How to accurately calculate power draw and choose a fitting power supply - Page 5

Your system is probably pulling a little over 750w from the PSU then
post #42 of 50
You should always buy a beefier power supply. You should always splurge and get the best power supply you can. Overkill within reason is good.

The PSU is the easiest PC component to future proof. It is the one component where technology does not move fast.

When I bought my Corsair 620HX, it was way overkill for my 8800 gt back in 2007. But 4 years later it is still with me and will be with me for my next build that will last another 2-3 years. Now they come with 7 year warranties.

Anyone buying a PSU today for a gaming rig that thinks they will continue to upgrade the rig should go at least 850 watts. Yes, I said 850 without looking at the components because the next 2-3 generation gpus are going to be monsters.

BTW, if you're somebody who likes to buy and sell things constantly, then forget what I said. I like to buy it once and then own it for as long as possible.

PSUs have changed more since the year 2000 than CPUs have. CPUs still use x86; today's PSUs have entirely different electrical standards, topologies, components (do you know how much power transistors alone have advanced?), design philosophies, features, and connectors.

Even since 2006, there have been major, major changes, with the introduction of the 80PLUS standards, introduction of multi-rail OCP, beginning adoption of EPS12V connections and standards, the ubiquity of SATA, the continued shift toward increased +12V current, higher standards for electrical output characteristics, adoption of modular cable systems, move from 80mm fans to 120-140mm fans, new topologies, and vastly lower prices.

You could buy a PC Power & Cooling Turbocool 1200W five years ago for $500 and it was the best thing around; today you can buy PSUs that completely outclass it in every possible way for $200.



Bigger isn't always better.

Comparing a 1200 watt psu 5 years ago is not really applicable to my point when I'm talking about a 600 watt psu that was overkill in 2007.

My point is that you shouldn't buy a psu that is just enough for the system you are building if you plan to upgrade in the future.

So if 500 watts is enough and you plan to stay in this hobby, then splurge for the best power supply and up the wattage with headroom.

A well-bought PSU will outlast your cpu in terms of tech and durability. That makes it easily future proofed. Who's still running a core 2 duo from 2007 with high-end components today (6950, ddr3, etc.)... but plenty are running a psu from 2007 with high-end components today.

Go big on the PSU (within reason). For example, if I were to buy a psu for the rig in my sig, I would go with an 850 watt psu.

You're both right with your own reasons. I've gone through so many PSU's and learnt along the way, hopefully others just buy right the first time. I started with an A-Power (junk), then a SHAW (really junk) and a few other random ones (junk), A Thermaltake (less junk), an OCZ (average) and now the Silverstone. I like the Silverstone the best so far

For the record, I have a 2007 Core 2 Quad and will be purchasing an HD6950 shortly.

I have a 6850 paired with my old E8400 as my secondary system.
You asked.

Wow, you guys missed my point. Instead of pointing out 1 sentence, look at the idea I presented.

BTW, I meant more along the lines of the original c2d....E6400, E6300 line. Processors that were released alongside the 620HX.
