content: Without knowing what's inside your PC there's no way of knowing how much power it may need.If you are running a grand total of 600watts with your CPU, GFX card(s), fans, hard drives, etc then the 400 watt PSU will not be sufficient.If your grand total is below 350 (wriggle room so you aren't stressing it at max output) then the 400 may be enough - assuming the 5V and 12V rails are sufficient for their requirements.Do the maths:http://www.coolermaster.com/power-supply-calculator/

content: Bad news.Your old psu was 600 watts and had two power cables that plug into the motherboard to power the cpu.Your new psu is 400 watts, loss of 200 watts. And there is no mention of what power cables are available.For example. My Core 2 cpu (E6600, E8200, Q6600) require a 24 pin main motherboard power and also require an additional separate 4 pin power connector that also plugs into motherboard.Conclusion. Either the website where you shop is crap. PSU is crap. Or both are crap.One more thing. My rule of thumb is to always buy psu that is 500 watts or more.

content: Dont buy crappy no name ATX PSU's...Get a Seasonic S12 or an EVGA or a Corsair or something that is decent, unless you are running an i7-6950x plus SLI Titan X's you wont need more than 450Watts of DECENT power supply.

I'm very well versed in computer hardware, and I know what I'm talking about.

content: So thats 95Watts IF/WHEN you stress test the CPU, with some OC, bump it to 110-130Watts, account 20Watts for the mobo/RAM, 8Watts for each HDD/SDD, with 4 HDD's/SSD's you end up with a stress test consumption of 147Watts at stock and around 180Watts with some OC.With a decent PSU with 450Watts that still leaves you 450-180 = 270Watts, enought juice for any GPU known to man..Seasonic in Europe are the "cheapest" name brand decent PSU's 450Watts will cost you around 50€, if you want over 300Watts of headroom grab the 520Watts edition for 60-70€, just dont use crappy PSU that cant output half of their rated power before exploding or the rails saging 1v and then complain that your computer is unstable and BSOD's everytime you open word.

content: Well that may bump it up a bit. I think my power supply wrote me a personal thank you when I replaced my GTX480 with a 970. But around 500 watts should be plenty. Stick with a quality name like Seasonic.

content: Quote from: sony mavica on March 31, 2017, 12:44:32 amThen the PSU you've asked about would be fine. however, I'd recommend you spend a bit more, and get this one instead:https://www.elive.co.nz/fsp-hyper-500w-atx-power-supply.phpBetter specs, efficiency, and significantly longer warranty (5 years vs 1!)Quote from: rrinker on March 31, 2017, 12:54:04 amFSP is a quality PSU brand FYI.It may not be the most popular one, but definitely a good brand.

content: Went searching, OK, its not a bottom of the barrel PSU:https://en.wikipedia.org/wiki/FSP_GroupBut it was used and is used in OEM's, and I've seen a pile of FSP branded PSU's, thats why I'm a bit leery, those where core2duo era PSU's, maybe affected by the capacitor plague of those times?

content: I've observed a lot of wattage inflation in PCs over the past 10 years or so. I've measured my core i7 desktop and it peaks at under 200W from the wall and idles around 120W. When I built it I had a hard time even finding a power supply under 500W.

content: Because every OEM pc as a crappy PSU, so Nvidia and AMD started to recommend things like 500-600Watts PSU's for their graphics cards to kinda be sure that the no name low quality PSU's wont explode at the first power on.Then everybody thinks that the GPU alone uses those recommended 500-600Watts and they add the cpu TDP on that, and you end up with the stupidness of 1500Watts PSU's in systems that use 600Watts or less full stress test.That or they all knew that in the future pc cases would be more akin to discos with 1kW of leds in them..

content: Gamers don't understand computer hardware, they just know bigger numbers are better. That really explains most of it.I got mass downvoted on reddit for saying you should probably use at least a little bit of ESD protection when handling RAM, as it's one of the more sensitive components (And also one of the highest "Out of the box" failure rates, which gamers assure me is pure coincidence)

content: I believe it. I've personally killed a stick of RAM at least once due to careless handling that resulted in a small static discharge. RAM is also the only computer part I have ever had that was faulty right out of the box even with proper handling.
