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.
You're very welcome bud :)
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!
i have a Corsair HX650 and an Antec TruePower 650 psu for both my rigs.
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...
