Bruiser of a 700W

[370forlife]

Got this 700W for $14.99, pulled out of a gateway FX computer. Thing is huge. Biggest ATX power supply I have seen.

Sorry about these picture's qualities. It was about 8:50 at night when I took these so the only light was the soft yellow kitchen light. Also trying out the camera on my phone, still need to fiddle with the settings.



Big guy. Here's a shot of it with a Delta DPS-700FB on top of it, which is itself a pretty big power supply. They are about the same weight.



A hem. Ignore the big grey box I put over the label. Keep ya guessing. Internal pics will come tommorow when I can get better lighting and mess with the camera settings.

(BTW, I wish coke was still 5c...)

Looking forward to seeing the kishkes.

Re: Bruiser of a 700W

Is the big fella also a delta?

Re: Bruiser of a 700W

It's HIPRO, my guess

Re: Bruiser of a 700W

I vote for HIPRO (the fan grill shape gives it away).

Re: Bruiser of a 700W

My vote is LITE-ON. Many manufacturers use that fan grille. Some more commonly than others, so it might be a hint, but I don't think it's a giveaway.

Re: Bruiser of a 700W

my vote is delta... possibly acbel...

Re: Bruiser of a 700W

i still vote delta. look at the censor block on #1. delta has a logo that small. hipro does not.

Re: Bruiser of a 700W

1 vote.

Insisting still does not get another vote...

or chance...

Re: Bruiser of a 700W

It's most definately a Delta.

Re: Bruiser of a 700W

My vote is still HIPRO Model: HP-W700WC3 LF

Re: Bruiser of a 700W

Another vote for Hipro.

Ding ding ding! Exact model.



Label, nothing strange here.



Clamshell case removed, revealing the semi-dual PCB design.



Top PCB pulled up.



The top PCB is simply for most of the primary. The heatsink cools the APFC parts, which are two 21N50C3's and a diode. Primary caps are two Elite 420V, 330uf's. Under that perforated cover is the input filter, consisting of 4 coils, 2 .68uf X caps, and 4 Y caps, with 2 more Y caps on the AC receptacle.



Bottom half. Left bottom heatsink cools the primary switchers, two IRFP460A's in two transistor forward. Heatsink above that contains the 12v rectifiers, 5 STPS20H100CT's, good for 20A for 100A combined.



OCP shunts for the 12v rails. Secondary capacitors on the 12v are a mix of 16v, 3300uf UCC's and 25v, 470uf Teapos. Those two big 12 gauge wires feed 12v to the right side of the PCB.



Here's where they end up. The inputs are filtered by some Nichicon HM's and Teapos.



The output from that heatsink is the 5v and 3.3v rails, indicating this is independently regulated. This unit seems to derive these rails by using two P60NF03's connected in parallel for each rail for a DC-DC configuration. Each output gets a choke and two Nichicon HM 10v, 1500uf.

Re: Bruiser of a 700W

Does it need to replace Teapos and Elites?

Re: Bruiser of a 700W

None are bulging, I'm not worried about them. All the HM's have a 2006 datecode, just as the unit itself was made in the 22nd week of 2006.

There are also some random small value (<1uf) Ltec's scattered around. Forgot to mention the fan is a San Ace, I can't get the model number as the fan is mounted using rubber mounts and I don't feel like breaking any of them. Also, shunts are present on the two minor rails as well.

The "CLiCK" brand transformer I have only seen in other units made by Kingnod.

Re: Bruiser of a 700W

This thing really needs a load to regulate. No load, 5v stays steady at 5.05, 3.3v at 3.35. The 12v starts at about 13.02 and climbs up to about 13.29 then the unit shuts off. With just two hard drives for a load, the 12v stays steady at 12.05v, 5v at 5.05v, and 3.3v at 3.35v. Interesting all the rails end with a 5 for some reason. 5vsb steady at 5.12v.

It also has a relay on the input that bypasses the two thermistors. When turned on, you can hear the "click" of the relay.

Nice PSU.

Re: Bruiser of a 700W

What are the dimensions of this 370? Got a scale?

[370forlife]

Re: Bruiser of a 700W

It's about 9 1/16th inch/230cm long. Width and height are standard ATX dimensions (6" wide, 3.5" tall)
