Quiet, Good number of connections and good length of cables
Non so far
Does what I expect a PSU to do.

Experience: 6 Months
extremely reliable, solid build quality, great value, high quality, true wattage
fan sometimes makes a ticking noise
great product, pretty much a re branded seasonic, really quiet but not silent

Works as intended
none so far
Easy to install. No bumps along the way. Quiet.

Experience: 28 Days
No fan monitoring header
Pictures don't match actual unit (as others have noted)
Not much to complain about this unit. It is pretty quiet overall and powers up a modest system with a older i7-860 and R260 card. It has proven to be very stable even during an extreme heat spell we have had lately (ambient temps - 35 degrees).

There are cheaper units at this wattage rating but they won't have the reliability that this unit can provide. Also the current pictures does not match what is actually shipped as others have noted. There is another similar unit that is Gold rated versus the Bronze of this PSU, but is costs a bit more.

Experience: 1 Years

Quality, decently quiet.
Not modular
~Update: Fan makes clicking noise.
This is a Seasonic rebranded PS which means it is good quality. Not modular, and priced higher than comparable power supplies at this wattage, but definitely worth it for a system that's running 24/7 for a few years. Hate MIR's, but process was easy.
~Update: This fan makes a quiet but audible clicking noise. I discovered this after I moved my HTPC out of the cabinet. It drives me absolutely insane and I would NOT recommend this unit. Search for fan noise on this unit, there are others having this same issue.

Good power ratings
Got this PSU for an older build with:
Intel Q6600
Radeon HD4850
Gigabyte P45-UD3R
AData 128GB SSD

It runs almost silent whilst in idle or playing movies. Currently using this as an HTPC, so not much testing with load. However, the amperage ratings look good with 44A on the 12v rail. If this is to be trusted (which online research suggests), this is even slightly higher than the Corsair VX550 that I'm running on my gaming rig. Good quality overall for a $55 PSU.

Experience: 3 Days
Quality, Warranty
Cable lengths are long...
So far I'm loving this purchase. Read up on it being a Seasonic manufactured PSU and I registered it to get the full warranty. The rebate form is quick and easy to fill out online but you have to mail it to get the prepaid credit card as usual. It seems super quiet compared to some of my old units. A couple of little quirks, the unit you get is the TS550 which is fine as it's the same spec, Bronze rated. The warranty is non-transferable. To see the specs sticker you need to pull the PSU as it's on the top of the PSU and not the side.

Experience: 2 Weeks

Work as advertised, quiet
Broke my previous budget PSU and decided to get one better branded and built. Apparently this unit is built by Seasonic which has a good reputation for high quality PSU.

Its quiet even under gaming load. Powers my O/C'd FX-6300 / M5A97 / R7 250 with much to spare.
The cables are wrapped and long enough to be routed behind the case. Lots of connectors, too many for me, but others might need it.
Great buy and recommended!!

Experience: 5 Days

Very reliable yet at a very affordable price. This power supply is manufactured with the best quality by Seasonic.
Some people might struggle with cable management since it's full wired.
This is a high quality power supply, no doubt about it. Reason why I gave it 2 stars is because I received the XFX TS 550W, it seems it is sold under the name of the XFX Core Edition. Both are quite the same, I did not returned it because it served it's porpuse quite right but BEWARE! you might not get the XFX Core Edition, but the XFX TS 550W.

Experience: 1 Weeks

Small clean design. Sufficient cable length all sleeved. Quiet fan
sleeving not the best, received a TS550 instead of a Pro550W
The power supply proved to be quiet at moderate to medium loads. At higher loads, the fan tends to get noisy.

The product description is for an XFX Pro550W (#P1550SXXB9). The product that arrived is a TS550. Looking at the specs of the TS550 (#P1550GTS3X) it is gold certified. This one however has a bronze certified label on the PSU housing. The carton and the PSU housing is for TS series. The actual product specs and the SKU/UPC is for the Pro550.

A couple of weird things with the cabling:(These issues do not affect the functionality of the PSU)

1 X 6+2 pin plus 1 X 6-pin pcie connector for the video card
(The six pin is labeled pcie but the 6+2 has no label).

2 sets of EPS12V cable. One is a single 8-pin and the other is a split 4+4 pin.

3 sets of cables with 3 sata power connectors each (for a total of 9 sata devices). The two cables are of equal length, the 3rd cable is about 6 inches shorter.

Using OCCT 4 for an extended PSU test, the power supply worked without any issues even when stress tested continously for about 2 hours. This PSU will be powering a system that draws less than 50% of its rated 528W +12V output x max CPU and GPU so I'm not expecting any major longevity issues.

Comment: jonnyGURU: So because of slightly better voltage regulation and a more competitive price point, the 550W version of the XFX Core Edition squeaks by with a Recommended award.
Posted by: Shinma @10/19/11
Comment: KitGuru: XFX have rounded out their Pro Series with two very capable units at the lower end of the price spectrum. Both 450W and 550W supplies are well designed with fantastic build quality...
