New "Liberty" 620W from ENERMAX

[Dave in Daytona]

Watch it people, lets not allow this to become a flame fest.
Dave in Daytona, you are pushing it, keep it up and you will receive an official warning.

IFMU

Is that a threat?

[IFMU]

Is that a threat?

No, it's a promise.

[Jupiler]

Picked up this one today :


























I will be testing it this weekend and post some results.

[Dave in Daytona]

CONGRATS!
A beautiful PSU!

[Jupiler]

It looks nice indeed, hope it performs the same way.

One little thing I find weird is how the cables are managed.
There are 8x 4pin connectors and 8x SATA connectors in total, divided over 4 cables.
Now, logically, you would expect that you'd have 4x 4pin molex per cable and 4 SATA connectors per other cable, right? That's what I'd expect anyway.
But no, you have 2x 4pin and 2x SATA on each cable. Don't really understand why they did this. If you have 4 SATA drives in your rig, you'll be needing 2 cables instead of just 1, if there were 4x SATA connectors on it.

To balance the load over 2 cables, instead of one.

Very nice write a little review if you can.

[nn_step]

So you will not buy any component based upon 1 failed psu in 1 review? That's not very logical, IMO. And Enermax has a stellar reputation for building high quality psu's.

Lovely but I never heard of a PCP&C PSU dying in any review/test what so ever...
I spend too much money on my rig to risk it with a "most likely" good PSU
I demand perfection from my PSU and Enermax has yet to meet my requirements...

[Jupiler]

OK,
installed the PSU in my other rig, consisting of the ASUS P5WD2 Premium and a 630 @ 4150Mhz.
Powered up and checking the voltages in the bios.
+3.3V : 3.39V
+12V : 12.19V
+5V : 5.17V

Not bad for a start.
Had to make a fresh install of XP. After that, I tried getting MBM reading the voltages, because the high/low feature is good to record and check the average voltages.
Unfortunately, I couldn't get it to work, neither had speedfan the option to record it, because it could only read the +3.3V and +12V lines.

So I had to do it with ASUS Probe II. Couldn't find any recording features though, something the older version has.
I had 2 instances of D2OL running, and while it was running I observed the lines.
Probe II recorded the same voltages as the bios showed at startup.

The 3.3V line stayed at 3.39V and didn't move for over 5 minutes.
The 12V line fluctuated between 12.17 - 12.20V, didn't see it go higher or lower.
The 5V fluctuated also a little between 5.17 - 5.20V.

To bad I couldn't find a better monitoring program, which would make it easier to check the voltages.

About the 12cm fan :
it spins at around 1000 rpm and is very quiet.
I turned off my system fans and had only the cpu fan from the TT Big Typhoon running, which is known for being very quiet too.
Well, I couldn't hear the PSU fan from close range, the TT fan was louder than it.

To make a more accurate test, I'll be swapping PSU's tomorrow and try the Liberty on my DFI SLI-D. MBM works fine on that one, and it will give me the possibility to compare it against my Powerstream 520W.

I hope to get more results by monday.

[Dave in Daytona]

Walmart has very nice B&D DMM's for about $15.

[Jupiler]

I have a DMM thx, no need for me to go across the atlantic to find a Walmart.

Took out the MM and measured the 12V and 5V lines.

Under load :
12V : 12.06-12.08V
5V : 5.13V (didn't move, stayed the same all the time)

Nice, steady voltages if you ask me.
Don't know if further measurements on another board are required. If yes, just ask.

Looks good to me!

Thanks for the info Jupiler

Could you give us a reading on the 3.3 's stability on the MM ?

Depending on how efficient it really is it's goona be my next PSU since the Seasonics have some minore issues with the DFI nF4.

Hopfully SPCR will do a review of it,they have an excellent testing rig.

[perkam]

JP, are the load results with your SLI rig ?

Not too surprised with the 5v and 3.3v rails as Enermax has done the same thing Seasonic does just to give insane wattage and amps to its 12v rails ---> Skimp on wattage for its 5v and 3.3v rails (total power 160W, total power for Seasonic 600W for those two rails is 180W).

[Jupiler]

I'll check the 3.3V line later today.

[Jupiler]

Nope.
Results were measured with just 1x 6600GT in my rig.

I was assembling a rig for a friend of mine (which included the same card as mine), so I took the opportunity to put them in SLI and ran some benchmarks.

[shocktech]

If Voodoopc uses it and insures it.. its gotta be good and reliable.

[Jupiler]

Here's a pic from the 3.3V readings on the MM.
Measuring was done while dual prime was running for about 10 minutes.
3.3V line stayed at 3.41-3.42V all the time, didn't go any lower nor higher.

Keep in mind that I tested this on the P5WD2 Premium board, no tests were done on the DFI NF4 board. Sorry.

To balance the load over 2 cables, instead of one.

Hello, I am from ENERMAX PM in Taiwan. That is wrong. The connectors a a new concept called ETERNITY. They are designed to give you maximum choice in between SATA and Molex. (Up to now Molex and SATA were fixed in numbers.) ETERNITY features these in pairs so you can have maximum SATA or Molex or mixed as you wish without adaptors up to 12, when using spare cable. (1 socket is free)
Therefore they are mixed per cable and not for load reasons or any other.
Additional benefit is that you can exchange Molex HD to SATA HD without any reconnection of other components by just using the SATA connector besides the Molex.

Jupiler, since I understand you are doing a test review. In case of any questions please contact our LA or San Francisco office.

Welcome to Xtremesystems ENERMAX !

Could you please find out why the ferrite ring core of the Noisetaker is not found on the Liberty ? Is it simply not needed ?

[ENERMAX]

The Ring Core is not necessary, due to a new PCB design inside, which minimizes EM pulse.

On sale at the egg. Looks like I know what will be on my x-mas list, though I love my Whisper II 535w.

Hi!
Does this PSU have 8pin connector?
Does it have any issueus running with DFI CF-DR?

[ENERMAX]

Yes,
All our desktop psu's marked with "All-in-One" have an 8 Pin connector or like LIBERTY 4+4 (4 pins are detachable without adaptor). The EPS models anyway :-)

No issue or incompatibilities known with any mobo or graphic card as long as they are ATX12V 1.3 or higher. (No -5V available)
