Hey peeps, I had a quick question, I've got a new PC, It was originally going to come with a Corsair 850 TX Psu but instead came with a Coolermaster Silent Pro M850 (RS-850-AMBA-J3) Now the coolermaster seems to be coming in more expensive online, but can anyone give me some advice or opinions about it? was it a shoddy change or 6 of one half a dozen of the other?

Cheers people

It's a FSP Epsilon revisited. Here is a review for his big brother. You can compare it with TX850.
You're OK I'd say.

Oh yeah, you're more than fine. It'll run 850 Watts true just as easily as the Corsair. Both would max out around 900 Watts and still maintain about 80% efficiency.

Now, if it you were suppose to have received the Corsair Professional Series, well, then I would say tell them to send you the right one ASAP. :) But, you're good. Enjoy!
