That one is an even bigger piece of junk than the first one you linked too. The problem with most cheap/bargain basement power supplies is that when they go (some don't, but an awful lot of them do) they have a very bad habit of taking other components with them (usually the motherboard, video card, memory, you name it) as they have little to no over-voltage protection in them.
Here is a good read on what to look for in a power supply and what a lot of the terminology means, Power Supply Information and Selection - Tech Support Forum
and to give an idea as to how well cheap power supplies don't work, The Bargain Basement Power Supply Roundup Review
That being said if you can stretch it a few more ££, then something like this, Antec 430W Basiq Power PSU - Dual 12V Rails PCI-E and.. | Ebuyer.com
P.S. Would help to know what the rest of the system is.
