Thanks to its modular nature, installation of this PSU was a breeze, but for me, with all the components in my PC it still means I have to use almost every cable. Additionally worth noting – this PSU is not that large and will work in all ATX setups.

Test System:

• CPU – AMD Phenom II @ 4.12GHz
• CPU Cooling – Custom watercooling kit
• Motherboard - MSI 890FX-GD70 (as supplied by MSI)
• GFX Card – nVidia GTX280
• PSU – On Review
• Sound - On Board
• Memory - OCZ Platinum AMD edition 1600MHz DDR3 CL 7-7-7-24 -  Supplied by OCZ
• Disks – 2x WD RE3 1TB – Supplied by WesternDigital, 4 1TB Seagate barras and Patriot inferno 120GB SSD (supplied by Patriot)
• Optical – pioneer sata DVD RW
• Case – Silvertone TJ10
• On Review – Silverstone ST1000-P modular PSU

To test the Silverstone ST1000-P PSU, I first took the voltage levels from the different connectors (as listed in the chart below) whilst my system was idle (using a digital multimeter), then took the same readings whilst my PC was under load.

Load was simulated by running Afterburner (for GPU), Orthos (For CPU), AVG Free Virus-Scan (for HDD). Additionally, I turned all my fans up to 100%. I also ran a few burn in tests and 3Dmark a few times just to see if I could push it higher. We could use various monitors to monitor the wattage from the wall, but chose not to as the 3 different testers I ordered were all reporting different results so I decided until we have a better way to test actual output and wall output I would omit this from this test.

We can see here that the Silverstone ST1000-P has very little variation on the rails between idle and load, which is excellent in every way and proves the voltage regulation is implemented very well on this PSU, also worth noting is it is by far the most silent 1000W PSU I have had in my rig for a long time.
