This kind of PSU will likely have good voltage stability, low ripple, and good longevity (this depends on the capacitors they use). At that point, they can't get away with overly cheap components. If you want to be sure of getting a high-quality PSU, look for 80 PLUS Gold certification. ![]() Although they could still cheap out on some other parts. This ensures that halfway decent components were used to achieve that efficiency. You want at least a PSU that has an 80 PLUS Bronze certification at the bare minimum. This refers to the PSU's efficiency when transforming the 230V/110V to 12, 5 and 3.3V for the PC to use. Always go for mid-range at least.Ī good indicator is the "80 PLUS" certification. Never buy the cheapest model they offer, either. If your factor all that in, it's always beneficial to spend that 20, 30 bucks more and get a good-quality PSU from a reputable manufacturer such as Seasonic or Corsair. It needs to provide stable power, efficiently, in all circumstances, over sometimes many years. ![]() Some boards have a secondary EPS connector for overclocking purposes, that can either not be connected if you don't OC, or connected via an adapter, because the first and second EPS connector will share the load.Ī final word about the PSU: It's one of the last places i would try to save money. I believe they're rated for 300, 350 W (which some high-end CPUs can actually pull). The wires inside are less thick, the plug wasn't designed to transmit that kind of power.įor the main EPS connector on the board, i would always connect a native EPS plug, nothing else. It isnt difficult to pull that type of power with these cpus, so. A molex cable is meant for a couple of hard drives pulling 10W each, not for being the sole power source for the CPU's VRM (voltage regulator module) itself. If your cpu is pulling more than that, then you should plug in the additional connector. The problem with an adapter from Molex is, a Molex cable is not rated for the amount of power that a CPU pulls. Auxiliary power connectors: There are several types of auxiliary connectors, usually in 6-pin form, designed to provide additional power if it is needed. They're already using the lowest-tier OEM to build this PSU, Solytech. The obvious explanation would be to save even more money. So there might be one without an EPS plug, though i wonder why the hell they would release that in today's world. As manufacturers demand smaller interconnects from suppliers, Molex allows them to package circuits in tighter spaces by utilizing smaller pins, terminals and. However, there seem to be several revisions of the PSU. If that is correct, this means you plugged in the wrong one, you need to find the cable with the 8-pin EPS plug at the end and use that instead. ![]() Oh my, this is a cheaper-than-cheap PSU.īut as far as i can research, the Rosewill SL-8400BTX aka the RD400- 2-SB has an ATX 20+4 plug, an ATX12V 4-pin plug, and an EPS 8-pin plug?
