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. We don't always comment on the packaging of a product, but XFX really excel at attracting the eye within a store environment.
Technically, both supplies have stable regulation and cope well with varying loads, as our crossloading results verify. Ripple results are equally impressive and efficiency levels are also very good, exceeding the 80 Plus Bronze certification they have achieved. Noise emissions are reasonably good with the large ADDA fans keeping the temperatures well within check, even under high continual loads.
As we said last time, this series from XFX is not released to break any performance records, but they are a well priced range of supplies with good internal design and high reliability. UK pricing has not yet been confirmed with us, however as the 650W unit was retailing for £65 you should expect to see the 550W for around £55 and the 450W for £45 or less.
KitGuru says: Quality products at great prices, the Pro Series has been a great success for XFX.
Nice chassis design from these. Pricing looks spot on, if they hold to what you think.
450 would be great for a media center, like the fact they have included two pcie cables even at lower end.
ermm didn’t they discontinue the pro series? I saw some with cancelled notices on uk stores recently.
I think it might be stock, our local pcworld stock the 650w. what store did it say the pro series was cancelled?
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.
They need to bring out a 1500W gold certified supply, just for shits n giggles.
There is no conductive polimer capacitor in these units. The visible ones are all traditional low ESR ELKOs from Nippon Chemicon.
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.
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
Both power supply’s are not Haswell suitable due to new sleep states Intel added to the CPU
