Brand new......should last a month or two. Yep.....or until that cheap 2 transistor 5vsb circuit goes overvoltage and takes out your mother board with it!

I searched the model number ATX-S628 on Google to find more pictures of this power supply. It appears that Golden Field sells another version of their ATX-S628 PSU for the Chinese market, nicer in appearance and slightly different than the one they make to export (the ATX-S628 that I have).

It comes in a silly looking light teal plastic tub with blue handles (which in my opinion is excessive packaging for a power supply), and has a 140mm fan (also making it slightly longer) along with all cables sleeved. The PSU I got came in a usual decent-sized cardboard box, equipped with a 120mm fan, and only the main ATX connector cable sleeved on the one that I have. The Chinese version appears to also have passive PFC (judging from seeing an inductor inside the front of the PSU in the pictures), and can only accept 220V AC. The one I have doesn't have any sort of PFC in it, and has a switch that can switch between 115 to 230V AC. I wonder if the Chinese ATX-S628 can also be found in Europe, due to power supplies there also made only to accept 220V AC.

Here are the best pictures I could find of it:










Even with these mainly cosmetic differences, the internals appear to still be the same (image from Golden Field website):

They not only don't give you a switch...
... They slap a sticker over the hole for the switch...

In China most shopping is done on foot-subway-bus. [Been there, done that.]
Boxed PSU is a pain in the butt to carry around when you have other stuff to do.
Maybe.... They think...
If they give you an easy to carry tote then you might buy more at the PC shop.

But wouldn't the shops have plastic bags to put stuff in, like they do here?

Would you put a hard drive in a plastic bag and tote it around all day?
Especially as they usually come bare [no retail box] over there.

I used to take duffel bag or a back pack with me because each place usually gives you a tiny bag just big enough for what you bought there. That way I could put all the tiny bags in my bag and only keep track of one bag.

Remember I said -> .. Maybe.... They think...
Got to be some reason they think it's a good idea.

Sorry to revive an old thread but...

This Goldenfield PSU has been reliably powering this system configuration since the start of August:

Intel Core 2 Quad Q6600 2.4GHz quad-core processor (Socket 775)
8GB DDR2-800 RAM (4x2GB dual channel)
MSI P6N SLI Platinum motherboard
Sapphire ATI Radeon HD5770 1GB GDDR5 PCI-Express x16 2.1 video card
Maxtor DiamondMax 23 STM3500418AS 500GB SATA-II 3.5" Hard Drive
Goldenfield S628 ATX Power Supply
Microsoft Windows 7 Professional x64
Antec Three Hundred mid-tower case

Voltage readings from the motherboard are:
+12V = 12.144V
+5V = 5.003V
+3.3V = 3.328V
+5VSB = 4.944V

All voltages are stable, no fluctuations. The computer runs perfectly.

What is the ripple?

What is the ripple?

Dunno, don't have a good oscilloscope to check that. This is just serving as a temporary PSU while funds for a better one are saved up.

BTW, this isn't one of my PCs, it's a relative's.
