What Size Power Supply Should I Get?

Thanks for the video. I'm saving up for a better psu. The cheap Bestec 250w is running fine but since I'm now pulling 243w at full load I'm really concerned.

The bigger, the better, but...there are 550W that provide max 350w in reality and other 550w PSU that provide over 650w in real life! My recommendation is a minimum 10-15% over-sized brand PSU, 12v monorail, active PFC, good efficiency (minimum 80 Bronze), 120/140mm cooling fan, sleeved wires.
I have a Corsair wx450W (Seasonic inside, 80 Bronze, 12v monorail @33Ampers) and my system I think draws maximum 350w at full load!

Ya, I can agree. When I built my PC it was the first one I did and didn't know entierly what I was doing when buying all the parts.

When using the calculator, I did factor in 20% capcitor aging, plus a ton of extra hardware I wanted to add but havent got around to yet. It all came out to around 900w.

Still, if I ever want to build an almost eniterly new PC, I should still be able to use that power supply, tho I have never done the OCCT stress test to see what my system actually draws. It's probably not that much. lawl.

That shoots a tad high, and does not even account for my OC on my SLI 680's. I am using an 800 watt CM Silent Pro Gold that pulls 700-750 watts from the wall using OCCT GPU + CPU stress test according to my batter back up's display. The calculator calls for an almost 900 watt PSU.

I also used that calculator.

I ended up with an Enermax revolution 920w 80 plus silver. It might be a little overkill for what I have on my sysyem now but I have plenty of room to add more hardware/upgarde or overclock later on, plus that PSU has a 5 year warranty. :D

I bought a Corsair AX-750. 80+ Gold unit. 90% efficient unit. While gaming, I am pulling about 380-445W depending on the game with my setup. That is putting me at 50% to 60% of the power supply rating which is the ideal power efficiency. I can put another GPU on and be at 70%. However, that is the highest I would want to go for efficiency reasons.

This is a great topic for someone starting off. So easy for someone to skip for that cheaper PSU. My Corsair AX-750 has a 7 year warranty. Plus I got my AX-750 for $120 on a sweet sale. Awesome...
