Cheap, quiet, reliable PSU for i7 and 3 HDDs

[blizeH]

Hi all,

I have an i7 CPU, 8GB RAM, 5750 GPU, 1xDVD and 3xHDDs

I've been looking at the Antec TruePower, BeQuiet and ModXStream and can't decide between them, or rather when I do decide, the price seems to jump up and it confuses me again, so the price on the ModXStream went up £8 just today, and similarly I went to order the TruePower PSU but then realised I can't claim free delivery at Scan.

So with that in mind which PSU would you recommend please, and what wattage?! :-)

Thank you

Always add at least 100 watts for some room so the PSU isn't always at high load.

Personally I would get 550W+. That GPU isn't very power hungry, and the most wattage required in a computer is usually the high end graphics cards.

I would suggest an OCZ, Corsair, Antec because they are the top end range of power supplies, and to be honest you'd be better for money in the long term for a solid reliable power supply.

I myself have a Corsair TX650W, and from looking at my specifications its over kill. But it leaves me loads of room for future upgrades and long term reliability as the PSU won't be working hard.

So I suggest 550W+, or if you plan to upgrade the graphics card to a power hungry one I would suggest 600-650W+.

Unfortunately power supplies are pricey, but you will want to get a decent one if you don't want to be constantly worrying about your PC dying on you. OCZ, Corsair, Antec, all reliable and will last years

RAM doesn't take up much wattage, nor do fans really. Your current GPU takes about 90 watts up, an i7 120-140w (although CPUs and GPUs never really reach their full load, still take it into account).

Google extremeoutvision power calculator (or just google power calculator and its first link) and it allows you to add up all your components and it gives you an estimate on how much wattage you need. Always add 100-200W for room, never go for the minimum

An OCZ ZS 550W can be had for under £50 and should do the job. Even a decent 400W would be fine with your current setup but a larger PSU should give you more leeway if you change the graphics card.

you can try any cool master 500w PSU. their products usually are quiet and working well.
