Except for the specifications, the EG651P was very similar to the EG465.  It came with the same glossy finish, copper sheathed ATX cable, and rear variable fan controller.

Undoubtedly, Enermax has the best power supply cable management capabilities available.  To combat interference, the ATX and +12V cables are copper meshed with rubber sheathing.  This copper shielding extends all the way into the power supply housing, where the rails are also shielded in copper.  It is no wonder why this power supply is also one of the heaviest.

This is the only other power supply in our review to display the ATX12V 1.2 compliance. For those of you not familiar, this is the published standard that assures stability with Intel and AMD systems. This particular standard makes sure the +3.3V rail is not neglected when increasing the wattage on the +12V rail, but also assures tight specifications on the lesser used -5VSB rail. We can see that the specifications on this unit are not skewed only to the +12V rail, so this unit does make sense for an AMD system builder as well.

Specifications alone speak volumes for this power supply.  The +12V rail has an advertised rating of 36A, or 432 watts.  This puts the EG651 way above any other non-Enermax component.  However, since mathematically the power supply can only sustain about 330watts on that rail, the advertised 432 is probably the peak output.  Even at 330W, the EG651 still towers over most power supplies. 

The EG651P-VE is one of the pricier units in our round up.  Most online retailers are carrying this unit for around $135, but with rebates and deals you might get it as low as $120.

We thank MaxPoint for rushing us the two Enermax power supplies to us before the deadline for this article.

    Dopey:

    It's an extremely old article. Nobody reads those except when they need to be pulled out of the vault.

    Sad to see no comments since 2003! ???
    Looking for a good power supply for AMD and review indicates that both Fortron & Zalman are good at not too high price. But looking at Antec True Power 330W I read "beware of the extremely modest +12V rail. If you are running a high end video card, or an Intel Pentium 4, this power supply simply will not produce enough juice." Both the Fortron &n Zalman deliver just 180 watts on the +12V rail while the Antec True Power 330W puts out 204 watts. And if you look at the whole list of PSUs reviewed 204 watts looks like a respecatable amount of power. So ... ????????????????????

    I bought the Zalman 300w for $50 as a result of this article. Love it to death, but newegg stopped carrying it.

    1) What size fan is in the Fotron reviewed here, 120mm or 80mm?

    2) What is the model number of the 300w alternative to the Fortron FSP400-60PFN?

    3) Isn't the Sparkle FSP350-60PN reviewed here also a fotron, and what is the model number of its 300w alternative?

    You state for those PSU's that have good amoubt of voltage for the 3,3V are good for AMD.

    It will also be nice to say that most new motherboard from AMD are now using 12 RAIL e.g. 8RDA3+ many more and from what ive seen all K8 mobos use 12 RAIL

    all in all good review.

    What i have found with my TT320W that when you stress it too much and it heats up it will shit down whole system.

    Also if your PC is off for many hours if you touch the PSU its worm :S

    Ordered my Antec 550W True Control

    Also you should show how to short the old PSU so user can use 2 PSU in one system..

    I run my whole system on a 480W ProSourse untill my 550W Antec TC is here

    My GFFX5900 runs on a dedicated PSU 300W soon it will have a dedicated 480 ProSource :D

    And all my 12 fans run on a 300W generic PSU

    Also TT's seem not to like when to many devices are connected to it

    To know how much the exhaust air will heat a room you have to know not only its temperature but also its volume. It would be simpler to measure the efficiency of the supply.

    The tests were not very thorough at all because if they were they would have included electrical noise and current measurements and testing at full power.

    The memory errors could be due to bad filtering more than cable shielding. Putting a 'scope on the outputs would would provide a graphic portrayal of output quality. <hint, hint> :-)

    I enjoyed reading the article and I think it was very well written and the tests were very thorough. Although the article discusses "heat" and examines each power supply to see how well they deal with the heat issue, I think from a consumers point of view, you should have measured the difference in the temperature of the exhaust that is emitted from the power supply. For me that is a real issue as the heat that emits from my existing power supply probably raises the room temperature by 7 to 8 degress (to the point of making it uncomforable to stay in the room on a hot day). I want a power supply that doesn't blow out hot air. Which one of these blows the coolest air? Reply

    As much care was taken in creating the title as in testing the power supplies.

    I hope to see another Anandtech power supply review soon, only one with proper testing. I have to give Anandtech an A for effort in this case, but I can't still give them a passing grade. Please consult with a specialist in this field for any future test.

    Is it just me or does the article title seems a little off? "2003 Power Supply Roundup Part II: Better Faster Cheaper" Faster? A faster P/S? Reply
