So I got the Raidmax RX-700AC 700W 80 Bronze and after getting it I began reading about it. At Newegg it got 4 out of 5 eggs, but so many people are complaining about the brand Raidmax?

So I just wanted to know, if it was stupid of me to buy it?

I can't find a review for that unit, in particular, but Raidmax units are usually bottom of the barrel, lowest quality possible stuff.

Take a look at Tier 5 here: http://www.eggxpert.com/forums/thread/323050.aspx


That list is based upon opinions, not real facts.

Because of their past history of crappy power supplies which usually blew up when any significant chunk of power was pulled. Not to mention they've false advertised quite a few times, overrated units, and just generally put out cheap and dangerous chunks of scrap they call power supplies.

The newer ones they have nowadays are at least serviceable. The new ones aren't highly efficient nor well designed but they at least do their job and that can't be said for their old psu's.

Can they break the stigma of cheap shite that explodes = raidmax that they've made over the years? Possibly. Until they absolutely phase out every old unit, consistently put out new units that are rated appropriately and turn a page then theyll be forever known as the shitty PSU brand that blows up 99% of the time.

In other words. They'll most likely have to change their company name to get rid of the hate that comes with their current name due to past experiences / word of mouth / opinions.

How do you figure that? It just says that someone may have their own opinions and that you should check the reviews.

That list is based on a amalgamation of reviews from various sites. There obviously won't be a review for every single PSU in existence, but it gives you a very good idea of what's a good unit/company and what isn't

Besides, Newegg Feedback is ridiculous (and it definitely is based purely on opinion). 90% of the people that post feedback there literally have no idea what they're talking about. If it isn't DOA, they give it good feedback.

Edit: The newer units are still made by Andyson, so that doesn't inspire much faith in the quality.

Because of their fairly limited knowledge about hardware, there will be less opinion based reviews. They only conclude on real world usage, not by the numbers on the specification list.

In 129 reviews there had been about 87 - 5 out of 5 - Which is what I would say, reliable enough for me to believe in. As some of the other guys mention, they have a bad reputation. So as I mentioned before, they have fairly limited knowledge about hardware, then they won't look back and let their reviews be "colored" of bad times in the bast for Raidmax.

So I can't use a list, where PSUs that might have been used 10 years ago paint a picture of how things are now.

If you look, that list is up to date, as of 11/10/2012, but whatever makes you feel better. I know the truth.

The newer units may not literally explode, but as I said, they're still manufactured by Andyson (a piss poor OEM), so not much has changed, even if you want to believe that the reviews are "10 years old" (they're not).

The only good thing is that it's 700W, so you won't really be stressing it much (assuming that you're not using multiple GPU's). Thank your lucky stars for that.

Edit: And I don't care what the Newegg feedback says. You should never base your purchasing decisions on Newegg feedback (ever).

Newegg customer reviews dont mean anything, the standard person doesn't have the tools, knowledge or ability to properly test whether its any good or doing as its supposed to.
All they can do is plug it in and see that it didnt blow up.
I have a generic PSU that will run a system, that doesnt mean its any good. Chances are the thing is well outside 80+ standard and couldn't output half its advertised wattage if you did try.

For instance, DIABLOTEK has a similar reputation to RAIDMAX. This 1050W unit failed to output more than 600W, and when it did so was well outside ATX specifications.
The unit performed so poorly that the reviewer doesn't even try to be serious about reviewing it.

EDIT: Also just looking at the PSU I can tell its low quality.
Doesnt have Active PFC (which is a standard feature among PSU's) and has two 12v rails (which they claim "provides added system stability", utter rubbish).
Heres the link to the unit.

Well considering RealHardTech only has 5 reviews of their entire lineup, 4 of which sites I've never even heard of. The reviews listed are only on their gold lineup. Since you seem to be so convinced that newegg opinions matter what does that say about raidmax? Most review sites have just given up on even trying to review their products. Its not worth the time or cost to invest in a bottom of the barrel companies power supplies.

99% of raidmax powersupplies are disgusting pieces of garbage that you should never even look sideways at. Perhaps they would make a good gag gift for the more technically inclined crowd? And yes this last paragraph is my personal opinion, even though its a widely accepted one.

http://www.realhardtechx.com/index_archivos/Page6337.ht...

(And no I am NOT going to try to find reviews of every single power supply in their lineup. Hence why I used RHT)

Oh and whats up with this sentence, bolded for emphasis:
HIGH THERMAL PERFORMANCE, QUIET 120MM FAN
The internal 135mm blue LED fan maximizes the airflow and guarantees silent operation.

It also states its ready for multi gpus despite only having 2x 6+2pin PCIe connectors...

Cant really use that against me when your lying/wrong about the model you have.


Wow, easy there!

I'm not saying you're lying. I know what is inside my computer, I can even take a picture of it myself. I can just tell you what is inside of my pc, and what isn't. Not the quality of it.
I feel that I now am more aware about the PSU world after all of you have been helping me. I've never been paying so much attention to them, more to the MOBO, GPU and CPU.

In the future I will use all your adviceses, I won't be buying a Raidmax again.

