How to know how many watts has my power supply?

[Talayero]

Hello,

my PC's power supply hasn't any label or inscription with its characteristics.
Is there any way to find them out? I tried Everest Home Edition but I didn't get the information about the watts.

The thing is I have now 5 hard drives and 3 optical devices in my PC and I'm afraid that the power that was installed years before isn't good enough.

Thanks in advance.

I'd appreciate also any advice about good power supplies or about the power I would need for that hardware, 5 hard drives, 3 optical devices, 3 pci slots... More than 300 watts, I guess.

Hi

Only the sticker can tells you.

I managed to find a sticker.

It sais:

MX Model LC-A300 ATX.

Output 300 W

+3.3 V 20A
+5 V 30A
+12V 10A
+5VSB 2A
-5V 0.5A
-12V 0.8A

So, I suppose I need a better one.

Yeah I'd say 5 hard drives on a 300W PSU is pushing it, I had sporadic problems on my old 350W one with 4 hard drives and a Radeon 9700. I have an Antec 550W one that's really quiet now and I haven't had one problem since with the system (that wasn't my fault for screwing around too much).
