Superflower 1300 question

rossiboy001 · 15 Apr 2015 at 19:24

I bought this PSU recently for a crossfire upgrade. However it came with a foreign plug which says 16 amps 250v on the plug, i assume its got a 16amp fuse? Overclockers have since sent me an OK Value kettle lead for a UK plug, However its got a 5amp fuse, which can be replaced/opened ect.
I haven't installed it yet, but i thought this morning i would just try to switch it on see if the fan and the lights work, now i have a kettle lead.... Nothing, Im assuming i need to install a 16 amp fuse, but thinking i can just buy one, they are apparently not available from shops and dont fit UK plugs.
How have others got this PSU going. The only thing i can think of i have not tried yet is plugging in an old PC to it to see if it only works if it senses a connection and thats all it is. But just plugging it in with the supplied kettle lead, does not make the fan or lights switch on, by itself which i just wanted to test to see if it functions?

So i dont need a 16 amp fuse? its a 1300 watt gold?

After reading the samll print in the manual, apparently the fan does not spin until it reaches a certain temperature to save power, So its not a visual indicator that the unit functions. which is what i assumed wrongly. However the connections do not illuminate on their own, i guess i will have to test them in using an old pc i have knocking around i can quickly connect to. My question is then if a 5 watt fuse within the plug will only allow the PSU to work to 1200Watts, should i change it to a 13amp fuse to fully utilize it, interestingly enough it came with a euro plug fitted with a 16 amp fuse which does not fit UK plugs.

you use voltsxamps to get watts and the normal is to use 230 for the uk due to voltage fluctuation so 230*5=1150watts

realistically you shouldn't be pushing near to 1150 with a 1300 watt psu so 5amp fuse will be fine If you use a 13amp fuse it's very likely the fuse won't pop if there is a problem which increases chance of fire or destruction of your pc.

3 amp = 690 watts
5 amp = 1150 watts
13 amp = 2990 watts

(i've always used 230 volts in the formula as advised by a eletrician as it gives you a little bit of head room so to speak dues to poor quality voltage regulation (varies from city to city and house to house)

Thanks So realistically I should consider this unit to be a 1150 watt PSU unless I upto a 13amp. I guess I can live with that for xfire. So reading all the posts in the graphics card section Im assuming then all those people going tri fire pushing this size unit to capacity and a little beyond are taking risks with their hardware as they wont have an alternative than to use a 12 amp fuse to go beyond 1150 watts.
