Chieftec's new line of TASK PSUs range from 400 W to 700 W and carry most of the features we expect from mainstream PSUs such as Active-PFC, electric and thermal safety systems, ERP 2013 compliance, sleeved cabling and a 120 mm temperature controlled fan. Though the entire range  features a 12 V rail, it is important to note that the 400 W and 450 W do not have a PCIe connector and therefore will be unsuitable for most discrete graphics cards, however the 500 W and 700 W versions come with one and two 6+2 pin PCIe connectors respectively
