I have this power supply http://www.newegg.com/app/ViewProductDesc.asp?description=17-163-017&depa=0

All the reviews on it are great. I have been running it in my system for awhile with no problems. But lately I have begun to worry. I dont want to ruin my system. I have a 3200+64 with 1 gig of memory and 3 serial ata drives etc. I dont have the system in front of me but when I look in the bios under the voltages I have noticed like my +12 at like 11. something. Is this normal? Does the voltages fluxuate like that? Or would I be better off ordering something like this? http://www.newegg.com/app/viewProductDesc.asp?description=17-103-444&catalog=23&manufactory=BROWSE

Thanks for all the input...


Here are my voltages from my bios:

vcore- 1.44v
vdimm- 2.64v
+3.3v- 3.28
+5v- 4.99v
+12v- 11.77
-12v- 12.04
-5v- 4.98
+5vsb- 4.91
 
Links are broken

Edit: Bios not the best place to get voltages but they are all within the +/-5% spec.
 
fix those and add your full config including fans and thier size, rpms too if you know em (or thier amp draw as listed on em)
 
:eek: Powmax :eek:

What reviews?

That enermax is a bit weak. Budget? System specs?
 
I bet that 370W Enermax puts out more power than that Powmax.

As for the Powmax, ditch it. It's major POS, and in a likelyhood when it blows, it's going to take more parts with it.
 
i dont like enermax they was supposed to be good but ill stick with antec fow now
 
You think Antec are the best? I say the budget for the power supply is anywhere from 20- 80 for a power supply, I just want something good. I thought Enermax was suppose to be one of the best?
 
Powmax makes the ultra x-connect power supply, and we all know what kind of reputation they have.

They are?? Must have missed those reviews. I've got 300W power supplies that put out stronger, cleaner, more stable power than that Powmax (I have a black w/ red Demon 580W so I'm speaking from experience.)

Your 12V is dropping because you have too much load on it.

That Enermax is a great PSU, but it's 5V heavy. You might not experience the same drop in 12V, but it'll only be a matter of time before it's performance drops from being overworked or it fails you completely on a video card upgrade down the road.

Do yourself a favor and get either a dual rail PSU or something with a 12V at or greater than 18A. DO NOT look at total wattage or I will come over and brand your butt with the soul of my 10.5 Airwalk. ;)

sorry i assumed when i went to the powmax website and they had ultra psu's along with the demon and solution series they were the manufacturer.

Powmax USA is a wholesale channel just like SED or Bell Micro. They couldn't have Leadman MAKE anything better quality than their current line up (the Demon, etc.) so they just tacked the Ultra X-Connect product line onto their website.

It's pissed Ultra off enough to ask them to start putting the "X-Connect power suppllies are made by Ultra Products" disclaimer on all of the pages, but the damage has already been done. Now people are thinking that this power supply and this power supply are the same thing and it's hurting sales because the Powmax is just two 300W power supplies sharing the load like a cheap-version of a typical server redundant power supply whereas the Ultra is actually two seperate power supplies with one doing only the 12V.

I actually had a guy email me and say, "I'm really glad you liked that 600W Ultra because I ran out and bought the 600W Powmax. It was a lot cheaper at Newegg than anywhere else. You really should point out that they're the same thing but without the Ultra badge so it costs a lot less." :eek: :eek: :eek:
 
So give me some recommendations off of Neweggs site that you would buy and I will order one...

rare to see a smoking gun like that
and we may have had something to do with the change in attribution at powmax :p
(there was considerable linking inbetween here and the UltraProducts support forums)

been doing our best to correct the attribution since then
 
Here:

http://www.newegg.com/app/ViewProductDesc.asp?description=17-103-915&depa=0

This Sparkle is "only" a 300W, but it puts out 18A on the 12V rail, so it would probably actually serve you better than most 420 or 480W power supplies out there that tend to only have 16A or less on the 12V. Only $30.25.

Here's another:

http://www.newegg.com/app/ViewProductDesc.asp?description=17-101-513&depa=0

Actually has 28A on the 12V rail. I had one loaded up to 30A for an hour without a whimper. It's based on a Topower XP Series. Ugly flat black finish and stupid glow-in-the-dark Puma sticker on the side, but decent power. ePower/PCMCIS also has the exact same thing in a "gray" version that should cost less (because you're not paying for a glow-in-the-dark Puma) but I don't see it on Newegg's site.

That makes it easy....

Too many to list.

If you're going through Newegg, just stick with the Antecs, ePower, Sparkle or FSP (same company.) I don't have experience with Seasonic, but someone that builds PC's said they had problems with the lower end ones after long term use.

Just find one that LOOKS like something you'd like and then look at the specs. If it has one 12V rail, makes sure it's 18A or more. If it has two 12V rails, you'll be fine no matter what (since that PSU was engineered to run 12V regulated CPU's.)

It's really that easy. Just don't limit your search to "400W or better" because I can list a lot of 300W power supplies that actually perform better than a lot of 500W power supplies! :D

Maybe you just didn't understand. I'll try to be more helpful here.....

Look at this: Output: +3.3V@30A; +5V@32A; +12V@14A; -12V@0.8A; +5VSB@2.5A

Almost all of the power supplies on Newegg's website have this information. 14A on the 12V and 32A on the 5V is like you're going to power a dual Pentium III or something. I'm saying, if you want this power supply to perform well AND last you through a number of upgrades, that number needs to be 18A or higher unless the power supply has two 12V rails (in which case it would say "+12V1" and "+12V2" instead of just "12V".)
 
But I thought if you said it has dual 12v rails it would be alright. That model says it does...
 
I already said no to that enermax aftert the links were fixed last night, maybe this time it will be dropped as an option.

Dual 12v's would be two +12v lines. I know what the text says but it isn't correct it is an ATX1.3.

Enermax IS good. I've had three of them. The first two are in other people's systems right now still working perfectly. The third is in my main box (see sig) and is a few months away from being a year old.

That said, the 370w model the original poster mentioned looks like an early-ATX spec where most of the amperage is on the 5v rail, as it's rated quite high, while the 12v rail is relatively weak at 14A. I'd look at an Enermax with either a high amperage on a single 12v rail (minimum 20A, higher if possible) or a good dual-12v rail model if you want an ATX 2.x compatible supply, with a minimum of 15A on each rail.

EDIT: After reading beyond the post I replied to; What JonnyGURU said.
 
nodle said:
So is it alright then? It shows dual 12v on the box in the pictures also.

IF it really, really is a dual rail... then absolutely.
 
Nodle, here's a good Enermax PSU for just under $80 that will leave you with some room to grow:

http://www.newegg.com/app/ViewProductDesc.asp?description=17-103-459&depa=1

ATX 2.01 compatible, two 12v rails, both at 18A, and good amps on the remaining rails too. Plus you'll get SATA connectors and a PCIe connector as you need them.

If you want a little more style, the Fortron Blue Storm has been rated highly by trustworthy reviewers, for $10 more. It's 12v rails are slightly lower amperage, but its figures are rated a bit conservatively, and it comes fully sleeved with high quality EZ-grip molex connectors that make plugging and unplugging really easy. It's one-fan design will likely make it a little quieter than the Enermax. One note: NewEgg lists it as a 500w PSU likely due to Forton's model number, but it's a 460w; even so, it's a good unit.

P.S. Don't ever go by NewEgg's reviews by buyers. The crowd that gave the Powmax supply high reviews doesn't know much about power supplies, but knows they want bling bling. Even NewEgg has a disclaimer that good reviews there don't necessarily mean a great product.
