Three manufacturers sent us their new power supplies for the 500/550 watt segment. From Antec we received the VP550F, Cooler Master sent us the 500W B series model and Nexus provided their new NX-5000 V1. We will compare them to 22 other recently tested 500/550 watt PSUs.
500 watts is a popular segment these days. It's more than enough for powering an Ivy Bridge or Haswell CPU and a single mid-range or high-end graphics card. If you plan on using multiple GPUs and overclocking, you will need a more powerful PSU.
There's a lot of competition in the pricing in this segment. Spending money on a decent PSU is not a small part of the total price of building a capable PC system. For this reason manufacturers try to keep prices for their 500W PSUs as low as possible. The Antec VP550F is pretty affordable with an average price of € 63, the Nexus NX-5000V1 is even cheaper at € 58 and the Cooler Master B series 500W only costs a mere € 44. We'll find out whether the manufacturers cut too many corners, so keep on reading.
