5 out of 5 eggsXFX BEFX 850W 1 year+ Update

This review is from: XFX P1-850B-BEFX 850W ATX12V 2.2 & ESP12V 2.91 SLI Ready CrossFire Ready 80 PLUS GOLD Certified Full Modular Active PFC Power Supply

Pros: Well its been almost 2 years since I installed this PSU into my system, I have not had any issues what-so-ever with this PSU.

This unit has sustained 4 power surges (protected by a Monster Power Center) and is not only surviving but kicking *** like it was never an issue.

After almost 2 years of gaming abuse this PSU is still registering the following.

12v Rail = 12.055
5v Rail = 5.017

All of these together still make this PSU near Platinum efficiency ratings!

Cons: None

Other Thoughts: One of the best PSU's I have ever owned thus far, I also have not heard any coil wine but that could also be because I am running 6 old Thermaltake 97.6CFM 120mm fans that each make 36 decibels of noise.

*NOTE TO XFX, KEEP MAKING/RE-BRANDING QUALITY PSU's LIKE THIS!

Manufacturer Response:

Thank you for the great review! We are happy you are pleased. Note Taken, we intend to!

If you have any questions for us here at XFX, please visit xfxsupport.com or email us at neweggsupport@xfxforce.com.

Thanks

4 out of 5 eggsNice PSU

This review is from: XFX P1-850B-BEFX 850W ATX12V 2.2 & ESP12V 2.91 SLI Ready CrossFire Ready 80 PLUS GOLD Certified Full Modular Active PFC Power Supply

Pros: Lots of Power
Modular

Cons: The modular aspect can be a little frustrating. Instead of having short cables all clearly labeled that you plug extensions into, you plug all the cables directly into the PSU.

While there is some labeling on the PSU, it's not really direct and it took me a little bit to figure out what goes where.

Another issue is the SATA power connectors. They are pretty much a mess. I have some bottom case mounted SATA drives and due to how the cables are set up, it was impossible to plug them in. I had to move them somewhere else so there was room for the cables to be plugged in.

Other Thoughts: Not a bad PSU, modular and the fan is pretty quite. Would have been a bonus if there was lights on it.

Manufacturer Response:

Hello Jeremy and thank you for the review.

We're sorry it doesn't come with lights, but if you prefer to customize your case, there are plenty of 3rd part led lights that would quickly adapt to the sata and molex cables as needed.

This review is from: XFX P1-850B-BEFX 850W ATX12V 2.2 & ESP12V 2.91 SLI Ready CrossFire Ready 80 PLUS GOLD Certified Full Modular Active PFC Power Supply

Pros: Fully Modular, Silent operation off load, reliable

Cons: None

Other Thoughts: I've enjoyed this unit for some time now. It's very efficient and I love the "hybrid" fan control. This unit has powered an AMD FX-9590 and R9 290x for some time now with out complaint. Another reliable XFX product and satisfied purchase.

5 out of 5 eggsGenerally a great PSU

This review is from: XFX P1-850B-BEFX 850W ATX12V 2.2 & ESP12V 2.91 SLI Ready CrossFire Ready 80 PLUS GOLD Certified Full Modular Active PFC Power Supply

Pros: What drew me to this PSU was its looks and its rating. The looks didn't matter too much while I knew my power goes out quite often so the gold rating was looking pretty good! It just went through its first power outtage and my PC woke up without a scratch!

Cons: None so far

Manufacturer Response:

5 out of 5 eggsExcellent Power Supply

This review is from: XFX P1-850B-BEFX 850W ATX12V 2.2 & ESP12V 2.91 SLI Ready CrossFire Ready 80 PLUS GOLD Certified Full Modular Active PFC Power Supply

Pros: I've had this power supply for about 6 months now, and it's fantastic. I had never used a fully modular power supply before this one, and they are amazing. This one came with every type of cable that I needed, all of them are of adequate length for my full size CM Storm Stryker, just an all around great power supply. Runs cool, plenty of power, never even had the slightest little hiccup with it.

Cons: I really can't think of anything

Manufacturer Response:

Thank you for the great review. We appreciate the positive feedback.
