5.0 out of 5 stars XFX Core Editon 550w PSU (6 Months later) 4 Mar 2013
By Steve
I first built my PC in August 2011, which consisted of fairly low end parts and a 450w generic 5 psu.

However, I upgraded my GPU and CPU (about 170w extra load) in March 2012
Then the problems started, constant BSOD's, Unstable OC's and stupid voltage ripple out of ATX12v Regulations.

Under load the CiT 450w psu would drop from a measly 11.6V at idle to 10.8V under load, oh dear.

I was just playing a game and the pc just shut off, not happy (September 2012)

10minutes later, fire up PC and smoke.

I purchased the XFX PSU to replace it and boy was I impressed.

Good sleeving, Nice looking PSU, 44A on a single 12v rail from a 550W!

6 Months on, PSU is very quiet (under a 400-450w load) (Phenom X4 955 OC @ 4.0Ghz and Radeon 6850 OC at 950/1100)

Idle:

+12V - 12.1 - 12.2V
+5V - 5.09 - 5.14V
+3.3 - 3.35V

Load:

+12V - 11.98 - 12.05V

Holds its 12v very well even under a fair load, great psu.

All in all, I spent 30 originally on Case + PSU, bought this for 50 and a new Zalman Z9 Plus to go with it totaling with express delivery @ about 100

Awesome Job XFX (also have 2 of your graphics cards:)

5.0 out of 5 stars Silent and powerful 8 Oct 2012
By Scampo TOP 500 REVIEWER VINE VOICE
Vine Customer Review of Free Product (What's this?)
This new PSU has been running for well over a month in my son's Asus P8P67 i5 computer and it's proving to be an excellent and very quiet power supply.

It was easy to fit indeed, given the many connections that have to be made. Here are some tips for those who feel trepidation in doing this:
i) it's very straightforward so don't feel worried but do be quite sure you disconnected the mains plug before opening the PC; you'll need to remove both sides and possibly the top, too in order to remove the old PSU and fit this one;
ii) remember to discharge any static in your body by touching some bare metal of the computer case now and then while working as a static spark on any of the delicate electronic chips could ruin it;
iii) a good idea is take a few photographs of the motherboard before starting on the job, noting where each and every plug from the power supply goes, if in doubt write this down, too.

Some people have mentioned the cable length and I can't imagine why because they were all plenty long enough for the case - which was a typical one for a desktop PC, the excellent Coolermaster Silencio 450. All in all - there's not much to be said - it works extremely well and is very good value indeed. Highly recommended.

5.0 out of 5 stars Decent quality power supply 14 July 2011
By Johnym
Verified Purchase
Pretty decent for the money. I originally bought the 650w version on the strong reviews I read and what a disappointment that was, it literally sounded like a worn out hair dryer with a nasty rattle. If you're after a quiet quality power supply for a mid spec rig then look no further than this.

Cable length may be an issue if you have a larger case with the power supply mounted at the bottom. The 4 pin cpu power connector is a tad on the short side.

1.0 out of 5 stars faulty unit bad xfx service 9 Nov 2012
i happened to have a faulty unit which happens every so often it went in the first month of ownership. the actual unit it self did everything i wanted it too it came with a 3 year warrenty so i have sent it off and am waiting a new or fixed one.
product it self is 4-5 star

the reason why i have given this one star is the xfx customer service.... here are a list of problems:

couldn't create a support account with a Hotmail account so had to make a new email address.

there is no number you can call and deal with an actual person (they have a support line 60p a min but will tell you to open a support ticket).

registration problems wouldn't except my product code ( supposedly a common problem) which eventually i managed to get working no idea how. until then they were unhelpful until i registered the product.

as soon as i finished going threw the process the answer was send it back to where you bought it from which frankly they could have just told me that at the start.

i spent awhile jumping threw there hoops ( about 3 days of correspondence) if anyone has to go threw this process i would advise to contact the seller or amazon. xfx customer service is not good.

so product itself good but xfx are not good.

hope this is helpfull.

4.0 out of 5 stars 2-pin plug! 9 April 2014
Verified Purchase
A great power unit but would be good to know, before buying, that it comes with a 2-pin Euro plug. Luckily a friend had a spare UK standard power cable, so it was OK, otherwise it would have been a bit of a pain. Having now trawled through other reviews, I see that other customers have noted this issue... please make it clear in the product details/description.

5.0 out of 5 stars Great 27 Mar 2014
By Joshua
Verified Purchase
I originally brought one of the cheap PSU's with the red fan. DO NOT BUY THOSE. THEY ARE AWFUL DIED AFTER ONE DAY OF USE. I have a AMD FX8320 and a Asus AMD Radeon 7790 O CU II. and all the other things that you normally have in a pc and this PSU is perfect. I can hardly hear it

5.0 out of 5 stars Bags of connections! 14 Mar 2014
Verified Purchase
Went for this PSU as a result of much research on mid-power units. A shed load of 'flying leads' .... more than enough for most modern PC's - nice unit - a proper power supply with good build quality - does what it says on the tin!
