    Toms hardware did a stress test

    Rats...can't figure out how to use the insert image button...oh well.

    Anyway Nice review. <Fav'd>
    On Toms Hardware pages you can find a stress test, where the Enermax PSU's do comparatively well....

    Curious that no one tests PSU's at operational temperatures, like commercial and industrial equipment manufacturers do. Get an IR thermometer or a themometer with a probe that can be inserted into the PSU, and see what the actual operating temperature is after being under full load for a while. It's way higher than the 25C that PSU vendors claim (if they claim anything at all) their ratings are measured at. No one seems to dare open their PSU and show the interior next to that of a PC Power & Cooling PSU, or to compare specs with PCP&C. There's a reason PCP&C is always the PSU in Maximum PC's annual Ultimate PC. Interesting that no one other than Maximum PC ever includes it in their "evaluations."

    Enermax Noisetaker EG701AX-VE

    I recently purchased an Enermax Noisetaker EG701AX-VE, after reading the stress test on THG, so am quite interested in the results for this PSU from hexus.net, and why they are different. After some research, it appears there are 2 versions of this PSU. The one tested on THG seems to be the newer one, which is rated for SLI, has a 24 pin motherboard connector, and also includes 2 PCIe connectors.
    I also found this on a review done at http://www.silentpcreview.com/article221-page1.html

    "Our sample is a Noisetaker version 2. The main difference between the Noisetaker revisions appears to be adherence to the newer v2.01 rather than v1.3 of the ATX12V PSU Design Guide. The actual specifications have not changed much for comparable models; according to Enermax's spec sheet, the only differences are a slightly higher rating for one of the 12V rails and the disappearance of a combined maximum wattage for the 3.3V and 5V rails."

    This seems to explain why they weren't able to increase the combined wattage on the 3.3v and 5v lines above 120W, while THG had no problems pulling 600w from this PSU.

    Any ideas? I'm trying to find this out, as I don't want a lot of money wasted on a PSU that can't go over 460w.

    First off pretty good article. Lots of PSU's tested, but as others also mentioned to bad there where no antec's.

    One thing I find very very supprising in this review is that the FSP and Zalman supplies perform so differently. Several sites allready mentioned that the Zalman is simply a relabeld FSP PSU. On opening this becomes clearly visible due to the PCB that has FSP markings on it.

    However things can always be done better : ) And what I really miss was not only ripple analasys (as also mentioned) but inside (+outside) pics (as for example xbit did in their review here X-bit labs . Maybe add the 'weight' of the PSU (as that mostly also is a pretty good indication of built quality).

    I saw a review once that went as far as measuring heatsink thinkness and area. Also very important I do belive! (Bigger heatsinks cost more, if manufactures try to save a few pennies there, what else might they be saving a bit too much on?)

    My favorite PSU (allthough heavly outdated yes) is still Anandtech's

    Notice the memory test they perform. Now you could argue that they have bad ram a bad motherboard or what not. But if you look at the diverse results with different PSU's on the same motherboard +cpu +ram combo, things become rather interesting. This is one of the reason's I looked for a FSP, Fortron, Nexus or Zalman. Since Zalman was the most easy to purchase I got that one and I can only praise it with it's near perfect power low heat and very low noise.

    On an interesting note I was reading Custom PC while on holiday and they did a very similiar psu round up and the results were along the same lines as yours. With some big brands coming out very badly

    Tagan TG480-U01

    'Connectivity is the Tagan's strong point, the latest revision able to power just about anything, including a pair of PCI Express graphics boards'

    When I'm buying one of these how do I know that I'm getting the latest revision with 2xPCI-E connectors (SLI Ready) if they're called the same, TG480-U01? The ones that i have seen on the web seem to only have 1xPCI-E connector and nothing is mentioned that they're compatible with ATX 2.0 and BTX. Shouldn't the product have a different name if it's a later revision? Tagans website doesn't seem to be up to date, you get a bit confused. The only psu that comes close to the one presented in the article is the TG480-U22. Or maybe it's just a typo(s) in the article?

    EXELLENT article btw, nice work, maybe add some more photos next time.

    edit:
    So, I understand now that there is a latest and older revision numbers of this very same PSU model.... so the question is, what revision number is the latest (the one that is SLI Ready and has support for BTX and ATX 2.0) and are they available on the europeing market, if so, under which SKU? How many revisions are there?

    Off to google for some more information.........

    Question Which PSU?

    Hi guys,

    I need help. Big help.

    I've got 5 IDE drives (large capacity collected over the last 2-3 yrs) [5 x molex connectors], a CD Writer [1 x molex connector], a DVD-ROM [1 x molex connector], a DVD Writer [1 x molex connector], a floppy drive-cum-media card reader [1 x floppy connector], a 6800 GT Ultra [1 x molex connector], a Sound Blaster Audigy 2 ZS Pro [1 x floppy connector] and 4 thermally controlled case fans [4 x molex connectors]. It's all hooked to a Gigabyte 7N400L pro motherboard & an AMD Athlon XP 2500 Barton overclocked to 3200.

    Now I've got a 550W Antec Trupower 2.0 PSU trying to run my gig which seems to barely keep the power fed properly to two of my HDDs.
    Now all my HDDs are set on cable select & its the 2 slave ones that seem to be unpowered even though the BIOS can clearly detect & acknowledge their presence during boot up. The CD & DVD drives on RAID IDE connections set yo normal non-raid settings. So they run a-ok.

    Should my Antec 550W PSU suffice me to run 'em all? Or should I "upgrade" to an FSP Epsilon 700W PSU to keep 'em all on the go???
    I could supply u with a better picture if need be...

    Thanks. I'd appreciate all the help I can get bout this cracker...
