    be quiet! System Power 8 600W

    A quality PSU for £40. Where's the catch?

    Good for a cheap build

    Nah, I'd rather get a gold or platinum fully modular PSU. No point in spending peanuts on your PSU...

    I remember spending similar on a 430w used bequiet years ago, if building the same machine now this would be a no brainer.

    I've often been asked to build entire rigs on a £300 budget. Which fully-modular 80plus Platinum PSU do you recommend I use for such a build?

    More to the point it's nice to see a decent power supply for less than £10/100W. The 400W version could be very interesting indeed...

    Re: be quiet! System Power 8 600W

    Given that a typically modern system would idle at 80W or so, an additional 25 watts is consumed at the wall if going for a PSU of this ilk..
    I think the choice of a PSU should be based very much on its intended use. For a machine that is on 24/7 a premium PSU could save about £25 a year, £75 over the period of its warranty. If you only turn it on when you need it however, this appears to be much better value.

    looks a good option for cheaper and mid range builds. good psu's too.

    Compare the noise with a Seasonic PSU and then we'll talk!

    The review is certainly flattering, I'll be sure to buy one on my next order from Scan and see how it performs. I like cheap and good. Hate cheap and nasty.

    More the point is that it is important not to over-specify the PSU power rating. Ideally they should be matched to run at around 80% of its maximum power rating to achieve maximum efficiency.

    You're simply not going to able to afford a fully modular PSU with that budget. You'd have to opt for a 80+ gold rating PSU.
    I'm personally a big fan of EVGA PSUs - they have always served me well
    Try the:
    EVGA 650 W G2 GOLD 80+
    EVGA Supernova 650W G1

    But granted these are expensive for that budget but you have to educate people that there is not point of buying a PSU that is less than gold rated because of power efficiency and fully modular because it is a lot easier to upgrade and neater. A decent PSU can last multiple generations and CPUs and GPUs and is definitely worth the investment. Don't cheap out on the most important part.

    If you go fully modular, you might as well go custom cables. I see no point otherwise as there are some cables, that you will always need, that always have the wrong length

    I usually over specify the PSU so that the fans aren't going like the clappers as I like a nice quiet build. Also, if you need to change a component which takes your 80% used PSU up over 100% forcing you to buy a new PSU, that is probably all the cost savings of being on the peak efficiency blown in that re-purchase cost.

    Well ... yeah. Exactly. There's no point saying "spend more money on your PSU" if you don't have more money to spend. My friends / customers aren't going to thank me for making them a slower PC just because I've spent a big chunk of budget on a highly rated PSU.

    Check out the at wall power draw of a Skylake i3 with a GTX 960: http://hexus.net/tech/reviews/mainbo...g-aura/?page=7

    That's using a 760W PSU - massively overspecced, operating at less than 20% of maximum even under a gaming load. And that's the whole point: a lower rated White supply would be running at a much greater percentage of its maximum load, so would have a similar net efficiency.

    besides, even assuming that a more expensive PSU is, say, 10% more efficient at that load (e.g. 90% vs 80%), it would save you a maximum of £10 a year if you were playing games 24/7 on that machine. Most people turn their computer off from time to time, and use it for web-browsing/email/facebook/etc which the computer will run at idle. And the same difference at idle 24/7 would only be £3 a year. Not such an impressive sounding saving, is it. And if the computer gets turned off for 8 hours each night, that drops to £2 a year. So maybe saving £20 by getting a lower rated 80+ white PSU isn't such a bad idea after all....

    And as an aside, if someone's asking me to build a computer for them, the chances are they aren't then going to invest heavily in upgrading it themselves. And if I'm building it, it's unlikely to have a windowed case, so the neatness of the wiring is moot. So fully modular would save me 3 minutes during the build and a couple of cable ties to keep spare wires out of the way.

    Yeah, I suppose your right - if you're building for others they aren't likely to upgrade, but if it is your own personal rig I would recommend Gold + and fully modular. To me spend 1/10th of your budget on your PSU is a bargain - check my build out here - https://uk.pcpartpicker.com/b/MrjcCJ

    The budget for your monitor is more than most people would spend on an entire system!

    Try working out what how you would spend £400, including a copy of Windows and a Monitor. Suddenly a semi modular Novatech Powerstation at £35 for 500W looks like a luxury, the extra fiver to get up to your recommended 1/10th of budget is unlikely to get you gold rating or full modular, and might be the difference between GTX750 and GTX950.
