XFX Pro Series 450w and 550w Power Supply Review

XFX packaging is always very stylish and the Pro 450W box uses identical artwork to other units in this range.

Inside are 4 mounting screws and two power cables, one for the European market and the other for the UK market. They also supply a well written manual with a basic overview of the 450w and 550w power supplies.

The supply is encased in soft foam for added shipping protection. As this is not a modular design all the cables emerge from the chassis and are wrapped with a heavy duty cable tie.

The XFX Pro 450W power supply is attractively designed with the name of the product on the sides and a large 120mm fan which takes centerstage at the top. The XFX paintwork is a matt finish which doesn't mark easily and maintains a clean looking appearance, even after rough handling.

The front of the supply is fully vented to aid with cooling and to the left is a power switch, XFX badge and power connector socket.

It can deliver 34A to the +12V rail which is quite impressive, especially considering the modest output.

PCI-E 6+2pin x1 fixed

SATA x6 fixed (two cables)
MOLEX x6 fixed (two cables)
FDD x1 fixed

For a model at this specific power output there is more than enough connectivity to sate audience demands. The cables are fully sleeved and high quality.

  1. Nice chassis design from these. Pricing looks spot on, if they hold to what you think.

  2. 450 would be great for a media center, like the fact they have included two pcie cables even at lower end.

  3. ermm didn’t they discontinue the pro series? I saw some with cancelled notices on uk stores recently.

  4. I think it might be stock, our local pcworld stock the 650w. what store did it say the pro series was cancelled?

  5. Nah, not for me, modular all the way, the system builds are a mess with all these leads inside. no amuont of routing sorts it.

  6. They need to bring out a 1500W gold certified supply, just for shits n giggles.

  7. There is no conductive polimer capacitor in these units. The visible ones are all traditional low ESR ELKOs from Nippon Chemicon.

  8. I purchased my XFX Pro 450W power supply in January 2012. It’s been working fine. But a comment:
    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.

    Please also note that my PSU has just 1 PCI-E cable. Some reviews (including the one on this site) refer to 2 PCI-E cables for this model, but mine came with just one.

  9. this was a big disappointment for me! I’ve got my new pc at home and when powered up i almost hit my head in the roof from the noise! i stop every fan of the case and find out that it was the power supply (the 650w version). it covered the noise of my old crappy 5 years old pc that sounded like a jet already … today i will get it back and currently i researching to find an other silent one. i guess a bequiet or coolermaster silent pro series

  10. Both power supply’s are not Haswell suitable due to new sleep states Intel added to the CPU
