First 939 MB build - need Power Supply help

[wanderer27]

Which of these would be the best recommendation for a new 939 based System?

Antec True Power 430w
Antec Smart Power 2 500w
Enermax EG465P-VE
Enermax Whisper II EG465P-VE
OCZ Modstream OCZ45012U

I'm still confused on the Dual rail PSUs. Are there seperate/special connectors for each rail ?
My concern is if there's not (seperate/special), then I'd most likely end up tagging everything to just one rail and have problems as a result.

Thanks for any help on this.

 

[Mrvile]

It actually depends most on the video card you'll be using. Anyway out of those I'd probably get one of the Enermax's...I have the Whisper one you mentioned and I love it

 

[wanderer27]

I'm looking at the 6800GT, 7800GTX, or r520/r580 (if they ever come out).

Motherboard not decided yet. Looking at ASUS A8N Premium (to get away from fan problem), MSI neo4, or DFI (this is very iffy).

 

[Safeway]

DFI is the choice of overclockers.

Yeah, I know

I'm not sure how much OCing I'll be doing. The DFI BIOS sounds kind of daunting, and a bit dangerous. Not sure I want to take the chance of frying my CPU, that's one of the drawbacks I'm seeing for this board right now. The other is price

I like the Neopower 480w myself. It has nice cable control, because the ones you don't use can be unplugged from the power supply. Plus the thing is silent.

 

[wanderer27]

The Neo looks okay. But it's a Dual rail, and like I said, I have some concerns about Dual rail.

Also, for $100+ I've seen some PSUs that look more attractive. The ones I've listed are in the $50-80 range.

I really hate paying an outrageous price for a PSU. Yes, I know they're probably one of the most important parts of the System, but there are a lot a decent PSUs out there for less.

I'm going to be paying more for a Video Card than I really want to. But I'm going to need the Power for "Future Proofing". I don't want to
get out of control on this build or the wife will choke me

first off, dual rails are just as good (and theoretically better) then single rails, and no, you dont have seperate connections for each rail, it hooks up like a regular power supply

second, dont spend less on a cheaper power supply, youll regret it when you have to buy a new one in a month or two. trust me.

 

[Operandi]

Dual 12V rails is part of the ATX 2.0 spec, it's the future so get used to it.

Seasonic gets my vote.

Be safe and get one of these:

They're a bit pricier ($90-$100) but as Jesus (lol) said, you'll regret cheaping out in a few months. All the above PSU's are extremely solid and reliable.

 

[Banzai042]

Persionally i'm running the 520 watt version of the OCZ powerstream, and i can tell you that this thing is rock solid, that said though: in the most recent Max PC PSU roundup the antec neo had the most accurate voltage and the best response to voltage sag from the outlet, keeping all voltages at pretty much normal levels, and was overall the most reliable PSU they had. The second best PSU that they had was the PC power and cooling 510.
While i love my OCZ powerstream the one concern that exists is that there is no automatic voltage correction. All voltage adjustment is manual, which is great if you want extra power to your comp, but if the wall outlet has a voltage sag it will hit the comp harder than a PSU with automatic voltage correction (read, every other high end PSU without the manual adjustment).

damn i think i need a 24pin PSU for DFI LanParty Ultra-D board. =(

actually Umm YES and No!!

ATX 2.0.....YES

Near future......Umm no......Umm maybe never.....

From what I understand Dual 12v is NOT absolutely 100% the wave of the future.
Thats just speculation!
Single 12c PSU`s will be around for a long time!!

 

[JEDIYoda]

I am also running the 520 watt version of the OCZ powerstream!!
Very good PSU!!!

First mistake, dont believe reviews in magazines anymore........ i know the neo is a greta PSU, but when every other review out there (ie, the internet) says that the PC Power and Cooling is the best when it comes to the amps on the rails, ill take thier words for it, not Max PC

 

[vanvock]

I've got the PCP&C 510 & feel it's worth the price paid. During a recent power lag bad enough to shut down everything in the house I didn't even know it happened until my wife said her pc had shut off.

 

[wanderer27]

Okay, so if the Dual rail PSUs plug in just like Single rails, are they drawing power from both rails at the same time ? Where's the seperation ?

Also I've read some threads here of people having problems with Dual rail PSUs not providing enough/adequate power. I think one of the guys even had a Neo 480.

As for voltage sags, I've got that covered as I'm running through a UPS with 30min backup - provides a little filtering too

This test they're running over on T's Hardware is not helping much either. They've got quite a few good brand PSUs dying/failing specs.

Building this 939 System is realing proving to be a challenge. I'm having difficulty narrowing down product selection in quite a few areas. It's not because there's a large selection of great products either, it's more of which has the least problems

First off, stop going to tomshardware, just stop. it wont help your decision, as any review they do is likely to be flawed (they put down the OCZ powerstream for having been sent a defective unit, they didnt even try to get a new unit and retest..........)

second, DUAL RAILS ARE JUST AS GOOD AS SINGLE RAILS. Like i said, they hook up like a normal power supply, and youll never be able to tell its a dual rail, there nothing (cosmetic) different about dual rail power supplies.
The power supply itself supplies the amps to each rail where they are needed.


Here, ill make it as easy for you as it was for someone else i helped out.

Look at either Seasonic, Antec, Enermax, PC Power and Cooling, or an ePower Tagan (that exact model) and youll be set. It doesnt matter what model you get of those, no matter what it will be more then enough power supply for your system. Period

 

[DoobieOnline]

Hard to go wrong with the Tagan 480W U22 for $83 shipped. You're able to switch between single and dual 12V rails if that's a concern. This is a very high quality unit!

Check out the reviews here and here. I have the older 480W U01 model and love it.

 

[wanderer27]

Okay, I've looked around and I've done some more research. Right now I'm looking at getting an Enermax EG495P-VE-SFMA Noisetaker for about $83.

http://www.zipzoomfly.com/jsp/ProductDetail.jsp?ProductCode=270323

It's a Dual rail with 18A on each rail.

Anyone have any experience/opinions on this one ?

 

[Diasper]

Seasonic, Enermax or Tagan I'd say.

Although over in the UK when the choice is between Enermax and Tagan, my favourite is Tagan especially given it being single rail, fan placement for P180 and 3yr warranty.

The 530W unit with 32A on +12V and 48A on +5v is nice for you all your future needs.

 

[coomar]

i have the Enermax EG495P-VE-SFMA Noisetaker, it works fine with my dfi nf4, while software reads as struggling, with a multimeter under prime i get 3.33, 5.05 and 12.2V, the fans reduce cpu temp as well

Struggling ? You mean 480w really isn't adequate to run this System ?

I believe he is referring to how inaccurate the software can be at reading voltages.

His multimeter readings are showing good, strong lines whereas the 'struggling' comment I believe refers to the software readout, showing the voltages to be lower.

I just got it. While I'm not running a system anywhere near enough to stress it, the build quality is amazing, it's near-silent (quieter than my old Fortron), is so efficient that the air coming out the back is cold, and just generally kicks arse. The connectors are much better, too... it's nice to not feel I'm about to tear my motherboard apart when I need to unplug the ATX connector. Same with the molexes. And the 20/24 pin thing is handled perfectly.

That's hilarious, I get almost those exact voltages with my motherboard sensor How's that for consistency? God I love this PSU.
