How much can this PSU support?
http://www.corsair.com/builder-series-cx430.html
Corsair CX430 430 Watt +12 V Rails (1) +3.3 V (20 Amps) +12 V 1 (28 Amps) 80+ Efficiency My retailer is on deal for $30. I'm buying a custom system as a gift for an elderly couple. It's a multimedia PC that will hopefully last them forever (they use a Pentium IV ) Supporting a i5 2320 (95Watt) + GTX550 Ti + 7200rpm (This is a bit imbalanced) OR Phenom II X6 1045T (95Watt) + HD6570 + 7200rpm No OC on anything. I want a safe PSU. not one that barely supports it and has a lifespan of 1 year. More like 10 years. (currently under $400 excluding the HDD/RAM/monitor/keyboard/mouse that I have so many spares of) Thanks |

The PSU you chose should be enough for the AMD system, but not for the Intel.
Good tool for estimating what PSU to buy. http://extreme.outervision.com/psucalculatorlite.jsp btw, I think the builds you have are overkill for the purposes for the elderly couple. If not gaming or GPU compute, integrated graphics are enough. i5 is overkill, i3 is more than enough. As for AMD, X6 is worse than X4 unless they use highly multithreaded software, which is doubtful. |

* AMD's F1 series of APUs, which basically integrates the CPU and GPU into a single package, which is much better than using IGP (integrated graphics). There are now motherboards out there that use those processors, and at the same time allows for future upgrades. * 2gb of memory (4gb to factor in the APU shared video memory) is just enough for everyday use -- web browsing, video playback, word processing, basic games, and bookkeeping. * unless they love to download, I feel that 320gb of hard drive is enough; Seagate and WD drives usually last very long. * To keep the rig stable to last longer, get a UPS, including those made by APC. I remember that the lifetime of a PSU varies from one another depending on how it's being used, especially when factoring in the capacitors' slow deterioration. In this case, 3-5 years should be enough for the PSU if they use the PC for 6-8 hours a day, but it'll be a record if the PSU lasts for 10 years (and I have a 2000-era Compaq Deskpro that's still okay). As far as really solid PSUs are concerned, IMHO this is the ultimate (they're still around for many years): http://www.pcpower.com/index.html BTW, I also used a P4 rig before it was replaced by a new custom-build based around the Athlon II X2 260.

The couple wants to do a lot of things (photoshop/uploading videos/downloading videos/movies). I have no idea what they want to do exactly, and neither do they. So it's really ambiguous for me. (I forgot I used to play Starcraft on a Pentium III lol) |

If they don't game, they still need no graphic card at all. Intergrated will go long way with stuff you described. In fact, I just built a computer for my mum which was also a sort of multimedia pc .. Went with i3-2100, H61M motherboard, 8GB memory and XFX 450W PSU. 8GB because well, it's dirt cheap so .. why not?
I would suggest same if not similar setup for you. If you insist on getting i5 (which you really won't need), at least drop the graphic card out completely. With that money, get a 64GB SSD. for Windows and programs. That SSD will really go long way when you look at the overall performance even for normal usage w/ no gaming.

I used the PSU calculator to figure out what I could put on my computer. My PSU is 620 watts. I factored in a sound card, but I don't have one. Should I get a sound card? I just use sound from the motherboard. I hear that that eats up a little bit of processing power from the CPU, unless I have a sound card. Would it be worth getting?
Also, how do I factor in capacitor aging? The PSU calculator goes up to 50% capacitor aging. Now, my PSU is just a few months old. I have nothing to worry about with it for a few years or several years. I'm just curious, how long would it take for capacitor aging to reach 50% from someone who doesn't use their PC 24/7 (just pretty often) and doesn't game like 8 hours a day every day? How long do you think it would take to reach 40% or 45% capacitor aging?

Besides the cheap PSUs, despite the high wattage they are caliming to have, often (always?) have low power on the 12V rail. Which is where it counts, because this is the main power source for CPU and GPU.
You can basicly consider the maximum load on 12V rails as the defacto power of a PSU nowadays. The other rails will never max out before 12V does. |

Well if it's for the elderly and it's for multimedia then a 500-600w would be better as it's the standard range for this day and age. I'll assume they're hardly going to do any gaming, but more on the lines of internet surfing, word process and maybe movie viewing.
Stick with the Intel CPU as those will last them a long time. I heard the I5's integrated GPU does a great job for processing and editing video.
