XFX Pro Series 450w and 550w Power Supply Review

The 7 blade 120mm fan is a ADDA AD1212MB-A70GL ball bearing unit which is rated at .33A, 2050 rpm while generating 38dBa of noise and pushing 80.5cfm of air. The 650w, 750w and 850w models in this series use a 9 blade 135mm ADDA ADN512UB-A90 unit.

XFX use high quality Japanese capacitors which are rated to withstand up to 105c. These are conductive Polymer Aluminum Solid Electrolytic Capacitors to help improve operational stability under continued load conditions.

There are also several rows of heatsinks seperating the components which receive air flow from the fan above.  The XFX PSU is supplied with automatic output protection to ensure no damage occurs. This includes Total Power Protection (OPP), Over Voltage Protection (OVP), Over Current Protection (OCP), Short Circuit Protection (SCP) and Over Temperature Protection (OTP).  The cables are sleeved well into the chassis, which helps to ensure no long term damage by fraying. The cabling is well routed and organised with ties.

  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
