StanicEnemy · Sep 19, 2017

Hello I currently have this pc chasis

My psu is 400watt came with pc chasis that i bought 3 years ago and now i want to upgrade my pc chasis to this

I want to remove that psu and install it to new pc chasis is it possible? also the pc chasis has 8 fan slots that i can install fans.

The question is 400 psu will be enough to run 8 fans also my system without a issue?

the wattage of the PSU has nothing to do with the case. Your PC is one upgrade away from the 400W not being sufficient, added to this that PSUs that come with cases are normally poor and i'd suggest that you upgrade your PSU whilst moving to the new case.

As to your thought about fans, i'd suggest with the system that you have, 1 intake and 1 exhaust fan will be plenty, the additionally fans will provide a very very slight benefit at the cost of a lot of noise.

Looks like a std atx sized psu to me.

All the other advice still stands, unless you have a heavily OCd cpu and a much more powerful gpu maybe in SLI then you don't need 8 fans, I'm running an OCd 3570k and a 970 and only have 2 intake and 1 exhaust. And your PSU needs replacing.

i have been using my psu for 3 years without a problem.

How exactly are you measuring the subtle long-term damage from ripple and poor voltage regulation? Junk PSUs don't just manifest their crappiness by not turning on or setting a cool fire.

The PSU is the most important part of your PC. To leave a junky one in for an upgrade is the PC equivalent of not getting your worn-out brakes fixed because you want a moonroof.

Your PSU will be junk, it will be a problem come any upgrade to a more powerful component. It might be so borderline that more fans will tip it over the edge.

thanks! what psu would you recommend me to buy?

13thmonkey · Sep 19, 2017

if you only intend to have a single GPU then a good quality 600W PSU would be fine, prior to vega I would have said 500W, but vega has lifted the power requirements back to older levels. Something from Seasonic would be a good choice.

13thmonkey :

is corsair,cooler master and evga bad choice?

13thmonkey · Sep 19, 2017

depends on precisely which models, some are poor (very poor), some are excellent, that's why I plump for seasonic.

What are the amps on the 12V rails from the rating plate on your PSU?

StanicEnemy · Sep 19, 2017

13thmonkey :

all i want is a good psu that has 80 plus thing that will carry me for a very very long time.

Here is the picture of my stock psu

is this really bad?

13thmonkey · Sep 19, 2017

so most of the power consumption is on the 12V rails, you have a maximum of a 260W, so that looks like a 280-300W PSU to my mind. With cheaper PSU's those values are often overstated, the fact that there is a big difference between 260 and 400 is a very bad sign.

13thmonkey :

so that means the psu i have is really at its limit? and it can damage my pc parts any time?

Would you recommend me some psu,is EVGA 600B Bronze good choice?

13thmonkey · Sep 19, 2017

yep, very close to the limit, if not already beyond.

It's OK, not great, just ok. https://www.hardocp.com/article/2016/04/28/evga_600b_entry_level_power_supply_review/9

StanicEnemy · Sep 19, 2017

13thmonkey :

im not gonna go for evga then.

Please recommend 600w +80 bronze psu i have 280 Turkish Lira

13thmonkey · Sep 19, 2017

The one you suggested is just one of EVGA's options, it's at the very bottom of their range. I'm not going to hunt through turkish websites for you, you'll need to give me some options, although I thought you already had given me options.

Edit, missed the 'not'. It's good enough as a PSU, it'll last, it's not very very good, but it's way above 'bad'. Seasonic would still be good.

is 400 psu enough for a new pc case?
