My is squealing a very high pitched noise. Started a few days ago and hasn't stopped. It's a Antec Quattro 850w, and is only about 4 months old. What's wrong?

And one possible solution..... I have two slots on the back of the psu. Both 12volts and 25 amps. Each of those two, I guess there called rails, are connected straight from the psu into the two power connectors for my Graphics card (ATI 5870). Thats ok right? Should be

yes those connectors are fine, ive found good reviews of this ps, so i cant tell u whats causing the squealing, with certain power supplys the decibel levels are higher than others, but for this specific model i havent herd that its a loud model, shur someone else could add to this

Ok you kinda lost me there lol

There's a pic of my psu. The main cable coming straight out is connected to only the Mobo and cpu

Then the 3 other black spots are connected to the hdd, drisk drive, and fans.

Then the 1st red one goes to the Graphics card only

And the 2nd red on goes to the Graphics card only

Should be good right?

Ya, ya ok. Out of that all those strands on the "non-removable" strands, those are only being used right now for the cpu and mobo. So your saying use 2 of those seperate non removable strands and connect them to my 5870?

it pretty simple , those 2 6pin connectors fit well in ur gpu, they dont really fit anywhere else, not that ive used them anywhere else if im not mistaken, so its not rocket science , thats my 2 cent

I think the problem is that I'm not correctly using those 4 rails. 4 rails seems like a stupid idea right moe lol. I'm thinking a might just get a one rail corsair. F*** antec lol.

well the thing is , each rail delivers a certain wattage, so the 4 rails combined in ur 850 watter should deliver close to 850, if that, most powersupply dont advertise the real maximum wattage,

honestly u have more than enought power to power ur gpu, unless ur powersupply is faulty, u can always rma it, or buy a new one, but if it works why change it :p

yes, usually u must pay for more rails, which is not needed, some very good single rail powersupplies such as the hx650 corsair, does very good wattage and effiency , and is a single railed model :D

Alright I've found the problem. Had nothing to do with how it was connected as I thought. My psu just went bad because antec uses cheap capacitors. Read reviews and all the bad reviews say the same thing, "psu started squelling". Def goin to stay away from Anted psu's from now on. Corsair psu is on the way. Thanks for answering my questions guys!
