I'm after a new PSU as the fan on my old one stalls sometimes, or makes loud vibrating sounds. It's only 300W, and that probably wont be enough when I upgrade big time in December. I've been looking at these two:

What do you think to these? Another question, my current PSU uses a 2x2 power connector as well as the standard 2x10 one. The mobo book says it's to power the CPU. For a start, will the new PSU have one of these connector's and if not, will the PC just not work?

Cheap PSUs. You will get what you pay for.
Nowhere in the product specifications do they say how many amps you get on the 12V rail. Most recommendations I've seen on this forum say go for a quality PSU with at least 18amps on 12V rail. If you click on the comparison link on the page you refer to then you will see what you will pay for a quality PSU such as antec.
If you buy one of the cheapies then you risk it failing in short order and when it does it will probably take out your mobo/cpu and other stuff as well. If you are looking at a serious upgrade in a few months then don't risk a low quality PSU.

The reviews on the cheap one say it's by Magna, anyone had any experience with these?

I used to have a cheap 550w psu which was great for around 9 months or so,but when it went down it went down.I had to relace my motherboard as it was a strange fault.My pc would boot and work as normal,but after a while everything would go sloooow.Was trying every work around ...bios updates...virus scans...etc. then when I actually flashed my bios the psu gave up half way through.This was the answer all along (faulty psu).
I learned my lesson the hard way ...why should you! Don't scrimp give you system a solid base to work from.Get a decent psu with a good rating on the +12v rail its worth it trust me .

YEa, Antec is a good brand, but ALWAYS check the specs. Richard59 gave you some good advice...check for the amperage on the +12v rail...18A minimum seems to be the recommendation.

The reason is that many components pull power from the +12v rail. The CPU alone can account for as much as 10A...each optical drive needs about 1A...HDDs need about 2A each...cooling fans use about 0.25A each. And if you have a high power video card that requires an additional 12v plug, that's even more demand on the +12v rail.

If you plan on doing any upgrading in the future, buy a big enough PSU to handle the load...a 330 watt unit maybe OK for the time being, but you may find you'll need something more powerful down the road. I recommend a 450 watt unit with dual cooling fans & no less that 18A on the +12v
