Thanks people. Shall aim for the best I can afford with a minimum of tier 2.
And £42 from a store thats closing down, therefor no warranty, isnt cheaping out but is considered a bargain? Okaaay..
If you're slowly putting it together you'd be gutted if the system blew because of that old power supply, always try to get the best power supply you can it's simply not worth 'cheaping' out on
I don't see why lower tier psu's shouldn't work just as well as higher ones. You'll just be buying something that doesn't have as good a regulation, higher ripple noise, lower voltage stability, cheaper electronic parts (eg, capacitors) & probably will get warmer hence the need for a fan, a noisier one of course. Most of this won't matter tho' as it'll still or should perform within the specification guidelines but because it's built to a certain budget it may not last as long, however that's not to say it won't give many years of faultless use.
Careful there are some EVGA products in Tier 5 down to 7. Some people will have a nervous breakdown. Tier 1 for me and a 2 I think.
