Zippy Emacs or Silverstone

[Lucatz]

Having a hard time choosing between a Zippy GSM 600watt at about 150 or a silverstone zeus 750 at about 200. Both are not modular, don't really care for it. I see some people only sware by zippy's, and they seem to be of better quality. My question is since both can do SLI/Crossfire then is the 50 extra bucks worth it? To give you an idea of what my system has:

C2D e6400 @3.2GHz
Corsair XMS2 DDR2-800 *2 512mb @1.9v
Zalman CNPS9700
ATi Radeon 1950XT stock (might overclock once I get better supply)
1 opticle Drive and 2 SATA2 Seagate Baracuda 320 Gigs
ASUS P5W DH Delux
2 Case Fans 120mm

Presently I have an Antec Truepower 2 450 watts which I think is running above 80% capacity thus the reason for more PSU juice...

Thanks for any sugestions :)

Either PSU will do the job. Both of them are at the top of my own list of good units, with Zippy at the very top. I'd go with whichever is cheaper unless you're after silence - IIRC the Silverstone is the quieter of the two.

Zippy and I would get the zippy even if it was the more expensive unit

Zippy gets my vote.

IMAO Zippy is the Holy Grail of PSU's{Right next to Super-Micro,Ablecom,Lite-On} But being as they are server based PSU's.
They seem more at home in a server farm then they do in a desktop PC.
Not saying the Zeus is not server grade Etasis goodness, but is "also" aimed
at the extreme gamer crowd as well.
Zippy does make the gaming line with the home user in mind, but foremost and
most important, the Zippy is "bulletproof" in "all' enviroments;)
If noise is not an issue, Zippy hands down:D

Read what jonny had to say about the fan noise of this unit in question.

Sheesh! These guys think it's an old piston engine aeroplane :p

If you want to keep the main fan's thermal control cool(=fairly quiet operation), using 4 dots of silicone adhesive, bond an 80mm fan at 25~30cfm on the intake grill as close to the harness as possible. This will cool the far side of the secondary side of the PSU, this is where the thermal sensor is.

Ultimate solution for fan noise:

Jaro fans with Sony fluid dynamic bearings:

See that 06mm 15,000rpm .22cfm fan?:eek:

Bet it sounds like a swarm of angry bees with a half dozen of those lil' bastards:p

[Terru]

Where can one grab those fans? They have pretty crazy specs...

Thank you all for your wisdom and great forum...Zippy it is

Great! They offer a 120x38 that puts out 107cfm@41dBA. That's crap!
I have Sanyo Denki 120x38 that put out 102.5cfm@35dBA. That's super good!

Provantage.com has Arctic Cooling fans for cheap that offer decent air flow
with very low dBA. They have ceramic bearings and come in 80, 92 & 120. ;)

:mad: real nice....

Anyhoo... seems that these fans are the same as ADDA (as per AD part number) although these guys claim to own the factory. I think they're lying about that. AD.. first two letters of "ADDA." ???

[GalvanizedYankee]

Sorry :o

ADDA does offer some green labled fans that have thier HyPro sleeved bearings. They are quieter like a good Japanaflo(Panaflo made in Nippon).
Mouser carries the green labled ADDAs, they are expensive.

[jonnyGURU]

I asked my friend in Taiwan. He said Jaro is just a relabel. ADDA is an actual manufacturer with factories.

Bastards! Those Jaro guys claiming that they make their own stuff!

Did find out that the fluid dynamic bearing is a Sony part, though. ;)

im using a enlobal 120mm @ 17dbA in the front of my case, but only 44cfm. magnetic-barometric, no bearings/friction. im wondering if i can lose the front fan all together and just have rear fan pull [2x 60mm, see below]

im getting ready to mod out my HDD sleds with 40mm scythe mini kaze at 14dbA [4.11CFM, hopefully enough for HDD airflow cooling], the ones they put in there are too loud [AGE AFS110, cant find them googling...].. there are two, 1 front/1 rear and when both start going noise is too loud. unfortunately these are plastic sleds and am waiting for the aluminum to come in stock which should help passively.

i have thermaltake 60mm in the rear, which are fairly quiet @ 28dbA, but looking at the vantec stealth at 20dbA.

I've heard there's some QC problems with the magneto fans, though.

When they went into heavy mass production, they couldn't make the fan blades all the exact same weight, so there's reports of wobble and noise.
