Squeezing 1000w into a unit not much bigger than your average ATX power supply isn't easy. OCZ recently tried with their ProXstream unit, but unfortunately due to its dual-layer PCB design, the unit ran very hot and required a rather noisy 80mm fan running at high speed even when idle. Hopefully this won't be the case for the GuardianX, but let's take a look inside the unit to find out for certain:
Two high-quality capacitors and several large wire-wound inductors with heavy guage copper wire can be seen on the left-hand side of the unit, with a reasonably large yellow transformer sitting in the centre just behind a large heatsink. Over on the right-hand side is the Active PFC circuitary (just above the power inlet) and a raised circuitboard contained the adjustable potentiometers.
Three large finned aluminium heatsinks draw heat away from the mosfets and other components, with careful consideration being made to airflow through the unit. Information on the ADDA 80mm fan can be found here, but its basic stats include 43.8cfm at a rotational speed of 3400rpm and a noise level of 40dBA.
Cables & Connectors
Normally talk of budget power supplies conjures up images of un-sleeved cables with ugly white plastic connectors. However, Silver Power have gone to the trouble of sleeving every cable on the GuardianX right up to the final connector in an inoffensive plain black mesh.
Quite a few of the most recently released motherboards still utilise the 4-Pin (P412v) connector, and for this reason Silver Power have included both P412v (4-pin) and EPS12v (8-pin) cables on the GuardianX to ensure full compatibility.
