500W to 550W: 12 Power Supplies Compared

Comparison: SATA Cable Lengths
SATA connectors continue to increase in prominence in modern systems, since many new hard drives only include SATA power plugs and we are seeing an increasing number of optical drives that utilize SATA connectors. Unfortunately, quite a few power supply companies apparently haven't noticed this trend, and they think that four or five SATA connectors is sufficient. After all, most computers only have one hard drive and one optical drive -- who needs more than that?
This is one case where modular power supplies can be very convenient, particularly if the manufacturer chooses to provide extra harnesses. You could build a system today with more Molex connectors, but in a couple years the only thing using Molex connectors might be your fans, at which point in time you could switch to SATA harnesses. Corsair, Enermax, and Sunbeam only provide four or five SATA connectors, while most of the others provide six.
Tagan is the only company to provide eight SATA plugs, on both of the models we tested today. Tagan also has the longest SATA harnesses, at 90 cm and 95 cm. Arctic Cooling also offers a single connector at 90 cm; however, the single longest SATA harness could become a problem if you have a large case with SATA optical drives at the top and hard drives at the bottom, which is why we prefer multiple SATA harnesses.

thanks a lot for the tip, but after adding shipping costs, this is waaaaaaaaaay above my budget (68 euro)knowom - Friday, February 20, 2009 - link
The XClio STABLEPOWER 500W really should have been included it's a great PSU and very silent it's also relatively inexpensive for the quality especially if you can find one on sale.orionmgomg - Friday, February 20, 2009 - link
How many PSU reviews are you going to do?I know a good PSU is important, but the margins are so close - and for the most part the choice is very simple; OCZ, Cooler Master, Corsair, Ultra, Antec, etc, etc, etc...
Just give people a little list of what to look for, what’s new on the market and what your top 3 recommendations are.
Use the extra energy to dive further into the different i7 platforms, or give us some updates on TOP tier i7 systems with Uber Graphics solutions, we like to see and read about the over the top most powerful computer systems and gaming systems, not yet another review about mediocre low power PSUs...
As always, thanks for the info on the site, and for being one of my favorite tech update daily visits.
We want graphics reviews from YOU. (not the other guys...)
What i want to see is a i7 system OCed to hell running 3 GTX 285s, vs. quad sli (2xGTX295) vs. quad ATI (x24870x2)
Or other insight into the i7, or Geforce 9300/9400 or how much apple and the iphooled suck…

i care, because most of us here can't afford a 3,000+ system, let alone be stupid enough to buy one.i am actually rather sick of these "uber" high platforms and never any midrange stuff like most of us use, what i would actually like to see is a e8400 with a 4870 or gtx260 compared to see what real world performance i will actually get, not some 1,000+ cpu with a 400+ graphics card.

I see - your point is taken. There are other sites that have lots of reviews like this one, another site is fudzilla, guru3d, and toms hardware - but they dont have the same level of inteligence (for the most part) as Anandtech.I imagine if your looking for a mid range PSU, and your on a budget, some of these PSUs recommended here cost almost the same amount as 1000W PSUs... So - I am not sure what to say other than, if I am on a budget, I look for the CHEEPEST PSU that qualifies to my standards... - knowing the standards is more important than micro analizing 500/550 and 600 watt PSUs for their oh so slight differences, and when your on a budget, who really cares, as long as its a quility built and reputable company, bottom line is bottom line... and as I said, some of the "best" mid range PSUs go for the same or little less than quality 1000w PSUs... So - so.
On the other hand, insight as promissed into the i7 platform, more coverage of the multitude of systems as prommised would be nice, though I know its all very time consumming, and repetitive, because just when your done with one major review, an entire new platform is already on its way out! So, it kinda sucks, but thats why we come back and keep reading...

With so many full ATX PSU to choose from and most systems not built for gaming using under 300W, it seems there is still a gap in what many of us need.Which mATX PSU can deliver, since their upper limits tend to be a lot closer to the peak load a system might place on it, and their construction often economized to their price-points not just the available space inside?

ok, so english might not be katzer's native language, but that's what editors are forComparison: PCI-E Cable Lengths - Arctic Cooling is only company to provide >>for<< PCI-E connectors.
> BFG LS-550 manages just 1.5% regulation - poor phrasing, sounds like that's a bad thing
> spend the fans faster -> spin
> which up to keep temperatures in check.
> which were some people is far and away
> pleased to present >>taken<< with our Bronze Editors' Choice award

Speech recognition software sometimes gets it wrong and since Jarred was up all night he just wanted to finish up at some point. We'll make sure to correct it all.JarredWalton - Friday, February 20, 2009 - link
Thanks - I think I got all of the typos (speechos) fixed now. It's pretty rough doing final edits at 3-4AM some times!AMDfreak - Friday, February 20, 2009 - link
Nicely done review. However I find it disappointing that an exhaustive PSU review leaves out such a major player as PC Power & Cooling. Yes, OCZ was represented and I know they now own, PCP&C, but the ModStream line is not from PCP&C. If the Silencer 500W had been included in your review, I think your awards would be very different.
