![]() ![]() This is why 12V2 has 5 more Amps at hand than 12V1. 12V2 supplies power to the CPU in socket 2, as well as the 12V required for the SATA drive. If your motherboard has dual CPU's and utilized the 8-pin EPS power connector, the 12V1 power just the CPU in socket 1. Classically, the whole lot is on 12V1 (the "first" 12V rail) and the CPU is on 12V2 (the "second" 12V rail.) A lot of companies then will place the SATA on 12V2 with the CPU or maybe PCI-e or maybe one PCI-e on each of the 12V rails.Īs you understand by now the Silverstone ST60F has four of these 12V rails. Let me explain this first: Usual ATX12V power supplies have two 12 Volts rails. What immediately strikes the eye is the fact that there are four (quad) 12 volts rails, I mean it's fantastic that there are four of them if you decide to do some SLI/Crossfire gaming yet they are 13, 18, 16 and 8 Amps each and that as we'll show later is an issue. Single 120mm cooling fan for quiet operation.Quad +12V outputs and Dual PCI-e 6-pin connectors.600W continuous power output (up to 50?C). ![]() We need a good PSU these days and in the near future probably diesel backed up generators in our gardens! Starting with a 520 Watt PSU today is not really that bad of a specification for today's high-end computers.īy now I think I have been able to make you aware of the point I'm trying to make. With a lot of HD's and extras like active fans and case-mods such as lights, or if simply powering a high-end gaming rig, go for something even higher than 400 Watts. Therefore always choose a PSU with plenty of 'breathing' space for future upgrades and devices.Īt this time I suggest you get at least a 400 Watt PSU for any mediocre PC, where that number was 300 Watts two years ago. Do you have a dual CPU based rig or Dual Core processor? That'll cost you about an extra 80 Watts and then there is additional cooling to ventilate all these "hot" gadgets. However, for every additional HD or optical drive you need to add 10 Watts and that's where the problem nowadays is.ĭo you choose the never ending Guru path of upgrades in the form of SLI or Crossfire graphics cards? Add another 75-100 Watts to the margin we just set. That still leaves plenty of room to play around. The minute you overclock your processor and graphics card, and use the HDs and optical drives, your wattage will rise to about 350-380 Watts and can, at very stressful points, peak even higher. When Windows boots it'll use up no more than like 120-130 Watts. Let's do a little math with an average to high-end PC okay? Take a Pentium 4 3.6 GHz Prescott based PC armed with the now mid-range Radeon X800 XT PE, three HDs, a DVD-writer and CD Writer. Manufacturers really need to take a good look at this problem as it is a growing concern. I already tried to make you aware of the importance of power consumption these days. ![]()
