Power supply

My current power unit box thing is on its way out. The fan makes a terrible noise, it is overheating and burning a bit.

The current power unit is and Power Man FSP250-61GN(AMD)

It has:
-AC input: 115/230V~, 8/4A, 60/50Hz
-DC output: 250W

Most of this makes no sense to me, I just copied it off the bottom of the power unit.

Would this work as a replacement:

Thanks.

Quick question -- do you believe your PS is just showing its age, or is it overloaded for your system? 'Cause if it's old, the one you linked to would be a fine replacement. But if you've been sticking in more drives, a bigger video card, etc., and now the PS is getting cranky, you might want to think about going with a beefier, better-cooled PS.

Your current PS is a 250-watt model, and the one you linked to is a 300-watt. If you're thinking about pimping your rig, neither may be enough.

I think the fancy machines with the hot new video cards are supposed to have PS of 400-watts or more. One really hot rig had a 600-watt PS I think.

If you really want to change your PSU (I think you should), don't get cheated by the loads of Watt advertised with them. These gadgets have a specification called "true power" with their advertisments -that is the same cheat made with speakers' PMPO Watts and RMS Watts (the actual output is RMS Watts for them). A quality PSU generally "speaks out loud" of his true power

So look for a specification calling " X Watts of True Power " in a PSU before your purchase. And don't pay anything for a PSU with a true power no less than 400 Watts so that it will suit your needs in the future as well.

No, I don't want to upgrade my computer. I want to buy a new one in about ~6 months.

I went to PC world and showed a person in the shop the current PSU and they suggested the one on the link. I did not tell them I had been on their website.

So I bought the thing and installed and it works fine.

So this thread was a bit pointless.

The AC numbers are for the power that comes out of the wall in North america (120 Volts at 8 Amps and 60 Hertz) and the UK (230 Volts at 4 Amps and 50 Hertz). Your power supply retifies that into a DC value or either 12 volts or 5 volts with a maximum power out put of 250 Watts (power is the square of voltage times current).
