Scythe Japan unveiled its Gouriki mid-range PSU series. Consisting of 500W (SPGRN-500), 600W (SPGRN-600), and 700W (SPGRN-700) models, the series consists of 80 Plus Bronze-certified PSUs with fixed-cabling. The cables are not sleeved, and the PSU's body doesn't have any paint. It appears, however, that Scythe tried to spin this to its advantage, by referring to it as a design element it calls "Naked Herculean Strength" (not a case of bad-translation, it's literally what Scythe prints on its PSUs).

All three models feature a single 12V rail design, and a compliance/feature-set that includes ATX12 Ver2.3/EPS 12V, OCP, OVP, OTP, SCP, and UVP. A 120 mm fan is employed to cool the units. PCI-Express power connectors include 6+2-pin and 6-pin power connectors for all models. The power connector loadouts of the three models differ only with the numbers of SATA and Molex connectors available. The 500W (SPGRN-500), 600W (SPGRN-600), and 700W (SPGRN-700) models are priced at 5,980, 6,980, 7,980 JPY, respectively (US $72, $84, $96, respectively).
