Raidmax power supplies?

Don't be so obvious with the sarcasm 😉

Anyway...
Raidmax Power supplies are normally regarded as... junk?

Check out the output:

Output +3.3V@28A, +5V@34A, +12V@14A, -5V@0.5A, -12V@0.8A, +5VSB@2.0A

Now--you'll never have anywhere NEAR that much amperage necessary on the 3.3v rail.
Most likely the 5v rail, too, unless you use an absurd number of accessories.

On the 12V rail though... that is another story.
Most CPUs will draw in an average of 10 amps [Slightly lower if its an AMD proc, much higher if it's an intel...]
Most GPUs will draw in another 10.

That thing would crash and burn very soon, possibly taking your computer with it, and you'd have extremely wacky voltage rails in the mean time. [Starting, stopping, freezing, etc.]
 
If you do buy that one please set a timer by your pc and let us know how long it takes before it goes up in a shower of sparks. Pics would be nice especially if a fire is involved. Never ever skimp on your ps as it's the one component that supplies your entire pc with power. I personally run enermax in all of my machines but fortron and seasonic are good units.
 
Your linked Raidmax is a POS PSU...OK.
I've reached a point where Newegg is a pita, the pics there are pretty but the customer reviews are generally by uninformed fanboys trying to justify their purchase choice.

Buy this http://www.ewiz.com/detail.php?name=PS-FS400GN It's a more current model Fortron, more efficiant and cheaper than the Egg Fortron linked above this post.
I can hear it now*whining* "I can only shop Newegg", I hope that's not the case.

Consider this Enhance PSU. Enhance is considered by those in the know to be a step or two better than Fortron. Not that Fortron is not good but Enhance is better yet.
The fan on this unit MIGHT be a touch louder than the Fortron. Given the choice, I'd opt for the Enhance unit linked below.

Best I can do for you mork but now some silence freak will come crying into the thread posting SPCR uber-quiet crap telling you either linked PSUs will cause your ears to bleed and early hearing loss. Then telling you to get a passivly cooled PSU or a Seasonic. Kripes!! 😉

Two points here...

1) A poorly phrased question when we all know you can't go by brand name alone. You have to evaluate specific and complete specs for the model in question.

2) speaking of specs, that one ain't makin' it due to not enough +12 volt power...

Output +3.3V@28A, +5V@34A, +12V@14A, -5V@0.5A, -12V@0.8A, +5VSB@2.0A
 
The PSUs they usually supply with their cases are the L&C/Deer bottom-feeders. I can't read the UL file number on that one so I can't tell who actually makes it - but it doesn't look like an L&C. In any case, it's and old design that claims to put out 14 Amps on the +12 (single) rail. If you plan to drive a modern system with it, then it's probably a no-go. Modern systems require more support from the +12V rail(s) than the 5.5/3 rails combined. Rule of thumb is twice the total Watts from the +12 rail than from the 5/3.3 rails combined.
. Now if you're driving an older system that has no P4 connector on the mobo and has no PCI Express slots or plans for using SLI, then the distribution of power across the rails of the Raidmax would be appropriate for that. But the 300 watt fortron that I'm selling in the For Sale/Trade section would likely do you better for a lot less money and I also have a 400 Watt unit that would KILL that Raidmax for still a bit less money. Just click the link at the bottom of this post to check them out and make me an offer. 😉

Now what did you have to go and do that for? 😎

The OP didn't make any mention of noise so that really opens up the your options. My recommendations would be Forton-Source, Seasonic, and Enhance; these are all top tier manufacturers who have a reputation of quality and standby their products. Buying from companies that rebadge other units is too much of a guessing game and since they don't actually produce anything, who is to say they won't disappear in 3-6 months time?

I've spent about a year now really looking at the PSU market and have come to conclusion that I'll only buy from actual manufactures of the PSU themselves; Forton-Source, Seasonic, Enhance. The only exemptions from this would be SilverStone (Enhance) and Zalman (Forton-Source).
 
Noooo! Don't get any of those ones! They're so damned loud your ears will bleed! I recomend the near silent PCP&C 1KW. It should be able to handle your system and it's so quiet it's amazing!

Alternativly, GY's suggestions are good 😉

Would be nice if you had an actual clue via ownership of a PC Power & Cooling product.
Or for that matter poll those of us who own one.....
Its amazing what being able to own one can do to your out look....

Also again your are sounding like a vacuum cleaner dude.....in fact you are drowning out the loudness of the 1K PSU.....

Again you quote SPCR.....yet it would seem those of us who own a PC Power & Cooling PSU iether don`t agree with you or the quality and workmanship and piece of mind far out weighs a a supposed minor noise issue.

The fact that PC Power & Cooling has added a heat sensor that powers down there fan to make them quieter actually doesn`t matter to you becuase you are a proponent of cheaper is better,,,or well hell a 300watt PSU will power that rigg...

So show me an recent current review of a PC Power & Cooling product that says they are loud....

Conclusion-- TurboCool 850 SSI.



PC Power and Cooling hasn't simply offered us another more powerful PSU this is in fact a departure from previous designs. Over the years PSU design has become homogenized with just about every design sharing of capacitors, transformers, and other stages. The end result is a compromise dictated purely by a profit driven market which has minimized the role of the PSU.

In their attempts to cut costs, system builders used PSUs which just barely got the job done. It was in fact PC Power and Cooling whom departed from the prototypical design to give us the archetypal design back in 1986 and today on their unofficial 20th anniversary they've redefined what a PSU can be. XtremeOverclocking has published an excellent guide to PSU Truths and Misconceptions. An underlying theme repeated in the article is the influences on design-integrity cost have had. In the guide they allude to the ideal PSU being a proprietary design were it not for cost considerations.

Today PCP&C has given us such an animal and it's currently the most powerful unit on the market. At $469 it is perhaps the most costly, however; in this case you truly do get what you pay for. A 5-year warranty, unrelenting power, silent operation and a PSU able to power multiple SATA, SLI graphics cards (each with a dedicated line), and the load demands of any desk-top system thrown at it.

Be sure to visit their website which has been completely redesigned. Many will be excited to find their lists of re-furbished PSUs for sale with prices ranging from $24 to $239 and many units are the (originally) higher priced custom units built for those with unlimited fund.

The false impression their PSUs were prohibitively costly evaporates with the launch of their new site. Stay tuned for our second part where we test the TurboCool 850 SSI on our DFI motherboard with nVidia graphic cards running in SLI mode. I would like to thank the folks at PC Power and Cooling for the opportunity to test their TurboCool 850 SSI.




 
Nice thread guys. I just came here surfing for RaidMax info cuz mine just bit the dust. HARD. No sparks or flames (thank goodness) but a couple of days of heavy ozone smell followed by a total funkification of my office on the day of defeat.

I picked this thing up at MicroCenter for around $20 on "special". It has 25A on the 12V but it doesn't really matter now that it's toast.

Anyways thanks for the validation; I'll probably pick up a fortron or something now.
 
I found out that the Raidmax PSU is made in the PRC by Sun Pro Electronics Co, Ltd. Totally unknown. But the price is today $22. shipped AR.. Whooee, getting better by the second!

Hmmm. Sadly, it's the power supplies that are hurting my addition to the crack rack. I wonder if these POS PSUs would work for it or not... Hmmm.
