Earthquake is right. Plus power supplys have many different ratings. You can have a 700 watt psu that has crappy rails and will work terrible next to a 500 watt that has high rails. Same thing with efficiency. Its hard to go off deciding based strictly on wattage.
Maybe it's just me, but I find it irritating to have a PSU go out on me. It's usually good practice to upgrade your PSU when you upgrade the CPU/GPU. Besides, a decent 500-600W PSU isn't much more than $50-$60, so it's a worthwhile upgrade if it gets you 3-4 years of use. An old PSU at peak power could tank at any moment.…
Hello guys. About time I put some new parts in this computer. Will be getting new CPU, Motherboard and RAM. Going to keep the rest as I can't afford it atm. I've read other threads about upgrades and trying to keep it simple but just wanted to make sure I am not doing something wrong. Older parts that I am keeping are: -…
I'll give you one caveat to think on. If that 400W PSU is running at peak or near peak output, it's going to reduce it's lifespan. You should calculate how much wattage each component uses, add it up, and add another 100W for buffer. The time you strain the PSU the most is at power-on time. All the components turn on at…
I forgot to update this thread. Last week I got my new parts in : core i5 2500 GA-P67-DS3-B3 2x4 GB Kingston DDR3 1600 and I also got new PSU as suggested above Cooler Master 500 W Everything is a lot quicker now. I should have done it long time ago but I was feeling ok with my old rig. Now I see the difference. I don't…
First off, my math was not completely wrong, just the part on efficiency. And you accuse me of exaggerating. The machine will draw 436W at peak demand. It might not be the norm, but why chance it? It's best to prepare for the worst than to just cut corners. You're taking my point about peak power and applying it as if it's…
