In the spirit of good timing, my 750w PSU went up in an impressive display of smoke 40 mins ago, luckily the built in fail safes within the PSU and Motherboard saved my system from being fried. I have a 650w psu unopened lying around which I have just installed. I know for my current build this PSU is more than suitable for my current setup, my question is - will this be suitable for the upgrades I have planned for next month which will be the following;
ASUS (Insert random letters/numbers here) Micro ATX Motherboard (Current Motherboard)
AMD FX-8350 Octo-core 4ghz processor (Upgrade from AMD FX-4100 Quad Core @3.8Ghz) (Will have a new heatsink with a 120mm fan)
8GB Ram @ 1333mhz (2x 4GB sticks)
EVGA GTX980Ti 6GB Super clocked (Upgrade from EVGA GTX660 SC)
x2 1TB WD HDD (SATA 7200rpm)
x4 System Fans (120mm)
So question is, will the 650w but enough to keep things running smooth or do I need buy another 750w psu which I would rather avoid at the moment as I am pushing my budget as it is!
It looks like max potential load for your card is around 280watts.
I'm personally running an AMD 8350 with a Radeon R9 290X. I'm currently using an 850w PSU. I've been stable with anything I've thrown at the system thus far. With the power saving that you are getting over my system in the form of that Nvidia card, I'd say 650w would likely be fine. The PSU is a pretty important component. So I tend to overspend a bit for the peace of mind. I'm running an 80plus Gold certified unit. If you are going to run a lower wattage output, I'd suggest you invest in something that is at least 80plus Bronze. If your current PSU meets that standard then I wouldn't worry.
Here's a site with a list of the best ranked and rated power supplies.
I will have to take some time later today to run a wattage test on my system to see how many watts it pulls from the outlet. I know my system before I got a 980 Ti pulled around 350 watts under max load, and the idle was around 100 or so.
I think 650W should be good enough to run that safely. I would avoid any overclocking if I were you.
I just checked my wattage, and right now at idle it is still pulling 100 watts. About 120 or so while browsing internet. And during games it goes around 300-360, depending on how much load the GPU is under. I am very pleased with how this is handling.
For an 8350, add another 50-80 watts and that's how much it would pull. However on a bronze it might be slightly more.
Unless you plan on actively using it to save money, chances are you won't save much by buying it and monitoring stuff with it. Best off to google how many watts stuff use.
If you do plan on buying this device make sure you do not use it for extended periods of time, it is not rated to be plugged in forever. Use it to check watts, then shut down stuff and unplug it.
Thanks dude, but I'm gonna have to pass on it. I just know my current GPU requires around 250W-350W, and what I'm looking at as an upgrade is somewhere around that arena. (Radeon R7 260 -> Radeon R9 390)
Guess I'll have to see what my exact wattage is, mostly for more building in the future