Luckily my whole pc got a 2 year warranty, so if the PSU damages any of the components I get a new pc. :)

I can tell you it has. I got a GTX 660 in my pc, and it requires a 6-pin connecter. I have another 6-pin connecter, which is unused. So it does have 2 6-pin connecters.

You missed the point. A true 700w PSU (Not that bargain bin one you have) is enough to easily power dual GTX 680s or dual 7970s. It only having 2 6+2pin is an obvious testament to its quality. Thats what we were trying to get at.

Wasn't doubting that it had two connectors, just that mid-high end cards require two connectors each. So if you wanted to Crossfire/SLI anything more powerful than a 7770 or 660, you wouldn't have enough connectors (which should be present on a 700W unit).

Let me get this straight, I'm sorry if I seems stupid.

The watt of the PSU is like the "play-room". The 80+ means that it is power efficient. And at last - the bronze certified means that it has good/decent stability.

The biggest, best and most succesful producent of gaming pcs here in Denmark mostly, if not only, uses these Raidmax PSUs. They promise 2 years warranty, so I don't see it getting set on fire or something sooner.
If they have such succes, they get voted to best gaming pc of the year and so on, then how can the PSU they are using be so bad?

The MOBO I choose only supports 1 GPU, so I won't be needing more pin connecters.

I choose so high as 700 watt to have the ability to upgrade in the future.

Watts is a unit of power that means Energy/Time (Joules per second).It can also be found by Voltage (Energy per Coloumb) x Current (Coloumbs per second). So a 500W unit can output 500 joules of energy per second (in DC current).

The 80+ certification states that its voltages wont stray more than 5% of what it should and that it is at least 80% efficient in converting AC (wall power) to DC current (which the machine can use). The different ratings (Bronze, Gold, etc) indicate higher levels of efficiency in this conversion.
Though I am not sure if whether a supply is independently tested or if its up to the manufacturer to prove its 80+ certified. As some supply's have been released that absolutely miss the certification that still carry the sticker.

You could have a 550W unit and still be able to run a strong graphics card and CPU with some headroom.
Also just because it says 700W doesn't mean it can put out 700W. That 1050W I posted above literally blew up trying to output more than 600W. Which is a fairly good sign its an overrated 500/550W unit.

Hmmm, referring to the wattage on the power supply as "play room" isn't technically wrong. (In a world where power supplies were Based upon real world usages of said power instead of the collective wattages that the system has available you would be absolutely right). However for most inexpensive power supplies (not even cheap ones, some times decent companies do this also) a PSU is rated based on the collective amps across all of the various voltage rails.

To put it simply take a look at this unit. (http://www.newegg.com/Product/Product.aspx?Item=N82E168...)
In the spec sheet you would notice that the amps on the 3.3v rail is 38A, to get the relative wattage its just simple multiplication, 3.3 x 38 = 125watts (I'll now do the same with all of the rails)
5v x 40a = 200watts

Now normally the power supply will tell us how many watts are available on each of the 12v rails however this one does not. We can't simply add them together as its a dual 12v rail PSU.

However you might think, well this PSU is pretty decent it can supply 325watts + whatever the 12v rail is.

But what they don't tell you is the 3.3v/5v line is used only for low power devices like hard drives, dvd drives, fans, etc.

So why would they put nearly half of the wattage on those typically unused rails? Simple, because they can and people think, hey, cool a 680w PSU, imma buy it. And thats that.

The 80+ efficiency isn't all that useful either, its exactly what it says it takes power from the wall and converts it to power your PC can use. (AC to DC) From my understanding all thats required to gain that certification is to simply make your power supply more efficient it doesn't need to be stable it doesn't need to be made out of quality components. They also only do the tests at 20%, 50% and 100% load. They do these tests in an unrealistic environment from what I have read, around 25c. Dunno about you but my house is usually around 35c+ and the inside of my computer will most definitely be a lot hotter than that.

So lets take a 1000w PSU for easy math, all it has to do to pass is simply to not waste more than 20% power. so 1000W @ 80% efficiency has to not waste more than 200w. (assuming 100% load)

There is more to PSUs than wattage, but I don't feel like going into this subject any deeper for right now.

Sorry if I made and really stupid mistakes in writing this I'm half dead its 3:30 AM here.

Edit: Ah man beat me to it by a good margin. I should refresh before posting :)

That is actually also something I've always been wondering about!!

The "play-room" of 700 watt seems like way too much, because my system uses about 55 watt on idle and 155 watt during 3dmark.

So it's because of the watt can't be provided, even though it was meant to.

Quality PSUs provide more power, even though they might have less watt. Did I get it?? :o

Power is Wattage, quite literally.

Can you rephrase that? I dont understand the question.

EDIT:
Quality PSU's can provide the wattage they advertise over the one rail that really matters (the 12v).

Every PSU will have a 12v rail, just like they will also have a 5v and a 3.3v rail.
Suppose a better way of saying what I said above is.

A decent PSU will stay within 80+ standards under expected loads, can sufficiently supply the power advertised and wont blow up while doing so.

A quality PSU will strictly hold to 80+ standard (or better, my Silverstone doesn't stray more than 3% according to reviews) under expected and reasonably higher loads. Can supply the amount of power advertised and possibly more and wont malfunction while doing so. Also having a good feature set like modular cables, automatic fans and higher efficiency.
