if I'm wrong.
The 120mm fan used in this PSU is a Yate Loon D12SL-12 12V sleeve bearing fan, which operates at 1350RPM, pushing out 47CFM of air at a noise level of 28dB.
The fan connects to this additional board in the PSU. I'm not sure what it exactly does, but I'm guessing it's some sort of fan controller, as the package indicates an "Adjustable Fan Speed Controller". If you know what it is, tell me. It has an LM339N on it.
This PSU uses an SG6105 PWM controller chip.
I haven't even powered on this PSU yet. The rating on the label is 550W, but that's the peak power rating. I would guess that this PSU's continuous rating would be at 400W, considering how the PSU looks inside, and the rating of the bridge rectifier.
