psu in my dad's rig baught in 2007 i can't tell the brand - Page 3

post #21 of 71
If it is the mge600wp then it's an older and outdated ATX design.
http://bigbruin.com/reviews05/imagev...file=pic15.jpg

+3.3V - 40A
+5.0v - 45A
+12v1 - 18A
+12v2 - 16A
-5.0v - 1.0A


Notice the inclusion of a -5v rail and the high +3.3 and +5v rails compared to the low +12v rails. Definitely not something you would want to use with modern hardware. And that's just based on the specs without a legitimate test using the proper test equipment to measure ripple and voltage stability. By todays standards it's more like a 450w psu than a 600. The Antec EarthWatts 430D Green has 16A and 17A on it's two 12v rails by comparison.

Given that half (or more) of the PSU's output is on the +3.3V and +5V rails rather than the +12V rail, and due to the presence of a -5V rail, it looks to be a very old design, and possibly overrated and of lower quality. Without knowing specifically what the results of that model are regarding voltage, noise, and ripple testing, and so on, I'd still say it's less than good at best, to put it lightly.

Edit: Gah, I was beaten to it a post above.

Oh yeah def. This thing almost belongs in the pre-P4 era with that power distribution. My Pentium 3 rig has a psu with similar ratios.

if i get the chance i will test it for voltage, noise, ripple testing, and so on, right before i junk it(if someone tells me how, equipment needed etc...), no wonder my 8800 gtx isn't doing so well, and the mobo beeps every time you turn it off, and overall, the whole think needs to be junked.... although i will know more Monday... be looking for a new thread by me to update....

You can't really check most of that at home as the equipment is way too expensive for the average home user. We are talking thousands of dollars to get equipment that is capable of doing it reliably. About the only thing you could check is the actual voltage output using a DMM, but that won't tell you much about the quality of the unit. That's why there are only a handful of places on the internet that can actually perform a legitimate review of a PSU.

ten how about i pay for shipping to a fellow ocn member with the hardware... i will do that just to see how bad it really is... that is IF i get to look at Monday, and IF it turns out to be a piece of junk, although.... being from 2007, and being from the place it is from... i will not hope for too much...

Yeah you'll need an oscilloscope for starters, and then some heavy duty resistors to act as the load. Retail oscilloscopes are from $1,000-$10,000.

So good luck with that! Pictures would still be a bonus. Sorry, I'm just a selfish bastard...sigh.

I don't think anyone really has a full O-scope setup here. Maybe some of the older members who actually might have some money and might be electrical engineers....otherwise, the garbage can looks nice.

Oh and just incase you were wondering, my avatar is a drawing of an O-scope. That's how much I want one.

my high school has 13-14 of those things, i used one in a electrical engineering class there i learned all about ohms, resisters, P I E and R, how to test voltages, i believe ripple was mentioned quite a lot, as well as peek and min voltage, heck, 90% of the time in that class was spent measuring voltage, playing with resistors(we had some heavy duty ones too) and looking at the waves on the oscilloscope, i asked a lot of questions, and there was time spent on waves as well, there was a soldering part too, which is why i got a D in that class, soldering makes me speepy, i can't pay good attention when i am sleepy

wait a minute..... there was only 1 full o-scope there, i can't remember what the smaller ones were but they had waves as well

I used to have a couple of Oscilloscopes back in the 60's and early 70's. I wish I had kept the smaller one, but it's way too late now. And having a scope without the huge resistors needed to put the psu under a regulated load doesn't do you a darn bit of good.
