BFG ES-800 800W Power Supply Review

Output Specifications


Even though this power supply is literally a single +12V rail design with multiple OCP circuits, the layout BFG chose for these rails is quite interesting. However, before we go any further into it, here is the breakdown of which +12V rail is associated with which connector:

+12V1:
- 24-pin ATX
- SATA
- Molex
- Floppy

+12V2:
- CPU

+12V3:
-PCI-E 6-pin & PCI-E 6+2 pin cable #1

+12V4:
-PCI-E 6-pin & PCI-E 6+2 pin cable #2

By looking a bit closer at the rail outputs we can see that almost 98% of the ES-800’s output is available on the +12V rails. We have said it again and again and will say it here once more: having the majority of a power supply’s output on the +12V rails is essential in today’s market. That being said, what we really like about this particular power supply’s outputs is the fact that the PCI-E cables each have 36A (432W) accessible to them while the Molex and SATA connectors are lumped in with the ATX connector. This means that the BFG ES-800 will have no problem supplying what even the most power-hungry graphics card demands since the PCI-E cables each have their own rail. On many other power supplies we see the SATA and / or Molex connectors leaching power away from the PCI-E connectors but not with this one.

All in all, the BFG ES-800 contains exactly what any enthusiast wants: plenty of amperage for the graphics cards as well as for the CPU. If this power supply can hold it together in the performance department, many consumers out there will be looking at BFG’s power supplies with newfound respect.
