Corsair psu are good, and I've got them in most of my pcs, but they have so many. I have trouble pick one over another my-self. I know they have a help guide but it does not explain the "why" its better or what function it has over another very clearly.

I phoned scan before buy just to check just to be sure.

_alias, what in particular do you find confusing about the line-up? It's always useful to get feedback as it helps us explain the range better going forward.

Briefly, CX is entry-level; TX is enthusiast spec (uprated components, 50C rating etc) but with captive cables; GS is similar to TX but with switchable lighting; HX is enthusiast spec but modular and often slightly higher efficiency (Bronze/Silver, and a bit longer warranty); and AX is the flagship fully-modular range - latest technology, 80 PLUS Gold etc.

Thought the TX was the better-than-budget line, with AX at the top of the range, and HX somewhere in between (seemed to be a degree of overlap betwixt HX and AX to me).

Probably very sensible - always found the Scan boys n' gals very helpful.

Agree with the positive marks for Corsair - got an AX750 myself in December and it's proven to be a pretty solid performer so far. This is my first Corsair - used to use Enermax exclusively but last two PSU's have been Seasonic, moved to Corsair this time because of the better warranty than the equivalent Seasonic. Very impressed with the total package - including a case badge (which didn't stick), a good selection of cables along with a bag to keep the spares tidy and a separate fabric bag for the PSU (which was ideal for protecting my netbook!)

Only downside of my AX750 is that it's accoustically noisy - not fan noise or anything normal, but instead if the system gets stressed it squeaks and hisses - sounds like someone rubbing bubblewrap. I'm not sure whether this is a bad thing or not, but I've not noticed any drop in voltage etc from motherboard monitors when it does this, plus it's not a loud or particularly annoying noise. One of these days I'll get around to contacting Corsair technical support and see whether I need to make use of that nice long warranty, or whether this is just "one of those things" and just ignore it unless it breaks.

You might be describing coil whine, which could be coming from the motherboard, or graphics cards. If it's the PSU then we will replace it, if you talk to your reseller or go via the Corsair site.

There is some overlap with HX and AX, as both are very high quality, efficient, and modular, but the main differences are that AX are fully-modular (HX semi-modular), use the latest technology, and are 80 PLUS Gold.

Out of interest, apart from the improved efficiency are there any other improvements to the second version of the current CX series??

Officially speaking, I can't officially talk about alleged second versions of CX. But since there's a thread on JG, and they're listed on the 80 PLUS site...

It's mainly small component upgrades to meet (though actually they exceed) 80 PLUS White. They are already solid, stable units with good ripple/noise, and the ability to deliver their label rating reliably.

Hello blackberd, Its was when I was looking at the mid range psu units (Non-modular) I got abit confused.

Tbh though I've built a few PCs, I never really understood why I had to buy an more expensive PSU over a cheap one (always have done though), other than quality. I since found out that AMPs are really important lol.

Going though the mid range PSU, this may be scans indirect fault but i give you this example.

HOT SELLER 650W Corsair CMPSU-650TXUK TX, 86% Eff', SLI/CrossFire, 37dB, EPS 12V, 120mm Quiet Fan, Single Rail

HOT SELLER 550W Corsair CMPSU-550VXUK VX, 80 PLUS, 85% Eff', SLI/CrossFire, EPS 12V, 120mm Fan, 5 Year Warranty

Going through the web site and comparing them, the LN20299 looks like the better model. So why is the 550 more than the 650?

sorry for later reply

The 650TX is the better model (though the 650TX V2 is better still). It's probably just a pricing quirk due to when Scan ordered stock / exchange rates at the time etc.
