-Looks cool
-Great quality, rebranded Seasonic PSU
-Not modular
-Mail-in rebate
-Only PCI-e connector
Definitely a good choice for any build not involving multiple GPUs. I would suggest this to anyone building a budget gaming build.
The only downsides are that it's not modular and that it only has one PCI-e power connector..

Experience: 4 Months
 Verified Owner
great quality, nice black brushed finish, netting around cables
none so far
using it for a HTPC, does the job well

Experience: 4 Days
 Verified Owner
Excellent Quality (rebranded Seasonic)
Price (41.00 after rebate)
Cabling rather on the stiff side
Not Modular, but for the price can't be beat
For an office, or a home family machine this is a nice PSU. Won't run a gaming machine but that isn't the intent.

Experience: 1 Weeks
 Verified Owner
Feels high quality
Plenty of cables for
Rebranded Seasonic
Not modular, but at $41 you can't expect that
Excellent PSU for a simple home office build. Quiet, lots of cables for fans/hard drives etc.

Experience: 5 Months
easy to install
good for low budget build
good powersupply for a budget, dont really need all the bells and whistle of a 2000w powersupply

Experience: 5 Days
 Verified Owner
Mail rebate
This PSU is a excellent one for surfing, office, budget computer or even gaming (but carefull, maybe you need better wattage for good video card with). XFX do really good with psu. Ill buy again for my next build.

Experience: 2 Months
- Great quality, reliability and performance packaged into one power box that can power your PC : D
Wish it was modular (there is a modular version but it is more expensive)
A great power supply for any computer that isn't going to run super high end graphics cards.

Experience: 4 Days
 Verified Owner
Great PSU, efficient, seasonic internals
Only one pci-e power connector
Within it's limitations, one of the best!

Great power supply. Runs stable and efficient. Sleeved cables a plus since it isn't modular. My only gripe is that it has one pci-e power plug. Wasn't an issue for me right now, but could be for some. For a 450w psu I dont think you could expect to run sli/crossfire anyways. Only an issue for higher end single card setups.

My system: i5-2500, z77 mobo, 8gb ram, 1 hdd, XFX 7770 OC

Experience: 3 Weeks
 Verified Owner
Cheap with MIR
Enough power for HTPC
Only one PCI-E connector
Seems like an alright power supply so far. Quiet and provides more than enough power for my HTPC. The only downside I can see so far is that it only has 1 pci-e connector and most video cards require two.

Experience: 10 Days
 Verified Owner
Specs look good
Inexpensive if the MIR gets paid
Misleading marketing (see below)
Despite the prominent advertising of "all high-quality Japanese brand capacitors", which is mentioned in the user manual as well, mine has a number of Su'scon and Teapo capacitors clearly visible through the PSU vents as soon as I removed it from the packaging. Those aren't Japanese brands, and I'm not sure they are high-quality. I guess the factory might have made an honest mistake in this one sample that I have, but it doesn't inspire confidence.
Please also note that this PSU has just 1 PCI-E cable. Some reviews on the web refer to 2 PCI-E cables for this model, but mine came with just one.

Below are reviews found on other web sites for this product submitted by customers.

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...
Posted by: Shinma @10/19/11
Comment: The XFX Core Edition 450W is clearly a totally different animal from the 650W, 750W and 850W we reviewed recently. And if I could grade on excessive marketing fluff and incorrect information on the box, I'd drive the score into the ground, but over all it's not a horrible unit. I dare say it
