The links listed below is my full cataloge of PSU information. Just about anything you need to know can be found in the PSU 101-102 link. The PSU Reference Lists are just that. A listing of top qualtiy PSU with there key features and price listed. It also provides some reviews of many of the PSUs to help you better make an informed PSU choice. Hope this help everyone here.

I'm just wondering how the "Recommended High Quality Reference list...U.S." was compiled......

For instance, some very good power supplies have been excluded....to include the Ultra X2 and X3.

You do include some, listed as good, which are known to have substantial problems. Case in point.....the Mushkin 550W. You list it as a "high quality and recommended" power supply while the review you link to says of it:

"Efficiency could be better, there's no power factor correction, and the performance decreased significantly when temperatures were increased. The crossload shows that a computer with a minimal load on the 3.3V and/or 5V rails is going to wreak havoc on the 12V rails and the excessive ripple on the 12V line makes me contemplate potential long term effects on peripherals.

"Overall, the Mushkin HP-550 manages to score a "6.5" Simply put, I don't recommend this product.

"Outside of actually putting out 550W, efficiency could be better, there's no power factor correction, and the performance decreased significantly when temperatures were increased. Ripple was high and crossloading potential is evident.

"The power supply looks nice, the cables are nice and they're modular, but you can't bank everything on a power supply looking uber-smooth."


Then there are mistakes in where you are numbering and typing the +12V rail(s) the various power supplies have.

Case in point........the Antec TruePower Trio 650. You list it as having 3 +12V rails and them being current limited.

But, then how did Jonny Guru find this:

"Since we've effectively determined that all of these +12V leads terminate to essentially the same place, the next thing to do is to hit a single connector with a load greater than what it is rated for as per the label. To do this, I simply put a 50A load on the 8-pin EPS12V connector. If this connector were on a single +12V rail capable, via OCP limiter, of only 19A or even split up between two 19A rails, then the power supply should shut off. I did this and the PSU did not shut off. So the conclusion is that the Trio 650W does not have a 19A per rail limit, nor does it have three separate rails." (From Jonny Guru's test of that power supply. And this is not the only one with nothing more than virtual +12V rails.....LOTS of "multi-railed power supplies these days are nothing more than single rail power supplies split "virtually" into multiple rails with NO OCP....or overcurrent protection.)


And this does not address the numerous other mistakes throughout your list. On the whole, you've a mishmash of incorrect information that is suspect at the least......it almost seems you just copied from whatever website you liked and never bothered to even cross check the "facts" that were presented.

Nice try, but I'd suggest you weed out the chaff, include some of the other better ones out there, and quit calling yourself a "Power Supply Guru" until you actually know what you're talking about.

First of all i do not and have never claimed to be a PSU Guru. The Admin over at Xtreme CPU where nice enough to award me that title. I'll be the first to tell you i don't know everything and still have quite a lot to learn. I beleive none of use will ever stop learning about PCs. I just thought i had some helpful information that i could shair.

Yes there are several high end PSUs not mentioned in the list for several reasons. Most important of which is the lack of information to accuratly determin the total amperage availible to the combined +12v rails. So PSUs like some Ultra models and Xclio models are not in the list. Also the selection of the list is limited by the selection offered at the given etailer. Muskin PSUs sit on a fine line of good and bad. As do the 580W and under Hiper PSUs, OCZ, and Zalman PSUs. So you are right i should call the list a list of High qualtiy PSUs since not all of the PSUs will fall under this title.

As for the Antec Truepower Trio and it being listed as 3 CL rails that is what is listed on the manufactures spec sheet for the unit. So that is what is put in the list. I try to keep the information to the listed specs of the units. Its up to the indivigual to check the reviews and make the final judgement for themselfs.

Now nothing in these list is final. I'm always looking for suggestions and help in updating and maintaining the lists. I currently use an MS Excel macro that pulles price updates from the web sites for me. As mentioned in the OP i try to update the list about once a month. Every couple of months i may perform an overhaul to try and find new and/or better reviews of each unit. I rely on a couple of pre existing lists to help me determin which PSUs belong to this list.

Mainly i refure to the list over at Xtremesystems. As you have noticed i do pull some brands and models from tier 4. These units tend to be good options for basic systems on a budget. Now Jonny's list sticks mainly to the high end so it is limited. I like to keep a range of PSU for every system. Besides i don't care to visit hiw Forum very often. There tends to be an air of i am better then you so why are you even talking to me. These types of aditudes are the ones i like to avoid. Part of the reason i'm here now and not at TG.

Once again if there are any additions, corrections, deletions, or updates that need to be made let me know. I can always use a helping hand on the lists. I have recently updated the list to exclude some of the units and update the information. I have reduced the listing of the # of +12v rails to what the manufacture shows and have made not that the actual type of rails will very from unit to unit. As you mentioned most units have Virtual rail not Current limited rails. I was mistaken to refure to them like that.

Thank you for all your recomendations. I look forward to any other corrections you may find. If you care to take the time to look over the list again.
