Chieftec BPS-450S

Sub-$75 Mainstream Power Supply Roundup
By , Patrick Afschar

The 450 W Chieftec BPS-450S is the most powerful PSU remaining in this test after the AXP's untimely death. What first struck us when unpacking the Chieftec was its thick, multilingual manual. An extensive printed manual is uncommon, especially in this price range.

The cables and connectors are not quite as impressive, however, despite being long compared to the rest of the PSUs in this test. Four SATA and three Molex connectors are not enough for even a cheap PSU, especially one with only a single 6-pin PCIe connector. The ATX cable is the only one wrapped in sleeving.
