Hello,

I'm getting together a parts list for my first homebuilt pc and I'm currently looking at PSU's around £65 or less (£50 ideal)

I looking at having an i5-3550 or 3570, with possibly a Radeon HD 6850 or 6870.

I've seen the Corsair Memory 700W GS700, that looks pretty good, was a little over the budget but I may be able to get it cheaper somewhere.

If anyone can recommend any others that would be helpful.

:)

I see that the Corsair GS700 is £70-75. If you can get for £65 then its good. But I would prefer the TX650 if available for the same price.

If you don't care about it being modular, I agree with randomkid that the GS700 is an awesome PSU. My buddy has had one in his rig for a while now.

A system with a single HD 6870 requires a 500W PSU with at least 32A on the 12V rails and two 6-pin PCIe power connectors. The GS700 is a good PSU but is way overkill for your build. The XFX Core 550W has 44A on the 12V rails, more than enough connectors for your system, is an outstanding PSU made by Seasonic (arguably the best PSU mfr) and has a 5yr warranty: http://www.scan.co.uk/products/550w-psu-xfx-pro-series-...

Thankyou for your suggestions and information.

With the PSU choice of modular or not, I've read on some reviews that some Modular psu's have quite chunky wires so it's hard to place them in some cases. Do you know if a modular psu would be fine in a case such as the Coolermaster CM Storm?

Also, what does it measn if a psu has 'Bronze' in it's title?

Sorry for the newbie questions.

The XFX 550 looks a good psu and is Well within my budget too. I will write that one down as a viable option. Thankyou.

You're welcome...and questions are always welcome.
Efficiency and 80+Bronze: PSUs convert AC from a wall outlet into DC power to be used by the PC. PSUs don't convert 100% of the power from the wall into usable power for the PC; some of the power is lost in the conversion process (mostly in the form of heat). The more efficient a PSU is, the less power is lost in the conversion process. 80+ is a certification process for PSU efficiency with multiple certification levels from simply 80+ all the way up to Titanium. A PSU has to maintain certain efficiency levels at 20%, 50%, and 100% PSU loads. For a little bit more info: http://en.wikipedia.org/wiki/80_PLUS

You should have plenty of room in any of the CM Storm series case to run/manage cables with a modular PSU. I've never had a 'chunky' cable issue with any of my modular PSUs.

Glad I could help!

Ahh I thought it was something to do with efficiency, thankyou. I also read the link too which was helpful.

This one looks good too, modular with 80+ bronze and 5yr warranty, and just outside my budget. I don't think this one has a coloured fan like the Corsair GS range though(?) (going with Black and Red theme) :)

Awesome PSU that helped to put Corsair on the PSU map for quality PSUs. Review: http://www.jonnyguru.com/modules.php?name=NDReviews&op=...
I think that the XFX 550W is a better deal, but it isn't modular; good cable management/hiding can easily get them out of the way.

I don't think that the VX series or the XFX comes in a black/red theme...you could always throw in some red LED strips instead of red components.
