    A bit OTT in terms of wattage for the system you have,but seems a decent PSU:

    Although a bit higher wattage than you need for your spec, still a good PSU and allows you upgrade and still have a decent PSU to handle the upgrade. I have the G2 650W and love it. Plenty of warranty and modular too. I have had a few Corsair PSUs and they have failed on me but the EVGAs still going strong.

    Ebuyer £65.99 inc VAT & shipping.
    CCL £66.26 inc VAT & shipping.
    AWD IT £68.99 inc VAT & shipping.

    After reading the JonnyGuru review of the EVGA BQ 750W I think you'll be able to snag something better.

    This close to black Friday I'd probably be tempted to wait to see what else comes up.

    You may also wanna check out Amazon Warehouse deals, currently 20% advertised price at checkout. I've had some decent items out of there in the past. In the past AWD have been helpful with issues after even the 30 days satisfaction guarantee, occasionally if it's a fairly new item/return it may even have the manufacturer warranty left on it. It's FOC returns within the 30 days as well, I've also had discounts in the past if the item is not as described in listing/missing accessories, etc.

    Seasonic S12-II 620W £63.23 = £50.58
    BeQuiet 700W Pure Power 9 £87.37 = £69.90
    Corsair RM750X £102.25 = £81.80
    EVGA Supernova G2 750W £108.43 = £86.74

    If modular isn't a must then the S12 II is quite a good buy IMO.

    Scan EVGA BQ 650W £39.98 inc VAT from Black Friday to Cyber Monday, as you have 20 Hexus posts you can have FOC delivery. There are other PSU on offer as well.

    Re: Wanting a new PSU

    Thank you all.

    Even though scan offered the EVGA at £10 less - ie no postage. I finally went with gupsterg advice and bought the Seasonic. Hopefully I've done the right thing. I notice that the seasonic is a tier 2 psu and the EVGA is between tier 3 and 4.

    I'm sure that either would have met my needs but I decided that quality is more important than features and so went Seasonic at £50.58

    Hopefully it will work when it arrives!

    Most frustrating thing is that I forgot to use my gift card to buy it! I had a £10 voucher for amazon and paid with a credit card. That will teach me not to rush when placing an order.

    Thank you for getting back. I hadn't realised that using an overrated PSU would be less efficient. I had read that the rating wasn't the power that was consumed, it was the amount available. Yesterday, for the first time however, I started reading the efficiency stuff, which seems to suggest that you want to be using the PSU at about 50% load in order to maximise the efficiency. So if the computer usually uses 400W you would be good to have an 800W PSU but it you typically use 250W you would want a 500W PSU - assuming I've got this correct.

    I'm guessing from what you say that I'm probably using considerably less than 400W - is there an easy way to check what power I'm using?

    I'm also guessing that the higher the power of PSU the less efficient it gets when the computer is in standby mode?

    Its really a lot more complex than I would have guessed. Originally I guessed that the higher the power the better the computer would perform but it would cost more, then realised that the higher the theoretical power it didn't effect the power the computer consumed, now I seem to be getting the idea that the higher the power although it doesn't effect the consumption it does effect the efficiency so it is more expensive to run.

    I also assumed that the higher the power, the more expensive the unit would cost. Yet in this case the 800W is a cheaper than the 500W one, and the 800W one is a make I'm familiar with while the 500W is not (doesn't mean a great deal as I I'm not that familiar with PSU - as you can obviously tell from what I'm writing).

    Any more advice gratefully received.

    Thanks again.
    This is a really helpful post, I didn't realise the 50% part. Just signed up to say thanks
