One of the most over looked best PSU's for the $$$

Is that a type, or does it really say 0 PCI-E connectors in the specs? As well as no PFC. And the efficiency is only 70%?

Why not get an FSP...$115 buys many PSUs.

For that price I would go for:

While 432W on a single rail is nice, I suppose my three rails(18A) can deliver something like that over two of the three rails and the third throws the amps up to 40A max. or 480W max.. supposedly. And it only cost me $100 sooo ya, go Corsair.

Silverstone ST50EF-Plus
Just the best thing on earth

I thought Snapple was the best thing on earth.

Snapple is made from the best stuff on Earth (which is apparently Silverstone power supplies). Good thing I stopped drinking Snapple a couple years ago.

Corsair HX520
$109.99 after $10.00 Mail-In Rebate
or
Seasonic S12 550HT
$129.99

In my opinion, there are the 2 best power supplies for the price.

And I regret getting my OCZ now, after reading this.

I find that comment funny - you a bragging about it running quite badly out of spec.

A lot of you guys dont know wtf it is you are talking about. A powerful single 12v rail design is by far better than a dual rail psu.

I find that comment funny - you a bragging about it running quite badly out of spec.

Your a fukin idiot and I advise you to know your stuff before you run off at the mouth.

Any 12.05 is well within spec as a PSU is allowed a certain + to - percentage from the 12v rail.

I have owned many psu's in my life time and not one ran at exactly 12v you stupid noob.

I agree 12.05 is within spec, but if I had a PSU pushing out 12.5 all the time I would RMA the unit, not good for the long term health of componants.

Oh no, not Mrs"They have ways". Go shove your "much better 600w" where the sun don't shine.

You sir do not know what you are talking about. It is alot better to have a single rail power supply, compared to a multi-rail power supply. Plus, if you do a little research, you will find out that there are very few "TRUE" multi rail power supplies. Most of the power supplies that "CLAIM" to be multi-rail, have a single rail that are split up into multiple rails, which defeats the whole purpose of having multiple rails in the first place. The companies that do this know that Noobs like you will buy(pun intended) into the myth that the more rails, the better.

Please enlighten me BYTCH

My Corsair is not a split rail, it is three 18A rails. It delivers a max of only 40A on the 12v though. :-/

But that's still 4A more than you can at peak on that single rail enermax. And thus almost another 50W to whatever devices I'm using.

After going through a number of multi rail psu's and then finally discovering single 12v rail psu's a silverstone being my first there is no way in hell i would go back to a multi rail psu with a high power drawing system.

I agree. The main focus should be on the 12v rail. Too many noobs look at total wattage.

Well that will really all depend upon the type of systems being powered. However its a well know fact that high powered single 12v rail psu's are the preffered choice for systems with high power draw.

Just to give you an example-

My best friend and I have exactley the same setup but only one thing makes us different. Our psu's.

My PSU is a PCpowercooling 750watt psu with a single 60amp 12v rail.
My friends PSU is a 850watt multi rail silverstone PSU.

We both have SLI'd 8800GTX's and are running the same motherboard and CPU.

His 12v rail while under load drops to 11.70v while mine remains at 11.85v.



That may not be a big difference but it still implies that stout single 12v rail PSU's are superior for these kind of systems.

This ToughPower from ThermalTake is the same price, but in addition to the EnerMax PSU, it has dual 12-volt rails, 2xPCI-E connectors, 80% efficiency, and a 3 yr warranty...

Comparatively, I would choose this Thermaltake over that Enermax...

ThermalTake PSU's are about as sh1tty as it gets and I see your one of the noobs that thinks 2 rails is better than 1 solid rail since you compared it that way to that enermax I posted.

As I read through this, and also the somewhat biased reported from PC Power & Cooling ( its from them and not from an independent tester), the general take as I understand it is that a single rail is better then multiple rails. This is because with a single rail, no wattage is "trapped", but all wattage is free to power whatever needs the power. I am not sure that this represents any real advantage, as long as sufficient wattage is provided to all power draws.

If the Thermaltake is really using a split rail coming off a single rails, then it would have the same advantage as the PC Power & Cooling psu, from what I read here. No wattage is trapped, because it all originates from a single rail. I myself use a Thermaltake 700wt and take comfort that its in mpilchfamily's list of good psus. I don't think its "crap" at all, and it has provided good service.

I have to agree that silverstone makes some great psu's. i picked up the one below for like 135 and it is doing great in my system

12.5v isn't out of spec.

11.4v - 12.6v is all within ATX v2.2 voltage tolerances. Kiddies need to spend more time studying and less time flaming. Also, linking to authoritative documents is your friend. It gives you a chance to figure out if you're right or not while you look for a source For example, I actually thought that the tolerance was ±10%, but since I took the time to do a little research I managed to correct the mistake before I posted.

It's not what you know, it's what you know how to look up. Let us now meditate on this truth and end this silly thread.

I can think of one other advantage of my Thermaltake, the modular cables, which means that I only have the cables I need and therefore have no extra clutter in the case. As best I know, PC Power & Cooling does not offer modular cables. Ok, I know some people believe modular cables increase resistence, but the psu I have is rated over 80% efficiency, and that seems pretty good to me. Also, aircraft use modular cables in their electronics, so its its good enough to keep a 747 flying, I think its good enough for my computer. Other than that, fewer cables in the case means better airflow and cooling, which looks good to me no matter who makes the psu.

Ok, I accept that most people have had some personal experiences that shape what companies they like or dislike. I have those too. I recognize that my bad expeiences are not shared with everybody, so I usually stay silent on them unless there seems to be a general problem occuring with everyone.

I didn't say that 12.5v was out of spec, though I personally wouldn't want a psu that was running that high. My post concerning the 12.5v was directed more because of someone else going on a rant against a second person when the second person had quoted the first about the 12.5v.

Since that time, the posting turned more to a disussion over rail types and psus rather then the original posted question, which has gotten lost or mixed up as time went on.

Yeah and for good reason

No its not, read it more carefully. Its rated UP TO 85% Efficiency[b] That doesnt really tell us jack sh1t as to what the real world efficiency is of that PSU, I mean hell Im sure for the first 5-10minutes it probably is over 80% efficiency but I can also guarentee you that after a few hours of running your PC or some gaming that its well below 80%. Probably more like 70%.

Also Thermaltake is not disclosing the full MTFB like PCpowercooling and Silverstone do.

The full MTFB would include the tested temperature and if the PSU was tested at full load.

The only info your Thermaltake is listing for the MTFB is the ammount of time tested. They purposely left out the most important details such as [b]temperature tested and full load. Both of those factors play a big role in the true efficiency.

Unfortunatly thermaltake is not the only company that is guilty of purposely hiding this info as there are plenty PSU companies that do the same. Just stay with good brands such as Pcpowercooling and Silverstone and you should be ok.
