Product review: Rosewill Quark Series 1000 Watt Power Supply

This is an excellent power supply with enough power for any personal computer. Its capacity of 1000w and it has a large number of connectors (total of 10) that gives lots of room for growth. Its size is 7.25" x 3.5" x 6". Quark 1000 uses heavy duty round cables (i.e. not ribbon cables). All connectors are modular rather than hard-wired. I prefer modular power supplies so the case has only what it needs and thus is less crowded, so this is a big plus.

The power supply can handle motherboards with both 20 pin or 24 pin connectors. It supports two SLI graphics cards. It is very quiet.


(1) One 20 +4 Main plug (modular)
(2) Two EPS12V CPU plugs (modular)
It supports two CPUs. This is useful for server systems, desktops have 1 CPU.
(3) Four PCIe plugs (modular)
It supports four high power PCIe cards, typically SLI graphics cards but there are other cards requirind extra power.
Most PCIe cards use only the power from the PCIe plug, but high performance high performance graphics cards use this plug (e.g. gaming graphics cards).
(4) Five SATA or Molex cable plugs (modular)
They use the same plugs and package comes with different cables that can be used as needed.
4 SATA cables, each with 4 SATA plugs for a total of 16 SATA devices supported
2 Molex cables, each supports 4 IDE drives or FANs

I measured the power supply with a power supply tester and all voltages are within tolerance. The attached video includes screen shots that show the power supply tester output. The top number for each rail shows the expected results, the number below (in a slightly larger font) shows the actual reading. 0.5V is the acceptable tolerance. All readings are well within the tolerance.

This power supply is provided by Rosewill testing and review. Its a good one!
