Corsair power supplies have earned many accolades from the enthusiast press, and they tend to be priced accordingly—rather high, that is. With its freshly introduced Builder Series PSUs, however, Corsair seems to be trying to attract more cash-strapped shoppers. The cheapest unit in the new series, the 430W CX430, has a scant $49.99 suggested retail price... and Newegg currently offers it for $29.99 after a mail-in rebate.
Hitting that kind of price point involved cutting some corners, though. The Builder Series CX430, CX500, and CX600 all have only two years of warranty coverage, and I'm not seeing an 80 Plus badge anywhere on their product pages. Corsair does claim energy efficiency of "up to 80%," though.
All three Builder Series units also have single 12V rails and 120-mm temperature-controlled fans. Corsair says it's designed these units for systems with "single GPUs," so you'll only find two PCI Express power connectors on even the 600W CX600. (Keep in mind that mid-range cards like the GeForce GTX 460 require a couple of those connectors.) Corsair quotes suggested retail prices of $64.99 for the CX500 and $74.99 for the CX600.
