i got a rocketfish RF-900WPS from a friend. i installed it in my system to find my computer is not posting and the psu is making a squeeling sound. any ideas on this and how to fix. if you need anymore answers plaease ask i paid only 25 for this and an alienware case either way i made out with this deal but really needed this psu. I have checked all the voltages too they all seem in order and did have everything pluged in.
 
just some more info i forgot to add. i know it is the psu cause i took it out and shorted out the green and a black wire to jump start it and was still squeeling all my computrer com[ponennts are working and will start with the psu but just dont post at all
 
Ive had a quick look on google and it sounds like the PSU is OK but the problem is AlienWare is DELL and DELL like to only use their own products.

Other users have reported the PSU works fine, but when connected to the system board they too get the squeeling noise and the computer wont boot.

Basically meaning you cant use a standard ATX PSU with your AlienWare build, but you need a DELL-specific one.
 

You're really out there.
 
Dell and Alienware both use standard ATX power supplies, there are a few exceptions in the Dell line up due to system size, but they are still wired to ATX specs.
The OP doesn't state that he has an Alienware system, he does state that he has an Alienware case that he bought for $25 along with the pos psu.
 
The problem is OBVIOUSLY the power supply. Rocketfish is worthless as a brand. It is Best Buy's house brand. If it has the Rocketfish logo on it you can bet it is a rejected product from a name-brand manufacturer.

Rocketfish products are worthless.
 
Some PSUs are mislabled - To correct label replace word PSU with Door stop - NOT sure if that is the case with this one BUT a possibility.

All kidding aside. You need to (1) swap the PSU with a know good PSU. or (2) IF the PSU is squeeling, or causing the squeeling, do NOT use it connected to your computer, unless LOOKING for a good reason to upgrade. The PSU should be checked out using a PSU tester, even better using a voltmeter. With the Voltment you need to verify the DC voltage outputs. Also place the voltmeter to AC and make sure the 20 KHz is not riding the +12 V. The Voltmeter check is only under minium load so not totally conclusive.
