PSU powerful enough?

I've got a Tagan 530W PSU.

My system consists of an E6300, Gigabyte DS3 Mobo, ATI 1900XT, 2x hard drives, 2x dvd drives, couple of usb devices (bluetooth etc...).

Anyway, when under load, usually playing BF2142, it starts beeping. It's a constant high pitch beep, definitely coming from the PSU (I've disconnected the case speaker).

I've got Speedfan and my 3.3v and 5v rails are fine, running at 3.26v and 4.95v under load. Speedfan doesn't seem to be able to monitor my 12v rail though, it just says 0v. I guess this is the rail that's failing? It's got two 12v rails, both about 20-22A.

The PSU isn't running too hot, or at least the air coming out the back isn't as hot as I've felt before. One thing worth noting, it's a 20pin mobo connector on the PSU, and it's hooked up to a 24pin slot on the mobo. According to the mobo manual this should be fine though. Could this be causing the problem?

Anyone got any ideas? Is the PSU underpowered, or just not working properly (530W should be enough shouldn't it)?

Just want to diagnose the problem before going and spending £100+ to replace a £75 PSU.
 
power-wise 530w should be ample and tagan is a decent brand, how old is the PSU? i think most tagans come with 3yr warranty so if the rail is going you should be able to RMA it :)
 
Yeah I thought as much. It's under a year old so think I may have to RMA it.

Would like to get a 12v reading just to be certain.

My Tagan Easycon 530W went under in less than 6 months of usage. If you need to spend that much to RMA it, you might as well as get a new one.
