| 774201 | 2009-05-15 19:15:00 | Can anybody suggest how to determine the correct size power supply, watts that is. When I originally replaced the PSU in my six year old Gateway a year or so back, I put a 350 watt version in. Though I can't remember exactly what size the original was, I do remember the 350W version was significantly larger than the original. And, when I shopped for it on-line at the time, it seemed to be about in the middle of the road as far as capacities available. I just replaced the PSU again, and went for a 350 W model again. But, when I went shopping for PSUs on line this time, it seems like the average size has shifted up somewhat. My 350 watt model seems to be nearer the low end of the range available. They come in sizes anywhere from 250W to over 1,000W. SO what determines the right capacity? In my case its a Pentium 4 processor, and it has two hard drives. Is this what determines power demand? |

| 774203 | 2009-05-16 00:18:00 | I think it depends on what you use it for like how busy will the CPU be and other bits and for how long. 450-500W might be a good minimum, more is good. In general with electronics power supplies wear out esp. if overloaded. | Ofthesea (14129) | ||

| 774205 | 2009-05-16 00:34:00 | It just depends on the power requirements of the total components in the PC. A 125W CPU is gonna use more power than a 89W CPU etc. A GTX295 is gonna use more power than a TNT2. | inphinity (7274) | ||

| 774208 | 2009-05-16 06:29:00 | For a PSU I'd recommend a Corsair modular one, the ability to remove the cables you don't need to use makes the case so much tidier and easier to work in. | WarNox (8772) | ||
