Re: Need help BFG/GR650WGSPSU

12.4 and 11.8 are in spec for the 12v rail. 12.4 on the enermax makes sense as thats a more modern, 12v heavy unit whereas the BFG is based on a older design.

Thank you 370,
OK so I plugged in two hard drives and a 120MM fan, used a home made jumper to short the green lead and a black lead on the main harness. Powers on now my readings are 12 volts on the rail, 3.3 and, 5.5 respectively. Anything else I should check or are we good to fly here?
Again Thank you!


PS I'm starting a new thread in the monitor section, for anyone who would like to follow along.

Re: Need help BFG/GR650WGSPSU

You won't get a realistic reading without load on it because the regulators are in limbo.
Attach a hard drive or two to load both +5v and +12v and check that way.

Thank you PC,
will do tonight when I get home from work.....

Re: Need help BFG/GR650WGSPSU

One final question guys, got it all together and buttoned up. But want to make sure it is putting out what it should be doing, so I used my EnerMax Galaxy 1000W with a jumper in the green and black wire on the main harness to jump start it for some readings.
The Enermax shows 12.4 on the 12 volt rail my repaired shows 11.8? Neither one is under load, both show 5V on the 5V rail and all others seem in spec. So the question is is this a good repair or do I need to do more to it?

Thank you!

How about this: http://search.digikey.com/scripts/Dk...&name=F3482-ND ?

Thank you Khron666!!
You guys are the best, now I can order and not have two different packages coming for the same thing. I'll post back soon as my stuff arrives in the mail,(with photos) again to all of you who helped me Thank you for your patients with me. I Did learn a DMM=digital Multimeter, that was from reading other postings in the monitor section(I'll break in there soon as well) I want to do my home work on that first. So much to learn from just reading all the posts that are already up, plus I'll search see if my fix is posted already(I'm learning!)

Re: Need help BFG/GR650WGSPSU

I cant find what I need, there site totally will not show me what i want. Can you suggest a maker or brand to buy, as the ones i did find were sold in packages of five for $21.00 Can someone link me to a 12A 250V ceramic fuse please

Re: Need help BFG/GR650WGSPSU

Double check this 'cause I haven't had any coffee yet...
.
5G is a code for physical size and [I think] style - 5x20mm, cartridge
The UL and probably the SA are Certification marks for UL and CSA.
.
If it was AS with no circle it would be:
A = Standard blow [vice slow or fast].
S = Silver plated contact area.
.
The Navy uses AS about everywhere because silver oxide is almost as conductive as silver and the salt air causes corrosion every where including in fuse holders.

Re: Need help BFG/GR650WGSPSU

Thank you Bonez!
One question, I get totally lost when even trying to find the fuse on that site? My fuse is 12A 250V on the other end it shows "5G then UL with a circle around it then SA with a circle around it, any help thanks!

Re: Need help BFG/GR650WGSPSU

In the USA Digikey.com and Mouser.com are usually the places to go for parts.

The rectifier is 4 diodes in a loop.
I'm not sure what your pinout is [which pin is what] but you should be able to figure it out from this.
Each diode should read low [less than 1 ohm] in one direction and very high [probably out of range] in the other.

For 2 cents more you can upgrade by 5 amps.

Thank you for the link PCBONEZ!
I'm sure I can get the blown fuse there as well, you guys are assume!!

Re: Need help BFG/GR650WGSPSU

Here's my meters, I'm gonna redo the readings again but with the blue point this time...... Pictures aint sticking heres my new readings.
1 (red probe) 2(black probe)
110.5
2 (red probe) 1(black probe)
150.00 (then climbs above199.99 then to 1--.--)
2 (red probe) 3(black probe)
1--.--(again it starts around 150.00 then climbs fast to that reading)
3 (red probe) 2(black probe)
104.9
1 (red probe) 3(black probe)
02.6
3 (red probe) 1(black probe)
02.6


4 (red probe) 5(black probe)
107.6
5 (red probe) 4(black probe)
1--.--
6 (red probe) 5(black probe)
103.3
5 (red probe) 6(black probe)
102.6
6 (red probe) 4(black probe)
02.6
4 (red probe) 6(black probe)
02.6



See if these are better..........Just realized it says "auto range" on the radio snack

Re: Need help BFG/GR650WGSPSU

Does your meter auto-range?
If it's changing ranges on it's own that might explain it.
.

I'm guessing it does as when I'd try to take readings from certain points, it would start out at like say 0.260 then begin to climb and continue for a while. If you think the blue point would do better, I can post up the same readings with it.

Re: Need help BFG/GR650WGSPSU

PCBONEZ do those readins look to low to you?
Philly Cheese Steak
If it were me I would have gotten the part numbers for the transistors and got the datasheet for them those reading look to low to me.
also what type of meter are you using.

Hey Joshnz!
I got a radio shack Digital Multimeter, as i recall it was around fifty bucks a few years back. Its the one that can fold closed and fit in your pocket, don't see a model number on it any where.
I got a better meter if you think this one may be off, its the fluke wanna be from Snap on. Only reason i used this one was the connection had corroded on the battery. I assume I can solder the battery in place to use it....

[PCBONEZ]

Re: Need help BFG/GR650WGSPSU

PCBONEZ do those readins look to low to you?

Yes. - Assuming it's out of the circuit to measure as it should be.
Should be open or at least very high in one direction. [Depends on meter.]
... And very low in the opposite direction.

Part of the reason I linked to the parts was to show these aren't like expensive or anything.

Re: Need help BFG/GR650WGSPSU

Considering it blew [and don't really know why] for 2 cents I'd upgrade anyway.

Re: Need help BFG/GR650WGSPSU

Wouldn't 10A be more than enough? At 120V input 10A would mean 1.2kW input power.
