[World's First] A quick look at FSP Aurum CM 750 80+ Gold bryanwu May 1st, 11, 09:17 PM #1

A quick look at the FSP Aurum 750 Modular 80+ Gold unit.
(I think its a world's first)

FSP's new Aurum series have brought 80+ Gold down to mainstream prices. The modular series dubbed Aurum CM are supposedly releasing in June.


The Aurum Cable Management series comes in a much bigger retail box than the non
modular series. Everything is well protected by the layered cardboard packaging.
"Play Time" doesn't seem like the most suitable thing for a PSU. Maybe only for me. :s13:


What you get inside: The PSU, modular cables, velcro ties, black
thumb screws, fsp badge and a manual. Instead of a bag, FSP's provided 2 boxes
for you to keep your unused modular cables. A Spring Singapore SAFETY MARK
approved power cable is also included.


The PSU has grown a bit in length. 16cm now instead of 14cm for the non modular
unit. The paint is still finished in smudge free rough black paint. Standard 24pin,
8pin & 4+4pin included. 2 of the 4 pci-e 6+2pin cables are also hardwired.


The exhaust vents are still the arrow shaped type that FSP claims would improve
airflow. As long as its solid and doesn't impede airflow, its good enough for me.
Technical specifications on paper look good. 720w on quad 12v rails.
Also, the +5Vsb is stronger than most at 3.5
The distribution is also good, so no worries about uneven rails.
This unit is also safety approved by a variety of agencies - CB, UL, FCC etc.


Internally, its the same advanced Active Clamp Forward design that's used on the
Aurum 400-700w non modular. The fan also the same FDB one from Protechnic.
You can check out various professional reviews below
Vr-zone |Hardwaresecrets |ZOL.com.cn |ITOCP |PCPoP |


FSP's improved on their secondary filtering capacitor choices.
The Capxon KF series are replaced by Nippon Chemicon KZE series.
In terms of lifespan, they're rated the same 5000hrs at 105degC.
But the KZE have slightly better electrical specifications that should
further reduce ripple values.


Some of you might have noticed from the first few pictures that the modular
cables on the Aurum are slightly different from normal ones.
Instead of weaved sleeving, FSP's opted to use a solid rubber/plastic material to
cover the cables. My guess is that this type of sleeving is more resistant to fraying than the normal types.
Also, flexibility still seems very good.

The Aurum Cable Management Series is a small evolution from the standard Aurum.
Comparatively, you get
1) full Japanese capacitors
2) Modular interface
3) 50w higher capacity (Aurum CM comes in 550/650/750w)

Usually a modular interface costs about $20 more. (Seasonic S12II620 to M12II620)
Hopefully, the extra JP caps and 50w wouldn't increase the price much more.

Thanks for reading!

i also don't know how much it'll be..

This unit barely misses 80plus platinum rating of 90/92/88.
Its 80plus report states 90.88/91.27/87.88.
http://www.plugloadsolutions.com/psu...50W_Report.pdf

I know some of you don't think 80plus is a good gauge of quality.
Because it simply isn't. Its just a gauge of efficiency.
But with more advanced designs, quality is usually improved too.

And you guys can check out this cost calculator
PSU Secrets

The default example shows that by using a $95 400w 80+ Gold unit over a $65 75% eff unit, at 12hrs 150w, you'll save about $40 from elec bills a year. In the long run it might just be more worth it to get a high efficiency unit.

this unit quite light, compares with seasonic 750w with FSP 700w .

yeah fsp came up with this new design and managed minimise the components used

and weight isn't a good gauge of quality these days

just wondering how come the interior so few heatsinks...

fancy new design = higher efficiency = less heat produced = less heat to expel
few components = smoother airflow too

the 12v and 5v are generated through synchronous rectification
the 3.3v VRM are placed on the bottom of the PCB and is derived
DC-DC via the 5v rail

most of the reviews pointed to FSP using their inhouse designed integrated controllers
FSP6600 and FSP 6601. Probably allowed them reduce unnecessary components to improve efficiency.

on seasonic X there's actually a similar design..
the primary switches are on bigger heatsinks while the secondary 12v switches are on thin heatsinks as they're highly efficient.

same for the fsp unit just that instead of 6mosfets on the seasonic, fsp decided to use 2 more powerful and probably more costly mosfets to generate the 12v

Aiya my bro just hooted the FSP 500 gold .. is dammg good. I quite like the built. I fixed up for him.


Have to thanks BryanWu for the heads up!!

i just hooted the 500 yesterday too... the interior is just too deliciously simple.

Mr. Wu, would you say we would have similar efficiencies with this, or is the new CM series ever so slightly better?

YUP... actually I quite like both Seasonic and FSP designs.

Very well done for both ^^

Regards

I do believe the efficiences is almost the same ^^ since not much changes!! Plus both are GOLD^^

aurum non mod and modular version should feature very similar efficiency levels according to the 80+ tests
Ecos Plug Load Solutions
the main differences should be full jp caps, modular and 50w more..

but the platform as a whole seems to have pretty good low load efficiencies..
based on 80plus.org's tests, at 20% load the 500-750w units all feature almost 90% efficiency.. quite a bit higher than the 87% minimum that's required.
