  • RFI could be an issue if you are a Ham operator

Final Thoughts
This writer likes their games hot and the PSUs cold. That’s what you get with a brick of a pore supply. It generates the power you need to keep drives, CPUs, and GPUs going with power left to spare.

That is what you want in a PSU with enough capacity to handle the load and not have to struggle to keep up. You, could, of course, upgrade to a 1600-Watt Giga-power supply.

But, why bother? 850 Watts will run a game machine that 90% of most people out there will never see in their home without emptying their bank account on it and at this price; it’s not cost effective to go with a larger PSU. The only flies in the ointment are that some users have reported PSU failures that take out their other hardware. Though it is a remote possibility, you need to keep it in mind with this or any other PSU. The other complaint is with the SATA connectors being split. You need to hook your cables up right and be careful with some of the connectors.

Our final verdict is that the PSU is a good unit and will fill all your needs and then some.
