What Power Supply?

post #1 of 19
Thread Starter 
I was just wondering what kind of power supply would be the absolute safest minimum. This is my build list. I plan on overclocking the CPU to around 3.2Ghz but i dont want to up the vcore too much, i also might want to overclock the GPU. I have the power supply i have been looking at, also right now this build is pushing my budget, i might have to lower down to a $50 video card(8600GT) for now. But if i need a better PS please remember i can't afford a $100 one.

MSI P6N SLI Platinum $140

Intel Core 2 Duo E7200 Wolfdale 2.53GHz $135

CORSAIR XMS2 (2 x 1GB) DDR2 800 $23

XFX PVT88PUHD4 GeForce 8800GT XXX 256MB $120

Power Supply : Corsair 450Watt ( Read review, it could have been labeled as 500 watt, can do around 570 watts before it overloads and shuts down $70

Cooling

ARCTIC COOLING Freezer 7 $27

Artic Silver 5 $6

1 120mm Fan

2 92mm fans

A good 400W PSU should be fine. That Corsair 450W is a very good PSU. Also, $35 Antec EA430W is good also if you want to pay less.

Thansk for the response, i was just worried because i saw that a 8800GT under stress can easily take up 200 watts by itself, and the e7200 takes up around 170watts at full load. which leaves 70watts to run all the other components. I also saw that you need high amperage on the 12v rails if you want to overclock, and the antec only has 17Amps, is that enough?

***Forgot to mention i will be also using 4 IDE PATA devices
2 Harddrives
1 DVD-rom
1 CD-rw
since im being as cheap as possible im using as many of the old parts as possible.

Ideally, Corsair 550vx is the best option so you have some head room in case you add more parts in the near future.

say if i were to only get a 8600GT, would the earthwatts 430 watt PS be good with some overhead? I might not need the 8800GT, since i will be using my PC for video editing, encoding, watching HD DVDs and HD video.

The Antec 430watt will be plenty for the 8800GT.


Stay away from the 8600GT it was a horrible card.

Grunion runs his 3870X2 off just a 550watt and I've run SLI'd 8800GTS' on this 500Watt, 430Watts is plenty

what is a good card capable of playing newer games and HD-DVDs for around $50-60?

I'm going to have to question those numbers. I can't imagine the e7200 needing more than ~100W, maybe a tad more, overclocked at full load. A GT at stock will be ~100W, again a little more ~25% depending on how far you OC it. Adding in your drives and RAM, the Antec 430 or Corsair 450 would be plenty of power for you. But also you do limit yourself when you decided to upgrade in the future. As linskingdom mentioned, the Corsair 550 would a little better choice a year or two from now if you decide to get some more poewr hungry components.

The e7200 is for the whole system with a 8800GTX idling while running prime95 plus that is read at the wall and you need to account for psu efficiency of ~80%. The video card comparison has got to be whole system load again even though they don't state it explicitly in their power consumption graphs. They also never stated how they got their power consumption numbers.
