AMD Athlon2 640 x4, but am upgrading Phenom II X4 965 Black Edition 3.4GHz
Corsair xms3 8GB 2x4 1066mhz
xfx radeon HD6850 df
x-fi extreme music
1x1TB hitachi
Coolermaster elite 335 case
these r what i have to choose from unless any suggestions
OCZ 750W Fatal1ty Series Semi-Modular PSU - 4x PCI-E.. | Ebuyer.com
Coolermaster GX 750W PSU - 6x SATA 2x PCI-E 80plus.. | Ebuyer.com
XFX Pro 750W Core Edition PSU - Single Rail 9x SATA 4x.. | Ebuyer.com

Here is a good PSU calculator that is more detailed than most. I suggest buying at least 30% more than you need. It allows for upgrades, compensates for aging, and will make your PSU last longer because it doesn't strain it. Read the user feedback on several sites to help determine which brand to buy. Personally, I prefer Corsair, Antec or Seasonic. Modular makes for an easy build and a much more clean look, but also cost a little more.

Most of the connectors are standard. Check the motherboard. It will tell you whether it needs a 20 pin or 24 pin connector and whether it uses a 4 pin or 8 pin CPU power connector. Most power supplys will list the connectors and most today come with a 20+4 connector so it can be used for a 20 pin or 24 pin MB connector. Most of the rest are standard sata and molex type connectors. Just look at your graphics cards power connectors and make sure the PSU has those connectors. But you can also get adaptor cables for a graphics card that will connect to a molex connector, But I prefer the connectors to be on the PSU. I don't know if it makes that much difference, I just like it that way.

PSU connectors are standard, although the auxiliary 12V connector might be either a 4-pin or 8-pin depending on the motherboard. As regards wattage, you should be OK with that, although it won't do any harm to fit a PSU of greater capacity, particularly if you might be considering upgrading your system (adding extra HDDs/SDDs, etc).

This 750W alternative is less than £10 more expensive than its 650W cousin.

You're welcome. :)

The 1x4+4 pin cpu+12v connector indicates that it is a single cable to the PSU, and that the motherboard plug on the cable splits into two to enable the same cable to fit either a 4-pin or an 8-pin socket.

In the same way, the 2x6+2 pin PCI-E enables upto 2 cards to be supported that require either a 6-wire or 8-wire auxiliary power connection. There are some cards that require 2 such connections, although I'm not sure whether this can be supplied by two connectors from a single cable.

Hijacking your own thread, eh?

The controller in the external drive is probably USB2, so you'd get no advantage.

Even the fastest HDD will not saturate a USB2 interface, so you will not get any benefits from connecting it with a USB3 cable. In addition, although the USB3 sockets will accept USB2 cables as well as USB3 ones, the same is not true of the reverse, so it is extremely unlikely that a USB3 cable will fit your external enclosure anyway.

Assuming that you do have an enclosure that accepts a USB3 cable, you still won't get an increase in speed when using a HDD due to it being an electro-mechanical device. For that, you require an SSD, and even those will not saturate a USB2 interface (although they are getting closer).

Also ensure any PSU you buy has at least 2 12V rails. I had a 600w ezcool which had only 1 12v rail and it failed big time as it couldn't supply the necessary amps. I now have an OCZ which has 4 12v rails each supplying 18A giving me 72A in total whereas the excool could only manage 25A with the same wattage. Amps are far more important these days.
