You can spend several hundred dollars on a high-end power supply if you really want to, and have a need for tons of wattage. But for most systems, there isn't much point. If you're looking for a decent option without breaking the bank, there is a 500W EVGA model on sale for just $30.
That's the upfront cost—you don't have to punch in a promo code or mail in a rebate form. Both Amazon (opens in new tab) and B&H Photo (opens in new tab) have this particular unit on salee (EVGA 500 B1), so take your pick.
Either way, you're getting a 500W model with 80 Plus Bronze certification. This is a fully wired model (as opposed to modular or partially modular), but that's expected at this price for this wattage from a name brand vendor.
