New PSU = case fans won't work?

This is very strange. I just got a new PSU, and now none of my case fans will turn on.

The funny thing is that I tried plugging them into 4 different power connectors - even one that was hooked to a hard drive, which I KNOW works - and not one of the three fans would turn on. (they are daisy-chained together, but I also tried with just one of them alone)

Any ideas? (the PSU is this noisy thing, which might make its way back to the store. The case fans are part of this)

did the fans work with a different psu? if so.. then take that thing back.. and get a known brand like corsair, antec, PC power and cooling, or seasonic..
 
Take it back for sure and buy something like the guy above mentioned ^^^^.
 
It's time for that PSU to make its way back to the store. Right now.
 
LOL...yeah, if case fans won't spin up then something is terribly and unusually wrong with your PSU...return ASAP and just get a better brand.

I never though PSU brand meant anything...I thought that as long as it had enough power and connectors to do what I needed then it wouldn't matter...wrong! People are right when they say a good PSU is a must!
 
Thanks for the tips. I just ordered a new one.
The original PSU I got was well-rated (and from tons of people), but I couldn't have predicted the bad rail/connectors/whatever, or the noise (most users said it was either "quiet" or "okay", but I assume their last PSU's weren't as quiet as the one that just died on me. It was a good little 430w PSU, but I had a dual-core CPU, 2 video cards, 2 DVD drives/burners, 3 hard drives, and 4 ram sticks all hammering on it (oh, then I recently added 5 case fans, most with lights... and that's when it finally buckled. Still, it survived that torture for almost 2 years, after about 4 years of faithful service under somewhat lighter loads).

Never underestimate what a well-made 430w PSU can do for you. :) I guess AndroidVageta's comment applies here:

This. Well-rated, more wattage (I might try Raid soon, and maybe SLI, if it supports triple-screen) and a huge rebate. And modular. And I hear good things about Sunbeam.
It doesn't make ice cream though; I want my money back.

I'll echo Zero. Any of the PSUs he linked are good stuff. Corsair, Antec, Seasonic, PC Power and Cooling, Enermax. these are the names I trust. I had a trusty little Enermax 430W that I bought in 2002 or so that is still in good shape.
 
Thanks for the tips (and suggested PSU's), but what exactly do you find wrong with the new one I chose? I'm pretty sure it just came out barely came out 2 months ago, and hasn't been reviewed anywhere "official" yet (no articles)... How do you know it's a piece of crap, especially if all of its ratings so far are only 5-stars? (I'm not saying they're going to remain 5-stars as more reviewers pop in, but still) 7 out of 10 of Sunbeam PSU's on the Egg are rated 4-5 stars. The other good brands Zero82z pointed out do have a slightly better count, but I don't think that warrants a so-far-well-rated Sunbeam as automatically being "crap".

Is there some review article that I didn't find on it?

because its a sunbeam.. thats why.. the price is usually the ultimate give away one if it should be bought or not.. if all the comparable psu's of the same wattage are selling for 30-50 dollars more then the one your buying.. then theres obviously a reason.. the PSU is the heart of the system.. with out it nothing else will run.. its the one thing in a system you should never try to penny pinch on..

also second most important thing is the efficiency of the PSU.. higher efficiency equals a cooler running PSU equals less wasted energy equals less chance of it dying..

also theres a reason i suggested those PSU brands.. they all have great warranties and a proven track record that goes back for years in the enthusiast market..
 
There is a chance that sunbeam will run fine and be a great PSU. However the chance is much greater with a reputable brand like what has been unanimously recommended. We aren't going to come to your house and take away your birthday if you keep the sunbeam, but you asked for our advice. Good efficiency a good PSU makes.
 
HOLY CRAP DUDE, vist or post in the power supply forum before you do that again.

At least just post - I have xx $ to spend what are my best power supply options ? (include a complete list of existing and planned upgrade equipment.

Post first, buy second.

Well hopefully it will be many years before you have to do it again,

This post provide as a public service message to all forum members considering purchases.

Sunbeam uses mediocre or bad companies to manufacture their PSUs, and they typically rate them for loads higher than what they are actually capable of sustaining, as well as use low-quality components that make the PSU both more prone to early failure and more likely to damage your components by providing dirty power. Another giveaway is that the PSU you chose isn't 80Plus certified, which means both that it probably isn't very efficient, and that it might not be able to supply its full power rating, since 80Plus testing involves fully loading the PSU to capacity. That PSU also does not supply any combined +12V rating, which is not a good sign.

All of the PSUs I suggested are of much better quality and are proven to perform well under full loading. That's why I recommended them to you. If you don't know anything about PSUs, you should post a thread in the PSU forum asking for recommendations, since if you just go ahead and choose something that looks pretty, you may end up with a really bad unit that puts the components in your system at risk.
