So I'm sitting here doing a bit of window shopping as is my normal routine when sick. First I started out by looking at a complete overhaul, i5 to i7 and a a new GPU etc. Thankfully I realised that is a stupid idea and I could spend some money else where, eg SSD or UPS which are two things I really want (apart from an iPad). The problem with the SSD is the small capacity and the fact it gives me a headache thinking about how to install all the programs and games etc on two separate hdd, which is the suck.
So now I am onto UPS, which is making more sense as I read into it. Basically everyone needs one.
Calculate how much power you need
External HDD 20
+20% = 1068
These figures are quite rough as I guessed. So for my computer I am going to need something quite powerful. For the HTPC I have worked out it is drawing about 230w, but I'm pretty sure I put a 650w PSU in it. In any case I just need it to last maybe 5 mins while I switch the power back on in the box.
