    Thanks guys.

    I already picked my PSU i was going for, Just needed to make sure it was the PSU for sure. I am probably going for the Corsair HX850. I heard great reviews regarding this model so i'll just have to wait since it is in pre-order.

    The only issue is this is my dad's unit so i'll have to give it back shortly when it comes back from work :( Been running great for over 4 hours now.

    I guess i can still use my 580w until i get the new PSU.

    Sounds like you're in the UK. I emailed Scan and OCUK about their stock status on the HX750, but they said shipments had been delayed. After hearing this I went and pushed the button on a BFG ES-800. Another amazing PSU. It emulates PSUs of different capacities via frequency shifting to always remain 80%+ efficient. It'll come in handy for any future water cooling too, as it can operate happily with 12V only loads, no requirement to load the 3.3V or 5V rails. Sounds like an ideal water pump and GFX card only PSU in a dual PSU chassis.

    Excellent choice on PSU. You'll be pleased with it, and there's a 7 year warranty too, so you'll be building at least one more system round it after your i7.

    PS, please take a hammer to the Hyper PSU, that's how I ended its life before I placed it gently into the bin.

    Thank you very much your support :)

    I thought they might have been delayed somewhat but i guess it will be worth it to hold on it until then as i will get a quality PSU in the process.

    Ebuyer also have them on preorder so i will order from anywhere and just wait, which shouldn't be more than another week surely.

    They said 2-3 weeks, but maybe they were just covering themselves. The US is a much bigger market than Europe, so maybe they diverted stock there.

    Scan, Overclockers and Ebuyer all have the HX850w on pre-order and i know how long i will be waiting.

    I was going to consider the HX1000 as Ebuyer has that instock and could be a decent replacement.

    I am not really sure though. I want to hold it out until this 850w does come out as it seems the best for price/performace choice and being a silver rated PSU.

    If anyone can recommend me a modular PSU i would be happy to consider another one but currently the Review over at HardOCP said the HX850 is probably the best PSU right now.

    As far as modular goes, yes the HX850 is probably the best PSU available, and at 0.16 p per watt, it's great value.

    The HX620W is modular, and a Seasonic design, making it super quiet. It has better noise/ripple figures than the HX750/HX850, but it's no where near as efficient. It's also 0.17 p per watt, making it slightly less value for money.

    I wasn't trying to imply you were doing the wrong thing by waiting. For a modular PSU of such quality it's worth the wait. My BFG came today, and I'm chuffed to bits with it, it's good looking, quiet and efficient, like my ideal woman. It's not modular though, so it doesn't fit your needs.

    Let us know how you get on with it when you get it. I'm buildin a HTPC and efficiency and being modular are paramount. I'd be interested on an opinion of it's noise levels too.

    Yes i will let you know how the PSU is. I think i will just hold out and wait for it to arrive and then i can be sure i made the right choice.
