Silver Power GuardianX 1000w SP-1000E ATX PSU

Internals & Cables

Internal Components

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:

Apart from the large quantities of white glue around some of the components, the insides of the GuardianX are extremely well arranged and not too overcrowded.

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.

The sleeving job is of high quality, with fabric tape holding the sleeving in place and black heatshrink keeping everything tidy. Unfortunately the sleeving doesn't extend inside the PSU - instead stopping around 5cm short. This may have been done to allow greater flexability of the cables right from the base of the unit.

With new graphics cards hitting the market that make use of the 8-Pin PCI-E connector it's good to see that Silver Power have provided two connectors that can be used in this format. For those of us who require 4x 6-Pin PCI-E connectors for configurations such a dual 8800GTX grapics cards, the 8-Pin connectors can be reduced to 6-Pin by simply snapping away the extra two blocks at the end of the connector.

The GuardianX comes with a 24-Pin ATX connector and no way of reducing the connector down to 20-Pin. People wanting to use this unit on an older style 20-pin ATX motherboard will need to purchase a 24-Pin to 20-Pin connector separately.

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.
