Recommended power supply unit (PSU) for a new PC build?

Im new here . A few Google searches have shown me that there are many informative and helpful
people on this forum who may be able to help me in regards to the subject matter.

now my question is; I'm attempting to build my first PC and need advice as to which power supply would be adequate for my system. My specs are;

Intel Core i7 2600 processor
Asus P8P67 Deluxe motherboard
8GB Corsair Vengeance DDR3 RAM 1600Mhz
2TB Hard drive 5400RPM
x2 Blu Ray/DVD RW/Light-scribe drives
Nvidia Geforce GTX 560 Ti Graphics card
PC case with 7 Integrated fans (x1 with LED)

Not sure about a sound card as i may use on-board sound. Also, is a CPU cooler necessary as im
not planning on overclocking. All suggestions are welcomed and greatly appreciated.

Do you plan future SLI?

I'm curious, why the 5400rpm drive? That's gotta really hurt your performance.

Thank you for your recommendation, i really appreciate that

HDD Spin Speed is very important, getting a better quality HDD will give a noticeable improvement to things like windows boot time.

I'd recommend the Sanmsung SpinPoint Series ( . The HDD's are well priced and offer great read / write speeds for a 7200rpm HDD.

Getting 2 of those drives and putting them in a RAID 0 config will give you even more speed and improved performance.
EDIT - RAID 0 effectivly combines 2 HDD's into 1 and shares the data between them (in very small strips) this effectivley doubles he speed of the HDD as it read and writes from them both at the same time. (Laymans Terms)

Thanks for clearing that up. Im currently still using a 320 GB samsung drive in my 7 year old PC and have never had the slightest hiccup, so can't deny their quality. As im located in the UK, purchasing from Newegg isn't gonna happen as they don't do international shipping . I should've mentioned before that the main reason i settled for that particular drive is because the cost was within my marigine, and is a reputable quality brand (Seagate Barracuda). The only alternative was Western Digital, which i refuse to touch with a 50 foot barge pole due to their poor standards in quality . Seriously, the internet is littered with people complaining on forums about loss of data due to the hard drives dieing well within warranty

In regards to RAID 0, am i right in saying that as the same data is written to both drives, won't this reduce reliability? Because if one drive fails, the other drive(s) are effectively filled with useless, unfinished data. Seems a little too risky for me . Thanks for the

According to NVIDIA's specifications the minimum power supply requirement for a GeForce GTX 560 Ti is a unit with a minimum of 500 Watts or greater and with a minimum combined +12V current rating of 30 Amps or greater.

Antec High Current Gamer 520W 80Plus Bronze for ~£60 is probably your best bet.

That is exactly right! If you want to improve performance and reliability, you could use a RAID5 setup. it requires at least 3 drives though.

Thank you for the recommendation. I'll have a look on amazon or ebuyer as Newegg don't ship to the UK. Thats such a bummer
because Newegg seem to have EVERYTHING at such great value . Its so true about not cutting yourself short with the PSU, if there's
one thing i know for sure about computers, is that the PSU is the most vital component.

yeh i can be a bit of an efficiency freak at times so the fan would kick in when the systems being strained, and remain idle when its not? Seems
like a great idea and thats something i may definitely consider. Yeah i think im gonna go with either Antec or Corsair as they appear to be of the utmost
quality PSU's. I appreciate your input jtt283

With RAID5, if a drive goes bad, you replace that drive and the RAID5 will rebuild the missing data, kind of like using a parity bit to prevent bad memory.

I am reminded of the old Benny Hill routine about bombs on airplanes: He said that the chances of there being a bomb on an airplane were 1000000 to 1. and the chances of there being two bombs on an airplane were 1000000 times 1000000 to 1. so be safe...Always carry a bomb when you fly!

Raid 5 is extremely fault tolerant. The "parity bit" isn't only on one drive, it is striped across all the drives in the array, as is the other data. and, you are right, if you lose enough drives in the array, you will lose the data. Usually, though you won't lose multiple drives at the same time, and that gives you some time to replace a faulty drive, and rebuild the array. You need to keep a spare drive available for just such an occurrence.
