It's dying
« on: February 01, 2008, 01:17:09 AM »
My Antec TruPower 430w is going the way of the Do-Do. All the voltages are bouncing around like a heart monitor. Including the Vcore, which suddenly started bouncing from 1.68 to 1.624 (dangerously low). Want the kicker? The A7N8X-e Mobo I own won't let a 20+4 pin p/s connector fit; there isn't enough room. I've got a copper coiled hoop right up against it on one side, and the IDE plug on the other.

After spending quite a while on NewEgg, I can't find any PSU with an older type 20-pin mobo plug on it. And with the voltages varying so much (5v exceeds 4% variance) I want to get it replaced ASAP.


Anyone know of a power supply still made with a 20-pin plug that I can trust?

Thanks in advance,

I used to have a few laying around, but threw the out, not sure why.

Most everything nowadays is 24 pins.  However, I don't think you'll have a hard time finding a power supply to work.  A lot of power supplies actually say 20/+4 pin.  Basically it has the 20 pin connector with an additional 4 pin detachable plug if case you needed a 24 pin.

Or if you can't find one, they do make 24 to 20 pin converters.

I'll take a look on newegg right now.

Yeah I didn't have a hard time finding a power supply that would work.  I found a 450 watt  Corsair PSU ( I believe Seasonic makes them for Corsair) so its a quality PSU.

It states it has a 20+4pin.  So just in my post above, it will work for you.

$79.99

Notice on the right of this image that those last 4 pins look detachable?  They are.  MY PSU is the exact same way.

Here's the website:

My old power supply had what I and Fulmar aka Mrbucket thought was a short in my PS due to my constant Blue Screen of Death, so I called up Gateway to send a replacement seeing that it was under warranty.

But I would go w/ Fulmar's suggestion.  NewEgg.com rocks!!

I put a Thermaltake 750w PS in my NewEgg shopping cart yesterday. It was, I believe, $175 with a $50 rebate. Today it changed to $185 with free shipping, UH!

It's back out of the cart.

Now I don't know what to do about the power supply. I was very happy with the Thermaltake yesterday.

Fulmar, thanks for tracking down that Corsair. I was reading a few reviews on NewEgg for it and came across a comment about Corsair not supporting ATX 2.0 systems. My mobo pre-dates that spec, and I know ATX 2.2 has a different wiring scheme for the mobo plug. Unfortunately I can't find a wiring diagram for the 450VX to compare it with my mobo's ATX plug. The last thing I want to do is bag a new P/S only to find out the wiring and my mobo aren't compatible. I did shoot Corsair a quick e-mail about this; waiting on a response now.


Thanks again!

I used that power supply as example.  I figured you didn't have SATA drives thus you wouldn't need a power supply with SATA power connectors.  I was showing you that PSU's (many) have a 20+4 pin connector as shown in that picture.  You'll want to pick out a PSU that has molex 4 pin power connectors for your HD's and CD Drives etc.

Molex plugs aren't my primary concern; the lack of a -5v wire on the ATX motherboard plug is. I do know my Antec TruPower 430w does have a -5v line, and the BIOS does report it. I also know, however, that ATX12V v2.2 doesn't have a -5v line on the ATX motherboard plug. What I'm not sure about is whether or not my motherboard (or anything else) needs a -5v line to operate. If nothing needs it, I can replace the Antec right now.

Where's the Skuzzmeister when you need him?

I just double-checked, and the BIOS does not report my -5v voltage. My other voltage numbers in the BIOS (+5, +12, Vcore) pretty much match what Asus Probe reports. Including a rare Vcore bounce all the way up to 1.696 (!!). My Barton-cored XP3000+ is only supposed to draw 1.65 give or take a hair.

-5V hasn't been in use in a LONG time (I think its been over 10 years and Intel was the main company that used it).  And when it was in use, it was a rarity if I recall.  I have a little power supply tester that you can plug molex or 20/24 pin cables into and it will tell you if its good or not.  It still lists -5V on the LED readout and will show you a fail on the cable line, but it does not exist.
