Enermax voltages

I meant to get the enermax w/ 5v+ protection, but I seemed to have bought the wrong one...

Anyway, it's a 350w, and my 5v line is running at about 4.75-4.85...

I know this can't be good.... look at "My troublesome rig" for specs, what could be downing my 5v line so much? I also have a single 80mm exhaust fan, sunon... Dunno if it's even a 5v one... and a small 40mm fan on my northbridge. But I'm sure those can't be dragging my line down so much.

So, how about a little help?

Also, my t-bird's temperature gets to 51*C under --full-- load, stressing full. Is that alright? (It's a 266fsb 1200mhz) I have some friends running their t-birds idle at more than that, so I think I'm ok....

5V is typically speced to +/-5% you are in spec. I would bet that if you used a quality voltmeter to measure the 5V that it would be right on the money. There is more likely an error in your sensors then the voltage. If you are not having any problems don't sweat it.

The higher your CPU, the lower yoru 5V will drop. This is a limiation of motherboards, and NOT your PSU (well assuming you have a good CPU).

There is a mod - run a line from your PSU 5V line to your mobo (to a certain mosfet, not sure which one), it will boost your 5V line to 5.00 or higher, proving your PSU has the juice, but your board is not distributing enough of it.

When I go up to 1400mhz, my 5v line drops to like 4.6-4.68... It did that with my crappy DEER 300w PSU, that's why I even bothered to get a Enermax! But it still does it :( My computer isn't stable @ 1400 when running 3dmark2001 and some other 3D stuff, some.

This is not quite accurate. The reason the 5.0V line drops (droops) is because there was an increase in load. The voltage droop is not a limitation of the mobo but rather the regulation of the PSU. Try placing a PSU with high 3.0V + 5.0V wattage (Sparkle's are the best when it comes to this) and try another with a lower wattage you'll notice your 5.0 droops more with the PSU of lower wattage. Enermax are good only because thay have quiet fans but when it comes to regulation and wattage (+3.0V and +5.0V) Sparkle's does it better.

Well, I thought there was a model of the Enermax's that give more to the 5v line... And like, every person I've ever talked to said Enermax was the best... grr...

Think someone would trade my enermax for a sparkle? Are you 100% sure my 5v line would increase? Cuz if I don't have a 100% re-assurance that my 5v line will increase, I won't buy it...


But other than overclocking I have zero problems with my computer now! (with the deer I had restarting/shutdown/boot problems)

There is still the problem of my cdrw not working at boot sometimes, but that's not a PSU problem, as it did it with 3 different PSU's, and it's not THAT common, so I don't worry about it...

Under high OCs your 5V line will drop, I dont care what PSU you have.

However, you are correct in that at lower speeds Sparkles have a higher 5v line, that is why many people take sparkle over enermax (just not many on this forum).

I don't think that 1.2 is high enough to be totally limited by his mobo, and I did not mean to imply that. But it is high enough that because of the way motherboards regulate their power, he is going to have a 5V drop of some sort no matter what. With a sparkle, it would be less.

my 350w enermax sits around 4.88v at idle with my 1.4GHz (not overclocked) and 4.83v under load. If your machine is stable, then you don't have to worry about it.

Budman -

That's wierd... a 300w is rated for the 1200mhz..but not the 350w??

My psu isn't on the list at all... the EG365P-VE, hmm...

Tell me about it, i am so pissed too.

I sold my Aopen power supply &amp; got this Enermax EG351P-VE because i wanted more power,as it turns out my old Aopen PSU that came with my HX08 case is rated good up to 1.4ghz and this one is only rate ok for up to 950mhz. :(

After sticking in 2 more pci cards into my computer and now running with all 5 pci slots filled, my +5v dropped from a steady 4.85v to 4.76v, sometimes going as low as 4.73v. I'm also using an Enermax, 350W model. I might try out a Sparkle as a previous poster suggested.

They updated the old Aopen PSU on Amd's site to a 1.4ghz, so i guess my newer but crappier Enermax is only aproved to 950.:(

Now i only have to call up the guy to whom i sold my old psu unit to see if he wants to trade.

Hello it's me,
Hi what's up?
About that psu i sold you,do you want to trade for an even bigger one for free?,
What's wrong with it?
Nothing i just miss the old one
Yeah right buddy,cya. :(

you try out the sparkle and tell me how it goes :) You wouldn't happen to be running a 1200t-bird/kk266 would you?


I took out my Promise Ultra 66, just using motherboard for my hard drive right now....

Budman - LoWlZ

I might see about trading for someone's 300w sparkle.. dunno what to say when they say &quot;WHY?!&quot; :(

I've got a reading of 5.03v on my +5v. I bet it's accurate too. I have a very good 400watt psu(not sure what it is exactly, but it does have a good dual fan setup and the case is chrome). My mobo is an Abit KT7A. I bet that a better PSU would do the trick. I've never had any hardware-related instability. I'd go with a better psu, just because of the fact that it WILL increase hardware stability(unless if your system is already 100% stable).

P.S. Don't skimp on wattage!!!!!

Budman: you have an older version. I have a 365P-VE which is a newer version. It is AMD approved, just not listed on their website. It runs my 1.4GHz just fine. I don't know which version DonNiggera has

I have the same version, bought it retail...EG365P-VE... I wonder why it runs your 1.4 better than my 1.2 though :( Is yours a 200fsb or 266fsb?

hmm... I hate my computer! I only have one bad object, the hard drive, 4gb piece of trash replacement for my Quantum Fireball that went dead.... I doubt that's dragging my 5v line down though...


What would help more - Using hard drive on Promise Ultra 66, or using hard drive from the motherboard?

I found my PSU on the list:

Fortron/Source FSP400-60GN 400Watt, approved for athlons up to 1.4ghz.

I had a Sparkle PSU which game me 4.65v on the 5.0v line so I bought an Enermax. Didn't change help one bit although my computer was never unstable.
