Power supply lead

Shambolicuk · May 28, 2013

Hi guys, i have just bought a new power supply which turns out to be a o.e.m version which did not come with a mains power lead.

I have a spare lead from i dont know where that will fit it which is rated at 250v 5amp (im in the UK), could anyone tell me for sure if that ampage is suitable or should i get one with a higher ampage?

Many thanks.

Standard PSU wires are 18 gauge and are rated up to 300V. However the most volts a PSU pushes is 12V. However the 12V rail on your PSU pushes a max of 34 amps. However, due to the large amount of 18 gauge cables and the relatively short distance, the PSU can push 34 amps just fine.

Now what is your PSU missing, is it the 12V 4 or 8 pin CPU power cable, or is is something else you are trying to power?

Silverstone states a maximum draw of 4 Amps for the AC Input for the Strider Essential ST50F-ES when using a 230Vac wall outlet.

I don't live in a locale that uses 230Vac. If your AC power cords have a fuse built into the plug then I would recommend at least one with an 8 Amp fuse.

Thanks ko888 i have been trying it with the 5 amp fuse and everything seems to be ok. My maximum power drawer is around 250w so i should be fine i think..

Shambolicuk :

At your power draw level you shouldn't have a problem.

At the maximum, that SilverStone stated, the 8 Amp fuse rating is recommended to be able to properly handle the large inrush current that occurs when the power supply is turned on so that the fuse doesn't prematurely burn out during normal use.
