2003 Power Supply Roundup Part II: Better Faster Cheaper

We talked to Enhance a few months ago with thoughts about where PSU technology is headed. A unique thing about Enhance is that they are one of Intel’s closest development partners, so they always have a plethora of information on hand. Enhance’s web site has a lot of whitepapers and good information to use when researching a power supply that good for you, even if its not produced by Enhance.
The ENS-0246 comes with very few frills. The cable is not shielded or sheathed, but does come in a variety of connectors. Enhance is a very OEM oriented provider, so many of its power supplies have variations on the pin configuration (for different motherboards). For example, the B version of this power supply has 24 pin ATX while the A and C version have 20 pin ATX cables.

The ENS-0246 460W power supply has a combined power rating of 220W. The +12V rail is capable of another 180W which leaves this power supply well shy of the advertised 460W. Our guess is that it is this supply is labeled by its peak power output rather than the actual.
On the other hand, we do commend Enhance for keeping the combined rail very close to the theoretical limit of where it should be. It’s unfortunate that the +12V rail was not a little bit higher, otherwise this would have been a very well rounded power supply.
For a 460W unit, the ENS-0246 is moderately priced around $85. Unfortunately, this is not a 460W power supply, since 460W seems to be more of its peak rating. More features or higher specifications might have given it the edge.

I cast another vote for us to be able to get a copy of the modified version of memtest86. I'd love to check to find out how much bit-flipping is happening over time on my various PCs. In addition, it seems to me that it would be a good way to see if ECC memory is actually doing what it should be. (If a bit gets flipped on a board with ECC memory that's supposed to support ECC memory then there's obviously something wrong).Also, you should give a copy of your modified source to the memtest people so that they might include the long delay time as an option in a new version.

Any chance of a review of the silentmaxx fanless 350W. This thing has no fans so in theory it should be 0Dba! Not sure where the poewsupply is up to the job though on the poewer front - a review owuld be great. Cost as you probably guess is on the high side...http://www.silentmaxx.net/silent_products/power_su...

To me the most interesting data from this roundup was the instability a PS can cause to a system. I think this subject is worth a dedicated article. Also how can we reproduce this data at home? Where can we get the modified memtest86?Anonymous User - Wednesday, August 13, 2003 - link
Hello!!??? Seasonic power supplies?? These have to be the quiestest power suplies I have ever (NOT) heard. Appears to be pretty well constructed. These should realy be included in any decent, comprehensive power supply round-up.Anonymous User - Monday, August 11, 2003 - link
They didn't look at the seasonic brand. recommended herehttp://www.silentpcreview.com/modules.php?op=modlo...

I got a PC P&C Silencer 300 a while back, and I was very unimpressed with its noise level. It was hardly quieter than the cheapo PSU it replaced. My Enermax 365 and Antec Truepower 350 are much better.How about reviewing Seasonic? I hear they're super quiet. A little hard to find, though...

Untill all power supply manufacturers get it together and sheath their cables, we are pretty much stuck with what they offer. I solved this in my window case with some electrical conduit from the auto parts store. there are a few color choices including your basic black, but any of them make a world of difference hiding those unsightly P.S. cables. That and a little electrical tape over the white connector and they almost disappear.Anonymous User - Monday, August 11, 2003 - link
Another extremely happy user with a PCP&C Silencer power supply. I do have to question just a bit why the reviewer didn't find out about their existence on his own, noise being the primary complaint in his review (though I imagine the sheer number of power supplies being reviewed and perhaps deadline pressure could have been factors).Anonymous User - Sunday, August 10, 2003 - link
This is actually the third power supply review on Anandtech. Not the second as you wrote.Anonymous User - Thursday, August 7, 2003 - link
