Possible issue

[ZodiarK]

due to the lack of power sockets in my bedroom i currently possibly stupidly have a my pc,sub,monitor and test bench running off a 20m single extension cables connected to a 4 way 1m extension cable, i upgraded my pus to 1kw and im unsure if this is safe now.. as already today my pc turned itself off for no reason that i could figure.

any thoughts, i am thinking about rearranging the entire room so i put the pc right by the socket where currently my bed resides.

Im no electrician, but ive seen a fair bit of ringmaining done. An extension is essentially a spur and should handle the same as a standard socket on the ring will handle, the consumer unit will trip if theres a problem.

All i would suggest is you get a surge protector anyway, not for any danger presented by the cabling you have, just added protection. Throwing a fusebox switch back on or replacing a fuse is easy enough but buying a new rig 'cos of a surge - very painful !

EDIT: All a spark would do anyway in the first instance for extra sockets is add a spur as its the easiest way to extend, id guess few sparks would break into the ringmain unless specifically asked to do so, its a bigger hassle for teh same result.

13 amp fuse on main extension? 13ax230v=2990watts rounded off to 3000 watts

1kw psu 80% eff will pull 1200 (no way your maxing this out either) watts from wall leaving you with 1800 watts monitor probably uses 75 watts sub maybe 50 watts, so i'd say you've got plenty left.

thanks guys i was just a bit worried lol not really ideal though i think i will go ahead and move the pc and bed around.

not to mention that 1.5mm 3 core flex - which extensions are usually made from is rated for 16amps, so fuse would go first anyway before cabie gave way.

as someone has already said, break it all down.....

Ring-Main.... generally good for 32 (ish) amps total
Wall Socket.... 13amps per plug
4 Way adaptor.... whilst it has 4 sockets, it will not support 13amps across all 4, it will only do 13amps TOTAL

The weak point in all of this is that lead linking the 4 way socket and your wall socket, many i have seen lately are only using 0.75 or 1.0mm2 cable and to be fair, it would be better if they used a higher grade.

The other thing to consider, is that in your current arrangement, if one of the non-essential items has a problem, and blows the fuse, your pc loses power too, of course 99% of the time should one of those items trip to earth and blow the RCD protector then everything loses power anyway, unless you have the PC on a seperately protected supply such as a UPS for example (although, to be fair, even then you'll likely plug your monitor into the same UPS !)

Do you want some of mine? i have 8 spread around the room

[Gunslinger]

lol ... i don't want to count mine, i've got 2 UPS's in the room, and a number of sockets linked off those, i did actually count the number of sockets not long ago and scared myself stupid and promptly forgot the exact figure, i know i have 6 actual wall sockets available as part of the ring-main, and the 2 UPS's are connected to 2 of those, and in total off those i had something in the region of 20(ish) sockets available :o then there are adaptors connected to the non-UPS sockets as well one of which is an 8-way :surprised: :redface:
(biggest pain i find is all the tiny currennt draw items with power blocks, such as USB hubs, phone chargers, mouse charger etc etc, that due to their design all demand a plug socket)

This is the electrics in my room

All connect back to a single wall socket.

Been a setup like this for at least six years now with no issues at all :)

Daisy chaining extensions is kind of frowned upon, how you have that done is probably the best way to doo it if you must, however, if i needed that many sockets in the same area like that, i'd have been inclined to use regular wall sockets and create an internal ring that then connected back to the original original socket, or removed the original socket and replaced the internals with connector blocks and extended the existing ring-main out to the new sockets ;)

[ZodiarK]

their wasnt one extension lead from the wall socket a single 20m extension cable then onto the 4 way i moved the pc now straight into the socket

[ZodiarK]

further to this problem i have changed everything around my pc has it's own socket no extensions now straight into the main ring and yet i find it will just turn it self off randomly no bsods or anything.

i recently had a new psu silverstone strider and it's only starting doing this psu is running cool enough, i just think it is the psu, but no idea what it is about it.

you have 100% stability? anything popping up in event log for windows?

[Gunslinger]

with the recent power supply change, and the newness of this issue, plus the fact that it will always be in the back of your mind, i'd try and borrow another PSU or, purchase a cheap one that's just man enough for the job and test your pc with that and see what happens.

I'd imagine that if it's not windows related, then it's likely to be hapenning as something warms up to normal operating temperature... which could be the PSU, but it's hard to diagnose on the fly so to speak, so as always get as much hardware out of the system as is possible whilst still leaving it able to boot and run.

EDIT:
forgot to say, for gods sake, make sure you dont have some software that is turning it off after update or something daft like that.... if your worried about that, use something like "shutdownguard" to stop software initiated shutdowns
